In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0055] The present embodiment provides a PCBA assembly and welding integrated production line, which can be used to assemble an electric energy meter. Specifically, the PCBA assembly and welding integrated production line can install a circuit board into a base and weld the circuit board.

[0056] like Figure 1 As shown, the PCBA assembly and welding integrated production line includes a conveying device 10, which includes a conveying mechanism 11 and a plurality of carriers 12 capable of positioning the base of the electrical product. The carrier 12 is compatible with at least two types of bases. The conveying mechanism 11 is arranged in a ring and can drive the carrier 12 to move along its ring path. The ring path is provided with a loading assembly station, a welding station and a unloading sorting station from upstream to downstream. The loading assembly station includes a base loading mechanism 20 located upstream of the ring path, a circuit board loading mechanism 30, a base handling module 107 located between the base loading mechanism 20 and the circuit board loading mechanism 30, a circuit board handling module 108 and a plurality of first functional modules. The base handling module 107 is used to transfer the base on the base loading mechanism 20 to the corresponding carrier 12, and the circuit board handling module 108 is used to transfer the circuit board on the circuit board loading mechanism 30 to the corresponding base. The welding station includes a plurality of welding manipulators 106 located in the middle of the ring path for welding the circuit board. The unloading and sorting station includes a welding detection mechanism 80 located downstream of the circular path, a finished product unloading mechanism, a defective product unloading mechanism and a plurality of second functional modules.

[0057] In the electric meter PCBA assembly welding integrated production line of this embodiment, the conveying mechanism 11 can convey the carrier 12 in sequence along the circular path, so that the base handling module 107, the circuit board handling module 108, a plurality of first functional modules, the welding manipulator 106, the welding detection mechanism 80, the finished product unloading mechanism, the defective product unloading mechanism and the second functional module can respectively operate the base or the circuit board on the carrier 12. Since the conveying path of the conveying mechanism 11 is circular, it is equivalent to folding the entire conveying line, avoiding the PCBA assembly welding integrated production line from being too long, making the structure of the entire production line more compact, and facilitating the reasonable layout of the workshop space. In addition, the circular path realizes the automatic circulation of the carrier 12, and there is no need to manually transport the carrier 12 from the tail end to the beginning of the production line, thereby reducing the production cost. In addition, by setting a plurality of welding manipulators 106, different positions on the circuit board can be welded respectively, thereby improving the tooling beat of the PCBA assembly welding integrated production line and improving the production capacity; in addition, the production line of the utility model integrates assembly, welding and detection, and has complete functions and a high degree of automation.

[0058] In this embodiment, two positioning grooves are provided on the carrier 12, and the two positioning grooves match the shapes of the two bases respectively, so as to position the two bases respectively. Optionally, the two positioning grooves can be arranged flat in the horizontal plane, or can be arranged in a stacked manner in the vertical direction, which is not specifically limited here. Figure 1 As shown, the conveying mechanism 11 is installed on the workbench, and the annular path formed by the conveying mechanism 11 is a quadrilateral, so that the inner space and the outer space of the conveying mechanism 11 are relatively regular, which is conducive to the arrangement of other structures. In other embodiments, the annular path can also be circular, quadrilateral, elliptical, runway-shaped, etc. Specifically, the conveying mechanism 11 includes a quadrilateral track and a driving mechanism, and the driving mechanism can drive multiple carriers 12 to move synchronously on the quadrilateral track. Optionally, the driving mechanism includes four driving sources, and the four driving sources drive the carriers 12 to move on the four sides of the quadrilateral track respectively. Each driving source is detachable from the carrier 12 on the corresponding side of the track. When the carrier 12 needs to turn, the previous driving source is separated from the carrier 12, and the latter driving source is matched with the carrier 12. Its specific structure can be any one of the prior art, and is not specifically limited here.

[0059] like Figure 1 and Figure 2 As shown, the base loading mechanism 20 includes a base loading manipulator 22, a base stacking area 21 and a base conveyor belt 23. Among them, the base loading manipulator 22 is arranged outside the workbench of the conveying device 10, and the base loading manipulator 22 can rotate relative to the circumferential direction. Specifically, the circumferential direction is the circumference in the horizontal plane. The base stacking area 21 is arranged on the side of the base loading manipulator 22 away from the conveying device 10, and is used to place the base of the electrical product; the base conveyor belt 23 is arranged below the base loading manipulator 22, and is arranged perpendicular to the conveying direction of the conveying mechanism 11 in the upstream area of ​​the circular path. The base conveyor belt 23 is connected to the conveying mechanism 11 and is partially located on the workbench. The base loading manipulator 22 can grab the base from the base stacking area 21 and place the base on the base conveyor belt 23. The base conveyor belt 23 transports the base to the vicinity of the base handling module 107. The base handling module 107 then grabs the base on the base conveyor belt 23 and places it in the carrier 12 located at the base handling module 107. By arranging the base conveyor belt 23 to be partially located on the workbench, it is convenient for the base transport module 107 to grab the base.

[0060] In this embodiment, the loading of the base is realized by two driving structures, namely, the base loading manipulator 22 and the base handling module 107, so that the trajectory of each driving structure driving the base movement can be shortened. The two driving structures work simultaneously, which is conducive to speeding up the loading rhythm of the base, thereby enabling the PCBA assembly and welding integrated production line to meet higher production capacity requirements. Optionally, the base loading manipulator 22 can be an existing four-axis manipulator with a clamping component. The base handling module 107 can be a structure composed of a horizontal linear module, a vertical linear module and a clamping component. Since the handling trajectory of the base loading manipulator 22 is more complicated than that of the base handling module 107, each handling time is relatively long. Preferably, in this embodiment, the base loading manipulator 22 is set to grab multiple bases at a time, and multiple bases are placed on the base conveyor belt 23, and each base is then moved to the base handling module 107 in sequence through the base conveyor belt 23, so as to ensure that the handling of the base loading manipulator 22 matches the action rhythm of the base handling module 107, and ensure the production capacity of the PCBA assembly and welding integrated production line.

[0061] like Figure 1 and Figure 2 As shown, the circuit board feeding mechanism 30 includes a circuit board feeding manipulator 32, a circuit board stacking area 31 and a buffer area 33. The circuit board feeding manipulator 32 is arranged outside the workbench of the conveying device 10, and the circuit board feeding manipulator 32 can rotate relative to the circumferential direction. Specifically, the circumferential direction is the circumference in the horizontal plane. The circuit board stacking area 31 is arranged on the side of the circuit board feeding manipulator 32 away from the conveying device 10, and the circuit board stacking area 31 is used to place the circuit board. The buffer area 33 is arranged below the circuit board feeding manipulator 32, the buffer area 33 is connected to the conveying mechanism 11 and is partially located on the workbench, and a plurality of positioning fixtures 331 for positioning the circuit board are arranged flatly in the buffer area 33. The circuit board feeding manipulator 32 grabs the circuit board from the circuit board stacking area 31 and places the circuit board in the positioning fixture 331 of the buffer area 33, and the circuit board handling module 108 grabs the circuit board from the positioning fixture 331 and places the circuit board in the base of the carrier 12 located at the circuit board handling module 108.

[0062] In this embodiment, the feeding of the circuit board is realized by two driving structures on the circuit board feeding manipulator 32 and the circuit board handling module 108, so that the trajectory of each driving structure driving the circuit board can be shortened. The two driving structures work at the same time, which is conducive to speeding up the feeding rhythm of the circuit board, thereby enabling the PCBA assembly and welding integrated production line to meet higher production capacity requirements. In addition, the positioning fixture 331 in the buffer area 33 can correct the posture of the circuit board in advance, so as to ensure that the circuit board handling module 108 can accurately install the circuit board in the carrier 12 located at the circuit board handling module 108. Optionally, the circuit board feeding manipulator 32 can be an existing four-axis manipulator with a clamping assembly. The circuit board handling module 108 can be a structure composed of a horizontal linear module, a vertical linear module and a clamping assembly. Since the handling trajectory of the circuit board feeding manipulator 32 is more complicated than the handling trajectory of the circuit board handling module 108, each handling time is relatively long. Preferably, the circuit board loading robot 32 can place multiple circuit boards on multiple positioning fixtures 331 arranged flat at one time to ensure that the circuit board handling module 108 can grab the circuit board every time it moves, that is, to ensure that the movement of the circuit board loading robot 32 matches the movement rhythm of the circuit board handling module 108, thereby ensuring the production capacity of the PCBA assembly and welding integrated production line.

[0063] like Figure 1 and Figure 2 As shown, the first functional modules include a dust removal module 40, a base detection module 50, a code scanning module 60 and a circuit board detection module 70. The dust removal module 40 is used to remove dust from the base in the carrier 12, the base detection module 50 is used to detect the relative position of the carrier 12 and the base, the code scanning module 60 is used to scan and communicate the barcode on the circuit board, and the circuit board detection module 70 is used to detect and judge the assembly position of the base and the circuit board.

[0064] Specifically, Figure 2 As shown, the dust removal module 40 is mounted above the conveying mechanism 11 and close to the position of the base feeding mechanism 20. On the one hand, the dust removal module 40 will not occupy the space on both sides of the conveying mechanism 11 along the conveying direction, making the overall structure of the PCBA assembly and welding integrated production line more compact. On the other hand, it is ensured that the dust removal module 40 can conveniently remove dust from the base just placed on the carrier 12. Optionally, the dust removal module 40 includes a dust removal hood, which is arranged above the conveying mechanism 11 and opens downward, and the dust removal hood is connected to an external air blowing device. When the air blowing device is working, the dust removal hood blows air to the base below it, thereby achieving dust removal of the base.

[0065] like Figure 2As shown, the base detection module 50 is arranged on the workbench of the conveying device 10, and the base handling module 107 and the base detection module 50 are arranged in sequence along the conveying direction of the upstream area of ​​the circular path. The conveying mechanism 11 first drives the unloaded carrier 12 to move to the base handling module 107, so that the base handling module 107 can place the base in the base feeding mechanism 20 in the carrier 12; then the conveying mechanism 11 drives the carrier 12 and the base to move to the base detection module 50, so that the base detection module 50 can detect the placement position of the base. Optionally, the base detection module 50 includes a trocar comparison piece and a CCD detection component, and the trocar comparison piece is provided with a positioning hole, and the base is provided with a marking point corresponding to the positioning hole. When the carrier 12 drives the base to move to the base detection module 50, the base is located below the trocar comparison piece. At this time, the CCD detection component takes a photo of the trocar comparison piece and the base, and determines whether the base is placed in place by analyzing whether the marking point on the photo is aligned with the positioning hole. If the base detection component determines that the base is not in place, it will issue a prompt message to facilitate the staff to correct the base position. If the base detection component determines that the base is in place, it can also issue a prompt message to facilitate the staff to confirm. In other embodiments, the base detection module 50 can be any existing structure that can detect whether the base is correctly placed relative to the carrier 12, and is not specifically limited here.

[0066] like Figure 2 As shown, the code scanning module 60 is arranged on one side of the conveying mechanism 11 and is located between the circuit board feeding mechanism 30 and the circuit board handling module 108. In the process of transporting the circuit board from the circuit board feeding mechanism 30 to the conveying mechanism 11, the circuit board handling module 108 passes through the code scanning module 60 to facilitate the code scanning communication between the PCBA assembly and welding integrated production line and the circuit board. Specifically, the content of the code scanning communication is not limited to the batch number, production time and other information of the circuit board. It should be noted that the code scanning module 60 is an existing component, and its specific working principle will not be repeated here.

[0067] like Figure 2As shown, the circuit board detection module 70 is arranged on the workbench of the conveying device 10, and is close to the position of the circuit board handling module 108. The circuit board detection module 70 and the circuit board feeding mechanism 30 are respectively located on both sides of the conveying direction of the upstream area of ​​the circular path. The above-mentioned setting is not only convenient for the circuit board detection module 70 to detect the circuit board just placed on the base, but also makes full use of the space inside and outside the conveying mechanism 11, which is conducive to improving the structural compactness of the PCBA assembly and welding integrated production line. Specifically, when the circuit board detection module 70 detects that the circuit board is not placed in place, it can issue a prompt message that it is not in place, and the staff can manually adjust the position of the circuit board to ensure that the circuit board and the base are in place, thereby ensuring the accuracy of subsequent welding. Of course, when the circuit board detection module 70 detects that the circuit board is placed in place, it can also issue a prompt message that it is in place, so that the staff can confirm it. Optionally, the base detection module 50 includes a CCD detection component, and the CCD detection component can take a photo of the base and the circuit board, and determine whether the circuit board and the base are in place by analyzing the feature points on the photo. If it is not in place, a prompt message is issued to facilitate manual correction of the circuit board position. In other embodiments, the circuit board detection module 70 can be any existing structure that can detect whether the circuit board is correctly placed relative to the base, and no specific limitation is made here.

[0068] In summary, the working process of the loading and assembly station of the PCBA assembly and welding integrated production line is as follows:

[0069] The conveying mechanism 11 conveys the carrier 12 along its circular path;

[0070] First, the conveying mechanism 11 conveys the empty carrier 12 to the base transfer module 107, and the base transfer module 107 places the base on the base conveyor belt 23 onto the carrier 12;

[0071] Next, the conveying mechanism 11 conveys the carrier 12 and the base together to the bottom of the dust removal module 40, and the dust removal module 40 removes dust from the base;

[0072] Next, the conveying mechanism 11 conveys the carrier 12 and the dust-free base to the base detection module 50, and the base detection module 50 detects the placement position of the base. If the base is not placed in place, the staff will adjust it. If it is placed in place, the conveying mechanism 11 conveys the carrier 12 and the base to the circuit board handling module 108;

[0073] Next, the circuit board handling module 108 grabs the circuit board from the positioning fixture 331 and transports the circuit board to the code scanning module 60 for code scanning, and finally places the scanned circuit board in the base on the carrier 12 at the circuit board handling module 108;

[0074] Next, the conveying mechanism 11 conveys the carrier 12 with the circuit board to the circuit board detection module 70. The circuit board detection module 70 detects the placement position of the circuit board. If the placement is not in place, the staff will adjust it. If the placement is in place, the conveying mechanism 11 will continue to convey the carrier 12 and the base and circuit board thereon to the welding station.

[0075] like Figure 1 and Figure 3 As shown, the conveying mechanism 11 forms a first U-shaped conveying line in the midstream area, and some welding manipulators 106 are arranged on the inner side of the first U-shaped conveying line, and some welding manipulators 106 are arranged along the outer side of the first U-shaped conveying line. The above arrangement makes the arrangement of multiple welding manipulators 106 more compact, thereby shortening the total length of the conveying mechanism 11 and improving the structural compactness of the PCBA assembly welding integrated production line. In this embodiment, the welding manipulator 106 includes a four-axis manipulator and a welding gun, and the four-axis manipulator drives the welding gun to move to a specified position, and the welding gun welds the circuit board. Optionally, in this embodiment, the PCBA assembly welding integrated production line includes eight welding manipulators 106, and each welding manipulator 106 welds two welding positions on the circuit board. In some embodiments, the PCBA assembly welding integrated production line includes sixteen welding manipulators 106, and each welding manipulator 106 welds one welding position on the circuit board, thereby doubling the operation cycle. In other embodiments, the number of welding manipulators 106 can be increased or decreased according to actual needs, and is not specifically limited here.

[0076] like Figure 1 and Figure 4 As shown, the second functional module of the unloading and sorting station includes a cleaning module 90, which is used to clean the welded circuit board and base to prevent residual welding slag from affecting the normal operation of the circuit board. Preferably, the cleaning module 90 and the welding detection mechanism 80 are arranged in sequence along the conveying direction of the conveying mechanism 11 in the unloading and sorting station, that is, the cleaning module 90 is set at the position closest to the welding station, so that after the circuit board is welded, the circuit board is cleaned first and then inspected to prevent foreign matter such as welding residue from affecting the detection result of the welding detection mechanism 80. Optionally, the cleaning module 90 includes a driving structure and a brush, and the driving structure can drive the brush to move up and down to approach the circuit board, and the driving structure can also drive the brush to rotate or reciprocate horizontally to clean the circuit board. In other embodiments, the cleaning module 90 can also be other structures that can clean the assembly.

[0077] Optionally, the welding detection mechanism 80 includes a visual acquisition component, which acquires the image of the circuit board delivered to the welding detection mechanism 80 through the visual acquisition component, thereby judging whether the solder joints at each welding position are qualified. In some embodiments, the welding detection mechanism 80 also includes a lifting drive component and a test probe, and the lifting drive component drives the test probe to contact the solder joints on the circuit board, thereby performing an electrical test on the circuit board. It is understandable that the specific structure of the welding detection mechanism 80 can be adjusted according to the parameters to be detected, and is not specifically limited here.

[0078] Preferably, the finished product unloading mechanism and the defective product unloading mechanism are both electrically connected to the welding detection mechanism 80, and the finished product unloading mechanism and the defective product unloading mechanism can carry the base and the circuit board moved to the corresponding position based on the detection result of the welding detection mechanism 80. Specifically, the conveying mechanism 11 conveys the carrier 12 to pass through the welding detection mechanism 80, the finished product unloading mechanism and the defective product unloading mechanism in sequence. If the welding detection mechanism 80 detects that the circuit board on the corresponding carrier 12 is welded properly, then when the carrier 12 moves to the finished product unloading mechanism, the finished product unloading mechanism removes the base and the circuit board on the carrier 12 from the carrier 12, and then the empty carrier 12 passes through the defective product unloading mechanism and then moves to the loading assembly station for recycling. If the welding detection mechanism 80 detects that the welding of the circuit board on the corresponding carrier 12 is unqualified, the finished product unloading mechanism will not operate when the carrier 12 moves to the finished product unloading mechanism. When the carrier 12 drives the base and the circuit board to move to the defective product unloading mechanism, the defective product unloading mechanism will remove the unqualified circuit board and base from the carrier 12, and then the empty carrier 12 will move to the loading and assembly station for recycling.

This arrangement not only further improves the structural compactness of the PCBA assembly and welding integrated production line, but also makes the overall occupied space of the PCBA assembly and welding integrated production line more regular.

[0082] like Figure 1 and Figure 4As shown, the second functional module of the unloading and sorting station also includes an anti-static module 105, which is arranged on the side of the conveying direction of the finished product conveying module 102, so as to facilitate the removal of static electricity from the qualified circuit boards and bases. Preferably, the PCBA assembly and welding integrated production line includes at least two anti-static modules 105, which can ensure a good anti-static effect on the assembly parts on the one hand, and on the other hand, can improve the working rhythm of the PCBA assembly and welding integrated production line to meet the needs of high production capacity.
