Description

Technical Field

[0001] The present invention relates to the technical field of product assembly, and particularly to an assembly device for special-shaped circuit boards. Background Art

[0002] With the development of electronic products, the functions are increasing, and the appearance and internal structure are becoming more and more complex. During the production process, the assembly of components needs to be strictly controlled. In electronic products, there is a process of transferring a circuit board to an assembly station and installing it on a housing. Since there are multiple test points on the circuit board and subsequent connection to probes is required to test the functions of the circuit board, it is necessary to ensure the relative position between the circuit board and the housing, especially the relative position in the width direction. That is, during assembly, the relative position accuracy requirement in the width direction is higher than that in the length direction. The existing assembly process generally uses a transfer mechanism such as a manipulator to grab the circuit board and transfer it to the assembly station. To meet the relative position accuracy requirement between the circuit board and the housing in the width direction, high-precision equipment needs to be used, resulting in high costs; if equipment with lower precision is used, although it can meet the relative position accuracy requirement between the circuit board and the housing in the length direction, the relative position accuracy in the width direction is difficult to guarantee, thus affecting the yield rate and the docking between the probe and the test point, resulting in problems such as test failure and false scrapping.

[0003] Therefore, there is an urgent need to research an assembly device for special-shaped circuit boards to solve the above problems. Summary of the Invention

[0059] Before explaining any implementation manners of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements described in the following description or shown in the above drawings.

[0060] In the present application, the terms "include", "comprise", "have" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the presence of additional identical elements in the process, method, article or device including the element.

[0061] In the present application, those of ordinary skill in the art will understand that relative terms used in connection with quantities or conditions (e.g., "about", "approximately", "substantially", etc.) are intended to include the stated value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with a particular value caused by manufacturing, assembly, use, etc. Such terms should also be regarded as disclosing a range defined by the absolute values of two endpoints. Relative terms may refer to a plus or minus of a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. A numerical value without using a relative term should also be disclosed as a particular value with tolerances. In addition, when expressing a relative angular positional relationship (e.g., substantially parallel, substantially perpendicular), "substantially" may refer to a plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0062] In this application, those of ordinary skill in the art will understand that the functions performed by components can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by parts can also be performed by one part, one component, or a combination of multiple parts.

[0063] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as limiting the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that the orientation terms such as upper side, lower side, left side, right side, front side, rear side, etc. not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0064] As Figures 1 to 7 shown, this embodiment provides a special-shaped circuit board assembly device for assembling a first workpiece 1000 and a second workpiece 2000 to reduce the equipment cost and improve the yield of product assembly. Among them, the first workpiece 1000 can be a circuit board, and the second workpiece 2000 can be a housing. The special-shaped circuit board assembly device includes a base 100, a first positioning component 200, a second positioning component 300, a first driving component 400, a second driving component 500, and a picking component 600. Among them, the first positioning component 200 includes a first longitudinal positioning portion for positioning the first workpiece 1000; the second positioning component 300 includes a second longitudinal positioning portion, and the second longitudinal positioning portion is arranged at an interval from the first longitudinal positioning portion in the first direction X, and positions the second workpiece 2000 at least in the second direction Y so that in the second direction Y, the second workpiece 2000 is aligned with the first workpiece 1000; the first driving component 400 is arranged on the base 100, and its output end can move along the first direction X; the second driving component 500 is arranged at the output end of the first driving component 400, and the output end of the second driving component 500 can move along the third direction Z; the picking component 600 is arranged at the output end of the second driving component 500, and its picking end can pick up or release the first workpiece 1000. Among them, the first direction X is the left-right direction, the second direction Y is the front-rear direction, and the third direction Z is the up-down direction.

[0065] The above settings enable the first driving member 400 and the second driving member 500 to transfer the first workpiece 1000 to the second workpiece 2000 for assembly only by moving in the first direction X and the third direction Z when driving the picking component 600, avoiding the displacement of the first workpiece 1000 in the second direction Y during the installation process, thereby ensuring the relative position accuracy and the yield rate in the second direction Y after the first workpiece 1000 and the second workpiece 2000 are installed; since the installation accuracy in the first direction X and the third direction Z is lower than that in the second direction Y, therefore, the requirement for the motion accuracy of the first driving member 400 and the second driving member 500 is reduced, thereby reducing the cost of the special-shaped circuit board assembly device.

[0066] During assembly, it is necessary to first place the first workpiece 1000 on the first positioning component 200 and place the second workpiece 2000 in the second positioning component 300. To avoid interference with the picking component 600, in some embodiments, the special-shaped circuit board assembly device further includes a third driving member 700 and a carrier 710. The third driving member 700 is disposed on the base 100, and the output end of the third driving member 700 can reciprocate in the second direction Y and is connected to the carrier 710; both the first positioning component 200 and the second positioning component 300 are disposed on the carrier 710 to move synchronously along the second direction Y following the carrier 710. Among them, the third driving member 700 can move the carrier 710 backward to below the picking component 600 or forward to the front of the picking component 600. When the carrier 710 is located in front of the picking component 600, the first workpiece 1000 can be placed on the first positioning component 200 and the second workpiece 2000 can be placed in the second positioning component 300 by a manipulator without interference with the picking component 600.

[0067] Since the circuit board has a special-shaped structure, it is inconvenient to grasp with a conventional manipulator. Therefore, in some embodiments, in combination with Figure 2 and Figure 3As shown, the picking component 600 includes a picking base 610, a picking moving member 620, an elastic member 630, and a picking head 640. Among them, the picking base 610 is provided at the output end of the second driving member 500; the picking moving member 620 is movably provided on the picking base 610 along the third direction Z and can move between a lower limit position and an upper limit position; the elastic member 630 is provided between the picking base 610 and the picking moving member 620 and applies an elastic force to the picking moving member 620 to move the picking moving member 620 to the lower limit position; the picking head 640 is provided on the picking moving member 620, and the picking end is provided on the picking head 640 to pick up the top surface of the first workpiece 1000. Among them, the setting of the elastic member 630 can buffer the pressure between the picking end and the top surface of the first workpiece 1000, avoiding damage to the first workpiece 1000; in addition, it also reduces the requirement for the moving accuracy of the second driving member 500, further reducing costs. Among them, both the first driving member 400 and the second driving member 500 can be linear modules.

[0068] When picking up the first workpiece 1000, the picking head 640 needs to move downward. To avoid a large impact between the picking head 640 and the first workpiece 1000, when the picking head 640 approaches the first workpiece 1000, the moving speed of the second driving member 500 is reduced. Before contacting the first workpiece 1000, the picking head 640 is located at the lower limit position. To ensure the timing of the second driving member 500 to reduce speed, it is necessary to ensure the relative position accuracy of the picking head 640. For this reason, the picking component 600 further includes a first limiting member 650. The first limiting member 650 is connected to the picking moving member 620. When the picking moving member 620 is located at the lower limit position, the first limiting member 650 abuts against the picking base 610. Among them, the first limiting member 650 includes a threaded portion 651, a smooth rod portion 652, and a limiting head 653. The threaded portion 651 is in threaded cooperation with the threaded hole of the picking moving member 620. The picking base 610 is provided with a limiting channel extending along the third direction Z. The outer diameter of the limiting head 653 is larger than the diameter of the limiting channel. The smooth rod portion 652 is located in the limiting channel and can move relative to the picking base 610. The limiting head 653 is located at one end of the limiting channel away from the picking moving member 620. In addition, the setting of the threaded portion 651 enables the distance between the limiting head 653 and the picking moving member 620 to be adjusted, so that the lower limit position of the picking moving member 620 can be adjusted to adapt to first workpieces 1000 of different thicknesses.

[0069] To prevent relative rotation between the first limiting member 650 and the picking moving member 620, resulting in their separation, in some embodiments, the picking component 600 further includes a second limiting member 660. The second limiting member 660 is connected between the picking moving member 620 and the first limiting member 650 to lock the picking moving member 620 and the first limiting member 650.

[0070] Exemplarily, the second limiting member 660 has a connecting channel. The side wall of the connecting channel has threads, and the connecting channel is in threaded cooperation with the threaded portion 651. The bottom end of the second limiting member 660 abuts against the picking moving member 620, and the top end of the second limiting member 660 can abut against the picking seat 610 to limit the upper limit position of the picking moving member 620. This setting can not only lock the first limiting member 650 and the picking moving member 620, but also move synchronously with the picking moving member 620 to limit the upper limit position of the picking moving member 620. The second limiting member 660 is located below the limiting channel. Among them, the second limiting member 660 can be a nut or a threaded sleeve.

[0071] The picking assembly 600 further includes a guide rod 670. The picking seat 610 is provided with a guide channel. The guide rod 670 is connected to the picking moving member 620 and is slidably disposed in the guide channel. The elastic member 630 is a spring. The spring is sleeved on the guide rod 670, and both ends respectively abut against the picking seat 610 and the picking moving member 620. On the one hand, the guide rod 670 can provide guidance for the picking moving member 620, which helps to ensure the moving trajectory of the picking moving member 620; on the other hand, it can also provide an installation position for the spring to avoid flying and ensure the reliability of the spring during use. In this embodiment, the setting of the threaded portion 651 enables the distance between the limiting head 653 and the picking moving member 620 to be adjustable, so that the lower limit position of the picking moving member 620 is adjustable to adjust the elastic force of the spring.

[0072] Among them, the picking seat 610 includes a picking bottom plate 611 and a picking limiting block 612. The picking limiting block 612 is disposed on the picking bottom plate 611; the limiting channel and the guide channel are both disposed on the picking limiting block 612. The upper end of the elastic member 630 abuts against the picking limiting block 612. When the second picking moving member 620 is at the upper limit position, the upper end of the second limiting member 660 abuts against the picking limiting block 612. When the second picking moving member 620 is at the upper limit position, the spring is compressed, and the height of the spring after ultimate compression is the first dimension, and the height of the second limiting member 660 is the second dimension. The second dimension is greater than the first dimension to avoid damage to the spring.

[0073] There are two guide rods 670 and springs respectively. Correspondingly, there are two guide channels. The limiting channel is located between the two guide channels. The picking bottom plate 611 is provided with a slide rail 613, and the picking moving member 620 is installed with a slider 614. The slider 614 is slidably disposed on the slide rail 613.

[0074] In other embodiments, the second limiting member 660 can be a strip-shaped key. The threaded portion 651 is provided with a first key groove, and the picking moving member 620 is provided with a second key groove. The first key groove and the second key groove can form a limiting groove, and the key can be inserted into the limiting groove. The lower end of the key abuts against the bottom of the limiting groove. When the picking moving member 620 moves to the upper limit position, the top end of the key can abut against the picking limiting block 612.

[0075] The first keyway and / or the second keyway are provided with several. As the threaded portion 651 rotates, several limiting grooves can be formed to improve the adjustment accuracy of the first limiting member 650. In some embodiments, several first keyways are provided. At different rotation angles of the threaded portion 651, several first keyways and one second keyway form several limiting grooves. Similarly, in some embodiments, several second keyways are provided, and several limiting grooves can also be formed. In some embodiments, several first keyways and several second keyways are provided respectively, and several limiting grooves are formed during the rotation of the threaded portion 651.

[0076] In some embodiments, the picking component 600 further includes several suction heads 680. The several suction heads 680 are dispersedly arranged on the picking head 640 and are used to adsorb the first workpiece 1000 simultaneously. When the first workpiece 1000 is other parts and can be attracted by a magnet, the suction heads 680 can be replaced by magnets. Regarding the installation of the suction heads 680, in some embodiments, as shown in Figure 5 the picking component 600 further includes a pressing plate 642. The picking head 640 has a picking groove, gas holes communicating with the picking groove, and several mounting holes. The pressing plate 642 is hermetically covered at the notch of the picking groove and encloses a picking cavity 641. The several suction heads 680 are respectively installed in the several mounting holes, and one end of the suction head 680 communicates with the picking cavity 641, and the other end communicates with the outside. The gas holes can communicate with an external vacuum device. The four mounting holes are arranged in a 2×2 matrix or are reasonably arranged locally according to the structure of the first workpiece 1000.

[0077] To ensure that the picking head 640 can accurately pick up the first workpiece 1000, in some embodiments, the picking component 600 further includes at least two positioning pins 690. The at least two positioning pins 690 are spaced apart on the picking head 640 and can be correspondingly inserted and matched with at least two positioning holes on the first positioning component 200. Among them, the positioning pins 690 are made of plastic or metal.

[0078] During the production process, scratches or bends and other damages are likely to occur to the first workpiece 1000 during the transfer process. Therefore, the first positioning assembly 200 includes a first carrier 210 for carrying the first workpiece 1000. Among them, the first positioning assembly 200 further includes a first longitudinal positioning block 220. A first longitudinal positioning portion is formed on one side wall of the first longitudinal positioning block 220 along the second direction Y, and one side wall of the first carrier 210 along the second direction Y can abut against the first longitudinal positioning portion. The first positioning assembly 200 further includes a first transverse positioning block 230. A first transverse positioning portion is formed on one side wall of the first transverse positioning block 230 along the first direction X, and one side wall of the first carrier 210 along the first direction X can abut against the first transverse positioning portion. The arrangement of the first carrier 210 can ensure the safety of the first workpiece 1000 during the transfer between each working station. At the same time, the arrangements of the first longitudinal positioning block 220 and the first transverse positioning block 230 can limit the first carrier 210 in the horizontal direction, thereby ensuring the specific position of the first workpiece 1000 in the horizontal direction and facilitating it to be picked up by the pick-up head 640. In this embodiment, the positioning holes are provided on the first carrier 210.

[0079] The first positioning assembly 200 further includes a magnetic attraction member. The magnetic attraction member is provided on the first longitudinal positioning block 220 to attract the first carrier 210. The magnetic attraction member is provided on the first transverse positioning block 230 to attract the first carrier 210, so that the first carrier 210 is attracted and fixed, thereby preventing the relative position between the first carrier 210 and the carrier 710 from shifting due to the vibration generated during the assembly process. The magnetic attraction member is a permanent magnet.

[0080] After the first workpiece 1000 is taken from the first carrier 210, it is necessary to move the first carrier 210 out of the carrier 710 to replace the next first carrier 210 with the first workpiece 1000. To improve the convenience of the first carrier 210, in some embodiments, the first positioning assembly 200 further includes a discharging member 240. The first longitudinal positioning block 220 is provided with a longitudinal channel extending in the second direction Y. The discharging member 240 is disposed on the first longitudinal positioning block 220. The output end of the discharging member 240 can reciprocate in the second direction Y. The output end of the discharging member 240 can extend out of the longitudinal channel and push against the first carrier 210 to make the first carrier 210 overcome the magnetic force and move away from the first longitudinal positioning block 220. The output end of the discharging member 240 can also be hidden in the longitudinal channel to facilitate the first carrier 210 to fit against the first longitudinal positioning block 220. The discharging member 240 is a cylinder, and the output end of the cylinder is provided with a push rod, and the push rod is slidably disposed in the longitudinal channel. Wherein, in the second direction Y, the distance between the magnetic attracting member on the first transverse positioning block 230 and the first longitudinal positioning portion is the first length, and the length of the output end of the discharging member 240 extending out of the longitudinal channel is the second length, and the second length is greater than the first length. The above size limitation enables a discharging member 240 to help the first carrier 210 overcome the magnetic forces in two directions, thus easily completing the disassembly of the first carrier 210.

[0081] It should be noted that detection members 250 are provided on both the first longitudinal positioning block 220 and the first transverse positioning block 230 to detect two mutually perpendicular side walls of the first carrier 210, so as to ensure that the first carrier 210 is located on the carrier 710 and the two sides are respectively attached to the first longitudinal positioning block 220 and the first transverse positioning block 230.

[0082] To avoid damage to the second workpiece 2000 during transfer, in some embodiments, the second positioning component 300 includes a second carrier 310 for carrying the second workpiece 2000. The second positioning component 300 further includes a second longitudinal positioning block 320. A second longitudinal positioning portion is formed on one side wall of the second longitudinal positioning block 320 along the second direction Y, and one side wall of the second carrier 310 along the second direction Y can abut against the second longitudinal positioning portion. The second positioning component 300 further includes a second transverse positioning block 330. A second transverse positioning portion is formed on one side wall of the second transverse positioning block 330 along the first direction X, and one side wall of the second carrier 310 along the first direction X can abut against the second transverse positioning portion. At the same time, the second longitudinal positioning block 320 and the second transverse positioning block 330 can limit the second carrier 310 in the horizontal direction, thereby ensuring the specific position of the second workpiece 2000 in the horizontal direction and facilitating the cooperation with the first workpiece 1000. A magnetic member is provided on the second longitudinal positioning block 320 to adsorb the second carrier 310. A magnetic member is provided on the second transverse positioning block 330 to adsorb the second carrier 310. Wherein, a discharging member 240 is also provided on the second longitudinal positioning block 320 to separate the second carrier 310 from the second longitudinal positioning block 320 and at the same time separate the magnetic members on the second carrier 310 and the second transverse positioning block 330.

[0083] In some embodiments, the first transverse positioning block 230 and the second transverse positioning block 330 are arranged at intervals along the first direction X, and the first carrier 210 and the second carrier 310 are located between the first transverse positioning block 230 and the second transverse positioning block 330. The above position layout can provide a large installation space for the placement of the first carrier 210 and the second carrier 310. Additionally, after the sizes of the first carrier 210 and the second carrier 310 change accordingly, they can still be positioned by the first transverse positioning block 230 and the second transverse positioning block 330. Exemplarily, along the first direction X, when the size of the first carrier 210 increases and the size of the second carrier 310 decreases, as long as the overall size of the two carriers is smaller than the distance between the first transverse positioning block 230 and the second transverse positioning block 330, they can be placed between the first transverse positioning block 230 and the second transverse positioning block 330.

[0084] Combined with Figure 6 and Figure 7As shown in the figure, the second vehicle 310 includes a carrier plate 311, a linkage assembly, a longitudinal movable block 312, and a transverse movable block 313. A longitudinal stopper 3111 and a transverse stopper 3112 are provided on the carrier plate 311. The longitudinal movable block 312 is slidably disposed on the carrier plate 311 along the second direction Y and can approach or move away from the longitudinal stopper 3111. The transverse movable block 313 is slidably disposed on the carrier plate 311 along the first direction X and can approach or move away from the transverse stopper 3112. The linkage assembly is disposed on the carrier plate 311 and is used to drive the longitudinal movable block 312 and the transverse movable block 313 to move synchronously.

[0085] The linkage assembly includes a cam rod 314, a longitudinal connecting rod 315, and a transverse connecting rod 316. The cam rod 314 is rotatably disposed on the carrier plate 311. The longitudinal connecting rod 315 is slidably disposed on the carrier plate 311 along the first direction X, and one end thereof abuts against the outer periphery of the cam rod 314. The longitudinal connecting rod 315 has a first inclined surface 3151, and the first inclined surface 3151 is inclined with respect to the longitudinal stopper 3111 in a direction away from the cam rod 314. The longitudinal movable block 312 has a second inclined surface 3121 that is parallel to and abuts against the first inclined surface 3151. When the cam rod 314 rotates, it can drive the longitudinal connecting rod 315 to move and drive the longitudinal movable block 312 away from the longitudinal stopper 3111. The transverse connecting rod 316 is slidably disposed on the carrier plate 311 along the first direction X, one end thereof abuts against the outer periphery of the cam rod 314, and the other end is connected to the transverse movable block 313. When the cam rod 314 rotates, it can drive the transverse connecting rod 316 to move and drive the transverse movable block 313 away from the transverse stopper 3112.

[0086] Wherein, the cam rod 314 includes two spaced-apart circular rod portions 3141 and a cam portion 3142 disposed between the two circular rod portions 3141. The radial cross-section of the cam portion 3142 is non-circular. The longitudinal connecting rod 315 and the transverse connecting rod 316 both abut against the cam portion 3142, and the circular rod portions 3141 are rotatably disposed on the carrier plate 311. Further, one end of the longitudinal connecting rod 315 that abuts against the cam rod 314 is hemispherical; one end of the transverse connecting rod 316 that abuts against the cam rod 314 is hemispherical. A handle 317 is provided at the end of the cam rod 314 to facilitate turning the cam rod 314.

[0087] A longitudinal elastic member 630 is disposed between the longitudinal movable block 312 and the carrier plate 311 and is used to drive the longitudinal movable block 312 to approach the longitudinal stopper 3111; a transverse elastic member 630 is disposed between the transverse movable block 313 and the carrier plate 311 and is used to drive the transverse movable block 313 to approach the transverse stopper 3112.
