Description

Technical Field

[0001] This disclosure relates to equipment for assembling die-cut products and metal parts, and more particularly to an automatic assembly machine for large-size die-cut parts and metal parts. Background Technology

[0002] With the continuous development and innovation of consumer electronics and the increasing integration of AI technology with traditional consumer electronics and new wearable devices, the requirements for the shape, size, and appearance of some electronic product components are becoming increasingly stringent. For the assembly of large-size die-cut parts and metal components, such as the bonding of slender die-cut films, steel sheets, and large-size foam to metal components like tablet casings, traditional production processes typically involve stamping, cleaning, manual assembly, and full inspection. However, manual assembly, especially when there are many die-cut parts, is inconvenient, requires a large workforce, is time-consuming, labor-intensive, inefficient, has low assembly precision, and is prone to deviations, product contamination, and damage, resulting in low product yield and high production costs. Summary of the Invention

[0003] The purpose of this disclosure is to provide an automatic assembly machine for large-size die-cut parts and metal parts, which can solve at least one of the above-mentioned technical problems. The technical solution of this disclosure is as follows:

[0004] An automatic assembly machine for large-size die-cut parts and metal parts includes a machine base, on which are arranged loading and unloading stations, a rotary worktable, two or more first stripping devices, picking and unloading devices corresponding to each of the first stripping devices, and first detection devices corresponding to each of the picking and unloading devices. The rotary worktable includes a first turntable, a first driving mechanism for driving the first turntable to rotate, a first fixture mounted on the first turntable, a first suction mechanism cooperating with the first fixture, and a first air passage slip ring cooperating with the first suction mechanism. The first suction mechanism can clamp and position the metal parts on the first fixture. The rotating part of the first air passage slip ring is fixedly connected to the first turntable and connected to the first suction mechanism through a pipeline. The rotation axis of the first turntable and the first air passage slip ring are the same. The picking and unloading devices can remove the die-cut parts from the first stripping devices. The first detection devices can detect the die-cut parts removed by the picking and unloading devices. The picking and unloading devices can fit and assemble the die-cut parts with the metal parts on the first fixture.

[0005] In some embodiments, the first suction mechanism includes a plurality of first suction cups, and the first fixture is provided with a first positioning groove for positioning and placing metal parts, and all the first suction cups are located in the first positioning groove.

[0006] In some embodiments, the first air passage slip ring is fixedly mounted on the machine base, and a first support is provided on the first turntable, with the first support being fixedly connected to the rotating part of the first air passage slip ring.

[0007] In some embodiments, the material handling device includes a first robotic arm with a first suction head assembly for picking up die-cut parts.

[0008] In some implementations, the first detection device is a camera detection component.

[0009] In some implementations, the bottom of the machine is equipped with casters with adjusting blocks.

[0010] In some embodiments, the first stripping device includes a first support, on which are mounted a feeding mechanism, a winding mechanism, a first pulling mechanism, a second pulling mechanism, a stripping mechanism, a pushing mechanism, and a first transition roller. The winding mechanism is located below the feeding mechanism. The feeding mechanism, the first pulling mechanism, and the stripping mechanism are arranged sequentially in a horizontal direction. The second pulling mechanism and the first transition roller are located below the stripping mechanism. The second pulling mechanism is located between the first transition roller and the winding mechanism. The stripping mechanism includes a stripping plate and equidistant rollers, with the equidistant rollers positioned below the end of the stripping plate near the first pulling mechanism. The pushing mechanism is located on one side of the stripping mechanism and can push the stripping mechanism to move back and forth in a straight line along the conveying direction of the material belt. The material belt output by the unloading mechanism can pass through the first pulling mechanism, the stripping plate, the equidistant roller, the first transition roller and the second pulling mechanism in sequence, and finally be wound up by the winding mechanism. As the die-cut parts attached to the material belt are conveyed to the designated position of the stripping plate, the first pulling mechanism and the second pulling mechanism stop pulling and press the material belt. The pick-and-place device picks up the die-cut parts on the material belt. The pushing mechanism can push the stripping mechanism to move in the direction of the first pulling mechanism so that the die-cut parts are separated from the material belt.

[0011] In some embodiments, the first material pulling mechanism includes a first material pulling roller and a first pressure roller cooperating with the first material pulling roller, the first pressure roller being located above the first material pulling roller; the second material pulling mechanism includes a second material pulling roller, a second pressure roller cooperating with the second material pulling roller, and a second drive mechanism for driving the second material pulling roller to rotate, the second pressure roller being located above the second material pulling roller.

[0012] In some embodiments, the first support is provided with a first linear slide rail that cooperates with the stripping mechanism. The pushing mechanism includes a first motor and a first synchronous belt mechanism. The first motor drives the first synchronous belt mechanism to transmit power, and the first synchronous belt mechanism drives the stripping mechanism to reciprocate linearly along the first linear slide rail.

[0013] In some embodiments, a first guide assembly is provided on the first support. The first guide assembly is located at the end of the first pulling mechanism away from the stripping mechanism. The first guide assembly includes a first support plate, on which a first suction hole and at least a pair of first stops are provided. The material strip passes through the first support plate from above the first suction hole and passes through the two opposite first stops in sequence.

[0014] The beneficial effects of this disclosure are as follows: During use, when loading at the loading / unloading station, the corresponding metal parts are first placed on the first fixture of the rotary table. The first suction mechanism clamps and positions the metal parts on the first fixture. The first drive mechanism drives the first turntable to rotate, so that the first fixture containing the metal parts corresponds to each of the first stripping devices in sequence. Each first stripping device conveys the corresponding die-cut parts. The pick-and-place device first peels off the corresponding die-cut parts from the first stripping devices. Then, the first detection device detects the die-cut parts taken out by the pick-and-place device to determine the position of the die-cut parts, etc. The pick-and-place device then attaches and assembles the die-cut parts with the metal parts on the first fixture. The die-cut parts on each of the first stripping devices are attached and assembled with the metal parts on the first fixture in sequence, and finally the process is completed. The assembled products are fed to the loading and unloading station by rotating the first turntable, thus realizing the automatic assembly of large-sized die-cut parts and metal parts. The operation is simple, convenient, and fast, with low labor intensity, effectively saving manpower and time, and high efficiency. The first suction mechanism can stably fix the metal parts on the first fixture, and the first detection device can accurately detect the position of the die-cut parts. The assembly accuracy is high, and it is not easy to cause deviations, product contamination and damage. The first air passage slip ring facilitates the arrangement of air passages and prevents air pipe entanglement caused by the rotation of the turntable, thereby improving production efficiency and product yield. It has high stability, safety and reliability, and can be better applied to the bonding and assembly of various slender die-cut films, large-sized foam and other die-cut parts and metal parts such as electronic product shells, reducing production costs.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0028] See Figures 1-7 The diagram schematically illustrates an automatic assembly machine for large-size die-cut parts and metal parts according to the present disclosure. The machine includes a base 1, on which are mounted loading / unloading stations, a rotary table 2, two or more first stripping devices 3, picking / unloading devices 4 corresponding to each of the first stripping devices 3, and first detection devices 5 corresponding to each of the picking / unloading devices 4. The rotary table 2 is used to rotate and transport the corresponding metal parts, each of the first stripping devices 3 is used to transport the corresponding die-cut parts, the picking / unloading devices 4 can remove the die-cut parts from the first stripping devices 3, the first detection devices 5 can detect the die-cut parts removed by the picking / unloading devices 4, and then assemble the removed die-cut parts with the metal parts on the rotary table 2. The number and arrangement of the first stripping device 3, the picking and unloading device 4 and the first detection device 5 are determined according to the specific situation. The loading and unloading stations and each first stripping device 3 are arranged sequentially along the circumference of the rotary worktable 2. The first stripping device 3 and the picking and unloading device 4 can be in one-to-one correspondence, and the picking and unloading device 4 and the first detection device 5 can be in one-to-one correspondence. Alternatively, one picking and unloading device 4 can correspond to two first stripping devices 3.

[0029] The rotary worktable 2 includes a first turntable 21, a first drive mechanism 22 that drives the first turntable 21 to rotate, a first fixture 23 disposed on the first turntable 21, a first suction mechanism 24 that cooperates with the first fixture 23, and a first air passage slip ring 25 that cooperates with the first suction mechanism 24. The first fixture 23 is used to position and place the corresponding metal parts, and the first suction mechanism 24 can suck and position the metal parts tightly on the first fixture 23. The number and arrangement of the first fixtures 23 depend on the specific situation. Usually, multiple first fixtures 23 are arranged along the circumference of the first turntable 21. The rotating part of the first air passage slip ring 25 is fixedly connected to the first turntable 21. The rotating part of the first air passage slip ring 25 is connected to the first suction mechanism 24 through a pipeline. The first turntable 21 and the first air passage slip ring 25 have the same rotation axis. The main body of the first air passage slip ring 25 is fixed on the machine base 1. The main body of the first air passage slip ring 25 is connected to the corresponding air supply system through an air passage. The rotating part of the first air passage slip ring 25 can rotate freely 360° relative to the main body of the first air passage slip ring 25, which facilitates the arrangement of air passages and prevents air pipe entanglement caused by the rotation of the turntable. It has high stability, safety and reliability.

[0030] During operation, the metal parts are loaded at the loading and unloading stations. First, the corresponding metal parts are placed on the first fixture 23 of the rotary table 2. The first suction mechanism 24 stably clamps and positions the metal parts on the first fixture 23. The first drive mechanism 22 drives the first turntable 21 to rotate, so that the first fixture 23 containing the metal parts sequentially aligns with each of the first stripping devices 3. Each first stripping device 3 conveys the corresponding die-cut parts. The pick-and-place device 4 first peels off and removes the corresponding die-cut parts from the first stripping device 3, and then picks and places the parts. The die-cut parts taken out by the device 4 are matched with the first detection device 5. The first detection device 5 detects the die-cut parts taken out by the material handling device 4 and accurately determines the position of the die-cut parts. The material handling device 4 then attaches and assembles the die-cut parts with the metal parts on the first fixture 23. The die-cut parts on each of the first stripping devices 3 are attached and assembled with the metal parts on the first fixture 23 in turn. Finally, the assembled products are rotated to the loading and unloading station by the first turntable 21 for unloading, thereby realizing the automatic assembly of large-size die-cut parts and metal parts.

[0031] The first drive mechanism 22 can be driven by a rotary motor, a hollow shaft motor, a hollow rotary table, a rotary cylinder, or other means to rotate the turntable. For example, a hollow rotary table can be used, where the turntable has a hollow structure and is supported by a set of precision crossed roller bearings to enable it to withstand various torques such as radial, axial, and overturning forces. The motor of the hollow rotary table is connected to the side of the turntable and can be a servo motor, stepper motor, or the like. The outer ring of the crossed roller bearing is connected to the first turntable 21. The motor of the hollow rotary table drives the outer ring of the crossed roller bearing to rotate through gear transmission, thereby driving the first turntable 21 to rotate. This method offers high efficiency, high precision, high rigidity, and stable load-bearing capacity.

[0032] The first suction mechanism 24 includes a plurality of first suction cups 241. The first fixture 23 is provided with a first positioning groove 231 for positioning and placing metal parts. All the first suction cups 241 are located in the first positioning groove 231. The number and arrangement of the first suction cups 241 are determined according to the specific situation. The structure is more compact and stable, and the stability and reliability are higher.

[0033] The first air passage slip ring 25 is fixedly installed on the machine base 1, and the first turntable 21 is provided with a first support 26. The first support 26 is fixedly connected to the rotating part of the first air passage slip ring 25, making the operation more convenient, stable and reliable.

[0034] The material handling device 4 includes a first robotic arm 41, such as a swing arm robotic arm or a six-axis robotic arm. The first robotic arm 41 is equipped with a first suction head assembly 42 for picking up die-cut parts. The first suction head assembly 42 usually includes a suction plate, and the suction plate is equipped with vacuum suction cups for picking up die-cut parts. The number and arrangement of vacuum suction cups are determined according to the specific conditions such as the length and size of the die-cut parts.

[0035] The first detection device 5 is a camera detection assembly, which is a conventional mechanism in the prior art, such as using a CCD camera for image detection. It can also be equipped with corresponding light sources, a slide table for adjusting the position of the camera detection assembly, a linear module, etc. The first detection device 5 can also use a line laser meter, a 3D scanner, a three-dimensional scanner, a three-dimensional intelligent sensor, etc.

[0036] The first stripping device 3 includes a first support 31, on which are mounted a feeding mechanism 311, a winding mechanism 312, a first pulling mechanism 32, a second pulling mechanism 33, a stripping mechanism 34, a pushing mechanism 35, and a first transition roller 313. The winding mechanism 312 is located below the feeding mechanism 311. The feeding mechanism 311, the first pulling mechanism 32, and the stripping mechanism 34 are arranged sequentially in a horizontal direction. The second pulling mechanism 33 and the first transition roller 313 are located below the stripping mechanism 34. The second pulling mechanism 33 is located between the first transition roller 313 and the first pulling mechanism 32. The stripping mechanism 34 includes a stripping plate 341 and an equidistant roller 342. The equidistant roller 342 is located below the end of the stripping plate 341 near the first pulling mechanism 32. The pushing mechanism 35 is located on one side of the stripping mechanism 34 and can push the stripping mechanism 34 to reciprocate linearly along the conveying direction of the material belt. During use, the strip with the die-cut parts attached is output by the feeding mechanism 311. Then, the strip passes sequentially through the first pulling mechanism 32, the stripping plate 341, the equidistant roller 342, the first transition roller 313, and the second pulling mechanism 33. Finally, it is wound up by the winding mechanism 312. As the die-cut parts attached to the strip are conveyed to the designated position of the stripping plate 341, the first pulling mechanism 32 and the second pulling mechanism 33 stop pulling and simultaneously press the strip together. The pick-and-place device 4 picks up the die-cut parts on the strip, and then the pushing mechanism 35 pushes the stripping mechanism 34 to move towards the first pulling mechanism 32. Since the die-cut parts held by the pick-and-place device 4 remain stationary, the die-cut parts are peeled off from the strip. Then, the pick-and-place device 4 moves the peeled die-cut parts to the position corresponding to the first detection device 5. The peeling accuracy is high, and it is more stable and reliable.

[0037] The feeding mechanism 311 and the winding mechanism 312 are conventional mechanisms in the prior art. The feeding mechanism 311 can adopt an air shaft or the like to adapt to different sizes of material rolls.

[0038] The first material pulling mechanism 32 includes a first material pulling roller 321 and a first pressure roller 322 that cooperates with the first material pulling roller 321. The first pressure roller 322 is located above the first material pulling roller 321, and the material belt passes through the space between the first pressure roller 322 and the first material pulling roller 321 for conveying. The second material pulling mechanism 33 includes a second material pulling roller 331, a second pressure roller 332 that cooperates with the second material pulling roller 331, and a second drive mechanism 333 that drives the second material pulling roller 331 to rotate. The second pressure roller 332 is located above the second material pulling roller 331, and the material belt passes through the space between the second pressure roller 332 and the second material pulling roller 331 for conveying. The second drive mechanism 333 can be an electric motor, a hydraulic motor, or other suitable power mechanism in the prior art. The second drive mechanism 333 can directly drive the second material pulling roller 331 to rotate, or it can drive the second material pulling roller 331 to rotate through a belt drive mechanism, a gear mechanism, or other transmission mechanism. The first material pulling roller 321 can also be driven to rotate by an electric motor, a hydraulic motor, or other drive mechanism.

[0039] The first support 31 is also provided with elastic adjustment components 37 that cooperate with the first pressure roller 322 and the second pressure roller 332 respectively. Elastic adjustment components 37 are provided at both ends of the first pressure roller 322 and the second pressure roller 332 respectively. The elastic adjustment components 37 enable the first pressure roller 322 to elastically cooperate with the first pulling roller 321 and the second pressure roller 332 to elastically cooperate with the second pulling roller 331, thereby facilitating the adjustment of the distance and pressure between the first pressure roller 322 and the first pulling roller 321, and facilitating the adjustment of the distance and pressure between the second pressure roller 332 and the second pulling roller 331.

[0040] See Figure 6 , Figure 7 As shown, taking the first pressure roller 322 as an example, the elastic adjustment component 37 may include a first swing arm. The shaft end of the first pressure roller 322 is provided with a first connecting shaft. One end of the first swing arm is hinged to the first bracket 31, and the other end of the first swing arm is hinged to the first connecting shaft. The first bracket 31 is provided with a fixed block, an arc-shaped groove that cooperates with the first connecting shaft, and a second adjusting screw that cooperates with the first swing arm. The second adjusting screw is threadedly connected to the fixed block. The second adjusting screw is located above the end of the first swing arm near the first connecting shaft. The second adjusting screw and the end of the first swing arm near the first connecting shaft are connected by a spring, so that the first pressure roller 322 can swing up and down relative to the first pulling roller 321 along the arc-shaped groove, thereby adjusting the distance and pressure between the first pressure roller 322 and the first pulling roller 321.

[0041] See Figure 6 , Figure 7As shown, taking the second pressure roller 332 as an example, the elastic adjustment component 37 may include a first slider connected to the shaft end of the second pressure roller 332 and a first adjusting screw located above the first slider. The first bracket 31 is provided with a slide rail that cooperates with the first slider and a fixing plate that is threadedly connected to the first adjusting screw along the vertical direction. The first adjusting screw and the first slider are cooperated by a spring. The lower end of the spring presses against the first slider, and the lower end of the first adjusting screw presses against the upper end of the spring, thereby adjusting the pressure, spacing, etc. of the second pressure roller 332 and the second pulling roller 331.

[0042] The first support 31 is provided with a first linear slide rail 314 that cooperates with the stripping mechanism 34. Typically, the first linear slide rail 314 is provided on both sides of the first support 31. A first connecting seat 343 is provided on the material feeding plate, and the first connecting seat 343 is connected to the slider of the first linear slide rail 314. The pushing mechanism 35 includes a first motor 351 and a first synchronous belt mechanism 352. The first connecting seat 343 is connected to the synchronous belt of the first synchronous belt mechanism 352 through a clamping block. The first motor 351 drives the first synchronous belt mechanism 352, which in turn drives the stripping mechanism 34 to reciprocate linearly along the first linear slide rail 314. Alternatively, the pushing mechanism 35 can also be a cylinder, hydraulic cylinder, electric cylinder, linear module, lead screw drive mechanism, etc.

[0043] A first guide assembly 36 is provided on the first support 31. The first guide assembly 36 is located at the end of the first pulling mechanism 32 away from the peeling mechanism 34. The first guide assembly 36 includes a first support plate 361, on which a first suction hole 362 and at least one pair of first stops 363 are provided. The number and arrangement of the first stops 363 are determined according to specific circumstances. During use, the material belt passes over the first suction hole 362 along the first support plate 361, and the material belt passes sequentially between two opposite first stops 363. The first stops 363 can prevent the material belt from deviating. The first suction hole 362 has a certain suction force on the material belt, so that the material belt adheres to the upper surface of the first support plate 361 for conveying, which can prevent the material belt from slack or curling up, making it safer, more stable, and more reliable. In addition, the first guide assembly 36 can also be provided between the first pulling mechanism 32 and the peeling mechanism 34.

[0044] The bottom of the machine base 1 is equipped with casters 11 with adjusting blocks, which facilitates the overall movement and leveling of the equipment, making operation convenient and improving the flexibility and stability of the equipment. The machine base 1 can be equipped with an upper housing 12, and the loading and unloading stations, the rotary worktable 2, the first stripping device 3, the material handling device 4, and the first detection device 5 are located inside the upper housing 12. The upper housing 12 is provided with clearance holes that cooperate with the loading and unloading stations and the first stripping device 3, etc. The protective cover can also be equipped with multiple layers of warning lights, safety light curtains, etc., for greater safety and reliability.

[0045] Compared with existing technologies, the advantages of this disclosure include: It enables automatic assembly of large-size die-cut parts and metal parts, such as the bonding and assembly of various slender die-cut films, die-cut small steel sheets, large-size foam, and other die-cut parts with metal parts such as electronic product casings. It is particularly suitable for situations where there are many die-cut parts requiring bonding and assembly on metal parts. The operation is simple, convenient, and fast, with low labor intensity, effectively saving manpower and time, and high efficiency. The first stop 363 of the first guide component 36 can prevent the material strip from deviating, and the first suction hole 362 has a certain suction force on the material strip, causing the material strip to adhere to the upper surface of the first support plate 361 for conveying. To prevent the material strip from loosening or warping, the first suction mechanism 24 can stably fix the metal parts in the first positioning groove 231 on the first fixture 23. The first detection device 5 can accurately detect the position of the die-cut parts before assembly. The structure is compact and stable, with high assembly accuracy, and is not prone to deviation, product contamination, or damage. The first air passage slip ring 25 facilitates the arrangement of air passages and prevents air pipe entanglement caused by the rotation of the turntable. The first stripping device 3 has high stripping accuracy and good effect, thereby improving production efficiency and product yield. It has high stability, safety, and reliability, which facilitates production control and automated production line production, and reduces production costs.
