[0028] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0029] Please see Figure 1 and Figure 2 This application provides an assembly device 100 for assembling a workpiece 800 onto a product 700. The workpiece 800 can be a splitter or welded component of an electronic device such as a mobile phone, tablet computer, or laptop computer, while the product 700 can be a bottom shell or mid-frame of the same electronic device. For ease of understanding, this application uses a splitter and bottom shell of a tablet computer as examples, with the first direction defined as... Figure 1 , Figure 3 , Figure 5 and Figure 6 The X-axis direction is shown, and the second direction is... Figure 1 , Figure 3 , Figure 5 and Figure 6 The Y-axis direction shown is the third direction. Figure 1 , Figure 3 , Figure 5 and Figure 6 The Z-axis direction shown is perpendicular to each other in the first direction, the second direction, and the third direction. Obviously, this is not a limitation on the embodiments of this application.

[0030] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the assembly device 100 includes a machine base 10, a transfer mechanism 20, a vision mechanism 30, and a pressing mechanism 60.

[0031] The transfer mechanism 20 includes a moving component 21, a correction component 22, and a positioning component 23. The moving component 21 is mounted on the machine base 10. The correction component 22 and the positioning component 23 are both drivenly connected to the moving component 21. The moving component 21 drives the correction component 22 and the positioning component 23 to move along a first direction. The positioning component 23 positions the product 700. The correction component 22 includes a correction drive element 222 and a limiting unit 223. The correction drive element 222 is drivenly connected to the moving component 21, and the limiting unit 223 is drivenly connected to the correction drive element 222. The limiting unit 223 positions the workpiece 800, and the correction drive element 222 drives the limiting unit 223 to move, thereby correcting the position of the workpiece 800.

[0032] The vision mechanism 30 is located above the moving component 21. The vision mechanism 30 is used to detect the workpiece 800 and the product 700 so that the correction drive 222 can correct the position of the workpiece 800 according to the detection information of the product 700.

[0033] The pressing mechanism 60 includes a pressing component 61, which is located above the moving component 21. The pressing component 61 is used to remove the workpiece 800 from the limiting unit 223 and press the workpiece 800 onto the product 700.

[0034] When the assembly device 100 of this embodiment assembles the workpiece 800 onto the product 700, the correction component 22 and the positioning component 23 respectively position the workpiece 800 and the product 700. The moving component 21 drives the correction component 22 to move toward the vision mechanism 30. The vision mechanism 30 detects the workpiece 800 carried on the correction component 22 to determine whether the workpiece 800 is qualified. Then, the moving component 21 drives the positioning component 23 to move toward the vision mechanism 30. The vision mechanism 30 detects the product 700 carried on the positioning component 23 to determine the deviation of the area on the product 700 where the workpiece 800 is installed and whether the product 700 is qualified. The correction drive component 222 drives the limiting unit 223 to move according to the deviation of the area on the product 700 where the workpiece 800 is installed to correct the position of the workpiece 800. Then, the pressing component 61 removes the workpiece 800 from the limiting unit 223 and presses and assembles the workpiece 800 onto the product 700. Thus, the assembly device 100 of this embodiment automatically assembles the workpiece 800 onto the product 700, improving the efficiency and accuracy of assembling the workpiece 800 onto the product 700 and reducing the probability of scratching the workpiece 800 and the product 700. Furthermore, the correction drive 222 automatically corrects the position of the workpiece 800 based on the deviation of the area on the product 700 where the workpiece 800 is mounted, improving the accuracy of the pressing assembly 61 in pressing and assembling the workpiece 800 onto the product 700, thereby further improving the accuracy of assembling the workpiece 800 onto the product 700.

[0035] In this embodiment, an installation groove (not shown) is provided in the area where the workpiece 800 is installed on the product 700. Since the installation groove may be skewed during processing, the vision mechanism 30 identifies the skew of the installation groove when taking a picture of the product 700. The correction drive 222 automatically corrects the position of the workpiece 800 according to the skew of the installation groove.

[0036] In this embodiment, the moving component 21 is a linear slide table including two movers 211. The correction component 22 and the positioning component 23 are respectively disposed on the two movers 211 of the moving component 21. The two movers 211 of the moving component 21 drive the correction component 22 and the positioning component 23 to move along the first direction, so that the correction component 22 and the positioning component 23 do not interfere with each other when moving, thereby improving the efficiency of the assembly device 100 in assembling the workpiece 800 onto the product 700.

[0037] In this embodiment, there are multiple sets of transfer mechanisms 20 and pressing components 61, each corresponding to the other. Multiple sets of transfer mechanisms 20 are spaced apart along the second direction on the machine base 10, and each pressing component 61 is positioned above its corresponding moving component 21. Thus, the assembly device 100 can simultaneously assemble multiple sets of workpieces 800 onto multiple products 700, thereby improving the efficiency of assembling workpieces 800 onto products 700.

[0038] In this embodiment, the assembly device 100 further includes a feeding mechanism 40 and a picking mechanism 50. The feeding mechanism 40 is located on the machine base 10 and on the side of the vision mechanism 30 opposite to the multiple sets of pressing components 61, and is used to supply workpieces 800. The picking mechanism 50 is located on the machine base 10 and on the side of the feeding mechanism 40 facing the vision mechanism 30, and is used to sequentially pick up workpieces 800 from the feeding mechanism 40 and place them on the corresponding correction components 22. Thus, by setting the feeding mechanism 40 to automatically feed materials and the picking mechanism 50 to automatically pick up workpieces 800 from the feeding mechanism 40 and place them on the corresponding correction components 22, the efficiency of placing materials on the correction components 22 is improved, thereby improving the efficiency of the assembly device 100 in assembling workpieces 800 onto product 700.

[0039] In this embodiment, the workpiece 800 is attached to a material strip (not shown) for storage and transportation. The feeding mechanism 40 is a feeder, which carries the material roll 900 formed by the material strip and drives the material strip to move continuously to feed the material pick-up mechanism 50. In other embodiments, the feeding mechanism 40 may also use other methods such as a conveyor belt (not shown) for feeding, and this application embodiment does not specifically limit this.

[0040] In this embodiment, the assembly device 100 also includes a robot (not shown). The robot is located on one side of the machine table 10. The robot picks up the product 700 from the previous process line (not shown) and places the product 700 on the positioning component 23, thereby improving the efficiency of placing materials on the positioning component 23, and thus improving the efficiency of the assembly device 100 in assembling the workpiece 800 onto the product 700.

[0041] Please refer to the following: Figure 3 and Figure 4 In this embodiment, the correction component 22 further includes a fixed base 221, which is connected to a mover 211 of the moving component 21. The correction drive 222 is mounted on the fixed base 221 and is drivenly connected to the moving component 21 via the fixed base 221. The correction drive 222 can be a micro-motion slide, which drives the limiting unit 223 to move along a first direction and a second direction. The micro-motion slide does not require shaft compensation, saving space. Furthermore, the micro-motion slide has a small correction step and more precise movement, thereby improving the accuracy of the correction drive 222 in correcting the position of the workpiece 800 based on the skewness of the mounting slot of the product 700.

[0042] In this embodiment, the limiting unit 223 includes a support base 2231, a first pressing member 2232, and a second pressing member 2233. The support base 2231 is drivenly connected to the correction drive member 222. A correction groove 2231a is formed on the side of the support base 2231 opposite to the correction drive member 222, and the correction groove 2231a is used to receive the workpiece 800. The first pressing member 2232 is disposed on the support base 2231 and located on one side of the correction groove 2231a in a first direction. The first pressing member 2232 is used to press the workpiece 800 against the groove wall of the correction groove 2231a in the first direction. The second pressing member 2233 is disposed on the support base 2231 and located on one side of the correction groove 2231a in a second direction. The second pressing member 2233 is used to press the workpiece 800 against the groove wall of the correction groove 2231a in the second direction. In this way, the limiting unit 223 presses and positions the workpiece 800 from two mutually perpendicular directions, thereby improving the accuracy of positioning the workpiece 800.

[0043] In this embodiment, both the first extruder 2232 and the second extruder 2233 include an extrusion drive 2232a and an extrusion head 2232b. The extrusion drive 2232a can be a telescopic cylinder. The extrusion drive 2232a is disposed on the support base 2231. The extrusion head 2232b is drivenly connected to the extrusion drive 2232a. Under the drive of the extrusion drive 2232a, the extrusion head 2232b pushes the workpiece 800. Thus, the first extruder 2232 and the second extruder 2233 have simple structures and are conducive to improving the accuracy of pushing the workpiece 800.

[0044] In this embodiment, the bottom of the correction groove 2231a is provided with an adsorption hole 2231b. When the correction groove 2231a receives the workpiece 800, the adsorption hole 2231b adsorbs the workpiece 800, thereby further improving the accuracy of the positioning unit 223 in positioning the workpiece 800.

[0045] In this embodiment, each product 700 requires the assembly of multiple workpieces 800, and the shapes of these multiple workpieces 800 can be different. The feeding mechanism 40 can simultaneously supply multiple workpieces 800. There are multiple correction drive units 222 and multiple limiting units 223, with each correction drive unit 222 corresponding to one of the multiple limiting units 223. The shape of the correction groove 2231a of each limiting unit 223 is designed according to the shape of the corresponding workpiece 800. The picking mechanism 50 simultaneously picks up multiple workpieces 800 from the feeding mechanism 40 and places them into the multiple correction grooves 2231a. The vision mechanism 30 photographs the multiple mounting grooves on the product 700 and identifies the offset of the multiple mounting grooves. Each correction drive unit 222 independently corrects the position of the corresponding workpiece 800 according to the offset of the corresponding mounting groove, thereby improving the accuracy of the assembly device 100 in installing multiple workpieces 800 onto the product 700.

[0046] In this embodiment, the positioning component 23 includes a positioning seat 231, a first pushing member 232, a second pushing member 233, and a pressing member 234. The positioning seat 231 is drivenly connected to the moving component 21. The side of the positioning seat 231 opposite to the moving component 21 has a first positioning protrusion 2311a and a second positioning protrusion 2311b that are spaced apart. The first positioning protrusion 2311a is used to abut against and limit the product 700 along a first direction, and the second positioning protrusion 2311b is used to abut against and limit the product 700 along a second direction. The first pushing member 232 is disposed on the positioning seat 231 and is directly opposite to the first positioning protrusion 2311a along the first direction. The first pushing member 232 is used to press the product 700 against the first positioning protrusion 2311a along the first direction. The second pushing member 233 is disposed on the positioning seat 231 and is directly opposite to the second positioning protrusion 2311b along the second direction. The second pushing member 233 is used to press the product 700 against the second positioning protrusion 2311b along the second direction. The pressing member 234 is disposed on the positioning seat 231 and is located on one side of the first pushing member 232 and the second pushing member 233. The pressing member 234 is used to press the product 700 against the positioning seat 231 along the third direction. In this way, the positioning assembly 23 presses and positions the product 700 from three mutually perpendicular directions, thereby improving the accuracy of positioning the product 700.

[0047] In this embodiment, both the first pushing member 232 and the second pushing member 233 include a pushing drive member 2321 and a pushing head 2322. The pushing drive member 2321 can be a telescopic cylinder. The pushing drive member 2321 is located on the positioning seat 231. The pushing head 2322 is drivenly connected to the pushing drive member 2321. The pushing head 2322 pushes the product 700 under the drive of the pushing drive member 2321. Thus, the first pushing member 232 and the second pushing member 233 have simple structures and are conducive to improving the accuracy of pushing the product 700.

[0048] In this embodiment, the pressing component 234 includes a pressing drive component 2341 and a pressing head 2342. The pressing drive component 2341 can be a rotary telescopic cylinder. The pressing drive component 2341 is located on the positioning seat 231, and the pressing head 2342 is drivenly connected to the pressing drive component 2341. When the robot arm grasps the product 700 and moves it towards the positioning seat 231, the pressing drive component 2341 drives the pressing head 2342 to rotate and avoid the product 700. When the product 700 is placed on the positioning seat 231, the pressing drive component 2341 drives the pressing head 2342 to rotate above the product 700 and move towards the product 700, thereby pressing the product 700 firmly against the positioning seat 231. Thus, the pressing component 234 has a simple structure and improves the accuracy of pressing the product 700.

[0049] In this embodiment, the positioning seat 231 has a heating part 2311 on the side opposite to the moving component 21, and the first positioning protrusion 2311a and the second positioning protrusion 2311b both protrude from the heating part 2311.

[0050] Specifically, the workpiece 800 is bonded to the mounting groove of the product 700 by adhesive. The mounting groove of the product 700 was treated with adhesive in the previous process. When the pressing mechanism 60 presses the workpiece 800 onto the product 700, the heating unit 2311 heats and cures the adhesive, thereby improving the firmness of the assembly of the workpiece 800 onto the product 700.

[0051] Please refer to the following: Figure 5 In this embodiment, the vision mechanism 30 includes a first linear module 31, a second linear module 32, and an imaging element 33. The first linear module 31 is disposed above the multiple sets of moving components 21. The second linear module 32 is drivenly connected to the first linear module 31 to move along a second direction under the drive of the first linear module 31. The imaging element 33 can be a CCD camera. The imaging element 33 is drivenly connected to the second linear module 32 to move along a third direction under the drive of the second linear module 32. The imaging element 33 is used to inspect the workpiece 800 and the product 700.

[0052] When inspecting workpiece 800, the moving components 21 of the multiple sets of transfer mechanisms 20 sequentially drive the corresponding correction components 22 to move to the corresponding imaging positions. The first linear module 31 drives the second linear module 32 and the imaging element 33 to move sequentially above the multiple sets of correction components 22. The second linear module 32 drives the imaging element 33 to move toward the corresponding workpiece 800 so that the imaging element 33 can inspect the corresponding workpiece 800. When inspecting product 700, the moving components 21 of the multiple sets of transfer mechanisms 20 sequentially drive the corresponding positioning components 23 to move to the corresponding imaging positions. The first linear module 31 drives the second linear module 32 and the imaging element 33 to move sequentially above the multiple sets of positioning components 23. The second linear module 32 drives the imaging element 33 to move toward the corresponding product 700 so that the imaging element 33 can inspect the corresponding product 700. In this way, the vision mechanism 30 can inspect the workpieces 800 and products 700 carried on multiple transfer mechanisms 20 by setting up a single camera 33, saving the space required for the vision mechanism 30 and reducing costs.

[0053] Please refer to the following: Figure 6 In this embodiment, the material handling mechanism 50 includes a support frame 51, a first linear slide 52, a second linear slide 53, a connecting seat 54, a sliding member 55, a suction head 56, and a buffer member 57. The support frame 51 is mounted on the machine base 10 and located on the side of the feeding mechanism 40 facing the vision mechanism 30. The first linear slide 52 is mounted on the support frame 51. The second linear slide 53 is drivenly connected to the first linear slide 52 to move along a second direction under the drive of the first linear slide 52. The connecting seat 54 is drivenly connected to the second linear slide 53 to move along a third direction under the drive of the second linear slide 53. The sliding member 55 is slidably mounted on the connecting seat 54 along the third direction. The suction head 56 is located at one end of the sliding member 55 near the multiple sets of moving components 21, and the suction head 56 is used to pick up and place the workpiece 800. The buffer member 57 is located on the connecting seat 54 and connected to the end of the sliding member 55 away from the multiple sets of moving components 21.

[0054] When the picking mechanism 50 picks up or places workpiece 800, the first linear slide 52 drives the second linear slide 53, connecting seat 54, sliding member 55, suction head 56, and buffer member 57 to move above the feeding mechanism 40 or the corresponding correction assembly 22. The second linear slide 53 drives the connecting seat 54, sliding member 55, suction head 56, and buffer member 57 toward the feeding mechanism 40 or the corresponding correction assembly 22. The suction head 56 picks up workpiece 800 from the feeding mechanism 40 or places workpiece 800 on the correction assembly 22. The buffer member 57 provides cushioning when the suction head 56 picks up or places workpiece 800. In this way, the first linear slide 52 and the second linear slide 53 cooperate to drive the suction head 56 to pick up workpiece 800 from the feeding mechanism 40 and place it on any set of correction assemblies 22, simplifying the structure of the picking mechanism 50 and reducing its cost. In addition, by setting up the slider 55, the suction head 56 and the buffer 57, the buffer 57 provides cushioning when the suction head 56 picks up and puts in the workpiece 800, thereby reducing the probability that the suction head 56 will crush the workpiece 800, the feeding mechanism 40 and the correction component 22.

[0055] In this embodiment, the buffer 57 is a buffer cylinder. In some other embodiments, the buffer 57 may also be a hydraulic buffer. This application does not specifically limit this embodiment.

[0056] In this embodiment, the suction head 56 picks up and places the workpiece 800 by vacuum adsorption. In some other embodiments, the suction head 56 may also pick up and place the workpiece 800 by magnetic adsorption, and this application does not specifically limit this embodiment.

[0057] In this embodiment, when the material handling mechanism 50 picks up and places multiple workpieces 800 at the same time, there are multiple sliding parts 55, suction heads 56 and buffer parts 57, each corresponding to one other.

[0058] In this embodiment, the material handling mechanism 50 further includes a rotary drive 58, which can be a rotary cylinder. The rotary drive 58 is located at one end of the sliding member 55 near the multiple sets of moving components 21. The suction head 56 is driven and connected to the rotary drive 58, and the suction head 56 is connected to the sliding member 55 through the rotary drive 58. If the workpiece 800 needs to be adjusted in angle when placed on the correction component 22, the rotary drive 58 drives the suction head 56 to rotate to adjust the angle of the workpiece 800, thereby improving the accuracy of the material handling mechanism 50 in placing the workpiece 800 onto the correction component 22.

[0059] In this embodiment, the support frame 51 spans multiple sets of moving components 21, and the first linear module 31 is also mounted on the support frame 51. The first linear slide 52 and the first linear module 31 are respectively mounted on opposite sides of the support frame 51, which helps to save costs.

[0060] Please refer to the following: Figure 7 and Figure 8 In this embodiment, the pressing mechanism 60 further includes a mounting frame 62, which is disposed on the machine base 10 and located on one side of the moving component 21. The pressing component 61 includes a pressing drive 611, a moving seat 612, a guide 613, an adsorption pressing component 614, and an elastic component 615. The pressing drive 611 can be a telescopic cylinder, and the pressing drive 611 is disposed on the mounting frame 62. The moving seat 612 is drivenly connected to the pressing drive 611 so as to move closer to or away from the moving component 21 under the drive of the pressing drive 611. The guide 613 is disposed on the side of the moving seat 612 close to the moving component 21. The adsorption pressing component 614 is slidably disposed on the guide 613 along the moving direction of the moving seat 612, and the adsorption pressing component 614 is used to pick up the workpiece 800 from the limiting unit 223 and press and assemble the workpiece 800 onto the product 700 under the drive of the moving seat 612. The elastic element 615 can be a spring, and its two ends are respectively connected to the guide 613 and the end of the pressing element away from the moving assembly 21.

[0061] When the pressing mechanism 60 presses the workpiece 800 onto the product 700, the moving component 21 drives the correction component 22 to move below the pressing component 61. The pressing drive component 611 drives the suction pressing component 614 to pick up the workpiece 800 from the correction component 22. Then, the moving component 21 drives the correction component 22 to return to its original position. The moving component 21 then drives the positioning component 23 to move below the pressing component 61. The pressing drive component 611 drives the suction pressing component 614 to move towards the product 700, and the suction pressing component 614 presses the workpiece 800 into the corresponding mounting groove. During the pressing process of the workpiece 800, the elastic component 615 continuously applies pressure to the workpiece 800, thereby making the workpiece 800 and the product 700 adhere more firmly. The elastic component 615 also provides cushioning, thereby effectively reducing the probability of the suction pressing component 614 damaging the workpiece 800 and the product 700.

[0062] When the pressing mechanism 60 simultaneously presses multiple workpieces 800 into multiple mounting slots of the product 700, there are multiple guide members 613, adsorption pressing members 614, and elastic members 615, each corresponding to one other. The elastic member 615 effectively prevents interference between the multiple adsorption pressing members 614 due to different strokes when pressing the corresponding workpieces 800, and the elastic force provided by the elastic member 615 makes the pressure applied to the corresponding workpieces 800 by the multiple adsorption pressing members 614 more uniform, thereby improving the accuracy of the pressing mechanism 60 in pressing multiple workpieces 800 into the product 700.

[0063] In this embodiment, every two sets of pressing components 61 are mounted on one mounting bracket 62. Of course, in some other embodiments, each set of pressing components 61 may be mounted on a separate mounting bracket 62, or multiple sets of pressing components 61 may be mounted on a single mounting bracket 62. This application does not specifically limit this.

[0064] In this embodiment, the guide member 613 is provided with a slide rail 6131 extending in a third direction, and the adsorption pressing member 614 is slidably disposed on the slide rail 6131. ​​By setting the slide rail 6131 to control the moving direction of the adsorption pressing member 614, it is beneficial to improve the accuracy of the adsorption pressing member 614 pressing the workpiece 800 onto the product 700.

[0065] In this embodiment, the adsorption pressing member 614 has an adsorption protrusion 6141 and a limiting protrusion 6142 that are spaced apart at one end near the moving component 21. The adsorption protrusion 6141 has a magnetic part 6141a, which is used to adsorb the workpiece 800. The limiting protrusion 6142 is used to abut against the product 700 to limit the stroke of the adsorption protrusion 6141 pressing and assembling the workpiece 800 onto the product 700.

[0066] Because a magnet (not shown) is installed near the mounting slot on product 700, when the adsorption pressing member 614 presses against workpiece 800, the magnet provides an attractive force to workpiece 800, which can easily cause workpiece 800 to shift. By providing a magnetic suction part 6141a to continuously provide an attractive force to workpiece 800, the magnet installed on product 700 can be effectively prevented from causing workpiece 800 to shift, thereby improving the accuracy of pressing and installing workpiece 800 onto product 700. In addition, by providing a limiting protrusion 6142, the excessive squeezing of workpiece 800 by the adsorption pressing member 614 can be effectively prevented, thus avoiding damage to workpiece 800 and product 700.

[0067] In this embodiment, the magnetic suction part 6141a can be a magnet, and the magnetic suction part 6141a is embedded in the side of the adsorption protrusion 6141 near the moving component 21.

[0068] In this embodiment, the assembly device 100 also includes a scanning component (not shown) disposed on the machine base 10. Before the robot arm places the product 700 on the positioning component 23, it first moves the product 700 to the scanning component. The scanning component scans the identification code (not shown) on the product 700, thereby facilitating the binding of the assembly process with the information of the product 700.

[0069] In summary, the assembly device 100 of this application embodiment, by providing a transfer mechanism 20, a vision mechanism 30, and a pressing mechanism 60, and by providing a transfer mechanism 20 including a moving component 21, a correction component 22, and a positioning component 23, when the assembly device 100 assembles the workpiece 800 onto the product 700, the correction component 22 and the positioning component 23 respectively position the workpiece 800 and the product 700, the moving component 21 drives the correction component 22 and the positioning component 23 to move toward the vision mechanism 30, and the vision mechanism 30 monitors the load on the correction component 22. The assembly device 100 of this embodiment automatically assembles the workpiece 800 onto the product 700 and inspects the product 700 mounted on the positioning assembly 23 to determine whether the workpiece 800 and product 700 are qualified, and to determine the deviation of the area on the product 700 where the workpiece 800 is installed. The correction drive 222 drives the limiting unit 223 to move and correct the position of the workpiece 800 according to the deviation of the area on the product 700 where the workpiece 800 is installed. The pressing assembly 61 removes the corrected workpiece 800 from the limiting unit 223 and presses it onto the product 700. Thus, the assembly device 100 of this embodiment achieves the function of automatically assembling the workpiece 800 onto the product 700, and can accurately press and assemble the workpiece 800 onto the corresponding area of ​​the product 700 according to the deviation of the area on the product 700 where the workpiece 800 is installed, thereby improving the efficiency and accuracy of assembling the workpiece 800 onto the product 700. Furthermore, since the entire assembly process is automated, it has high stability, thereby reducing the probability of scratching or damaging the workpiece 800 and product 700.
