Description

Technical Field

[0001] This utility model relates to the field of product assembly technology, and in particular to an assembly equipment for irregularly shaped circuit boards. Background Technology

[0002] With the development of electronic products, their functions are becoming increasingly diverse, and their appearance and internal structure are becoming more complex. Strict control over component assembly is required during production. Electronic products involve the process of transferring circuit boards to assembly stations and mounting them onto housings. Since circuit boards have multiple test points that need to be connected to probes to test their functionality, it is crucial to ensure the relative position of the circuit board and housing, especially their relative position in the width direction. In other words, the accuracy requirement for relative position in the width direction is higher than that in the length direction during assembly. Current assembly processes typically use robotic arms or other transfer mechanisms to pick up the circuit board and transfer it to the assembly station. To meet the width-direction accuracy requirements, high-precision equipment is needed, leading to high costs. While lower-precision equipment can meet the length-direction accuracy requirements, it is difficult to guarantee the width-direction accuracy, thus affecting the yield rate and the connection between probes and test points, resulting in test failures and false rejections.

[0003] Therefore, there is an urgent need to research a device for assembling irregularly shaped circuit boards to solve the above problems. Utility Model Content

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

[0060] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0061] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​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 the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

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

[0063] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0064] like Figures 1 to 7As shown, this embodiment provides an irregularly shaped circuit board assembly device for assembling a first workpiece 1000 and a second workpiece 2000, thereby reducing equipment costs and increasing the product assembly yield. The first workpiece 1000 can be a circuit board, and the second workpiece 2000 can be a housing. The irregularly 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 pickup component 600. The system comprises: a first positioning component 200 including a first longitudinal positioning part for positioning a first workpiece 1000; a second positioning component 300 including a second longitudinal positioning part, the second longitudinal positioning part being arranged at a distance from the first longitudinal positioning part in a first direction X, and positioning the second workpiece 2000 at least in a second direction Y, such that the second workpiece 2000 is aligned with the first workpiece 1000 in the second direction Y; a first driving member 400 disposed on the base 100, and its output end being movable along the first direction X; a second driving member 500 disposed on the output end of the first driving member 400, and the output end of the second driving member 500 being movable along a third direction Z; and a picking component 600 disposed on the output end of the second driving member 500, and its picking end being capable of picking up or releasing the first workpiece 1000. The first direction X is the left-right direction, the second direction Y is the front-back direction, and the third direction Z is the up-down direction.

[0065] The above configuration allows the first drive unit 400 and the second drive unit 500 to move only in the first direction X and the third direction Z when driving the pickup component 600 to transfer the first workpiece 1000 to the second workpiece 2000 for assembly. This avoids displacement of the first workpiece 1000 in the second direction Y during the installation process, thereby ensuring the relative positional accuracy of the first workpiece 1000 and the second workpiece 2000 in the second direction Y after installation and the yield rate. Since the installation accuracy in the first direction X and the third direction Z is lower than the installation accuracy in the second direction Y, the motion accuracy requirements of the first drive unit 400 and the second drive unit 500 are reduced, thereby reducing the cost of the irregular circuit board assembly equipment.

[0066] During assembly, the first workpiece 1000 needs to be placed in the first positioning component 200, and the second workpiece 2000 needs to be placed in the second positioning component 300. To avoid interference from the pick-up component 600, in some embodiments, the irregular circuit board assembly equipment also includes a third driving component 700 and a carrier component 710. The third driving component 700 is located on the base 100, and the output end of the third driving component 700 can reciprocate along the second direction Y and is connected to the carrier component 710. The first positioning component 200 and the second positioning component 300 are both located on the carrier component 710 so as to move synchronously with the carrier component 710 along the second direction Y. The third driving component 700 can move the carrier 710 backward to below the pickup component 600 or forward to the front of the pickup component 600. When the carrier 710 is in front of the pickup component 600, the first workpiece 1000 can be placed in the first positioning component 200 and the second workpiece 2000 can be placed in the second positioning component 300 by the robot arm, without interfering with the pickup component 600.

[0067] Because the circuit board has an irregular shape, it is inconvenient to grasp it using conventional robotic arms. Therefore, in some embodiments, a combination of... Figure 2 and Figure 3 As shown, the pickup assembly 600 includes a pickup base 610, a pickup moving member 620, an elastic member 630, and a pickup head 640. The pickup base 610 is located at the output end of the second drive member 500. The pickup moving member 620 is movably disposed on the pickup base 610 along a third direction Z and can move between a lower limit position and an upper limit position. The elastic member 630 is disposed between the pickup base 610 and the pickup moving member 620 and applies a spring force to the pickup moving member 620 to move it to the lower limit position. The pickup head 640 is disposed on the pickup moving member 620, and a pickup end is disposed on the pickup head 640 to pick up the top surface of the first workpiece 1000. The elastic member 630 buffers the pressure between the pickup end and the top surface of the first workpiece 1000, preventing damage to the first workpiece 1000. Furthermore, it reduces the accuracy requirements for the movement of the second drive member 500, further reducing costs. Both the first driving component 400 and the second driving component 500 can be linear modules.

[0068] When picking up the first workpiece 1000, the pickup head 640 needs to move downwards. To avoid a large impact between the pickup head 640 and the first workpiece 1000, the moving speed of the second drive member 500 is reduced as the pickup head 640 approaches the first workpiece 1000. Before contacting the first workpiece 1000, the pickup head 640 is at its lower limit position. To ensure the timing of the second drive member 500's speed reduction, the relative position of the pickup head 640 needs to be accurate. For this purpose, the pickup assembly 600 also includes a first limiting member 650, which is connected to the pickup moving member 620. When the pickup moving member 620 is at its lower limit position, the first limiting member 650 abuts against the pickup seat 610. 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 threadedly engaged with a threaded hole in the pickup moving member 620. The pickup seat 610 has a limiting channel extending in 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 within the limiting channel and can move relative to the pickup seat 610. The limiting head 653 is located at the end of the limiting channel away from the pickup moving member 620. Furthermore, the threaded portion 651 allows the distance between the limiting head 653 and the pickup moving member 620 to be adjustable, thereby allowing the lower limit position of the pickup moving member 620 to be adjusted to accommodate first workpieces 1000 of different thicknesses.

[0069] To prevent the first limiting member 650 and the picking moving member 620 from rotating relative to each other and separating, in some embodiments, the picking assembly 600 further includes a second limiting member 660 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] For example, the second limiting member 660 has a connecting channel with threads on its sidewall. The connecting channel is threaded into the threaded portion 651. The bottom end of the second limiting member 660 abuts against the pickup moving member 620, and the top end of the second limiting member 660 abuts against the pickup seat 610 to limit the upper limit position of the pickup moving member 620. This arrangement can lock the first limiting member 650 and the pickup moving member 620, and also move synchronously with the pickup moving member 620 to limit the upper limit position of the pickup moving member 620. The second limiting member 660 is located below the limiting channel. The second limiting member 660 can be a nut or a threaded sleeve.

[0071] The pickup assembly 600 also includes a guide rod 670. The pickup seat 610 has a guide channel. The guide rod 670 is connected to the pickup moving part 620 and slidably disposed within the guide channel. The elastic element 630 is a spring, which is sleeved on the guide rod 670, with its two ends abutting against the pickup seat 610 and the pickup moving part 620, respectively. The guide rod 670 provides guidance for the pickup moving part 620, helping to ensure the movement trajectory of the pickup moving part 620; on the other hand, it also provides an installation position for the spring, preventing it from flying off and ensuring the reliability of the spring during use. In this embodiment, the threaded portion 651 makes the distance between the limiting head 653 and the pickup moving part 620 adjustable, thereby making the lower limit position of the pickup moving part 620 adjustable to adjust the spring force.

[0072] The pickup base 610 includes a pickup base plate 611 and a pickup limiting block 612, with the pickup limiting block 612 disposed on the pickup base plate 611. Both the limiting channel and the guide channel are disposed on the pickup limiting block 612, and the upper end of the elastic member 630 abuts against the pickup limiting block 612. When the second pickup moving member 620 is at its upper limit position, the upper end of the second limiting member 660 abuts against the pickup limiting block 612. When the second pickup moving member 620 is at its upper limit position, the spring is compressed, and the height of the compressed spring is a first dimension, while the height of the second limiting member 660 is a second dimension. The second dimension is greater than the first dimension to avoid damage to the spring.

[0073] Two guide rods 670 and two springs are provided, corresponding to two guide channels. The limiting channel is located between the two guide channels. The pickup base plate 611 is provided with a slide rail 613, and the pickup moving part 620 is equipped with a slider 614, which slides on the slide rail 613.

[0074] In other embodiments, the second limiting member 660 can be an elongated key with a threaded portion 651 having a first keyway and a pickup moving member 620 having a second keyway. The first and second keyways 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, and when the pickup moving member 620 moves to the upper limit position, the top end of the key abuts against the pickup limiting block 612.

[0075] A plurality of first and / or second keyways are provided. As the threaded portion 651 rotates, a plurality of limiting grooves are formed to improve the adjustment accuracy of the first limiting member 650. In some embodiments, a plurality of first keyways are provided, and at different rotation angles, the threaded portion 651 forms a plurality of limiting grooves with a plurality of first keyways and a second keyway. Similarly, in some embodiments, a plurality of second keyways are provided, which can also form a plurality of limiting grooves. In some embodiments, a plurality of first and second keyways are each provided, forming a plurality of limiting grooves during the rotation of the threaded portion 651.

[0076] In some embodiments, the pickup assembly 600 further includes a plurality of suction heads 680, which are distributed on the pickup head 640 and used to simultaneously pick up the first workpiece 1000. When the first workpiece 1000 is another part that can be attracted by a magnet, the suction heads 680 can also be replaced by magnets. Regarding the installation of the suction heads 680, in some embodiments, combined with... Figure 5 As shown, the pickup assembly 600 also includes a pressure plate 642. The pickup head 640 has a pickup groove, a gas hole communicating with the pickup groove, and several mounting holes. The pressure plate 642 is sealed at the opening of the pickup groove, forming a pickup cavity 641. Several suction heads 680 are installed in the mounting holes one-to-one, with one end of each suction head 680 communicating with the pickup cavity 641 and the other end communicating with the outside. The gas hole can communicate with an external vacuum device. The four mounting holes are arranged in a 2×2 matrix or according to the reasonable local arrangement of the structure of the first workpiece 1000.

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

[0078] During the production process, the first workpiece 1000 is prone to scratches or bending damage during transfer. Therefore, the first positioning assembly 200 includes a first carrier 210 for supporting the first workpiece 1000. The first positioning assembly 200 also includes a first longitudinal positioning block 220, which forms a first longitudinal positioning portion along one side wall of the first longitudinal positioning block 220 in the second direction Y. The first carrier 210 abuts against the first longitudinal positioning portion along one side wall of the first longitudinal positioning block 220 in the second direction Y. The first positioning assembly 200 also includes a first transverse positioning block 230, which forms a first transverse positioning portion along one side wall of the first direction X. The first carrier 210 abuts against the first transverse positioning portion along one side wall of the first transverse positioning block 230 in the first direction X. The first carrier 210 ensures the safety of the first workpiece 1000 during transfer between various workstations. Meanwhile, 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, making it easy for the pickup head 640 to pick it up. In this embodiment, the positioning hole is provided on the first carrier 210.

[0079] The first positioning component 200 also includes a magnetic attractor, which is disposed on the first longitudinal positioning block 220 to attract the first carrier 210. A magnetic attractor is disposed on the first transverse positioning block 230 to attract the first carrier 210, thereby fixing the first carrier 210 in place and preventing vibrations generated during assembly from causing a shift in the relative position of the first carrier 210 and the support member 710. The magnetic attractor is a permanent magnet.

[0080] After the first workpiece 1000 is removed from the first carrier 210, the first carrier 210 needs to be removed from the support member 710 to replace the next first carrier 210 carrying the first workpiece 1000. To improve the convenience of the first carrier 210, in some embodiments, the first positioning assembly 200 further includes an unloading member 240. The first longitudinal positioning block 220 is provided with a longitudinal channel extending along the second direction Y. The unloading member 240 is disposed on the first longitudinal positioning block 220. The output end of the unloading member 240 can reciprocate along the second direction Y. The output end of the unloading member 240 can extend out of the longitudinal channel and push against the first carrier 210, causing the first carrier 210 to overcome the magnetic force and move away from the first longitudinal positioning block 220. The output end of the unloading member 240 can also be concealed within the longitudinal channel so that the first carrier 210 can fit against the first longitudinal positioning block 220. The unloading member 240 is a cylinder, and the output end of the cylinder is provided with a push rod, which is slidably disposed in the longitudinal channel. In the second direction Y, the distance between the magnetic suction element on the first transverse positioning block 230 and the first longitudinal positioning part is the first length, and the length of the output end of the unloading element 240 extending out of the longitudinal channel is the second length, which is greater than the first length. The above-mentioned size limitation allows one unloading element 240 to help the first carrier 210 overcome the magnetic forces in two directions, thereby easily completing the disassembly of the first carrier 210.

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

[0082] To prevent damage to the second workpiece 2000 during the transfer process, in some embodiments, the second positioning assembly 300 includes a second carrier 310 for supporting the second workpiece 2000. The second positioning assembly 300 also includes a second longitudinal positioning block 320, which forms a second longitudinal positioning portion along one side wall of the second direction Y. The second carrier 310 abuts against the second longitudinal positioning portion along one side wall of the second direction Y. The second positioning assembly 300 also includes a second transverse positioning block 330, which forms a second transverse positioning portion along one side wall of the first direction X. The second carrier 310 abuts against the second transverse positioning portion along one side wall of the first direction X. Simultaneously, the arrangement of the second longitudinal positioning block 320 and the second transverse positioning block 330 limits the second carrier 310 in the horizontal direction, thereby ensuring the specific horizontal position of the second workpiece 2000 and facilitating its engagement with the first workpiece 1000. A magnetic suction element is provided on the second longitudinal positioning block 320 to attract the second carrier 310. A magnetic attractor is provided on the second transverse positioning block 330 to attract the second carrier 310. The second longitudinal positioning block 320 is also provided with a discharge component 240 to separate the second carrier 310 from the second longitudinal positioning block 320, and at the same time, to separate the magnetic attractor on the second carrier 310 from the second transverse positioning block 330.

[0083] In some embodiments, the first lateral positioning block 230 and the second lateral positioning block 330 are arranged at intervals along a first direction X, and the first carrier 210 and the second carrier 310 are located between the first lateral positioning block 230 and the second lateral positioning block 330. This arrangement provides ample installation space for the placement of the first carrier 210 and the second carrier 310; furthermore, even after the dimensions of the first carrier 210 and the second carrier 310 change accordingly, they can still be positioned by the first lateral positioning block 230 and the second lateral positioning block 330. For example, along the first direction X, if 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 less than the distance between the first lateral positioning block 230 and the second lateral positioning block 330, they can both be placed between the first lateral positioning block 230 and the second lateral positioning block 330.

[0084] Combination Figure 6 and Figure 7As shown, the second carrier 310 includes a carrier plate 311, a linkage assembly, a longitudinal movable block 312, and a transverse movable block 313. The carrier plate 311 is provided with a longitudinal stop block 3111 and a transverse stop block 3112. 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 stop block 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 stop block 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 mounted on the support plate 311. The longitudinal connecting rod 315 is slidably mounted on the support plate 311 along a first direction X, with one end abutting against the outer periphery of the cam rod 314. The longitudinal connecting rod 315 has a first inclined surface 3151, which is inclined towards the longitudinal stop block 3111 in a direction away from the cam rod 314. The longitudinal movable block 312 is flush with the first inclined surface 3151. The second inclined surface 3121 is in contact with the cam rod 314. Rotation of the cam rod 314 can drive the longitudinal connecting rod 315 to move, and drive the longitudinal movable block 312 away from the longitudinal stop block 3111. The transverse connecting rod 316 is slidably disposed on the bearing plate 311 along the first direction X, with one end in contact with the outer periphery of the cam rod 314 and the other end connected to the transverse movable block 313. Rotation of the cam rod 314 can drive the transverse connecting rod 316 to move, and drive the transverse movable block 313 away from the transverse stop block 3112.

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

[0087] The longitudinal elastic element 630 is disposed between the longitudinal movable block 312 and the bearing plate 311, and is used to drive the longitudinal movable block 312 closer to the longitudinal stop block 3111; the transverse elastic element 630 is disposed between the transverse movable block 313 and the bearing plate 311, and is used to drive the transverse movable block 313 closer to the transverse stop block 3112.
