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

[0063] 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.

[0064] 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.

[0065] 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.

[0066] Example 1, such as Figures 1 to 9 As shown, a workpiece mounting apparatus 1 is used to mount a first workpiece 3 and a second workpiece 4. In this embodiment, the first workpiece 3 is a magnet, and the second workpiece 4 is an inductor pin.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Furthermore, in this embodiment, the number of the second feeding mechanism 12 is one.

[0071] In this embodiment, the second feeding mechanism 12 is arranged along the Y-axis, and the dual-axis motion mechanism 19 is arranged along the X-axis.

[0072] Specifically, the dual-axis motion mechanism 19 includes an x-axis motion mechanism 191 and a z-axis motion mechanism 193. The x-axis motion mechanism 191 is mounted on the machine base, and the z-axis motion mechanism 193 is mounted on the x-axis motion mechanism 191. The cutting device 14 is mounted on the z-axis motion mechanism 193.

[0073] 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.

[0074] 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.

[0075] The cutting device 14 is driven by the x-axis motion mechanism 191 to be directly above the second position. The cutting base 144 moves upward and adsorbs the second workpiece 4. The z-axis motion mechanism 193 drives the cutting device 14 downward. The positioning pin 143 is inserted into the positioning hole of the lower positioning plate to realize the position correction. Then the cutting cylinder 141 drives the cutting head 142 downward, and the cutting head 142 cuts the second workpiece 4 off the material belt 2.

[0076] 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. After the cutting is completed, the cutting device 14 is driven away from the second position by the x-axis motion mechanism 191 and the z-axis motion mechanism 193 to avoid interference between the cutting device 14 and the glue dispensing device 15 and the mounting device 16 during the glue dispensing and mounting processes.

[0077] Specifically, the dispensing device 15, the mounting device 16, and the first vision module 17 are mounted on the three-axis motion mechanism 13. The dispensing device 15 and the mounting device 16 are arranged back to back, avoiding each other in space, and the movement stroke of the three-axis motion mechanism 13 can be reduced when switching between the dispensing and mounting processes.

[0078] After the cutting device 14 completes the cutting, the X-axis motion mechanism 132 and the Y-axis motion mechanism 131 drive the dispensing device 15 to move above the second position. Then, the Z-axis motion mechanism 133 moves down to move the dispensing device 15 onto the second workpiece 4 for dispensing. After dispensing one second workpiece 4, the dispensing device 15 only needs to move along the arrangement direction of the second workpiece 4. Then, the above steps are repeated to complete the dispensing operation for all the cut second workpieces 4 in sequence, which greatly improves the dispensing efficiency.

[0079] Specifically, 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 via the U-axis motor 162. After dispensing is completed, the Z-axis motion mechanism 133 moves the dispensing device 15 upward to leave the second position, and then the X-axis motion mechanism 132 and Y-axis motion mechanism 131 drive the mounting device 16 to reach above the first position. The Z-axis motion mechanism 133 then drives the mounting device 16 downward to 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 via the U-axis motor 162 to ensure the mounting accuracy in the later stages. Then, the mounting device 16 is driven to move to the second position by the X-axis motion mechanism 132 and the Y-axis motion mechanism 131, and the mounting device 16 is driven to move down 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.

[0080] Furthermore, 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.

[0081] The cutting device 14 and the dispensing device 15 are mounted on different motion mechanisms, which shortens the time of the cutting and dispensing processes and improves production efficiency. At the same time, the cutting device 14 is mounted on the dual-axis motion mechanism 19, and the dispensing device 15 and the mounting device 16 are mounted on the three-axis motion mechanism 13, which makes the overall space utilization more efficient, makes it easier for the devices to avoid each other in space, and makes the layout between the devices more compact.

[0082] Preferably, a pre-curing treatment is used when mounting the first workpiece 3 and the second workpiece 4 to ensure a firm fit and prevent the second workpiece 4 from detaching from the first workpiece 3 during subsequent movement. Depending on the dispensing process requirements, a UV lamp or heat curing component can be installed on the mounting device 16 or the second feeding mechanism 12.

[0083] 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 process, the position of the second workpiece 4 located 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 the mounting efficiency and mounting accuracy.

[0084] 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.

[0085] Example 2, as Figures 10 to 12 As shown, it has two sets of second feeding mechanisms arranged along the Y-axis and two sets of dual-axis motion mechanisms 19, which correspond to each other to form a dual-station layout.

[0086] The dual-axis motion mechanism 19 includes a y-axis motion mechanism 192 and a z-axis motion mechanism 193. The y-axis motion mechanism 192 is mounted on the machine base; the z-axis motion mechanism 193 is mounted on the y-axis motion mechanism 192. A cutting device 14 is mounted on the z-axis motion mechanism 193. A dispensing device 15 is located on the back of the cutting device 14. The y-axis motion mechanism 192 drives the cutting device 14 to a second position via the z-axis motion mechanism 193 to cut the second workpiece 4, following the same cutting process as in Embodiment 1. After cutting, the z-axis motion mechanism 193 drives the cutting device 14 away from the second position, and then the y-axis motion mechanism 192 drives the dispensing device 15 to the second position to dispense adhesive, following the same dispensing process as in Embodiment 1. Simultaneously, the cutting device 14 and the dispensing device 15, positioned opposite each other, are spatially complementary. During the transition between the cutting and dispensing processes, the stroke of the dual-axis motion mechanism 19 is minimal, resulting in a fast transition speed and improved processing efficiency.

[0087] Since the cutting and dispensing processes require less time than the mounting process, the cutting device 14 and dispensing device 15 are driven by a dual-axis motion mechanism 19. While the cutting device 14 and dispensing device 15 are operating, the mounting device 16 can simultaneously pick up the first workpiece 3, allowing for immediate mounting after the dispensing process, thus improving mounting efficiency. At this time, the cutting device 14 and dispensing device 15 can also perform cutting and dispensing on another set of second feeding mechanisms 12. After the mounting device 16 completes the previous mounting, it can directly pick up another first workpiece 3 and then proceed to the second feeding mechanism 12 for mounting. The mounting device 16, cutting device 14, and dispensing device 15 operate on different motion mechanisms without interference, resulting in a more optimized spatial arrangement and higher mounting efficiency compared to Embodiment 1.
