Description

Technical Field

[0001] This invention relates to the field of assembly technology, and more specifically to a workpiece mounting device. Background Technology

[0002] For assembly systems, assembly efficiency and placement accuracy are two important indicators.

[0003] In the chip manufacturing process, magnets need to be precisely connected to pins (leads), as one or more pins need to be mounted on a single mounting surface of the magnet. The traditional mounting process typically includes the following key steps: applying adhesive to the mounting position on the magnet's mounting surface, and then mounting the pins to the corresponding mounting positions after the adhesive is applied.

[0004] In existing technologies, apart from the dispensing process where adhesive can be applied to the magnets using dispensing equipment, the mounting process is typically done manually. However, manual operation makes it difficult to guarantee the mounting accuracy and consistency of each pin. Since multiple pins may need to be mounted on a single mounting surface of the magnet, and the pins are relatively small, misalignment between the magnet and the pin mounting positions can occur during the mounting process. Furthermore, manual assembly is slow and inefficient, becoming a bottleneck in large-scale production environments. Utility Model Content

[0052] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0053] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] Example 1, as Figures 1 to 8 A workpiece mounting apparatus includes a workpiece mounting device 1, in which a first workpiece 3 and a second workpiece 4 are mounted. In this embodiment, the first workpiece 3 is a magnet, and the second workpiece 4 is an inductor pin.

[0056] Specifically, the first workpiece 3 is conveyed to the first position by the first feeding mechanism 11, and the orientation of the assembly surface of the first workpiece 3 is adjusted. The first feeding mechanism 11 uses a vibratory feeder, which can flip the magnet during the conveying process, thereby adjusting the assembly angle of the magnet and ensuring that the required assembly surface of the magnet is facing down. The first position here refers to the position where the magnet is gripped by the mounting device 16. The vibratory feeder conveys the magnet to this position for the mounting device 16 to grip it.

[0057] Specifically, at least one second workpiece 4 is conveyed to the second position via the second feeding mechanism 12. The second feeding mechanism 12 is a cutting feeding mechanism, which includes a tray 121 for conveying the conveyor belt 2. The second workpiece 4 and the conveyor belt 2 are integrated, and the conveyor belt 2 is transported via a ratchet. The conveyor belt 2 has multiple second workpieces 4, and the number of second workpieces 4 is consistent with the number of slots to be mounted on the assembly surface of the first workpiece 3. Since the number of second workpieces 4 at the second position may be different depending on the mounting requirements of the first workpiece 3, the second position is the position where all the second workpieces 4 enter the position to be cut and dispensed.

[0058] Furthermore, the material belt 2 has corresponding positioning holes on both sides. The second feeding mechanism 12 also includes a rotatable feeding ratchet 122. The feeding ratchet 122 has multiple positioning pins 123 on its circumference. When the feeding ratchet 122 rotates, the positioning pins 123 will enter the positioning holes. As the feeding ratchet 122 rotates, the material belt 2 will be pushed forward, thereby ensuring that the second workpiece 4 on the material belt 2 can be accurately moved to the second position.

[0059] Furthermore, this embodiment employs a three-axis motion mechanism 13, which includes a Y-axis motion mechanism 131, an X-axis motion mechanism 132, and a Z-axis motion mechanism 133. The Y-axis motion mechanism 131 is connected to the gantry. The X-axis motion mechanism 132 is connected to the Y-axis motion mechanism 131. The Z-axis motion mechanism 133 is connected to the X-axis motion mechanism 132.

[0060] Specifically, the Y-axis motion mechanism 131 includes a Y-axis lead screw module. The X-axis motion mechanism 132 includes a stator and a mover mounted on the Y-axis lead screw module. The Z-axis motion mechanism 133 includes a Z-axis lead screw module mounted on the mover.

[0061] Preferably, the mounting plate of the Z-axis lead screw module is provided with a cutting device 14, a dispensing device 15, a mounting device 16, and a first vision module 17.

[0062] Specifically, the cutting device 14 is located on the far left of the mounting plate. The cutting device 14 includes a cutting cylinder 141, a cutting head 142, and a positioning pin 143. The cutting head 142 is a contour cutting head.

[0063] Below the cutting device 14 is a cutting base 144, which is driven to lift by a cylinder 145. Vacuum adsorption holes 146 are correspondingly opened on the cutting base 144, corresponding to each of the second workpieces 4 and located on both sides of the bottom surface of the second workpiece 4, thereby ensuring effective adsorption of the second workpiece 4 and preventing displacement of the second workpiece 4 during cutting and dispensing. After mounting is completed, vacuum adsorption is stopped, at which point the second workpiece 4 can follow the first workpiece 3 away from the second position.

[0064] The X-axis motion mechanism 132 and the Y-axis motion mechanism 131 drive the cutting device 14 to be directly above the second position. The cutting base 144 moves upward and attracts the second workpiece 4. Then, the Z-axis motion mechanism 133 drives the cutting device downward. The positioning pin 143 is inserted into the positioning hole of the lower positioning plate to achieve position correction. Then, the cutting cylinder 141 drives the cutting head 142 downward. The cutting head 142 cuts the second workpiece 4 off the material belt 2.

[0065] Specifically, the tape 2 is divided into multiple blocks according to the mounting requirements, and each block has a number of second workpieces 4 corresponding to the mounting surface. When the mounting surface of the first workpiece 3 needs to mount several second workpieces 4, the corresponding block on the tape 2 moves to the second position, and then the cutting head 142 cuts all the second workpieces 4 off the tape 2 in one go, followed by the glue dispensing operation.

[0066] Specifically, the dispensing device 15 is located to the right of the cutting device 14 and is also staggered in front and behind. The dispensing device 15 uses an existing dispensing valve to dispense glue to each of the cut second workpieces 4 in sequence. After the cutting device 14 completes the cutting, the Z-axis motion mechanism 133 moves upward to move the cutting device 14 away from the second position. Then, the X-axis motion mechanism 132 and the Y-axis motion mechanism 131 work again to adjust the position of the dispensing device 15 so that the dispensing device 15 is above the second position. The Z-axis motion mechanism 133 moves downward to move the dispensing device 15 to the second workpiece 4 for dispensing. After dispensing glue to one second workpiece 4, the dispensing device 15 only needs to move along the arrangement direction of the second workpieces 4 and repeat the above steps to complete the dispensing operation for all the cut second workpieces 4 in sequence, which greatly improves the dispensing efficiency.

[0067] To avoid interference between the device that is not in operation during the dispensing or cutting process and the second feeding mechanism 12, the cutting device 14 and the dispensing device 15 are spatially staggered to ensure that cutting and dispensing can be carried out smoothly.

[0068] Specifically, the mounting device 16 is located to the right of the cutting device 14. The mounting device 16 includes grippers 161. Grippers 161 can be flexible grippers or pneumatic grippers. A U-axis motor 162 is connected above grippers 161, and the angle of grippers 161 can be adjusted by the U-axis motor 162. The X-axis motion mechanism 132 and the Y-axis motion mechanism 131 drive the mounting device 16 to move above the first position, and the Z-axis motion mechanism 133 drives the mounting device 16 to move downward and grasp the first workpiece 3 at the first position. Before the first workpiece 3 is transferred to the second position, the first workpiece 3 is photographed by the second vision module 18. If there is a deviation in the assembly angle of the first workpiece 3, the grippers 161 are finely adjusted on the U-axis by the U-axis motor 162, thereby ensuring the mounting accuracy in the later stage. Then, the mounting device 16 is driven to move above the second position by the X-axis motion mechanism 132 and the Y-axis motion mechanism 131, and the mounting device 16 is driven downward by the Z-axis motion mechanism 133 to move the first workpiece 3 into the second position, and the second workpiece 4 is mounted on the mounting surface of the first workpiece 3. Similarly, the mounting device 16 and the dispensing device 15 are spaced apart to avoid interference between the dispensing device 15 and the cutting device 14 and the first feeding mechanism 11 and the second feeding mechanism 12 during the process of the mounting device 16 gripping and mounting the first workpiece 3.

[0069] Specifically, the first vision module 17 is located on the right side of the mounting device 16. Before the mounting device 16 grips the first workpiece 3, the first vision module 17 captures the position of the first workpiece 3 to ensure accurate gripping of the first workpiece 3. Before mounting the first workpiece 3 and the second workpiece 4, the first vision module 17 also needs to capture the position of the second workpiece 4 to ensure that the mounting surface of the first workpiece 3 corresponds to the second workpiece 4, thus completing the accurate mounting process.

[0070] Since the cutting device 14, the dispensing device 15, and the mounting device 16 are mounted on the same set of three-axis motion mechanisms 13, the cutting, dispensing, gripping, and mounting processes can be achieved step-by-step through this single set of mechanisms, reducing the overall machine cost and simplifying the control method. Furthermore, because the cutting device 14, dispensing device 15, and mounting device 16 are spaced apart on the X-axis and staggered on the Y-axis, this spatial misalignment avoids mutual interference during operation.

[0071] It should be noted that in this embodiment, the first workpiece 3 is mounted onto the second workpiece 4. The mounting positions of the second workpiece 4 located on the material strip 2 have been determined according to the assembly requirements. During the subsequent cutting and dispensing processes, the position of the second workpiece 4 in the second position will not change. As long as the assembly surface of the first workpiece 3 is aligned with the second workpiece 4 in the second position, the mounting of one assembly surface of the first workpiece 3 can be completed in one mounting process. Compared with the mounting method of mounting the second workpiece 4 onto the first workpiece 3, this mounting process effectively improves mounting efficiency and mounting accuracy. Since the dispensing device 15, the cutting device 14, and the mounting device 16 are on the same three-axis motion mechanism 13, the stroke required by the three-axis motion mechanism 13 is relatively small when switching processes, and it can quickly switch between the cutting device 14, the dispensing device 15, and the mounting device 16, improving mounting efficiency and reducing costs.

[0072] The workpiece assembly production line of this embodiment can be adapted to different workpiece mounting requirements. As long as the first workpiece 3 and the second workpiece 4 are in the corresponding mounting positions, the workpiece mounting can be completed. It is not limited to the mounting of magnets and PINs in this embodiment.

[0073] Example 2, as Figures 9 to 12 Two sets of three-axis motion mechanisms 13 are adopted, and the two sets of three-axis motion mechanisms 13 share a Y-axis. The X-axis motion mechanism 132, Y-axis motion mechanism 131 and Z-axis motion mechanism 133 are the same as in Embodiment 1, and will not be described again here.

[0074] The mounting device 16 and the first vision module 17 are connected to a set of three-axis motion mechanisms 13. The cutting device 14 and the dispensing device 15 are connected to another set of three-axis motion mechanisms 13. By using two sets of three-axis motion mechanisms 13 to separate the mounting step from the cutting and dispensing steps, it is easier to achieve avoidance between the cutting device 14, the dispensing device 15, and the mounting device 16. The two sets of three-axis motion mechanisms 13 can operate synchronously, so that while cutting and dispensing the second workpiece 4, the mounting device 16 can simultaneously grasp the first workpiece 3.

[0075] Since the cutting and dispensing processes take less time than the mounting process, the cutting device 14 and the dispensing device 15 are located in the same three-axis motion mechanism. This improves the mounting efficiency of the first workpiece 3 and the second workpiece 4. Two second feeding mechanisms 12 can be set up as needed to further improve mounting efficiency.

[0076] Specifically, the second workpiece 4 is fed through two sets of second feeding mechanisms 12. The cutting device 14 and the dispensing device 15 can operate on both sets of second feeding mechanisms 12 at the same time. After the cutting and dispensing of the second workpiece 4 is completed on one set of second feeding mechanisms 12, the mounting device 16 can perform the mounting. At this time, the cutting device 14 and the dispensing device 15 can process the other set of second feeding mechanisms 12, thus further improving the mounting efficiency.

[0077] Furthermore, the number of cutting devices 14 can also be two, with the two cutting devices 14 located on the left and right sides of the mounting device 16. For example... Figure 10 As shown, since there are two sets of second feeding mechanisms, in order to avoid limiting the movement space of the cutting device 14 on the X-axis, two cutting devices 14 are set to ensure that the cutting device 14 can cut the second workpiece 4. The rest of the structure is the same as in Embodiment 1.

[0078] Of course, this application is not limited to the above embodiments. When selecting two sets of three-axis motion mechanisms, as long as one of the cutting device 14, the dispensing device 15, and the mounting device 16 is installed on one set of three-axis motion mechanisms 13, and the other two are installed on the other set of three-axis motion mechanisms 13, the two devices installed on the same set of three-axis motion mechanisms are arranged sequentially on the X-axis and staggered on the Y-axis to meet the processing requirements of mutual avoidance.

[0079] Specifically, in embodiment 3, two sets of three-axis motion mechanisms 13 are used. The mounting device 16 and the cutting device 14 are mounted on the same set of three-axis motion mechanisms 13, and the dispensing device 15 is mounted on the other set of three-axis motion mechanisms 13. The working principle is the same as in embodiment 2.

[0080] Specifically, in embodiment 4, two sets of three-axis motion mechanisms 13 are used. The mounting device 16 and the dispensing device 15 are mounted on the same set of three-axis motion mechanisms 13, while the cutting device 14 is mounted on the other set of three-axis motion mechanisms 13. The working principle is the same as in embodiment 2.
