Technical Field

[0001] The present invention relates to the field of automation, and in particular to an automatic assembly apparatus. Background Technology

[0002] Automotive electronic controllers on the market are usually composed of a top cover, a bottom cover, and a circuit board. During the manufacturing process, the usual procedure is to first place the bottom cover on a table, then place the PCBA board inside the bottom cover, and finally place the top cover on top of the bottom cover and press it firmly to make the top cover and the bottom cover snap together.

[0003] However, the assembly of such products is mostly done manually. Due to the uncertainty of manual work and the low efficiency of manual assembly, it is not conducive to improving production efficiency, which brings inconvenience. Summary of the Invention

[0004] To address the aforementioned technical problems, embodiments of the present invention provide a user-friendly automatic assembly device.

[0005] The technical solutions adopted by the embodiments of the present invention to solve their technical problems are as follows:

[0006] An automatic assembly device includes a support platform, a moving mechanism, and an assembly mechanism. The support platform is provided with multiple contour grooves for placing workpieces to be assembled. The moving mechanism is arranged adjacent to the support platform. The assembly mechanism includes a picking module and a pressure shifting module arranged adjacent to each other. Both the picking module and the pressure shifting module are mounted on the moving mechanism and can move under the drive of the moving mechanism. The picking module is used to place the picked-up workpieces to be assembled at the assembly station, and the pressure shifting module is used to place another picked-up workpiece to be assembled at the assembly station and apply pressure to the multiple workpieces to be assembled, so that the multiple workpieces to be assembled are automatically assembled under pressure.

[0007] Optionally, the material handling module includes a telescopic component, a first cover, and a first suction cup assembly. The telescopic component is located on the moving mechanism, and the telescopic end of the telescopic component is connected to the first cover. The first suction cup assembly is located at the end of the first cover away from the telescopic component. The telescopic end of the telescopic component can drive the first cover to move synchronously to adjust the position of the first suction cup assembly. The first suction cup assembly is used to pick up the workpiece to be assembled.

[0008] Optionally, the pressure transfer module includes a connecting frame, a second suction cup group, and a pressing block. The connecting frame is connected to the moving mechanism. The second suction cup group and the pressing block are both located at one end of the connecting frame near the support platform. The second suction cup group partially penetrates the pressing block. The second suction cup group is used to pick up another workpiece to be assembled. The pressing block is used to press against multiple workpieces to be assembled when the second suction cup group places another workpiece to be assembled at the assembly station, so that the multiple workpieces to be assembled are pressed and assembled together.

[0009] Optionally, the connecting frame includes a connecting rod, a first connecting block, and a second connecting block. The two ends of the connecting rod are respectively connected to the first connecting block and the second connecting block. The first connecting block is connected to the moving mechanism. The second connecting block is provided with a second suction cup assembly and a pressing block. The pressing block is located on the side of the second connecting block away from the first connecting block. The second suction cup assembly is connected to the second connecting block and passes through the pressing block.

[0010] Optionally, the pressure shifting module further includes a sensing component and a buffer component, both of which are disposed on the connecting frame. The sensing component is used to detect the pressure of the pressure block against the workpiece to be assembled, and the buffer component is used to slow down the speed at which the connecting frame moves relative to the moving mechanism when the pressure block is against multiple workpieces to be assembled.

[0011] Optionally, the sensing component includes a pressure sensor and a transmission shaft. The pressure sensor is located at the end of the connecting frame away from the pressure block. The two ends of the transmission shaft abut against the pressure sensor and the end of the connecting frame near the pressure block, respectively. The pressure sensor is used to detect the pressure of the pressure block pressing against multiple workpieces to be assembled.

[0012] Optionally, the buffer assembly includes a protrusion, a connector, an adapter block, and an elastic element. The protrusion is fixedly connected to the moving mechanism, the adapter block is connected to the connecting frame, the protrusion has a through hole, one end of the connector is movably disposed on the protrusion, the other end of the connector passes through the through hole and is connected to the adapter block, and the elastic element is sleeved on the connector.

[0013] When the moving mechanism drives the connecting frame to press the pressing block against the workpiece to be assembled, the connecting member moves away from the pressing block along the through hole, and the elastic member will be squeezed by the adapter block.

[0014] Optionally, the pressure shifting module further includes a guide component, which is connected to both the buffer component and the moving mechanism, and is used to guide the buffer component to move in a specific direction relative to the moving mechanism.

[0015] Optionally, the automatic assembly device further includes a controller, which is connected to the moving mechanism, the material picking module, and the pressure transfer module respectively. The controller is used to control the moving mechanism to drive the assembly mechanism to move, and to control the operation of the material picking module and the pressure transfer module.

[0016] Optionally, the moving mechanism includes a lateral drive component and a vertical drive component. The lateral drive component is connected to the vertical drive component, and the vertical drive component is connected to the assembly mechanism. The lateral drive component is used to drive the vertical drive component to move along a first direction, and the vertical drive component is used to drive the assembly mechanism to move closer to or further away from the support platform along a second direction, so as to adjust the vertical distance between the assembly mechanism and the support platform, wherein the first direction is perpendicular to the second direction.

[0017] The beneficial effects of the embodiments of the present invention are as follows: The automatic assembly device provided in this application includes a support platform, a moving mechanism, and an assembly mechanism. The support platform is provided with multiple contouring grooves for placing workpieces to be assembled. The moving mechanism is arranged adjacent to the support platform. The assembly mechanism includes a picking module and a pressure shifting module arranged adjacent to each other. Both the picking module and the pressure shifting module are mounted on the moving mechanism and can move under the drive of the moving mechanism. The picking module is used to place the picked-up workpieces to be assembled at the assembly station. The pressure shifting module is used to place another picked-up workpiece at the assembly station and apply pressure to the multiple workpieces to be assembled, so that the multiple workpieces to be assembled are automatically assembled under the pressure applied by the pressure shifting module. Through the above structure, the automated assembly of multiple workpieces to be assembled can be realized, which is beneficial to improving production efficiency. Furthermore, the pressure shifting module applies pressure to the multiple workpieces to be assembled after placing them at the assembly station to complete the assembly, which is beneficial to improving the assembly effect.

[0039] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] like Figure 1-2 As shown, an automatic assembly device 1 provided in one embodiment of this application includes a support platform 2, a moving mechanism 3 and an assembly mechanism 4. The moving mechanism 3 is arranged adjacent to the support platform 2, and the assembly mechanism 4 is disposed on the moving mechanism 3. The assembly mechanism 4 is used to assemble multiple workpieces to be assembled.

[0043] The aforementioned support platform 2 is equipped with multiple contour grooves 201 for placing workpieces to be assembled, facilitating quick positioning of the workpieces by production personnel. The support platform 2 includes a base plate 21, a support plate 22, a top plate 23, and a carrier plate 24. The support plate 22 is connected to the base plate 21 and the top plate 23 at both ends. The carrier plate 24 is detachably mounted on the top plate 23 and has multiple contour grooves 201, the shape of which approximates the shape of the workpieces to be assembled. The carrier plate 24 also has multiple threaded holes 241 for connecting to the top plate 23 and multiple asymmetrically arranged positioning holes 242. These asymmetrically arranged positioning holes 242 allow for positioning of the carrier plate 24 relative to the top plate 23, facilitating quick installation of the carrier plate 24 onto the top plate 23 by production personnel. In this embodiment, there are three contouring slots 201, each corresponding to one workpiece to be assembled. The workpieces placed in the three contouring slots 201 are assembled with each other to complete the product assembly. For ease of understanding, taking an automotive controller as an example, the workpieces to be assembled corresponding to the three contouring slots 201 are a PCBA board, a bottom shell, and a top shell, respectively. During assembly, the PCBA board is first placed inside the bottom shell, and then the top shell is placed on top of the bottom shell and pressure is applied. The bottom shell and the top shell are connected to each other by snap-fit, thereby realizing the assembly of the controller.

[0044] like Figure 3As shown, the aforementioned moving mechanism 3 includes a horizontal driving component 31 and a vertical driving component 32. The horizontal driving component 31 is connected to the vertical driving component 32, and the vertical driving component 32 is connected to the assembly mechanism 4. The horizontal driving component 31 drives the vertical driving component 32 to move along a first direction X, and the vertical driving component 32 drives the assembly mechanism 4 to move closer to or further away from the support platform 2 along a second direction Z, thereby adjusting the vertical distance between the assembly mechanism 4 and the support platform 2. The first direction X and the second direction Z are perpendicular to each other. That is, the horizontal driving component 31 can drive the vertical driving component 32 to move left and right relative to the support platform 2, and the vertical driving component 32 can drive the assembly mechanism 4 to move up and down relative to the support platform 2. In this embodiment, the lateral drive assembly 31 includes a first drive motor 311, a first base 312, a first transmission assembly (not shown), and a first slider 313. The first drive motor 311, the first transmission assembly, and the first slider 313 are all mounted on the first base 312. The first drive motor 311 is connected to the first transmission assembly, the first transmission assembly is connected to the first slider 313, and the first slider 313 is connected to the vertical drive assembly 32. The first drive motor 311 drives the first slider 313 to slide along the base via the first transmission assembly, thereby adjusting the position of the vertical drive assembly 32 relative to the support platform 2. The first transmission assembly can be any power transmission mechanism, such as a worm gear structure, gear transmission structure, lead screw transmission, or others, as long as it can convert the power of the first drive motor 311 into the power for the movement of the first slider 313.

[0045] In some embodiments, such as Figure 3 As shown, the vertical drive assembly 32 includes a connecting plate 321, a second base 322, a second drive motor 323, a second transmission assembly (not shown), a second slider 324, and a mounting plate 325. The connecting plate 321 is connected to both the second base 322 and the first slider 313. The second drive motor 323, the second transmission assembly, and the second slider 324 are all mounted on the second base 322. The mounting plate 325 is connected to the second slider 324. The second drive motor 323 is connected to the second transmission assembly, and the second transmission assembly is connected to the second slider 324. The second drive motor 323 drives the second slider 324 to move through the second transmission assembly, thereby adjusting the vertical distance between the assembly mechanism 4 and the support platform 2. The second transmission assembly can be any transmission structure, as long as it can transmit the power of the second drive motor 323 to the power for the movement of the second slider 324.

[0046] like Figure 1-3As shown, the assembly mechanism 4 includes an adjacent material-picking module 41 and a pressure-shifting module 42. Both the material-picking module 41 and the pressure-shifting module 42 are mounted on the mounting plate 325. Both the material-picking module 41 and the pressure-shifting module 42 can be moved under the action of the vertical drive component 32 to adjust the vertical distance between them and the support platform 2. The material-picking module 41 is used to place the picked-up workpiece to be assembled at the assembly station. The pressure-shifting module 42 is used to place another picked-up workpiece to be assembled at the assembly station and apply pressure to multiple workpieces to be assembled, so that multiple workpieces to be assembled are automatically assembled under the pressure applied by the pressure-shifting module 42. For example, taking a car controller as an example, it typically includes a PCBA board, a bottom shell, and a top shell. During assembly, the PCBA board must first be placed inside the bottom shell, and then the top shell is placed on top of the bottom shell and pressure is applied. The buckles provided on the bottom shell and the top shell are interlocked under the pressure, thereby realizing the assembly of the product.

[0047] In some embodiments, such as Figure 1-2 As shown, the material handling module 41 includes a telescopic component 411, a first cover 412, and a first suction cup assembly 413. The telescopic component 411 is located on the moving mechanism 3, and its telescopic end is connected to the first cover 412. The first suction cup assembly 413 is located at the end of the first cover 412 away from the telescopic component 411. The telescopic end of the telescopic component 411 can drive the first cover 412 to move synchronously to adjust the position of the first suction cup assembly 413. The first suction cup assembly 413 is used to pick up the workpiece to be assembled. During operation, a negative pressure environment is provided to the first suction cup assembly 413. Under the action of the negative pressure, the first suction cup assembly 413 will pick up the workpiece to be assembled. When the material handling module 41 moves to the assembly station under the drive of the moving mechanism 3, the supply of negative pressure environment to the first suction cup assembly 413 stops. At this time, the workpiece to be assembled picked up by the first suction cup assembly 413 naturally falls into the contour groove 201 at the assembly station for further assembly.

[0048] like Figure 2 As shown, the first cover 412 includes a suction cup mounting plate 4121, a middle block 4122, and two spaced support blocks 4123. The middle block 4122 is connected to the telescopic end of the telescopic member 411. The two ends of each support block 4123 are respectively connected to the suction cup mounting plate 4121 and the middle block 4122. The suction cup mounting plate 4121 is used to install the first suction cup assembly 413, thereby constructing the first cover 412.

[0049] Understandably, the telescopic component 411 can be a structure including but not limited to a cylinder, hydraulic rod, or telescopic rod, as long as it can drive the first cover 412 to move. The first suction cup group 413 is composed of multiple suction cups and multiple connectors connected to the suction cups. The multiple connectors are used to connect to the negative pressure supply device, and the multiple suction cups are distributed in a polygonal interval to facilitate the suction of the workpiece to be assembled.

[0050] In some embodiments, such as Figure 4-5 As shown, the pressure transfer module 42 includes a connecting frame 421, a second suction cup assembly 422, and a pressing block 423. The connecting frame 421 is connected to the moving mechanism 3. The second suction cup assembly 422 and the pressing block 423 are both located at one end of the connecting frame 421 near the support platform 2, and the second suction cup assembly 422 partially penetrates the pressing block 423. The second suction cup assembly 422 is used to pick up another workpiece to be assembled, and the pressing block 423 is used to press against multiple workpieces to be assembled when the second suction cup assembly 422 places another workpiece to be assembled at the assembly station, so that the multiple workpieces to be assembled are pressed together. It can be understood that the connecting frame 421 can be directly or indirectly connected to the mounting plate 325 of the moving mechanism 3, which can be selected according to the needs. In this embodiment, the connecting frame 421 includes a connecting rod 4211, a first connecting block 4212, and a second connecting block 4213. The two ends of the connecting rod 4211 are respectively connected to the first connecting block 4212 and the second connecting block 4213. The first connecting block 4212 is connected to the mounting plate 325 of the moving mechanism 3. The second connecting block 4213 is provided with a second suction cup assembly 422 and a pressing block 423, with the pressing block 423 located on the side of the second connecting block 4213 away from the first connecting block 4212. The second suction cup assembly 422 is connected to the second connecting block 4213 and passes through the pressing block 423. There are two connecting rods 4211, spaced apart, which helps to balance the force on the first connecting block 4212 and the second connecting block 4213.

[0051] In some embodiments, such as Figure 6 As shown, the pressing block 423 has several protrusions 4231, recesses 4232, and inclined portions 4233 on the side facing the support platform 2. The protrusions 4231 are used to press against the workpiece to be assembled, the recesses 4232 are used to install the second suction cup assembly 422, and the inclined portions 4233 are used for the user to observe the state of the second suction cup assembly 422 after it picks up the workpiece, so that the second suction cup assembly 422 can make timely adjustments if the position is inaccurate after picking up the workpiece.

[0052] In some embodiments, such as Figure 5 As shown, the pressure shifting module 42 also includes a sensing component 424 and a buffer component 425. Both the sensing component 424 and the buffer component 425 are located on the connecting frame 421. The sensing component 424 is used to detect the pressure of the pressing block 423 pressing against the workpiece to be assembled. The buffer component 425 is used to slow down the speed at which the connecting frame 421 moves relative to the moving mechanism 3 when the pressing block 423 presses against multiple workpieces to be assembled.

[0053] In some embodiments, such as Figure 4As shown, the sensing assembly 424 includes a pressure sensor 4241 and a transmission shaft 4242. The pressure sensor 4241 is located on the first connecting block 4212, that is, on the end of the connecting frame 421 away from the pressing block 423. The two ends of the transmission shaft 4242 abut against the pressure sensor 4241 and the end of the connecting frame 421 near the pressing block 423, respectively. The pressure sensor 4241 is used to detect the pressure of the pressing block 423 pressing against multiple workpieces to be assembled. In this embodiment, the connecting frame 421 also includes a second cover 4214, which is connected to the second connecting block 4213 and covers the second suction cup assembly 422. The second cover 4214 abuts against the transmission shaft 4242.

[0054] Understandably, when the pressing block 423 presses against the workpiece to be assembled, the transmission shaft 4242 is subjected to the reverse force of the pressing block 423 and applies a force to the pressure sensor 4241. Thus, the force of the pressing block 423 pressing against the workpiece to be assembled can be known from the pressure received by the pressure sensor 4241. This allows the operator to adjust the descent distance of the pressure shifting module 42 according to the pressure received by the pressure sensor 4241, and avoids the assembly effect being affected by excessive pressure on multiple workpieces to be assembled.

[0055] In some embodiments, such as Figure 4 As shown, the sensing component 424 also includes a limiting structure 4243, which is connected to the mounting plate 325 and to the transmission shaft 4242. The limiting structure 4243 is used to guide and limit the transmission shaft 4242 to ensure that the transmission shaft 4242 moves along its central axis. In this embodiment, the limiting structure 4243 includes a mounting block 42431 and a bearing seat 42432. Both the mounting block 42431 and the bearing seat 42432 are located on the transmission shaft 4242. The mounting block 42431 is connected to the buffer component 425, and the bearing seat 42432 is connected to the mounting block 42431. This can constrain the movement of the transmission shaft 4242 on its central axis and reduce the risk of the transmission shaft 4242 deviating.

[0056] In some embodiments, such as Figure 4As shown, the buffer assembly 425 includes a protrusion 4251, a connector 4252, a transition block 4253, and an elastic member 4254. The protrusion 4251 is fixedly connected to the moving mechanism 3. The transition block 4253 is connected to the connecting frame 421 and to the mounting block 42431. The protrusion 4251 is provided with a through hole 42511. One end of the connector 4252 is movably disposed on the protrusion 4251. The other end of the connector 4252 passes through the through hole 42511 and is connected to the transition block 4253. The elastic member 4254 is sleeved on the connector 4252. When the moving mechanism 3 drives the connecting frame 421 to press the pressing block 423 against the workpiece to be assembled, the connecting member 4252 moves away from the pressing block 423 along the through hole 42511. The elastic member 4254 will be squeezed by the adapter block 4253, and the elastic member 4254 will apply reverse pressure to the adapter block 4253, ensuring that the pressing block 423 can normally apply pressure to the workpiece to be assembled. In this way, by compressing the elastic member 4254, the speed of the connecting frame 421 moving relative to the moving mechanism 3 is slowed down. At the same time, the connecting frame 421 gains a distance that can move relative to the mounting plate 325, reducing the risk of damage caused by the rigid collision of the connecting frame 421 with the workpiece to be assembled, which is beneficial to improving the product assembly effect of the assembly mechanism 4.

[0057] In some embodiments, such as Figure 5 As shown, the pressure shifting module 42 also includes a guide component 426, which is connected to the buffer component 425 and the moving mechanism 3 respectively. The guide component 426 is used to guide the buffer component 425 to move in a specific direction relative to the moving mechanism 3. In this embodiment, the guide component 426 includes a guide rail 4261 and a guide slider 4262. The guide slider 4262 is slidably disposed on the guide rail 4261. The guide rail 4261 is connected to the mounting plate 325, and the guide slider 4262 is connected to the adapter plate. The guide rail 4261 is arranged along the direction in which the connecting frame 421 moves relative to the mounting plate 325, which helps to ensure that the adapter plate drives the connecting frame 421 to move in a specific direction.

[0058] In some embodiments, please refer again Figure 1 The assembly mechanism 4 also includes a vacuum generator 43, which is mounted on the mounting plate 325. The vacuum generator 43 is connected to the first suction cup group 413 of the material handling module 41 and the second suction cup group 422 of the pressure transfer module 42, respectively. The vacuum generator 43 is used to provide a negative pressure environment to the first suction cup group 413 and the second suction cup group 422. Of course, in addition to using the vacuum generator 43, other structures can be used to provide a negative pressure environment to the first suction cup group 413 and the second suction cup group 422, as long as they can enable the first suction cup group 413 and the second suction cup group 422 to pick up the workpiece to be assembled.

[0059] In some embodiments, the automatic assembly device 1 further includes a controller (not shown), which is connected to the moving mechanism 3, the material picking module 41 and the pressure transfer module 42 respectively. The controller is used to control the moving mechanism 3 to drive the assembly mechanism 4 to move, and to control the material picking module 41 and the pressure transfer module 42 to work.

[0060] To facilitate understanding of the working principle of the automatic assembly device 1 of this application, the working process of the automatic assembly device 1 of this application is described below using an automobile controller as an example:

[0061] First, the workpieces to be assembled (including the PCB board, bottom shell, and top shell) are placed in the contour groove 201 on the support platform 2. This can be done manually or automatically by a robotic arm. Then, the horizontal drive component 31 drives the vertical drive component 32 and the assembly mechanism 4 to move left and right in the horizontal direction, so that the picking module 41 is positioned above the contour groove 201 of the PCB board. The telescopic end of the telescopic component 411 is extended so that the first suction cup group 413 contacts the PCB board to be assembled. Then, a negative pressure environment is provided to the first suction cup group 413 so that the first suction cup group 413 picks up the PCB board. Next, the telescopic end of the telescopic component 411 is retracted and moved to the assembly station (i.e., the position of the contour groove 201 where the bottom shell is located) under the drive of the horizontal drive component 31. At this time, the telescopic end of the telescopic component 411 is extended and the negative pressure environment is stopped from being supplied to the first suction cup group 413, so that the PCB board is accurately placed in the bottom shell, thus completing the work of the picking module 41.

[0062] Next, the telescopic end of the telescopic component 411 is retracted, and the lateral drive assembly 31 is moved so that the pressure-shifting module 42 is positioned above the workstation of the contour groove 201 where the top shell is placed. The vertical drive assembly 32 is then controlled to drive the mounting plate 325 to move, causing the pressure-shifting module 42 to descend to a preset position. The second suction cup group 422 contacts the top shell, and a negative pressure environment is provided to the second suction cup group 422. After the second suction cup group 422 picks up the top shell, it rises to a certain height to the fully positioned position. Subsequently, the lateral drive assembly 31 is controlled to move the pressure-shifting module 42 above the assembly workstation, and the vertical drive assembly 32 is controlled to lower the pressure-shifting module 42 a preset distance. Then, the supply of negative pressure environment to the second suction cup group 422 is stopped, allowing the top shell to be placed at the assembly workstation. At the same time, the pressure-shifting module 42 descends another preset distance, causing the pressing block 423 to press against the top shell and fasten it to the bottom shell, thereby completing the assembly of the automotive controller.

[0063] The automatic assembly device 1 provided in this application embodiment includes a support platform 2, a moving mechanism 3, and an assembly mechanism 4. The support platform 2 is provided with a plurality of contour grooves 201 for placing workpieces to be assembled. The moving mechanism 3 is arranged adjacent to the support platform 2. The assembly mechanism 4 includes a picking module 41 and a pressure shifting module 42 arranged adjacent to each other. Both the picking module 41 and the pressure shifting module 42 are installed on the moving mechanism 3. Both the picking module 41 and the pressure shifting module 42 can move under the drive of the moving mechanism 3. The picking module 41 is used to place the picked-up workpieces to be assembled at the assembly station. The pressure shifting module 42 is used to place another picked-up workpiece to be assembled at the assembly station and apply pressure to the plurality of workpieces to be assembled, so that the plurality of workpieces to be assembled are automatically assembled under the pressure applied by the pressure shifting module 42. The above structure enables the automated assembly of multiple workpieces to be assembled, which is beneficial to improving production efficiency. Furthermore, the pressure transfer module 42 applies pressure to multiple workpieces to be assembled after placing them at the assembly station to complete the assembly. This avoids the need for the pressure transfer module 42 to place another workpiece to be assembled at the assembly station and then apply pressure after positioning it through other structures to complete the assembly, which is beneficial to improving the assembly accuracy.
