Description

Technical Field

[0001] This invention relates to the field of machine tools, and in particular to a device for applying a coating pin. Background Technology

[0002] Before encapsulating and pinning the circuit boards, multiple circuit boards are stacked sequentially. The drilling machine can drill multiple circuit boards simultaneously to improve processing efficiency. The encapsulation and pinning equipment is used to wrap adhesive tape around the outside of a board assembly formed by stacking aluminum plates, multiple circuit boards, and bakelite boards to secure the assembly. It also installs pins on the assembly to position it in the drilling machine. Before encapsulation and pinning, the aluminum plates, circuit boards, and bakelite boards need to be pre-stacked sequentially. Then, the operator places the stacked assembly into the preset processing position on the encapsulation and pinning equipment, which automatically encapsulates and pins the assembly.

[0003] In existing related technologies, during the use of encapsulation and pinning equipment, production personnel need to align the stacked sheet metal groups with the preset processing area of ​​the equipment before placing them on it. After the equipment fixes the sheet metal groups within the preset processing area, it can simultaneously encapsulate each edge of the sheet metal group and then automatically pin them. When the radial dimension of the sheet metal is too large, it is difficult for production personnel to move the sheet metal groups, making it difficult to accurately position the sheet metal groups in the preset processing area, increasing the positioning time of the sheet metal groups, and affecting the processing efficiency of the encapsulation and pinning equipment. Summary of the Invention

[0004] In order to reduce the time for encapsulation and pinning of circuit boards, improve the efficiency of encapsulation and pinning of circuit boards, and increase the yield of circuit boards, this application provides an encapsulation and pinning device.

[0005] The coating and pinning device provided in this application adopts the following technical solution: A coating and pinning device includes an operating table, the upper surface of which is configured as a support surface. The edge of the operating table is provided with a first limiting edge, a second limiting edge, a third limiting edge, and a fourth limiting edge. The first and second limiting edges are adjacent to each other and perpendicular to each other, as are the third and fourth limiting edges. All four limiting edges are adapted to engage with a sheet metal assembly. A support mechanism is disposed on the support surface and used to support the sheet metal assembly. A coating mechanism group includes a first coating mechanism and a second coating mechanism. The first coating mechanism is disposed outside the first limiting edge. The two coating mechanisms are located outside the second limiting stop edge. Both the first and second coating mechanisms are used to coat the corresponding edges of the sheet metal group with glue after the sheet metal group stops against the first and second limiting stops edge. The upper pin mechanism is located downstream of the coating mechanism group along the feeding direction of the coating and upper pin equipment. The upper pin mechanism has a drilling component, an upper pin component, and a first driving component. The upper pin mechanism is located outside the third limiting stop edge. The first driving component is used to drive the upper pin component to approach the sheet metal group. The drilling component and the upper pin component are used to drill holes and upper pin the sheet metal group after the sheet metal group stops against the third and fourth limiting stops edge.

[0006] By adopting the above technical solution, the sheet metal assembly can be positioned before overmolding or pinning by having workers push it to simultaneously engage with the first and second limiting stops, or simultaneously with the third and fourth limiting stops. Compared with the prior art, for sheet metal of any radial size, the overmolding and pinning equipment of this application can reduce the positioning time of the sheet metal assembly, thereby improving the processing efficiency of the overmolding and pinning equipment. In addition, by separating the overmolding mechanism and the pinning mechanism, the structural complexity of the overmolding and pinning equipment is reduced, thereby reducing the production cost of the overmolding and pinning equipment. Furthermore, since the positioning method of the sheet metal assembly in this application is less difficult, the overmolding and pinning equipment has higher processing efficiency when the sheet metal assembly is positioned multiple times.

[0007] Preferably, the support mechanism includes an air duct, a fan, and multiple ball bearings. The fan is located inside the air duct, which is located inside the operating table. The air duct forms multiple exhaust holes on the support surface. The fan is used to blow air into the exhaust holes, and the exhaust holes are adapted to be opposite to the sheet metal assembly. The multiple ball bearings are arranged in multiple rows and columns and are rotatably disposed on the support surface, and the ball bearings are spaced apart from the exhaust holes.

[0008] By adopting the above technical solution, during the transportation of the sheet metal assembly, the fan introduces air into the air duct, and the air is discharged from the air duct through the exhaust port. When the exhaust port is opposite to the sheet metal assembly, the air blown out by the exhaust port can provide a supporting force to the sheet metal assembly away from the supporting surface, thereby achieving the effect of supporting the sheet metal assembly. At the same time, the ball bearings can support the sheet metal assembly. Through the anti-collision action between the ball bearings and the sheet metal assembly, the contact area between the supporting surface and the sheet metal assembly can be reduced, thereby minimizing the risk of scratches caused by friction between the surface of the sheet metal assembly and the supporting surface during the transportation of the sheet metal assembly.

[0009] Preferably, the operating table further includes a rotating component and a second driving component. The rotating component includes a drive motor and a rotating platform. The rotating platform is located on the support surface and is adapted to be opposite to the sheet metal assembly. The drive motor is connected to the rotating platform. The rotating component is configured such that after the coating mechanism has coated two adjacent edges of the sheet metal assembly, the drive motor drives the rotating platform to rotate the sheet metal assembly, so that the coating mechanism is positioned opposite to the other two adjacent edges of the sheet metal assembly. The second driving component is located inside the operating table and is connected to the rotating platform. The second driving component is adapted to drive the rotating platform to rise or fall along the height direction of the coating pinning device, so that the rotating platform stops or separates from the sheet metal assembly.

[0010] By adopting the above technical solution and setting a rotating component to rotate the board assembly, the coating mechanism can coat all edges of the board assembly with glue, and the time for flipping the board assembly can be reduced. Furthermore, by using a rotating platform to rotate the board assembly, excessive force used by workers during manual rotation can be avoided, preventing bending of the board assembly. It also minimizes the risk of the board assembly contacting the support surface during rotation and scratching the circuit board surface, thereby improving the yield rate and reducing the production cost of the circuit boards.

[0011] Preferably, the first limiting stop edge is provided with a first top support member, and the second limiting stop edge is provided with a second top support member. The first top support member is adapted to extend into or move out of the first limiting stop edge and is adapted to abut against the sheet metal assembly. The second top support member is adapted to extend into or move out of the second limiting stop edge and is adapted to abut against the sheet metal assembly. The third limiting stop edge is provided with a third top support member, and the fourth limiting stop edge is provided with a fourth top support member. The third top support member is adapted to extend into or move out of the third limiting stop edge and is adapted to abut against the sheet metal assembly. The fourth top support member is adapted to extend into or move out of the fourth limiting stop edge and is adapted to abut against the sheet metal assembly.

[0012] By adopting the above technical solution, after the coating mechanism completes coating two edges of the sheet metal assembly, the first support member drives the sheet metal assembly to move away from the first limiting edge along the second direction of the coating and pinning equipment. At the same time, the second support member drives the sheet metal assembly to move away from the second limiting edge along the first direction of the coating and pinning equipment. This increases the distance between the sheet metal assembly and the first limiting edge, and between the sheet metal assembly and the second limiting edge, thereby minimizing the collision between the sheet metal assembly and the first or second limiting edge during rotation. This helps to prevent the sheet metal assembly from colliding with the first or second limiting edge during rotation, thus minimizing the risk of damage to the integrity of the sheet metal or scratches. After the pinning mechanism completes the pinning of the sheet metal assembly, the third support component drives the sheet metal assembly to move away from the third limit stop along the second direction of the overmolding pinning equipment. At the same time, the fourth support component drives the sheet metal assembly to move away from the fourth limit stop along the first direction of the overmolding pinning equipment. This increases the distance between the sheet metal assembly and the third limit stop, as well as between the sheet metal assembly and the fourth limit stop. This helps to minimize the collision between the sheet metal assembly and the third or fourth limit stop during transportation, thus preventing the sheet metal assembly from colliding with the third and / or fourth limit stops during transportation and causing problems with its integrity or scratches.

[0013] Preferably, the overmolding and pinning equipment further includes: a limiting mechanism, the limiting mechanism including at least one limiting member, the limiting member being vertically and movably disposed on the support surface, the limiting member being opposite to and spaced apart from the first limiting stop edge, and / or the limiting member being opposite to and spaced apart from the second limiting stop edge, and / or the limiting member being opposite to and spaced apart from the third limiting stop edge, and / or the limiting member being opposite to and spaced apart from the fourth limiting stop edge, the limiting member being adapted to engage with the sheet metal assembly for abutment.

[0014] By adopting the above technical solution, when the operator pushes the sheet metal assembly closer to the overmolding mechanism assembly, after the sheet metal assembly is engaged with both the first and second limiting edges, the limiting member extends from below the support surface and engages with the sheet metal assembly. The limiting member and the first limiting edge together clamp the sheet metal assembly, and / or the limiting member and the second limiting edge together clamp the sheet metal assembly. Similarly, when the operator pushes the sheet metal assembly closer to the overmolding pinning mechanism, after the sheet metal assembly is engaged with both the third and fourth limiting edges, the limiting member extends from below the support surface and engages with the sheet metal assembly. The limiting member and the third limiting edge together clamp the sheet metal assembly, and / or the limiting member and the fourth limiting edge together clamp the sheet metal assembly, thereby achieving the positioning of the sheet metal assembly by the overmolding pinning equipment.

[0015] Preferably, the limiting mechanism includes a fourth driving member and a fifth supporting member. Both the fourth driving member and the fifth supporting member are disposed within the operating table and are connected to the limiting member. The fourth driving member drives the limiting member to rise or fall along the height direction of the overmolding and pinning equipment, causing the limiting member to extend or retract into the operating table. The fifth supporting member drives the limiting member to move closer to or away from the first limiting edge, causing the limiting member to abut or separate from the sheet metal assembly. Alternatively, the limiting mechanism includes a fifth driving member and a sixth supporting member. Both the fifth driving member and the sixth supporting member are disposed within the operating table and are connected to the limiting member. The fifth driving member drives the limiting member to rise or fall along the height direction of the overmolding and pinning equipment, causing the limiting member to extend or retract into the operating table. The sixth supporting member drives the limiting member to move closer to or away from the second limiting edge, causing the limiting member to abut or separate from the sheet metal assembly. And / or, the limiting mechanism includes a sixth driving member and a seventh supporting member, both of which are disposed within the operating table and connected to the limiting member. The sixth driving member drives the limiting member to rise or fall along the height direction of the overmolding and pinning equipment, so that the limiting member extends out or into the operating table. The seventh supporting member drives the limiting member to move closer to or away from the third limiting edge, so that the limiting member stops or separates from the sheet metal assembly. And / or, the limiting mechanism includes a seventh driving member and an eighth supporting member, both of which are disposed within the operating table and connected to the limiting member. The seventh driving member drives the limiting member to rise or fall along the height direction of the overmolding and pinning equipment, so that the limiting member extends out or into the operating table. The eighth supporting member drives the limiting member to move closer to or away from the fourth limiting edge, so that the limiting member stops or separates from the sheet metal assembly.

[0016] By adopting the above technical solution, when the coating mechanism group coats the sheet metal assembly, the fifth driving member drives the sixth supporting member to rise along the height direction of the coating pinning device, and the sixth supporting member drives the limiting member to approach the second limiting stop along the first direction of the coating pinning device. This allows the second limiting stop and the limiting member connected to the sixth supporting member to jointly clamp the sheet metal assembly. Furthermore, the limiting member, the first limiting stop, and the second limiting stop cooperate to fix the sheet metal assembly, achieving the effect of fixing the position of the sheet metal assembly by the limiting mechanism. After the coating mechanism group completes coating two adjacent edges or all edges of the sheet metal assembly, the sixth supporting member drives the limiting member away from the second limiting stop, and the fifth driving member drives the limiting member to descend along the height direction of the coating pinning device. This makes the upper surface of the limiting member connected to the sixth supporting member flush with the support surface, or makes the upper surface of the limiting member connected to the sixth supporting member lower than the height of the support surface, thereby achieving the effect of unlocking the position of the sheet metal assembly by the limiting mechanism. When the pinning mechanism pins the sheet metal assembly, the seventh drive component drives the eighth support component to rise along the height direction of the overmolding pinning device, and the eighth support component drives the limiting component to approach the fourth limiting stop along the first direction of the overmolding pinning device. This causes the fourth limiting stop and the limiting component connected to the eighth support component to jointly clamp the sheet metal assembly. The limiting component, the third limiting stop, and the fourth limiting stop cooperate to fix the sheet metal assembly, achieving the effect of fixing the position of the sheet metal assembly. After the pinning mechanism completes pinning the sheet metal assembly, the eighth support component drives the limiting component away from the fourth limiting stop, and the seventh drive component drives the limiting component to descend along the height direction of the overmolding pinning device. This causes the upper surface of the limiting component connected to the eighth support component to be flush with the support surface, or the upper surface of the limiting component connected to the eighth support component to be lower than the height of the support surface, thus achieving the effect of unlocking the sheet metal assembly.

[0017] Preferably, the overmolding and pinning equipment further includes: an automatic material handling device, wherein the support surface is provided with a pre-loading area, the automatic material handling device including: a first stacking area, a second stacking area, and a third stacking area, the first stacking area being suitable for placing aluminum plates, the second stacking area being suitable for placing circuit boards, and the third stacking area being suitable for placing bakelite boards; a device body; a clamping mechanism, the clamping mechanism including a suction cup; a driving mechanism, the driving mechanism being mounted on the device body, the clamping mechanism being mounted on the driving mechanism, the driving mechanism being used to drive the clamping mechanism to move to the first stacking area, the second stacking area, or the third stacking area respectively so that the clamping mechanism clamps the aluminum plate. The automatic feeding device has a pre-loading area where the corresponding sheet material is stacked. The driving mechanism is adapted to drive the clamping mechanism to stack the sheet material sequentially in the pre-loading area. The sheet material stacked in the pre-loading area is, from top to bottom, the aluminum plate, the circuit board, and the bakelite board. The first stacking area, the second stacking area, the third stacking area, and the pre-loading area are arranged sequentially along the first direction of the automatic feeding device. The operating table forms the pre-loading area. The driving mechanism includes a first driving component and a second driving component. The first driving component is adapted to drive the clamping mechanism to move along the height direction of the automatic feeding device, and the second driving component is adapted to drive the clamping mechanism to move along the first direction.

[0018] By adopting the above technical solution, and using an automatic material handling device to automatically stack circuit boards into the pre-loading area, the labor cost of stacking circuit boards can be reduced, and the production efficiency of the overmolding and pinning equipment can be improved. Furthermore, the automatic material handling device uses suction cups to grip the circuit boards, ensuring that the clamping force on the circuit boards is uniform and gentle, minimizing the risk of bending, damage, or scratches during stacking, thereby improving the yield rate and reducing the production cost of the circuit boards.

[0019] Preferably, the overmolding and pinning equipment further includes a guiding mechanism, which includes a mounting edge and a guide wheel. The mounting edge is fixed to the edge of the operating table, and the guide wheel is mounted on the side wall of the mounting edge near the sheet metal assembly. The guide wheel is adapted to abut against the sheet metal assembly. Along the feeding direction of the sheet metal assembly, the guiding mechanism is adapted to guide the sheet metal assembly.

[0020] By adopting the above technical solution, when the worker pushes the board assembly closer to the overmolding mechanism, or when the worker pushes the board assembly away from the overmolding mechanism after the overmolding is completed, or when the worker pushes the board assembly closer to the pinning mechanism, or when the worker pushes the board assembly away from the pinning mechanism after the pinning is completed, the board assembly moves along the extension direction of the mounting edge. Furthermore, by setting guide wheels on the mounting edge, the guide wheels can guide the board assembly to prevent the board assembly from bending or breaking at the edge due to collision with the mounting edge, thereby further improving the yield of the circuit board.

[0021] Preferably, the overmolding and pinning equipment further includes a feeding device, which includes a feeding mechanism and a board collecting machine. The feeding mechanism is located on the operating table, and the board collecting machine includes an eighth driving member and a feeding platform. The feeding platform is adapted to place the board assembly. The eighth driving member is used to drive the feeding platform to rise or fall along the height direction of the overmolding and pinning equipment. The feeding mechanism is used to drive the board assembly to move from the operating table to the feeding platform.

[0022] By adopting the above technical solution, when no sheet metal assembly is placed on the feeding platform, the upper surface of the feeding platform is at the same height as the support surface of the support mechanism. After the sheet metal assembly is pinned, the operator pushes the sheet metal assembly to move it relative to the feeding mechanism. The feeding mechanism then drives the sheet metal assembly from the support surface to the feeding platform. After the sheet metal assembly is placed on the feeding platform, the eighth drive component drives the feeding platform to descend along the height direction of the overmolding and pinning equipment, so that the upper surface of the sheet metal assembly is at the same height as the support surface, thereby enabling the feeding device to continuously stack sheet metal assemblies on the feeding platform. When the operator removes the stacked sheet metal assemblies from the feeding platform, the eighth drive component resets to make the upper surface of the feeding platform at the same height as the support surface, thus enabling the feeding platform to stack the next batch of sheet metal assemblies.

[0023] Preferably, the unloading device further includes a height detection element, which is communicatively connected to the eighth drive element. The height detection element is installed on the side wall of the mounting stop away from the sheet metal group, and is used to detect the height of the sheet metal group on the unloading platform.

[0024] By adopting the above technical solution, when the height detection component detects that the height of the upper surface of the unloading platform or the upper surface of the sheet metal group is the same as or lower than the height of the support surface, the height detection component sends a trigger signal. When the eighth drive component receives the trigger signal, it stops working, thereby achieving the effect of stacking sheet metal groups in the unloading device.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By having workers push the sheet metal assembly to simultaneously engage with the first and second limiting stops, or simultaneously engage with the third and fourth limiting stops, the sheet metal assembly can be positioned before overmolding or pinning. Compared with existing technologies, for sheet metal of any radial dimension, the overmolding and pinning equipment of this application can reduce the positioning time of the sheet metal assembly, thereby improving the processing efficiency of the overmolding and pinning equipment. Furthermore, by separating the overmolding mechanism and the pinning mechanism, the structural complexity of the overmolding and pinning equipment is reduced, thereby lowering the production cost. Moreover, because the positioning method of the sheet metal assembly in this application is less difficult, the overmolding and pinning equipment has higher processing efficiency even when the sheet metal assembly is positioned multiple times. 2. When the coating mechanism is coating the sheet metal assembly, the fifth drive member drives the sixth support member to rise along the height direction of the coating pinning device, and the sixth support member drives the limiting member to approach the second limiting stop along the first direction of the coating pinning device. This causes the second limiting stop and the limiting member connected to the sixth support member to jointly clamp the sheet metal assembly. The limiting member, the first limiting stop, and the second limiting stop cooperate to fix the sheet metal assembly, achieving the effect of fixing the position of the sheet metal assembly. After the coating mechanism has finished coating two adjacent edges or all edges of the sheet metal assembly, the sixth support member drives the limiting member away from the second limiting stop, and the fifth drive member drives the limiting member to descend along the height direction of the coating pinning device. This causes the upper surface of the limiting member connected to the sixth support member to be flush with the support surface, or the upper surface of the limiting member connected to the sixth support member to be lower than the height of the support surface, thus achieving the effect of unlocking the position of the sheet metal assembly. When the pinning mechanism pins the sheet metal assembly, the seventh drive component drives the eighth support component to rise along the height direction of the overmolding pinning device, and the eighth support component drives the limiting component to approach the fourth limiting stop along the first direction of the overmolding pinning device. This causes the fourth limiting stop and the limiting component connected to the eighth support component to jointly clamp the sheet metal assembly. The limiting component, the third limiting stop, and the fourth limiting stop cooperate to fix the sheet metal assembly, achieving the effect of fixing the position of the sheet metal assembly. After the pinning mechanism completes pinning the sheet metal assembly, the eighth support component drives the limiting component away from the fourth limiting stop, and the seventh drive component drives the limiting component to descend along the height direction of the overmolding pinning device. This causes the upper surface of the limiting component connected to the eighth support component to be flush with the support surface, or the upper surface of the limiting component connected to the eighth support component to be lower than the height of the support surface, thus achieving the effect of unlocking the sheet metal assembly.

[0028] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0029] This application discloses a coating and pinning device 1000, which is used to coat and pin a board assembly. Along the thickness direction of the board assembly, the board assembly consists of an aluminum plate, at least one circuit board, and a bakelite board from top to bottom. The aluminum plate is used to dissipate heat from the board assembly, and the bakelite board is used to protect the circuit board to minimize the scratches between the circuit board and equipment such as drilling machines.

[0030] Reference Figures 1-8 According to the embodiments of this application, the overmolding and pinning equipment 1000 includes: an operating table 100, a support mechanism 200, an overmolding mechanism group 300, and a pinning mechanism 400. The upper end of the operating table 100 is a support surface 20. The edge of the operating table 100 is provided with a first limiting stop 101, a second limiting stop 102, a third limiting stop 103, and a fourth limiting stop 104. The first limiting stop 101 and the second limiting stop 102 are adjacent to each other and perpendicular to each other. The third limiting stop 103 and the fourth limiting stop 104 are adjacent to each other and perpendicular to each other. When the operator pushes the sheet metal group close to the overmolding mechanism group 300, the sheet metal group and the first limiting stop 101 and the second limiting stop 102 are both abutted and engaged, thereby realizing the positioning of the sheet metal group by the overmolding mechanism group 300 before processing the sheet metal group.

[0031] Similarly, when the worker pushes the sheet metal assembly closer to the pinning mechanism 400, the sheet metal assembly engages with both the third limit stop 103 and the fourth limit stop 104, thereby enabling the pinning mechanism 400 to position the sheet metal assembly before pinning. For example Figure 1 , Figure 2 As shown, the first limiting stop 101 and the third limiting stop 103 extend along the first direction of the overmolding and pinning equipment 1000, and the second limiting stop 102 and the fourth limiting stop 104 extend along the second direction of the overmolding and pinning equipment 1000. The first direction of the overmolding and pinning equipment 1000 can refer to... Figure 1 The front and back directions in the middle, the second direction of the overmolding and pinning equipment 1000 can refer to... Figure 1 The left and right directions in the middle.

[0032] A support mechanism 200 is disposed on the support surface 20 of the operating table 100, and the support mechanism 200 is used to support the board assembly. The support mechanism 200 can reduce the contact between the board assembly and the support surface 20, and can minimize the scratches and wear on the surface of the circuit board. When the board assembly is coated with glue, the board assembly moves along the first direction of the coating and pinning equipment 1000 on the support mechanism 200 to approach the coating mechanism group 300. The coating mechanism group 300 can coat the board assembly with glue. After the edges of the board assembly are coated, the board assembly moves along the second direction of the coating and pinning equipment 1000 on the support mechanism 200 to move away from the coating mechanism group 300.

[0033] Specifically, the coating mechanism group 300 includes a first coating mechanism 301 and a second coating mechanism 302. Both the first coating mechanism 301 and the second coating mechanism 302 are used to coat the board assembly with adhesive. The first coating mechanism 301 is located outside the first limiting edge 101, and the second coating mechanism 302 is located outside the second limiting edge 102. The first coating mechanism 301 and the second coating mechanism 302 are respectively used to wrap the corresponding edges of the board assembly with adhesive tape. When the first limiting edge 101 and the second limiting edge 102 are in contact with the board assembly, the first coating mechanism 301 and the second coating mechanism 302 simultaneously coat the two adjacent edges of the board assembly with adhesive. By cooperating with the first limiting edge 101 and the second limiting edge 102 to fix the board assembly, the movement of the board assembly can be prevented as much as possible when the coating mechanism group 300 coats the board assembly with adhesive.

[0034] Furthermore, after the first coating mechanism 301 and the second coating mechanism 302 coat the two adjacent edges of the sheet assembly, by rotating the sheet assembly 180° and then making the sheet assembly stop and cooperate with the first limiting stop 101 and the second limiting stop 102 again, the sheet assembly is repositioned. Then, the first coating mechanism 301 and the second coating mechanism 302 can coat the other two adjacent edges of the sheet assembly that are not coated. The coated sheet assembly moves away from the coating mechanism assembly 300 along the second direction on the support mechanism 200.

[0035] Along the feeding direction of the overcoating and pinning equipment 1000, the pinning mechanism 400 is located downstream of the overcoating mechanism group 300. After the board material group completes overcoating through the overcoating mechanism group 300, the pinning mechanism 400 can pin the board material group. The pinning mechanism 400 is provided with a first driving member 404, a drilling member 402, and a pinning member 401. The pinning member 401 is located outside the third limiting stop 103. The first driving member 404 is located on the operating table 100 and is connected to the pinning member 401. The first driving member 404 is used to drive the pinning member 401 to approach the board material group along the second direction of the overcoating and pinning equipment 1000.

[0036] Specifically, after the third limit stop 103 and the fourth limit stop 104 come into contact with the sheet metal assembly, the drilling part 402 approaches the sheet metal assembly along the height direction of the overmolding and pinning equipment 1000, and the height direction of the overmolding and pinning equipment 1000 points towards the sheet metal assembly. Figure 2 In the vertical direction, the drilling component 402 can drill holes in the sheet metal assembly. After the drilling component 402 completes drilling the sheet metal assembly, it moves away from the sheet metal assembly along the height direction of the overmolding and pinning device 1000. At the same time, the first driving component 404 drives the drilling component 402 to move closer to the sheet metal assembly along the second direction of the overmolding and pinning device 1000, so that the pinning component 401 can insert the pin into the drilled hole of the sheet metal assembly. After pinning, the sheet metal assembly moves away from the pinning mechanism 400 along the first direction on the support mechanism 200.

[0037] Therefore, by having the worker push the sheet assembly so that it simultaneously engages with the first limiting stop 101 and the second limiting stop 102, or simultaneously engages with the third limiting stop 103 and the fourth limiting stop 104, the sheet assembly can be positioned before overmolding or pinning. Compared with the prior art, for sheet materials of any radial size, the overmolding and pinning equipment 1000 of this application can reduce the positioning time of the sheet assembly, thereby improving the processing efficiency of the overmolding and pinning equipment 1000.

[0038] Furthermore, by separating the overmolding mechanism 300 and the pinning mechanism 400, the structural complexity of the overmolding and pinning equipment 1000 is reduced, thereby lowering its production cost. Moreover, since the positioning method for the sheet metal assembly in this application is less complex, the overmolding and pinning equipment 1000 exhibits higher processing efficiency when performing multiple positioning operations on the sheet metal assembly.

[0039] See Figure 1 , Figure 4In some embodiments of this application, the support mechanism 200 includes an air duct 201, a fan 202, and a plurality of balls 203. The fan 202 may be disposed within the air duct 201, which is disposed within the operating table 100. The air duct 201 forms a plurality of exhaust holes 204 on the support surface 20. The balls 203 are rotatably disposed in multiple rows and columns on the support surface 20, and the balls 203 are spaced apart from the exhaust holes 204. The exhaust holes 204 may be opposite to the sheet metal assembly, and the support surface 20 may be provided with ball 203 holes to avoid the balls 203. The ball 203 holes are spaced apart from the exhaust holes 204, and the balls 203 may extend part of their structure out of the support surface 20 through the ball 203 holes. During the transport of the sheet metal assembly, the fan 202 introduces air into the air duct 201, and the air is discharged from the air duct 201 through the exhaust port 204. When the exhaust port 204 is opposite to the sheet metal assembly, the air blown out by the exhaust port 204 can provide the sheet metal assembly with a supporting force away from the supporting surface 20, thereby achieving the effect of supporting the sheet metal assembly.

[0040] Meanwhile, the ball bearing 203 can support the sheet metal assembly. Through the ball bearing 203 and the sheet metal assembly's stop-and-go cooperation, the contact area between the support surface 20 and the sheet metal assembly can be reduced, thereby minimizing the risk of scratches caused by friction between the sheet metal assembly surface and the support surface 20 during the transportation of the sheet metal assembly.

[0041] See Figure 2 , Figure 5 In some embodiments of this application, the operating table 100 is further provided with a rotating component 105 and a second driving component 106. The rotating component 105 includes a drive motor 10 and a rotating platform 11. The rotating platform 11 is disposed on the support surface 20 and is adapted to be opposite to the sheet metal assembly. The rotating platform 11 can support the sheet metal assembly. The rotating platform 11 is connected to the drive motor 10 for transmission. The drive motor 10 can drive the rotating platform 11 to rotate around the central axis of the rotating platform 11. The second driving component 106 is connected and cooperates with the rotating component 105. The drive motor 10 is disposed between the rotating platform 11 and the second driving component 106. Along the height direction of the overmolding and pinning equipment 1000, the second driving component 106 is disposed below the drive motor 10. The second driving component 106 can be a motor. The second driving component 106 drives the drive motor 10 to drive the rotating platform 11 to rise or fall along the height direction of the overmolding and pinning equipment 1000, so that the rotating platform 11 stops or separates from the sheet metal assembly.

[0042] After the coating mechanism 300 coats two adjacent edges of the sheet metal assembly, the second drive unit 106 drives the drive motor 10 to raise the rotating platform 11 along the height direction of the coating pinning device 1000. The drive motor 10 also drives the sheet metal assembly to rotate 180° through the rotating platform 11, so that the coating mechanism 300 is positioned opposite to the other two adjacent edges of the sheet metal assembly. After the sheet metal assembly rotates, the second drive unit 106 drives the rotating platform 11 to descend along the height direction of the coating pinning device 1000, so that the support mechanism 200 supports the sheet metal assembly, thereby enabling the coating mechanism 300 to coat the other two adjacent edges of the sheet metal assembly.

[0043] By rotating the board assembly using the rotating component 105, the overmolding mechanism 300 can overmold all edges of the board assembly, reducing the time required to flip the assembly. Furthermore, by using the rotating platform 11 to rotate the board assembly, excessive force during manual rotation can be avoided, preventing bending and scratches on the circuit board surface caused by contact between the assembly and the support surface 20. This improves the yield rate and reduces production costs. Before the rotating platform 11 rotates the board assembly, the second drive component 106 moves the assembly away from the support surface 20 via the platform 11, further preventing scratches on the circuit board surface.

[0044] Furthermore, the rotating assembly 105 may also include a pressing mechanism 107, which is located above the operating table 100 and adapted to be opposite the sheet metal assembly. The pressing mechanism 107 can move closer to or further away from the sheet metal assembly along the overmolding and pinning equipment 1000, so that the pressing mechanism 107 presses the sheet metal assembly against the rotating platform 11. The pressing mechanism 107 includes a pressing member. Before rotating the sheet metal assembly, the second driving member 106 drives the sheet metal assembly to rise along the height direction of the overmolding and pinning equipment 1000 via the rotating platform 11. The pressing member of the pressing mechanism 107 moves closer to the rotating platform 11, so that the pressing mechanism 107 presses the sheet metal assembly against the rotating platform 11. The pressing mechanism 107 can increase the friction between the sheet metal assembly and the rotating platform 11, thereby preventing the sheet metal assembly from falling off the rotating platform 11 during rotation as much as possible. At the same time, it can allow the rotating platform 11 to more accurately adjust the rotation angle of the sheet metal assembly.

[0045] Furthermore, the rotating assembly 105 may be equipped with a first motor, which can drive the pressing mechanism 107 to rotate. When the rotating platform 11 drives the board assembly to rotate, the first motor drives the pressing mechanism 107 to rotate at the same angular velocity as the board assembly, thereby preventing the friction between the pressing mechanism 107 and the board assembly from causing the multiple circuit boards of the board assembly to rotate relative to each other when the pressing mechanism 107 presses against the board assembly.

[0046] See Figure 1 , Figure 7 In some embodiments of this application, the overmolding and pinning device 1000 further includes a limiting mechanism 500, which includes at least one limiting member 501. The limiting member 501 is vertically and flexibly disposed on the support surface 20. The limiting member 501 can be constructed as a limiting block, such as a square or wedge block. The support surface 20 is provided with a clearance opening to avoid the limiting member 501. The limiting member 501 can extend out of the support surface 20 along the height direction of the overmolding and pinning device 1000 through the clearance opening. The limiting member 501 is opposite to and spaced apart from the first limiting stop 101, and / or the limiting member 501 is opposite to and spaced apart from the second limiting stop 102, and / or the limiting member 501 is opposite to and spaced apart from the third limiting stop 103, and / or the limiting member 501 is opposite to and spaced apart from the fourth limiting stop 104.

[0047] When the worker pushes the sheet assembly closer to the coating mechanism 300, after the sheet assembly and the first limiting stop 101 and the second limiting stop 102 are both engaged, the limiting member 501 extends from below the support surface 20 and engages with the sheet assembly. The limiting member 501 and the first limiting stop 101 together clamp the sheet assembly, and / or the limiting member 501 and the second limiting stop 102 together clamp the sheet assembly. Similarly, when the worker pushes the sheet assembly closer to the support mechanism 300... When the board assembly is near the overcoating and pinning mechanism 400, after the board assembly is engaged with both the third limiting stop 103 and the fourth limiting stop 104, the limiting member 501 extends from below the support surface 20 and engages with the board assembly. The limiting member 501 and the third limiting stop 103 together clamp the board assembly, and / or the limiting member 501 and the fourth limiting stop 104 together clamp the board assembly, thereby achieving the positioning of the board assembly by the overcoating and pinning equipment 1000.

[0048] When the sheet metal assembly abuts against the first limiting edge 101 and the second limiting edge 102 and the sheet metal assembly is positioned on the overmolding and pinning equipment 1000, the first overmolding mechanism 301 and the second overmolding mechanism 302 can simultaneously overmold the corresponding edges. By cooperating with the first limiting edge 101, the second limiting edge 102 and the limiting member 501 to fix the sheet metal assembly, the sheet metal assembly can be prevented from moving as much as possible when the overmolding mechanism assembly 300 is overmolding the sheet metal assembly. After the overmolding mechanism assembly 300 has completed overmolding two adjacent edges of the sheet metal assembly, the limiting member 501 moves to below the support surface 20, thereby achieving the effect of releasing the position limit of the sheet metal assembly.

[0049] Similarly, after the sheet metal assembly abuts against the third limiting stop 103 and the fourth limiting stop 104 and the sheet metal assembly is positioned on the overmolding and pinning equipment 1000, the pinning mechanism 400 can pin the sheet metal assembly. By cooperating with the third limiting stop 103, the fourth limiting stop 104 and the limiting member 501 to fix the sheet metal assembly, the movement of the sheet metal assembly can be prevented as much as possible when the pinning mechanism 400 pins the sheet metal assembly. After the pinning mechanism 400 completes the pinning of the sheet metal assembly, the limiting member 501 moves to below the support surface 20, thereby achieving the effect of releasing the position limit of the sheet metal assembly.

[0050] In some embodiments of this application, the first limiting stop 101 may be provided with a first top support member, and the second limiting stop 102 may be provided with a second top support member. The first top support member can extend into or move out of the first limiting stop 101 and is adapted to abut against the sheet metal assembly. The second top support member can extend into or move out of the second limiting stop 102 and is adapted to abut against the sheet metal assembly. After the coating mechanism 300 completes coating two edges of the sheet metal assembly, the first support member drives the sheet metal assembly to move away from the first limiting edge 101 along the second direction of the coating and pinning device 1000. At the same time, the second support member drives the sheet metal assembly to move away from the second limiting edge 102 along the first direction of the coating and pinning device 1000. This increases the distance between the sheet metal assembly and the first limiting edge 101, and between the sheet metal assembly and the second limiting edge 102. This helps to minimize the collision between the sheet metal assembly and the first limiting edge 101 or the second limiting edge 102 during rotation, thus preventing the sheet metal assembly from colliding with the first limiting edge 101 and / or the second limiting edge 102 during rotation and causing problems with integrity or scratches.

[0051] Similarly, the third limiting stop 103 may be provided with a third top support, and the fourth limiting stop 104 may be provided with a fourth top support. The third top support can extend into or move out of the third limiting stop 103 and is adapted to abut against the sheet metal assembly. The fourth top support can extend into or move out of the fourth limiting stop 104 and is adapted to abut against the sheet metal assembly. After the pinning mechanism 400 completes the pinning of the sheet metal assembly, the third support member drives the sheet metal assembly to move away from the third limiting edge 103 along the second direction of the overmolding and pinning equipment 1000. At the same time, the fourth support member drives the sheet metal assembly to move away from the fourth limiting edge 104 along the first direction of the overmolding and pinning equipment 1000. This increases the distance between the sheet metal assembly and the third limiting edge 103, and between the sheet metal assembly and the fourth limiting edge 104. This helps to minimize the collision between the sheet metal assembly and the third limiting edge 103 or the fourth limiting edge 104 during transportation, thus preventing the sheet metal assembly from colliding with the third limiting edge 103 and / or the fourth limiting edge 104 during transportation and causing problems with its integrity or scratches.

[0052] See Figure 1 , Figure 7 In some embodiments of this application, the limiting mechanism 500 includes a fourth driving member 502 and a fifth supporting member 503. The fourth driving member 502 can be a motor, and the fifth supporting member 503 can be a cylinder. Both the fourth driving member 502 and the fifth supporting member 503 are disposed in the operating table 100 and are connected and cooperate with the limiting member 501. The fourth driving member 502 is used to drive the limiting member 501 to rise or fall along the height direction of the overmolding and pinning device 1000, so that the limiting member 501 extends out or into the operating table 100. The fourth supporting member is used to drive the limiting member 501 to approach or move away from the first limiting stop edge 101, so that the limiting member 501 stops or separates from the circuit board.

[0053] When the coating mechanism 300 coats the sheet metal assembly, the fourth drive member 502 drives the fifth support member 503 to rise along the height direction of the coating and pinning device 1000, and the fifth support member 503 drives the limiting member 501 to approach the first limiting stop 101 along the second direction of the coating and pinning device 1000, so that the first limiting stop 101 and the limiting member 501 connected to the fifth support member 503 jointly clamp the sheet metal assembly. Then, by the cooperation of the limiting member 501, the first limiting stop 101 and the second limiting stop 102, the sheet metal assembly can be fixed, and the limiting mechanism 500 can achieve the effect of fixing the position of the sheet metal assembly. After the coating mechanism 300 completes coating two adjacent edges or all edges of the sheet metal assembly, the fifth support member 503 drives the limiting member 501 away from the first coating mechanism 301, and the fourth drive member 502 drives the limiting member 501 to descend along the height direction of the coating pinning device 1000, so that the upper end surface of the limiting member 501 connected to the fifth support member 503 is flush with the support surface 20, or the upper end surface of the limiting member 501 connected to the fifth support member 503 is lower than the height position of the support surface 20, thereby achieving the effect of the limiting mechanism 500 unlocking the position of the sheet metal assembly.

[0054] See Figure 2 In some other embodiments of this application, the limiting mechanism 500 includes a fifth driving member and a sixth supporting member. The fifth driving member can be a motor, and the sixth supporting member can be a cylinder. Both the fifth driving member and the sixth supporting member are disposed within the operating table 100 and are connected and cooperate with the limiting member 501. The fifth driving member is used to drive the limiting member 501 to rise or fall along the height direction of the overmolding and pinning device 1000, so that the limiting member 501 extends out or into the operating table 100. The sixth supporting member is used to drive the limiting member 501 to move closer to or away from the second limiting stop edge 102, so that the limiting member 501 stops or separates from the circuit board.

[0055] When the coating mechanism 300 coats the sheet metal assembly, the fifth driving member drives the sixth supporting member to rise along the height direction of the coating and pinning device 1000, and the sixth supporting member drives the limiting member 501 to approach the second limiting stop 102 along the first direction of the coating and pinning device 1000, so that the second limiting stop 102 and the limiting member 501 connected to the sixth supporting member jointly clamp the sheet metal assembly. Then, the limiting member 501, the first limiting stop 101 and the second limiting stop 102 cooperate to fix the sheet metal assembly, so that the limiting mechanism 500 can fix the position of the sheet metal assembly. After the coating mechanism 300 completes coating two adjacent edges or all edges of the sheet metal assembly, the sixth top support drives the limiting member 501 away from the second limiting stop 102, and the fifth drive drives the limiting member 501 to descend along the height direction of the coating pinning device 1000, so that the upper end surface of the limiting member 501 connected to the sixth top support is flush with the support surface 20, or the upper end surface of the limiting member 501 connected to the sixth top support is lower than the height position of the support surface 20, thereby achieving the effect of the limiting mechanism 500 unlocking the position of the sheet metal assembly.

[0056] See Figure 2 In some other embodiments of this application, the limiting mechanism 500 includes a fourth driving member 502, a fifth supporting member 503, and a sixth supporting member. The limiting member 501 can be configured as two. The fourth driving member 502 and the fifth supporting member 503 are connected and cooperate with one of the limiting members 501, and the fifth driving member and the sixth supporting member are connected and cooperate with the other limiting member 501. When the coating mechanism 300 coats the sheet metal assembly, the fourth drive member 502 drives the fifth support member 503 to rise along the height direction of the coating pinning device 1000, and the fifth drive member drives the sixth support member to rise along the height direction of the coating pinning device 1000. Then, the fifth support member 503 drives the corresponding limiting member 501 to approach the first limiting stop 101 along the second direction of the coating pinning device 1000, and the fifth support member 503 drives the corresponding limiting member 501 to approach the second limiting stop 102 along the first direction of the coating pinning device 1000. Thus, the two limiting members 501, the first limiting stop 101 and the second limiting stop 102 jointly clamp the sheet metal assembly. By cooperating with the two limiting members 501, the first limiting stop 101 and the second limiting stop 102 to fix the sheet metal assembly, the effect of the limiting mechanism 500 in fixing the position of the sheet metal assembly can be further improved.

[0057] Furthermore, when the coating mechanism 300 completes coating two adjacent edges or all edges of the sheet metal assembly, the fifth support member 503 drives the corresponding limiting member 501 away from the first limiting stop 101, and the sixth support member drives the corresponding limiting member 501 away from the second limiting stop 102. The fourth drive member 502 drives the corresponding limiting member 501 to descend along the height direction of the coating pinning device 1000, and the fifth drive member drives the corresponding limiting member 501 to descend along the height direction of the coating pinning device 1000, so that the upper surfaces of the two limiting members 501 are flush with the support surface 20, or the upper surfaces of the two limiting members 501 are lower than the height position of the support surface 20, thereby achieving the effect of the limiting mechanism 500 unlocking the position of the sheet metal assembly.

[0058] See Figure 3 In some embodiments of this application, the limiting mechanism 500 includes a sixth driving member and a seventh supporting member. The sixth driving member can be a motor, and the seventh supporting member can be a cylinder. Both the sixth driving member and the seventh supporting member are disposed within the operating table 100 and are connected and cooperate with the limiting member 501. The sixth driving member is used to drive the limiting member 501 to rise or fall along the height direction of the overmolding and pinning device 1000, so that the limiting member 501 extends out or into the operating table 100. The seventh supporting member is used to drive the limiting member 501 to move closer to or away from the third limiting stop edge 103, so that the limiting member 501 stops or separates from the circuit board.

[0059] When the pinning mechanism 400 pins the sheet metal assembly, the sixth driving member drives the seventh supporting member to rise along the height direction of the overmolding pinning equipment 1000, and the seventh supporting member drives the limiting member 501 to approach the third limiting stop 103 along the second direction of the overmolding pinning equipment 1000. This causes the third limiting stop 103 and the limiting member 501 connected to the sixth supporting member to jointly clamp the sheet metal assembly. Then, the limiting member 501, the third limiting stop 103 and the fourth limiting stop 104 cooperate to fix the sheet metal assembly, thereby achieving the effect of the limiting mechanism 500 fixing the position of the sheet metal assembly. After the pinning mechanism 400 completes the pinning of the sheet metal assembly, the seventh top support drives the limiting member 501 away from the third limiting stop 103, and the sixth driving member drives the limiting member 501 to descend along the height direction of the overmolding pinning equipment 1000, so that the upper end surface of the limiting member 501 connected to the seventh top support is flush with the support surface 20, or the upper end surface of the limiting member 501 connected to the seventh top support is lower than the height position of the support surface 20, thereby achieving the effect of the limiting mechanism 500 unlocking the position of the sheet metal assembly.

[0060] See Figure 3In some other embodiments of this application, the limiting mechanism 500 includes a seventh driving member and an eighth supporting member. The seventh driving member can be a motor, and the eighth supporting member can be a cylinder. Both the seventh driving member and the eighth supporting member are disposed within the operating table 100 and are connected and cooperate with the limiting member 501. The seventh driving member is used to drive the limiting member 501 to rise or fall along the height direction of the overmolding and pinning device 1000, so that the limiting member 501 extends out or into the operating table 100. The eighth supporting member is used to drive the limiting member 501 to move closer to or away from the fourth limiting stop edge 104, so that the limiting member 501 stops or separates from the circuit board.

[0061] When the pinning mechanism 400 pins the sheet metal assembly, the seventh driving member drives the eighth supporting member to rise along the height direction of the overmolding pinning equipment 1000, and the eighth supporting member drives the limiting member 501 to approach the fourth limiting stop 104 along the first direction of the overmolding pinning equipment 1000, so that the fourth limiting stop 104 and the limiting member 501 connected to the eighth supporting member jointly clamp the sheet metal assembly. Then, the limiting member 501, the third limiting stop 103 and the fourth limiting stop 104 cooperate to fix the sheet metal assembly, so that the limiting mechanism 500 can fix the position of the sheet metal assembly. After the pinning mechanism 400 completes the pinning of the sheet metal assembly, the eighth top support drives the limiting member 501 away from the fourth limiting stop 104, and the seventh drive drives the limiting member 501 to descend along the height direction of the overmolding pinning equipment 1000, so that the upper end surface of the limiting member 501 connected to the eighth top support is flush with the support surface 20, or the upper end surface of the limiting member 501 connected to the eighth top support is lower than the height position of the support surface 20, thereby achieving the effect of the limiting mechanism 500 unlocking the position of the sheet metal assembly.

[0062] See Figure 3In some other embodiments of this application, the limiting mechanism 500 includes a sixth driving member, a seventh supporting member, and an eighth supporting member. The limiting member 501 can be configured as multiple members. The sixth driving member and the seventh supporting member are connected and cooperate with one of the limiting members 501, and the seventh driving member and the eighth supporting member are connected and cooperate with another limiting member 501. When the pinning mechanism 400 pins the sheet metal assembly, the sixth driving member drives the seventh supporting member to rise along the height direction of the overmolding pinning device 1000, and the seventh driving member drives the eighth supporting member to rise along the height direction of the overmolding pinning device 1000. Then, the seventh supporting member drives the corresponding limiting member 501 to approach the third limiting stop 103 along the second direction of the overmolding pinning device 1000, and the eighth supporting member drives the corresponding limiting member 501 to approach the fourth limiting stop 104 along the first direction of the overmolding pinning device 1000. This allows the two limiting members 501, the third limiting stop 103, and the fourth limiting stop 104 to jointly clamp the sheet metal assembly. By cooperating with the two limiting members 501, the third limiting stop 103, and the fourth limiting stop 104 to jointly fix the sheet metal assembly, the effect of the limiting mechanism 500 in fixing the position of the sheet metal assembly can be further improved.

[0063] Furthermore, when the overmolding mechanism 300 completes the pinning of the sheet metal assembly, the seventh top support drives the corresponding limiting member 501 away from the first limiting stop 101, and the eighth top support drives the corresponding limiting member 501 away from the second limiting stop 102. The sixth drive drives the corresponding limiting member 501 to descend along the height direction of the overmolding pinning device 1000, and the seventh drive drives the corresponding limiting member 501 to descend along the height direction of the overmolding pinning device 1000, so that the upper end surfaces of both limiting members 501 are flush with the support surface 20, or the upper end surfaces of both limiting members 501 are lower than the height position of the support surface 20, thereby achieving the effect of the limiting mechanism 500 unlocking the position of the sheet metal assembly.

[0064] In some embodiments of this application, the overmolding and pinning device 1000 further includes a pressure detection element and a controller. The pressure detection element, the limiting mechanism 500, the overmolding mechanism group 300, and the pressing mechanism 107 are all communicatively connected to the controller. The limiting component 501 and / or the pressing component are equipped with pressure detection elements. The pressure detection elements are used to detect the pressure value between the limiting component 501 and / or the pressing component and the board assembly. When the pressure value detected by the pressure detection element is not less than a first preset pressure value, the controller can control the limiting component 501 to stop moving according to the pressure value detected by the pressure detection element. Alternatively, when the pressure value detected by the pressure detection element is not less than a second preset pressure value, the controller can control the pressing component to stop moving according to the pressure value detected by the pressure detection element. By cooperating with the pressure detection element and the controller, excessive pressing between the limiting component 501 or the pressing component and the board assembly can be prevented as much as possible, thus preventing the board assembly from bending and further improving the yield of the circuit board. Furthermore, the controller can control the overmolding mechanism 300 to overmold the edges of the sheet metal assembly. Once the position of the sheet metal assembly is fixed, the controller can also control the overmolding mechanism 300 to perform drilling and pinning on the sheet metal assembly.

[0065] Furthermore, the overmolding and pinning equipment 1000 can also be equipped with a position sensor 303 and an infrared sensor 304. Both the position sensor 303 and the infrared sensor 304 are communicatively connected to the controller. The infrared sensor 304 is used to detect whether there is a foreign object (such as a worker's hand) inserted into the overmolding mechanism 300 or the pinning mechanism 400. When the infrared sensor 304 detects a foreign object inserted into the overmolding mechanism 300 or the pinning mechanism 400, the infrared sensor 304 sends a trigger signal. After receiving the trigger signal, the controller stops the overmolding mechanism 300 or the pinning mechanism 400 from working, thereby minimizing the risk of injury to the worker. The position sensor 303 is used to detect the position of the sheet metal assembly. When the position sensor 303 detects the sheet metal assembly at the preset processing position of the overmolding and pinning equipment 1000, the position sensor 303 sends a trigger signal. After receiving the trigger signal, the controller controls the limit mechanism 500 to position and fix the sheet metal assembly. After the sheet metal assembly is positioned and fixed, the controller controls the overmolding mechanism 300 to overmold the sheet metal assembly, or after the sheet metal assembly is positioned and fixed, the controller controls the pinning mechanism 400 to drill holes and pin the sheet metal assembly.

[0066] See Figure 1 , Figure 2In some embodiments of this application, the overmolding and pinning equipment 1000 further includes an automatic material handling device 800. The support surface 20 is provided with a pre-loading area 809. The automatic material handling device 800 includes: a drive mechanism 806, a clamping mechanism 805, a device body 804, a first stacking area 801, a second stacking area 802, and a third stacking area 803. The device body 804 provides mounting positions for each mechanism. In some embodiments, the automatic material handling device 800 may also include a storage component. The storage component has multiple stacking slots. At least one stacking slot has a first stacking area 801, at least one stacking slot has a second stacking area 802, and at least one stacking slot has a third stacking area 803. The first stacking area 801, the second stacking area 802, and the third stacking area 803 are all independent of each other, and the stacking slots can fix the position of the sheet metal. Of course, in some other embodiments, the area where the automatic material handling device 800 is located can be divided into a first material stacking area 801, a second material stacking area 802 and a third material stacking area 803.

[0067] The first stacking area 801 is suitable for placing aluminum plates, the second stacking area 802 is suitable for placing circuit boards, and the third stacking area 803 is suitable for placing bakelite boards. The first stacking area 801, the second stacking area 802, and the third stacking area 803 are spaced apart from each other to minimize the mixing of boards within these areas. Figure 1 For example, the first stacking area 801, the second stacking area 802, the third stacking area 803 and the pre-loading area 809 are arranged sequentially along the second direction of the overmolding and pinning equipment 1000, and the operating table 100 forms a pre-loading area 809.

[0068] The clamping mechanism 805 includes a suction cup 80. The driving mechanism 806 is mounted on the device body 804. The clamping mechanism 805 is mounted on the driving mechanism 806. The driving mechanism 806 includes a first driving component 807 and a second driving component 808. The driving mechanism 806 is used to drive the clamping mechanism 805 to the corresponding material stacking area to pick up materials. The first driving component 807 is adapted to drive the clamping mechanism 805 to move along the height direction of the overmolding and pinning device 1000. The second driving component 808 is adapted to drive the clamping mechanism 805 to move along the second direction of the overmolding and pinning device 1000.

[0069] Specifically, the second drive assembly 808 first drives the clamping mechanism 805 to move along the second direction of the overmolding and pinning device 1000 to above the third stacking area 803. The first drive assembly 807 then drives the clamping mechanism 805 to move downward along the height direction of the overmolding and pinning device 1000, thereby causing the suction cup 80 to clamp a bakelite board. After the suction cup 80 picks up the bakelite board, the first drive assembly 807 drives the clamping mechanism 805 to move upward along the height direction of the overmolding and pinning device 1000, causing the clamped bakelite board to move away from the third stacking area 803. After the clamping mechanism 805 rises to the initial height, the second drive component 808 drives the clamping mechanism 805 to move along the second direction of the overmolding and pinning device 1000 to above the pre-loading area. Then, the first drive component 807 drives the clamping mechanism 805 to move downward along the height direction of the overmolding and pinning device 1000. When the bakelite board contacts the plane of the pre-loading area 809, the suction cup 80 stops picking up the bakelite board and places the bakelite board in the pre-loading area 809. The first drive component 807 then drives the clamping mechanism 805 to move upward along the height direction of the overmolding and pinning device 1000 back to the initial height. In this way, the automatic picking device 800 completes the picking of the bakelite board.

[0070] Similarly, when the bakelite board is clamped into the pre-loading area 809, the clamping mechanism 805 is driven to move by the cooperation of the first drive component 807 and the second drive component 808. The clamping mechanism 805 can transfer the circuit board from the second stacking area 802 to the pre-loading area 809 in the same way. When the circuit board clamped by the clamping mechanism 805 contacts the upper surface of the bakelite board in the pre-loading area 809, the suction cup 80 stops sucking the circuit board so that the circuit board is stacked on the bakelite board. Through the cooperation of the first drive component 807 and the second drive component 808, the clamping mechanism 805 can be driven to clamp and stack the circuit board from the second stacking area 802 onto the circuit board in the pre-loading area 809 multiple times, so that the number of circuit boards in the pre-loading area 809 can reach a preset number, thereby realizing the pre-loading and stacking of circuit boards.

[0071] Furthermore, the first drive component 807 and the second drive component 808 cooperate to drive the clamping mechanism 805 to move. The clamping mechanism 805 can transfer the aluminum plate from the first stacking area 801 to the pre-loading area 809 in the same manner. When the aluminum plate clamped by the clamping mechanism 805 contacts the upper surface of the circuit board in the pre-loading area 809, the suction cup 80 stops sucking the aluminum plate so that the aluminum plate is stacked on the bakelite board. This realizes the automatic material handling device 800's material handling and stacking. At this time, the stacked materials in the pre-loading area 809 are, from top to bottom, aluminum plates, a preset number of circuit boards, and bakelite boards. It should be noted that the number of circuit boards stacked in the pre-loading area 809 is determined by the drilling performance of the drilling machine and / or the coating performance of the coating and pinning equipment 1000. Of course, in some embodiments, the user can also set the number of circuit boards stacked in the pre-loading area 809.

[0072] Therefore, by using the automatic feeding device 800 to automatically stack the circuit boards into the pre-loading area 809, the labor cost of stacking the circuit boards can be reduced, and the production efficiency of the overmolding and pinning equipment 1000 can be improved. Furthermore, the automatic feeding device 800 uses suction cups 80 to grip the circuit boards, ensuring that the clamping force on the circuit boards is uniform and gentle, minimizing the risk of bending, damage, or scratches during stacking, thereby improving the yield rate and reducing the production cost of the circuit boards.

[0073] Furthermore, the clamping mechanism 805 is also provided with a mounting base, which is installed on the first drive assembly 807. The suction cup 80 has a suction cup 80 cavity. One end of the suction cup 80 is fixedly connected to the mounting base. The end of the suction cup 80 away from the mounting base has an air inlet, which can be opposite to the sheet material. The end of the suction cup 80 near the mounting base has an air outlet. Both the air inlet and the air outlet are connected to the suction cup 80 cavity, allowing air to flow from the air inlet to the air outlet. When the clamping mechanism 805 clamps the sheet material, the suction cup 80 contacts and engages with the sheet material. By allowing the air in the gap between the air inlet and the sheet material to be discharged through the air outlet, a negative pressure can be generated at the air inlet, and the air pressure in the suction cup 80 cavity can be lower than atmospheric pressure. Under the action of air pressure, the sheet material is adsorbed by the suction cup 80, thereby achieving the technical effect of the clamping mechanism 805 clamping the sheet material.

[0074] Furthermore, the clamping mechanism 805 can be equipped with multiple suction cups 80, which are spaced apart sequentially along the circumferential direction of the mounting base. By using multiple suction cups 80, the uniformity of force on the sheet metal can be improved, preventing excessive localized force that could cause bending of the sheet metal. It also increases the clamping force of the clamping mechanism 805. Additionally, if some suction cups 80 are damaged, causing a leak in the gap between the sheet metal and the air inlet, the undamaged suction cups 80 can continue to clamp the sheet metal normally, thus improving the operational reliability of the automatic material handling device 800.

[0075] Furthermore, the automatic material handling device 800 is also equipped with a controller and a counter. The controller is communicatively connected to the drive mechanism 806 and the clamping mechanism 805. The controller can control the drive mechanism 806 and the clamping mechanism 805 to work through signals. During the process of stacking the board material into the pre-loading area 809, the controller controls the drive mechanism 806 and the clamping mechanism 805 to clamp the corresponding board material from the third stacking area 803, the second stacking area 802 and the first stacking area 801 in sequence. By controlling the drive mechanism 806 and the clamping mechanism 805 to cooperate in clamping the board material, the automatic material handling device 800 achieves the technical effect of automatically stacking the board material, reducing the labor cost of operating the automatic material handling device 800 and the time required for board material stacking, thereby improving the production efficiency of the overmolding equipment.

[0076] The counter communicates with the controller and records the number of boards picked up by the gripping mechanism 805 and placed in the pre-loading area 809. By setting the counter to record the number of boards picked up by the gripping mechanism 805 and placed in the pre-loading area 809, the accuracy of the automatic material handling device 800 is improved. Simultaneously, production personnel can adjust the number of boards picked up by the counter according to the material handling requirements, enabling the gripping mechanism 805 to pick up a preset number of aluminum plates, circuit boards, and bakelite boards respectively. It should be noted that after the gripping mechanism 805 picks up an aluminum plate and places it in the pre-loading area 809, the counter resets, clearing the recorded number of boards. This allows the counter to cyclically record the number of boards, enabling the automatic material handling device 800 to operate automatically for extended periods.

[0077] See Figure 8 In some embodiments of this application, the first drive assembly 807 includes a first motor, a transmission rod, and a motion platform. The first motor and the second drive assembly 808 are connected and cooperate. Along the height direction of the overmolding and pinning equipment 1000, the first motor is connected below the second drive assembly 808, and the transmission rod is connected between the first drive component 404 and the motion platform. The transmission rod extends along the height direction of the overmolding and pinning equipment 1000. The first motor drives the motion platform to move along the height direction of the overmolding and pinning equipment 1000 through the transmission rod. A transmission gear is provided between the first motor and the transmission rod, and the transmission rod has transmission teeth that cooperate with the transmission gear. The first motor can drive the transmission rod to move along the height direction of the overmolding and pinning equipment 1000 through the transmission gear, thereby achieving the effect of the first motor driving the motion platform to move along the height direction of the overmolding and pinning equipment 1000. Furthermore, the stroke of the transmission rod can be adjusted according to the actual production situation, thereby improving the practicality of the automatic material handling device 800.

[0078] The clamping mechanism 805 is installed on the end wall of the motion platform near the sheet metal (i.e., Figure 8The lower end wall of the motion platform), the first motor is connected to the clamping mechanism 805 for transmission. During the process of the clamping mechanism 805 clamping the material plate, the first motor can drive the motion platform through the transmission rod to drive the clamping mechanism 805 to move closer to the material plate along the height direction of the overmolding and pinning equipment 1000, so that the clamping mechanism 805 can clamp the material plate from the first stacking area 801, the second stacking area 802 or the third stacking area 803. The first motor can also drive the motion platform through the transmission rod to drive the clamping mechanism 805 to move away from the material plate along the height direction of the overmolding and pinning equipment 1000, so that the clamping mechanism 805 can move the material plate out of the first stacking area 801, the second stacking area 802 or the third stacking area 803.

[0079] When the clamping mechanism 805 transports the material board to above the pre-loading area 809, the first driving member 404 can drive the clamping mechanism 805 to approach the plane where the pre-loading area 809 is located along the height direction of the overmolding and pinning equipment 1000, so that the clamping mechanism 805 stacks the material board with the pre-loading area 809, and the first motor can drive the clamping mechanism 805 to move away from the plane where the pre-loading area 809 is located along the height direction of the overmolding and pinning equipment 1000, so that the clamping mechanism 805 moves out of the pre-loading area 809.

[0080] See Figure 8 In some embodiments of this application, the second drive assembly 808 includes a motion bracket, a second motor, and a guide rail. The second drive assembly 808 is mounted on the device body 804, wherein the guide rail is connected and cooperates with the device body 804 so that the guide rail spans above the first stacking area 801, the second stacking area 802, the third stacking area 803, and the pre-loading area 809. The guide rail extends along a first direction of the overmolding and pinning equipment 1000, and the guide rail is guided and cooperates with the motion bracket. The second motor drives the motion bracket to move along the guide rail. Specifically, the motion bracket has four guide wheels 87, and the motion bracket is connected and cooperates with the guide rail through the guide wheels 87. The second drive component 106 can be a drive motor 10, which is connected to the guide wheels 87 through a transmission connection. The power output by the drive motor 10 can make the guide wheels 87 move along the guide rail, thereby driving the motion bracket to move along the guide rail.

[0081] When the clamping mechanism 805 clamps the sheet material, the second motor drives the motion bracket to move along the guide rail, so that the clamping mechanism 805 moves directly above the first stacking area 801, the second stacking area 802, or the third stacking area 803 respectively. When the first driving member 404 drives the clamping mechanism 805 to move downward, the clamping mechanism 805 can clamp the corresponding sheet material. When the clamping mechanism 805 clamps the sheet material to the pre-loading area 809, the second driving member 106 drives the motion bracket to move along the guide rail, so that the clamping mechanism 805 moves directly above the pre-loading area 809, so that when the clamping mechanism 805 is driven by the first motor to move along the height direction of the overmolding and pinning equipment 1000, it can place the sheet material in the pre-loading area 809.

[0082] Furthermore, the second drive assembly 808 may be equipped with a transmission belt and a transmission pulley. The transmission belt is connected and cooperates with the motion support. The second motor drives the motion support to move along the guide rail by driving the transmission belt. The transmission belt and the transmission pulley have transmission teeth. The transmission teeth can prevent slippage between the transmission pulley and the transmission belt during transmission as much as possible, which can improve the accuracy of the automatic material handling device 800 during operation.

[0083] See Figure 1 , Figure 4 In some embodiments of this application, the overcoating and pinning equipment 1000 further includes a guiding mechanism 700. The guiding mechanism 700 is used to guide the sheet metal group along the feeding direction of the sheet metal group. The guiding mechanism 700 includes a mounting edge 701 and guide wheels 702. The mounting edge 701 is fixed to the edge of the operating table 100. The guide wheels 702 are mounted on the side wall of the mounting edge 701 near the sheet metal group. Multiple guide wheels 702 can be mounted on the mounting edge 701 along the feeding direction of the sheet metal group. The guide wheels 702 can make contact with the sheet metal group. When the operator pushes the sheet metal group closer to the overcoating mechanism group 300... When the board assembly is pushed away from the encapsulation mechanism 300 after the encapsulation is completed, or when the board assembly is pushed closer to the pinning mechanism 400 after the pinning is completed, or when the board assembly is pushed away from the pinning mechanism 400 after the pinning is completed, the board assembly moves along the extension direction of the mounting edge 701. The guide wheel 702 is provided on the mounting edge 701 to guide the board assembly, so as to prevent the edge of the board assembly from bending or breaking due to collision between the board assembly and the mounting edge 701, thereby further improving the yield of the circuit board.

[0084] See Figure 2In some embodiments of this application, the overmolding and pinning equipment 1000 further includes a feeding device, which includes a feeding mechanism and a board receiving machine 600. The feeding mechanism is disposed on the operating table 100, and the board receiving machine 600 includes an eighth drive member and a feeding platform 602. The feeding platform 602 is suitable for placing the board assembly. The eighth drive member is connected to the feeding platform 602 for transmission. The eighth drive member is used to drive the feeding platform 602 to rise or fall along the height direction of the overmolding and pinning equipment 1000. In some specific embodiments, the eighth drive member can be a jack. Along the feeding direction of the board assembly, the feeding device is disposed on the downstream side of the pinning machine. The overmolded and pinned circuit board can be moved away from the operating table 100 through the feeding device, thereby avoiding excessive clutter on the operating table 100.

[0085] When no sheet metal assembly is placed on the unloading platform 602, the upper surface of the unloading platform 602 is at the same height as the support surface 20 of the support mechanism 200. After the sheet metal assembly is pinned, the operator pushes the sheet metal assembly to move it to the position opposite the unloading mechanism. The unloading mechanism drives the sheet metal assembly from the support surface 20 to the unloading platform 602. The unloading mechanism can be a conveyor belt mechanism. After the sheet metal assembly is placed on the unloading platform 602, the eighth driving component drives the unloading platform 602 to descend along the height direction of the overmolding and pinning equipment 1000, so that the upper surface of the sheet metal assembly is at the same height as the support surface 20, thereby enabling the unloading device to continuously stack sheet metal assemblies on the unloading platform 602.

[0086] Furthermore, after the worker removes the stacked sheet metal groups from the unloading platform 602, the eighth drive component resets so that the upper surface of the unloading platform 602 is at the same height as the support surface 20, thereby enabling the unloading platform 602 to stack the next batch of sheet metal groups. The unloading platform 602 may be equipped with a baffle. When the unloading mechanism pushes the sheet metal group to the unloading platform 602, the baffle can limit the sheet metal group, thereby preventing the stacked sheet metal groups from shifting and detaching from the unloading platform 602 as much as possible.

[0087] In some embodiments of this application, the unloading device is equipped with a height detection element, which is communicatively connected to an eighth drive element. The height detection element is used to detect the height of the upper surface of the unloading platform 602 or the upper surface of the sheet metal group placed on the unloading platform 602. When the height detection element detects that the height of the upper surface of the unloading platform 602 or the upper surface of the sheet metal group is higher than the support surface 20, the height detection element sends a trigger signal. After receiving the trigger signal, the eighth drive element drives the unloading platform 602 to descend along the height direction of the overmolding and pinning device 1000. When the height detection element detects that the height of the upper surface of the unloading platform 602 or the upper surface of the sheet metal group is the same as or lower than the height of the support surface 20, the height detection element sends a trigger signal. When the eighth drive element receives the trigger signal, it stops working, thereby achieving the effect of stacking sheet metal groups in the unloading device.

[0088] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
