Description

Technical Field

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

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

[0003] During the production of chips, the magnets need to be precisely connected to the PINs (pins), because 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: dispensing glue on the mounting position of the mounting surface of the magnet, and then mounting the PIN to the corresponding mounting position after dispensing glue.

[0004] In the prior art, in addition to the glue dispensing process, which can use glue dispensing equipment to dispense glue on magnets, the mounting process usually uses manual mounting. However, manual operation is difficult to ensure 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 volume of the PIN is relatively small, the mounting position of the magnet and the PIN will deviate during the mounting process. At the same time, manual assembly is slow and inefficient. In a large-scale production environment, manual assembly will become a bottleneck of the production line. Summary of the invention

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Embodiment 1, as Figures 1 to 11 As shown, a workpiece assembly production line includes a plurality of workpiece placement devices 1 and a curing conveying device 2. The first workpiece 3 and the second workpiece 4 are placed in the workpiece placement device 1, and the assembled workpiece after placement enters the next workpiece placement device 1 to perform placement on another assembly surface of the second workpiece 4, until all assembly surfaces of the first workpiece 3 are placed, and the assembled workpiece after placement is cured during the conveying process by the curing conveying device 2. The assembled workpiece refers to a workpiece formed after the first workpiece 3 and the second workpiece 4 are placed once or multiple times.

[0046] In this embodiment, the first workpiece 3 is a magnet, and the second workpiece 4 is an inductor PIN (pin). The magnet generally has four faces that need inductor PINs, and each face needs to be mounted with a different number of inductor PINs according to product design requirements. There are slots corresponding to the inductor PINs on each face of the magnet, and the slots correspond to the mounting faces of a single inductor PIN. The mounted workpieces are as follows: Fig.11 shown.

[0047] The workpiece placement device 1 includes a first loading mechanism 11 and a second loading mechanism 12 .

[0048] Specifically, the first loading mechanism 11 conveys the first workpiece 3 to the first position and adjusts the orientation of the assembly surface of the first workpiece 3. The first loading mechanism includes a bearing assembly 111. The first workpiece 3 is placed on the bearing assembly 111, and the bearing assembly 111 moves along the X-axis to convey the first workpiece 3 to the first position (such as Figure 4 As shown by arrow a in the figure, the bearing assembly 111 is mounted on the linear motor module 1112 to achieve movement along X. The first position here refers to the position where the magnet is grasped by the mounting device 16, and the vibration plate transports the magnet to this position for the mounting device 16 to grasp the magnet.

[0049] Furthermore, the bearing assembly 111 can also move along the Z-axis and transport the first workpiece 3 to the flip assembly 112. The flip assembly 112 clamps and flips the first workpiece 3. The bearing assembly 111 and the flip assembly 112 are both arranged on a base 1111, and the base 1111 is connected to the linear motor module 1112 and moves along the X-axis. The bearing assembly 111 has a support 1113 for placing the workpiece, and the support 1113 is driven to rise and fall by the Z-axis slide cylinder 1114. The clamping part 1121 is driven by the Y-axis slide cylinder 1123, and the workpiece is clamped by the clamping head 1124 at the upper end. The clamping head 1124 is driven to rotate by the rotary cylinder 1122 to flip the second workpiece 4.

[0050] The first workpiece 3 is lifted by the bearing assembly 111 to the flip assembly 112. The flip assembly 112 includes two symmetrically arranged clamping parts 1121, which are mounted on the Y-axis slide cylinder 1123. The clamping parts 1121 can be relatively close to or away from each other along the Y-axis, and a clamping head 1124 is rotatably connected to the clamping part 1121. A rotating cylinder 1122 is provided on one of the clamping parts 1121, and the rotating 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 rotating cylinder 1122, and the connecting shaft translates along the Y-axis in the output end, and is driven by the output end to rotate around the Y-axis. A connecting hole is provided at the output end, and the connecting shaft can translate along the Y-axis in the connecting hole, and the connecting shaft is circumferentially limited by the connecting hole in the Y-axis. Through the cooperation of the connecting shaft and the connecting hole, the circumferential limit of the connecting shaft is realized, and it can be ensured that the rotating 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 in the connecting hole to ensure the freedom of movement on the Y axis. Of course, a linear bearing can also be used between the rotating cylinder 1122 and the connecting shaft to achieve the same effect.

[0051] When the supporting assembly 111 lifts the first workpiece 3 upward to the flipping assembly 112, the clamping portion 1121 is driven by the Y-axis slide cylinder 1123 and moves toward the first workpiece 3, and the clamping head 1124 on the clamping portion 1121 clamps the first workpiece 3, and then the rotating cylinder 1122 drives the clamping head 1124 to rotate to flip the first workpiece 3 and adjust the assembly surface of the first workpiece 3.

[0052] Of course, the first feeding mechanism 11 can also use a vibration plate, which can flip the magnet during the process of conveying the magnet, thereby adjusting the assembly angle of the magnet. The assembly angle here refers to the end face of the magnet to be mounted, ensuring that the required assembly surface of the magnet is facing downward.

[0053] Specifically, the second loading mechanism 12 conveys at least one second workpiece 4 to the second position (eg Figure 7 The second feeding mechanism 12 adopts a cutting feeding mechanism, including a material tray 121 for conveying the material belt 5. The second workpiece 4 and the material belt 5 are integrated, and the material belt 5 is transported by a ratchet. There are multiple second workpieces 4 on the material belt 5, and the number of the second workpieces 4 is consistent with the number of slots to be mounted on the assembly surface of the first workpiece 3. Since there may be different numbers of second workpieces 4 at the second position according to the mounting requirements of the first workpiece 3, the second position is the position where all the second workpieces 4 enter to be cut and glued.

[0054] Furthermore, there are corresponding positioning holes on both sides of the material belt 5, and the second loading mechanism 12 also includes a rotatable feeding ratchet 122. A plurality of positioning columns 123 are provided on the circumference of the feeding ratchet 122. When the feeding ratchet 122 rotates, the positioning columns 123 will enter the positioning holes. As the feeding ratchet 122 rotates, the material belt 5 will be pushed forward, thereby ensuring that the second workpiece 4 on the material belt 5 can be accurately moved to the second position.

[0055] Furthermore, in this embodiment, the number of the second feeding mechanism 12 is one.

[0056] 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.

[0057] 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 platform, 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 .

[0058] Specifically, the cutting device 14 is arranged at the leftmost side of the mounting plate. The cutting device 14 comprises a cutting cylinder 141, a cutting head 142 and a positioning pin 143. The cutting head 142 is a profiling head.

[0059] A cutting base 144 is provided below the cutting device 14. The cutting base 144 is driven to rise and fall by a cylinder 145. 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, thereby ensuring effective adsorption of the second workpiece 4 and ensuring that the second workpiece 4 does not move during the cutting and dispensing process. When the mounting is completed, the vacuum adsorption is stopped, and the second workpiece 4 can follow the first workpiece 3 to leave the second position.

[0060] The cutting device 14 is driven by the x-axis motion mechanism 191 to move to just 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 positioning plate below to achieve position correction, and then the cutting cylinder 141 drives the cutting head 142 downward, and the cutting head 142 cuts the second workpiece 4 from the material strip 5.

[0061] Specifically, the material strip 5 is divided into a plurality of 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 a plurality of second workpieces 4, the corresponding block on the material strip 5 enters the second position, and then the cutting head 142 cuts all the second workpieces 4 from the material strip 5 at one time, and then the glue dispensing operation is performed. After the cutting is completed, the cutting device 14 is driven to leave 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 process.

[0062] Specifically, the dispensing device 15, the mounting device 16 and the first visual module 17 are installed on the three-axis motion mechanism 13. The dispensing device 15 and the mounting device 16 are arranged opposite to each other, avoiding each other in space, and the motion stroke of the three-axis motion mechanism 13 can be reduced when switching between the dispensing process and the mounting process.

[0063] After the cutting device 14 completes cutting, the X-axis motion mechanism 132 and the Y-axis motion mechanism 131 drive the glue dispensing device 15 to enter above the second position, and then the Z-axis motion mechanism 133 moves the glue dispensing device 15 downward to the second workpiece 4 for glue dispensing, and glue is dispensed on the mounting surface of each second workpiece 4. After completing the glue dispensing of a second workpiece 4, the glue dispensing device 15 only needs to move along the arrangement direction of the second workpiece 4, and then repeat the above steps to complete the glue dispensing operation on all the cut second workpieces 4 in turn, thereby greatly improving the glue dispensing efficiency.

[0064] Specifically, the mounting device 16 includes a clamp 161. The clamp 161 can be a flexible clamp or a cylinder clamp. A U-axis motor 162 is connected above the clamp 161, and the angle of the clamp 161 can be adjusted by the U-axis motor 162. After the dispensing is completed, the Z-axis motion mechanism 133 moves the dispensing device 15 upward to leave the second position, and then drives the mounting device 16 to reach above the first position through the X-axis motion mechanism 132 and the Y-axis motion mechanism 131. The Z-axis motion mechanism 133 drives the mounting device 16 downward and grabs the first workpiece 3 at the first position. Before the first workpiece 3 is transferred to the second position, the first workpiece 3 will be photographed by the second visual module 18. If there is a deviation in the assembly angle of the first workpiece 3, the U-axis motor 162 drives the clamp 161 to be fine-tuned on the U-axis to ensure the subsequent mounting accuracy. Then, the X-axis motion mechanism 132 and the Y-axis motion mechanism 131 drive the mounting device 16 to move above the second position, and the Z-axis motion mechanism 133 drives the mounting device 16 downward to move the first workpiece 3 into the second position, and mounts the second workpiece 4 on the assembly surface of the first workpiece 3.

[0065] Furthermore, the first vision module 17 is arranged on the right side of the mounting device 16. Before the mounting device 16 grabs 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 and complete the accurate mounting steps.

[0066] The cutting device 14 and the glue dispensing device 15 are arranged on different motion mechanisms, so the time of the cutting process and the glue dispensing process is shortened and the production efficiency is improved. At the same time, the cutting device 14 is arranged on the two-axis motion mechanism 19, and the glue dispensing device 15 and the mounting device 16 are arranged on the three-axis motion mechanism 13, so that the overall space utilization rate is higher, each device is easier to avoid in space, and the layout between the devices is more compact.

[0067] Preferably, when the first workpiece 3 and the second workpiece 4 are mounted, a pre-curing process is used to firmly mount the first workpiece 3 and the second workpiece 4 to prevent the second workpiece 4 from falling off from the first workpiece 3 during subsequent movement. According to the requirements of the dispensing process, a UV lamp or a heating curing component can be provided on the mounting device 16 or the second feeding mechanism 12.

[0068] Specifically, after completing the mounting of one assembly surface of the first workpiece 3, the mounting device 16 places the assembled workpiece on the first loading mechanism 11 of the next workpiece mounting device 1, feeds the assembled workpiece into the next workpiece mounting device 1, and repeats the above steps until the mounting of all assembly surfaces of the first workpiece 3 is completed.

[0069] Furthermore, the material picking device also includes a first loading mechanism 11. The assembled workpiece that has completed the mounting is sent to the first loading mechanism 11 through the mounting device 16 of the forward moving process. The first loading mechanism 11 transports the assembled workpiece along the X-axis to the grabbing position. The mounting device 16 above the first loading mechanism 11 also grabs the assembled workpiece and sends it to the curing conveying device 2 at the rear.

[0070] Preferably, the material picking device may use one or more groups of first feeding mechanisms 11 arranged in parallel, and the mounting device 16 is driven by a three-axis driving mechanism to grab the assembled workpieces on each group of first feeding mechanisms 11.

[0071] It should be noted that, in the present embodiment, the first workpiece 3 is mounted on the second workpiece 4. The second workpieces 4 located on the material strip 5 have already determined the mounting positions of the respective second workpieces 4 according to the assembly requirements. During the subsequent cutting and gluing processes, the second workpieces 4 located at 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 at 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.

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

[0073] The workpiece assembly method of the workpiece assembly production line of this embodiment includes the following steps: S1. The first loading mechanism 11 of the first group of workpiece placement devices 1 transports the first workpiece 3 to the first position and adjusts the assembly angle of the first workpiece 3 at the same time.

[0074] S2. The second loading mechanism 12 of the first group of workpiece placement devices 1 transports the second workpiece 4 to the second position.

[0075] 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.

[0076] S4. The glue 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 glue to the cut second workpiece 4, and then leaves the second position.

[0077] S5. Before grabbing the first workpiece 3, the mounting device 16 uses the first vision module 17 to photograph the position of the first workpiece 3, and the mounting device 16 moves to grab the first workpiece 3 at the first position. Before entering the second position, the mounting device 16 uses the second vision module 18 to photograph the assembly angle of the first workpiece 3, and then transfers the first workpiece 3 to the second position, mounts the first workpiece 3 and the second workpiece 4 after gluing, and then transports the assembled workpieces after mounting to the next workpiece mounting device 1 through the first loading mechanism 11.

[0078] S6. Repeat the above steps until all assembly surfaces of the first workpiece 3 are mounted, and then the assembled workpiece enters the material picking component through the flipping component, and the material picking component transfers the assembled workpiece to the curing and conveying device 2, and the assembled workpiece is cured and conveyed to the discharging component.

[0079] Embodiment 2, as Figure 12 to Figure 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, thereby forming a double-station layout.

[0080] The dual-axis motion mechanism 19 includes: a y-axis motion mechanism 192 and a z-axis motion mechanism 193, wherein the y-axis motion mechanism 192 is mounted on the machine platform; and the z-axis motion mechanism 193 is mounted on the y-axis motion mechanism 192. The cutting device 14 is mounted on the z-axis motion mechanism 193. The glue 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, and the cutting process is the same as that of the first embodiment. After the cutting is completed, the z-axis motion mechanism 193 drives the cutting device 14 to leave the second position, and then the y-axis motion mechanism 192 drives the glue dispensing device 15 to the second position for glue dispensing, and the glue dispensing process is the same as that of the first embodiment. At the same time, the cutting device 14 and the glue dispensing device 15, which are arranged opposite to each other, have been spatially avoided from each other, and the dual-axis motion mechanism 19 has a small stroke during the conversion process between the cutting process and the glue dispensing process, and the conversion speed is fast, while the processing efficiency is improved.

[0081] Since the cutting process and the gluing process require less time than the mounting process, the cutting device 14 and the gluing device 15 are driven by a dual-axis motion mechanism 19. When the cutting device 14 and the gluing device 15 are working, the mounting device 16 can synchronously grab the first workpiece 3, and the mounting process can be performed immediately after the gluing process is completed, thereby improving the mounting efficiency. At this time, the cutting device 14 and the gluing device 15 can cut and glue another group of second feeding mechanisms 12. After the mounting device 16 completes the previous group of mounting, it can directly grab another first workpiece 3 and then enter another group 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 gluing device 15 on different motion mechanisms, which makes the spatial arrangement better and the mounting efficiency is higher than that of the first embodiment.
