Description

Technical Field

[0001] The present invention relates to the field of assembly technology, and particularly relates to a workpiece assembly production line and a workpiece assembly method. Background Art

[0002] For an assembly operation system, assembly efficiency and mounting accuracy are two important indicators.

[0003] During the production process of a chip, it is necessary to precisely connect a magnet to a PIN (pin). Since one or more PINs (pins) need to be mounted on a single mounting surface of the magnet. The traditional mounting process usually includes the following key steps: applying glue at the mounting position on the mounting surface of the magnet, and then mounting the PIN to the corresponding mounting position after glue application.

[0004] In the prior art, except that the glue application process can use a glue application device to apply glue to the magnet, the mounting process usually uses manual mounting. However, on the one hand, it is difficult to ensure the mounting accuracy and consistency of each PIN by manual operation. Since multiple PINs (pins) may need to be mounted on a single mounting surface of the magnet, and the volume of the PINs (pins) is relatively small, deviations occur in the mounting positions of the magnet and the PINs (pins) during the mounting process. At the same time, the speed of manual assembly is slow and the efficiency is low. In a large-scale production environment, manual assembly will become a bottleneck in the production line. Summary of the Invention

[0081] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0082] In the description of the present invention, 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", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0083] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "mount", "connect", "couple" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0084] Example 1, as Figures 1 to 11 shown, a workpiece assembly production line includes multiple workpiece mounting devices 1 and a curing and conveying device 2. The mounting of the first workpiece 3 and the second workpiece 4 is completed in the workpiece mounting device 1. After the mounting, the assembled workpiece enters the next workpiece mounting device 1 for mounting on another mounting surface of the second workpiece 4 until the mounting of all mounting surfaces of the first workpiece 3 is completed. The assembled workpiece after mounting is cured during the conveying process by the curing and conveying device 2. Among them, the assembled workpiece refers to the workpiece formed after the first workpiece 3 and the second workpiece 4 are mounted one or more times.

[0085] In this embodiment, the first workpiece 3 is a magnet, and the second workpiece 4 is an inductor PIN (pin). Generally, a magnet has 4 surfaces that require inductor PINs, and different numbers of inductor PINs need to be mounted on each surface according to the product design requirements. There are slots corresponding to the inductor PINs on the surfaces of the magnet, and the slots correspond to the mounting surfaces of the single inductor PIN. The workpiece after mounting is as Figure 11 shown.

[0086] The workpiece mounting device 1 includes a first feeding mechanism 11 and a second feeding mechanism 12.

[0087] Specifically, the first feeding mechanism 11 conveys the first workpiece 3 to the first position and adjusts the orientation of the mounting surface of the first workpiece 3. The first feeding mechanism includes a carrying component 111. The first workpiece 3 is placed on the carrying component 111, and the carrying component 111 moves along the X-axis to convey the first workpiece 3 to the first position (as shown by the arrow a in Figure 4 ). The carrying component 111 is installed on the linear motor module 1112 to achieve movement along the X-axis. The first position here refers to the position where the magnet is grabbed by the mounting device 16. The vibrating bowl conveys the magnet to this position for the mounting device 16 to grab the magnet.

[0088] Furthermore, the carrying component 111 can also move along the Z-axis and convey the first workpiece 3 to the flipping component 112. The flipping component 112 clamps and flips the first workpiece 3. Both the carrying component 111 and the flipping component 112 are arranged on the base 1111, and the base 1111 is connected to the linear motor module 1112 and moves along the X-axis. The carrying component 111 has a bearing platform 1113 for placing the workpiece, and the bearing platform 1113 is driven to lift by a Z-axis slide cylinder 1114. The clamping part 1121 is driven by a Y-axis slide cylinder 1123 and clamps the workpiece through the clamping head 1124 at the upper end. The clamping head 1124 is driven by a rotary cylinder 1122 to rotate to flip the second workpiece 4.

[0089] The first workpiece 3 is lifted by the carrying component 111 to the flipping component 112. The flipping component 112 includes two symmetrically arranged clamping parts 1121, and the clamping parts 1121 are installed on the Y-axis slide cylinder 1123. The clamping parts 1121 can move relatively closer to or away from each other along the Y-axis, and a clamping head 1124 is rotatably connected to the clamping parts 1121. A rotary cylinder 1122 is provided on one of the clamping parts 1121, and the rotary cylinder 1122 is connected to the clamping head. A connecting shaft is installed behind the clamping head 1124, and the connecting shaft is connected to the output end of the rotary cylinder 1122. Moreover, the connecting shaft translates along the Y-axis within the output end and is driven by the output end to rotate around the Y-axis. The output end is provided with a connecting hole, and the connecting shaft can translate along the Y-axis within the connecting hole. The connecting shaft is circumferentially limited by the connecting hole in the Y-axis direction. Through the cooperation of the connecting shaft and the connecting hole, the circumferential limitation of the connecting shaft is achieved, which can ensure that the rotary cylinder 1122 can drive the connecting shaft to rotate. At the same time, in order to ensure that the clamping part 1121 can translate on the Y-axis, the connecting shaft can slide within the connecting hole to ensure the freedom of movement in the Y-axis direction. Of course, the same effect can also be achieved by using a linear bearing between the rotary cylinder 1122 and the connecting shaft.

[0090] When the carrying component 111 lifts the first workpiece 3 upward to the flipping component 112, the clamping parts 1121 are driven by the Y-axis slide cylinder 1123 and move towards the first workpiece 3, and the clamping heads 1124 on the clamping parts 1121 clamp the first workpiece 3. Then, the rotary cylinder 1122 drives the clamping heads 1124 to rotate, thereby flipping the first workpiece 3 and adjusting the assembly surface of the first workpiece 3.

[0091] Of course, the first feeding mechanism 11 can also adopt a vibrating disk. The vibrating disk can flip the magnet during the process of transporting the magnet, thereby adjusting the assembly angle of the magnet. Here, the assembly angle refers to the end face of the magnet to be mounted, ensuring that the required assembly surface of the magnet is downward.

[0092] Specifically, the second feeding mechanism 12 transports at least one second workpiece 4 to the second position (as shown by the arrow b in Figure 7 ). The second feeding mechanism 12 adopts a cutting and feeding mechanism, including a tray 121 for transporting a tape 5. The second workpiece 4 and the tape 5 are integrated, and the transportation of the tape 5 is realized through a ratchet. There are multiple second workpieces 4 on the tape 5, and the number of second workpieces 4 is the same as the number of grooves to be mounted on the assembly surface of the first workpiece 3. Due to the mounting requirements of the first workpiece 3 for surface mounting, there may be different numbers of second workpieces 4 at the second position. Therefore, the second position is the position where all the second workpieces 4 enter for cutting and dispensing glue.

[0093] Further, corresponding positioning holes are provided on both sides of the strip 5. The second feeding mechanism 12 further includes a rotatable feeding ratchet 122. A plurality of positioning posts 123 are provided on the circumference of the feeding ratchet 122. When the feeding ratchet 122 rotates, the positioning posts 123 will enter the positioning holes. As the feeding ratchet 122 rotates, the strip 5 will be pushed forward, so as to ensure that the second workpiece 4 on the strip 5 can be accurately moved to the second position.

[0094] Further, in this embodiment, the number of the second feeding mechanisms 12 is 1.

[0095] 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.

[0096] 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 installed on the machine table, and the z-axis motion mechanism 193 is installed on the x-axis motion mechanism 191. The cutting device 14 is installed on the z-axis motion mechanism 193.

[0097] Specifically, the cutting device 14 is arranged at the leftmost side 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 adopts a profiling head.

[0098] Below the cutting device 14, there is a cutting base 144. The cutting base 144 is driven to lift by a cylinder 145. Corresponding vacuum adsorption holes 146 are provided on the cutting base 144. The vacuum adsorption holes 146 correspond to each second workpiece 4 and are located on both sides of the bottom surface of the second workpiece 4, so as to ensure effective adsorption of the second workpiece 4 and ensure that the second workpiece 4 does not displace during cutting and dispensing. After the mounting is completed, the vacuum adsorption is stopped, and at this time, the second workpiece 4 can leave the second position following the first workpiece 3.

[0099] The cutting device 14 is driven by the x-axis motion mechanism 191 to move to 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 to move downward. The positioning pin 143 is inserted into the positioning hole of the lower positioning plate to realize position correction. Then, the cutting cylinder 141 drives the cutting head 142 to move downward, and the cutting head 142 cuts the second workpiece 4 from the strip 5.

[0100] Specifically, the strip 5 is divided into multiple blocks according to the pick-and-place requirements, and each block has the same number of second workpieces 4 as the pick-and-place surface. When several second workpieces 4 need to be pick-and-placed on the pick-and-place surface of the first workpiece 3, the corresponding block on the strip 5 enters the second position, and then the cutting head 142 cuts once to cut all the second workpieces 4 from the strip 5, and then the dispensing operation is carried out. After the cutting is completed, the cutting device 14 is driven by the x-axis movement mechanism 191 and the z-axis movement mechanism 193 to leave the second position to avoid interference between the cutting device 14 and the dispensing device 15 and the pick-and-place device 16 during the dispensing and pick-and-place processes.

[0101] Specifically, the dispensing device 15, the pick-and-place device 16, and the first vision module 17 are installed on the three-axis movement mechanism 13. The dispensing device 15 and the pick-and-place device 16 are arranged back to back and avoid each other in space, and the movement stroke of the three-axis movement mechanism 13 can be reduced when switching between the dispensing process and the pick-and-place process.

[0102] After the cutting device 14 finishes cutting, the X-axis movement mechanism 132 and the Y-axis movement mechanism 131 drive the dispensing device 15 above the second position, and then the Z-axis movement mechanism 133 moves downward to move the dispensing device 15 to the second workpiece 4 for dispensing, dispensing the pick-and-place surface of each second workpiece 4. After dispensing one second workpiece 4, the dispensing device 15 only needs to move along the arrangement direction of the second workpieces 4, and then repeat the above steps to complete the dispensing operation for all the cut second workpieces 4 in turn, greatly improving the dispensing efficiency.

[0103] Specifically, the pick-and-place device 16 includes a clamping jaw 161. The clamping jaw 161 can be a flexible clamping jaw or a cylinder clamping jaw. The U-axis motor 162 is connected above the clamping jaw 161, and the angle of the clamping jaw 161 can be adjusted through the U-axis motor 162. After dispensing is completed, the Z-axis movement mechanism 133 moves upward to make the dispensing device 15 leave the second position, and then the X-axis movement mechanism 132 and the Y-axis movement mechanism 131 drive the pick-and-place device 16 above the first position, and the Z-axis movement mechanism 133 drives the pick-and-place 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 clamping jaw 161 is finely adjusted on the U-axis by driving the U-axis motor 162, so as to ensure the pick-and-place accuracy in the later stage. Then, the X-axis movement mechanism 132 and the Y-axis movement mechanism 131 drive the pick-and-place device 16 to move above the second position, and the Z-axis movement mechanism 133 drives the pick-and-place device 16 downward to make the first workpiece 3 enter the second position, and the second workpiece 4 is pick-and-placed on the assembly surface of the first workpiece 3.

[0104] Further, the first vision module 17 is arranged on the right side of the mounting device 16. Before the mounting device 16 grasps the first workpiece 3, the first vision module 17 photographs the position of the first workpiece 3 to ensure accurate clamping of the first workpiece 3. Before the first workpiece 3 and the second workpiece 4 are mounted, the first vision module 17 also needs to photograph the position of the second workpiece 4 to ensure that the mounting surface of the first workpiece 3 corresponds to the second workpiece 4, completing the accurate mounting step.

[0105] The cutting device 14 and the dispensing device 15 are arranged on different motion mechanisms, so the time of the cutting process and the dispensing process is shortened, improving the production efficiency. At the same time, the cutting device 14 is arranged on the dual-axis motion mechanism 19, and the dispensing device 15 and the mounting device 16 are arranged on the three-axis motion mechanism 13, making the overall space utilization rate higher, and it is easier for each device to form an avoidance in space, and the layout between the devices is more compact.

[0106] Preferably, when the first workpiece 3 and the second workpiece 4 are mounted, a pre-curing treatment is adopted to make the mounting of the first workpiece 3 and the second workpiece 4 firm, avoiding the second workpiece 4 falling off the first workpiece 3 during subsequent movement. According to the dispensing process requirements, a UV lamp or a heat curing component can be arranged on the mounting device 16 or the second feeding mechanism 12.

[0107] Specifically, after mounting one mounting surface of the first workpiece 3, the mounting device 16 places the assembled workpiece on the first feeding mechanism 11 of the next workpiece mounting device 1, sends the assembled workpiece into the next workpiece mounting device 1, and repeats the above steps until the mounting of all mounting surfaces of the first workpiece 3 is completed.

[0108] Further, the material taking device also includes a first feeding mechanism 11. The assembled workpiece after mounting is sent into the first feeding mechanism 11 through the mounting device 16 in the forward movement process. The first feeding mechanism 11 conveys the assembled workpiece along the X-axis to the grasping position, and the mounting device 16 above the first feeding mechanism 11 also grasps the assembled workpiece and sends it into the subsequent curing conveying device 2.

[0109] Preferably, one or more groups of first feeding mechanisms 11 arranged in parallel can be adopted in the material taking device, and the mounting device 16 is driven by a three-axis driving mechanism to grasp the assembled workpieces on each group of first feeding mechanisms 11.

[0110] It should be noted that in this embodiment, when the first workpiece 3 is mounted on the second workpiece 4, the mounting positions of the second workpieces 4 on the tape 5 have been determined according to the assembly requirements. During subsequent cutting and dispensing processes, the second workpieces 4 in the second position will not change their positions. 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 on the first workpiece 3, this mounting process effectively improves the mounting efficiency and mounting accuracy.

[0111] The workpiece assembly production line of this embodiment can adapt to different workpiece mounting requirements. As long as the first workpiece 3 and the second workpiece 4 are in the corresponding mounting positions, the mounting of the workpieces can be completed, and it is not limited to the mounting of magnets and PINs in this embodiment.

[0112] The workpiece assembly method of the workpiece assembly production line in this embodiment includes the following steps:

[0113] S1. The first feeding mechanism 11 of the first group of workpiece mounting devices 1 transports the first workpiece 3 into the first position and adjusts the assembly angle of the first workpiece 3 at the same time.

[0114] S2. The second feeding mechanism 12 of the first group of workpiece mounting devices 1 transports the second workpiece 4 to the second position.

[0115] S3. The cutting device 14 of the first group of workpiece mounting devices 1 moves to the second position, cuts the second workpiece 4, and then leaves the second position.

[0116] S4. The dispensing device 15 of the first group of workpiece mounting devices 1 moves to the second position through the three-axis motion mechanism 13, dispenses the cut second workpiece 4, and then leaves the second position.

[0117] S5. Before the mounting device 16 grabs the first workpiece 3, it takes a picture of the position of the first workpiece 3 through the first vision module 17. The mounting device 16 grabs the first workpiece 3 located in the first position. Before the mounting device 16 enters the second position, it takes a picture of the assembly angle of the first workpiece 3 through the second vision module 18, and then transfers the first workpiece 3 to the second position, mounts the first workpiece 3 on the dispensed second workpiece 4, and then transports the mounted assembled workpiece to the next workpiece mounting device 1 through the first feeding mechanism 11.

[0118] S6. Repeat the above steps until the mounting of all assembly surfaces of the first workpiece 3 is completed. Then the assembled workpiece enters the material taking component through the flipping component. The material taking component transfers the assembled workpiece to the curing and conveying device 2, and the assembled workpiece is cured and conveyed to the discharging component.

[0119] Embodiment 2, asFigures 12 to 14 As shown, there are two sets of second feeding mechanisms 12 arranged along the Y-axis and two sets of dual-axis motion mechanisms 19, which directly correspond to each other, thus forming a dual-station layout.

[0120] 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 installed on the machine table; the z-axis motion mechanism 193 is installed on the y-axis motion mechanism 192. The cutting device 14 is installed on the z-axis motion mechanism 193. The dispensing device 15 is arranged on the back of the cutting device 14. The y-axis motion mechanism 192 and the z-axis motion mechanism 193 drive the cutting device 14 to the second position to cut the second workpiece 4. The cutting process is the same as that in the first embodiment. After cutting is completed, 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 for dispensing. The dispensing process is the same as that in the first embodiment. At the same time, the oppositely arranged cutting device 14 and dispensing device 15 have avoided each other in space. During the conversion process between the cutting process and the dispensing process, the stroke of the dual-axis motion mechanism 19 is very small, and the conversion speed is fast, while improving the processing efficiency.

[0121] Since the cutting process and the dispensing process require less time compared to the mounting process. Therefore, the cutting device 14 and the dispensing device 15 are driven by the dual-axis motion mechanism 19. When the cutting device 14 and the dispensing device 15 are working, the mounting device 16 can synchronously grasp the first workpiece 3, and the mounting process can be immediately carried out after the dispensing process is completed, improving the mounting efficiency. At this time, the cutting device 14 and the dispensing device 15 can cut and dispense the other set of second feeding mechanisms 12. After the mounting device 16 completes the mounting of the previous set, it can directly grasp another first workpiece 3 and then enter the other set of second feeding mechanisms 12 for mounting. There will be no mutual interference between the mounting device 16 and the cutting device 14 and the dispensing device 15 on different motion mechanisms, making the spatial arrangement better, and the mounting efficiency is also higher than that in the first embodiment.
