Description

Technical Field

[0001] The invention relates to the technical field of insulation treatment of a new energy motor stator assembly, and in particular to an automatic paint dripping device and a workstation. Background Art

[0002] In electric vehicles, the insulation treatment of the motor stator is an important process step. Insulating the motor stator can prevent the motor stator from directly contacting other metal parts and causing short circuits, which will affect the normal operation of the motor. It can also reduce energy loss and improve the working efficiency of the motor. It can also prevent corrosion of the motor stator and extend the life of the motor stator. The insulation treatment of the motor stator generally includes coating with insulating paint, installing insulating tubes, and setting insulating gaskets. Dripping paint is a way of applying insulating paint, which aims to evenly apply the insulating paint on the stator surface through the spot coating method to improve its electrical performance and durability.

[0003] Existing paint dripping methods:

[0004] Electric heating paint dripping method: This paint dripping process needs to be connected to the three-phase lead-out line of the stator assembly for power supply. During the paint dripping process, the paint is dripped while the power is on. The problems of this paint dripping method are: power is required when dripping paint. To achieve automatic docking of stator assemblies of different types, the docking power-on method needs to be changed to ensure stable power supply; the equipment structure is fixed, and generally the product structure needs to be modified according to the equipment structure to meet the requirements of co-line use; due to the power supply of the external cable, one side of the product cannot be dripped, affecting the filling effect of the insulating paint on some parts of the product; the equipment's outer dimensions are relatively large, which is not conducive to single-station single-machine loading operations.

[0005] Tunnel furnace heating and curing paint dripping method: This paint dripping process method supports the inner circle of the stator assembly and drives it to rotate through the chain inside the roller. After the paint dripping is completed, it enters the oven with the furnace for heating and curing. The problems of this paint dripping method are: because it runs continuously in the furnace, the product cannot present two postures, tilted and horizontal, when dripping paint; after dripping paint, the product gel curing can only be completed in the oven, and the gel effect in the oven is poor, the overflow of glue is serious, and the filling effect is poor; the station position in the equipment is fixed, and it can only be compatible with products of specific sizes, and the compatibility is poor; this paint dripping method is not convenient for small batch single station operation, and the flexibility is poor;

[0006] The above two paint dripping methods show that product model compatibility is not strong and the co-line compatibility production capacity is poor, which is not conducive to multi-variety compatible production and single-station automated operation. Summary of the invention

At the same time, the present invention can enable the product to drip paint in an inclined state, and after the tilt, paint can be dripped on the end face of the product, thereby meeting the paint dripping requirements of products with special structures.

[0045] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0046] An automatic paint dripping device, specifically, as Figures 1 to 3As shown, the present invention includes a shell 1, a self-rotating structure 2, a self-locking structure 3, a paint dripping rod 6, and an induction heating device 7. The shell 1 is a cavity structure with openings at both ends. The left and right ends of the shell 1 are provided with connecting parts, which are connected to the support rod 101. The shell 1 can swing with the connecting line of the two connecting parts as the axis. The lower end of the support rod 101 is connected to the base 102; the self-rotating structure 2 includes a self-rotating bearing 21, a self-rotating servo mechanism 22, and a transmission belt 23. The self-rotating bearing 21 is installed in the shell 1, and the outer ring of the self-rotating bearing 21 is fixedly connected to the shell 1. A plurality of fixed claws 51 are connected to the inner ring of the self-rotating bearing 21. The self-rotating servo mechanism 2 2 is fixedly connected to the housing 1, and the transmission belt 23 connects the output end of the self-rotating servo mechanism 22 and the inner ring of the self-rotating bearing 21; the self-locking structure 3 includes a self-locking servo mechanism 31 and a first transmission assembly 32, the self-locking servo mechanism 31 is fixedly connected to the housing 1, and its output end is connected to the first transmission assembly 32, the first transmission assembly 32 is connected to the inner ring of the self-rotating bearing 21, and its output end is connected to a movable claw 52; the paint dripping rod 6 is connected to the base 102, and a plurality of paint dripping nozzles 61 are connected to the paint dripping rod 6; the induction heating device 7 is connected to the base 102, and a heating part 71 is connected to the induction heating device 7, and the heating part 71 is located on the central axis of the self-rotating bearing 21.

[0047] When the rotation structure 2 is installed, the rotation bearing 21 is connected to the housing 1, the rotation servo mechanism 22 is fixed on the housing 1, the axis of the rotation servo mechanism 22 is perpendicular to the end face of the rotation bearing 21, and the transmission belt 23 sets the output end of the rotation servo mechanism 22 and the inner ring of the rotation bearing 21 together. When the output end of the rotation servo mechanism 22 rotates, it drives the transmission belt 23 to rotate, and the transmission belt 23 drives the inner ring of the rotation bearing 21 to rotate.

[0048] When the self-locking structure 3 is installed, the self-locking servo mechanism 31 is fixed on the housing 1, and its output end is connected to the first transmission component 32, and the axis of the self-locking servo mechanism 31 is parallel to the end face of the rotation bearing 21; the output end of the first transmission component 32 is connected to the movable claw 52, ​​and the axis of the output end of the first transmission component 32 is perpendicular to the inner ring wall of the rotation bearing 21.

[0049] During actual operation, the product is first placed on the fixed claw 51, and the self-locking servo mechanism 31 is started to drive the first transmission component 32 to work. The first transmission component 32 drives the movable claw 52 to move and locks the product between the fixed claw 51 and the movable claw 52; then the rotation servo mechanism 22 drives the transmission belt 23, and the transmission belt 23 drives the rotation bearing 21 to start rotating, driving the fixed claw 51, the movable claw 52 and the product therebetween to rotate, and at the same time, the paint dripping rod 6 starts to drip paint. In fact, the paint dripping rod 6 is connected to two paint dripping nozzles 61, and the two paint dripping nozzles 61 are respectively located at the front end and the rear end of the paint dripping device, and paint dripping work is performed on the two end faces of the product at the same time; after the paint dripping work is completed, the induction heating device 7 starts to work, and the heating part 71 is located on the central axis of the rotation bearing 21, and at the same time runs through the center line of the product, so that the product is fully heated, ensuring that all parts of the product are heated evenly, and improving the gel curing effect of the product paint dripping;

[0050] Furthermore, when the self-locking structure 3 drives the movable claw 52 to lock the product, the self-locking servo mechanism 31 first uses a high torque to drive the first transmission component 32 to push the movable claw 52, ​​so that the fixed claw 51 and the movable claw 52 quickly lock the product to prevent the product from loosening and falling; after locking the product, the self-locking servo mechanism 31 uses a low torque to drive the first transmission component 32 to move the movable claw 52 to further lock the product to prevent excessive torque from damaging the product.

[0051] When replacing products of different sizes, the fixed claws 51 and the movable claws 52 can be disassembled and replaced with fixed claws 51 and movable claws 52 of corresponding sizes. The larger the product size, the fixed claws 51 and movable claws 52 with smaller thickness and larger curvature should be replaced; the smaller the product size, the fixed claws 51 and movable claws 52 with larger thickness and smaller curvature should be replaced.

[0052] When dripping paint on special-shaped products, the shell 1 swings with the line connecting the two connecting parts as the axis, so that the end face of the product is in an inclined state, which makes it easier for the paint dripping nozzle 61 to drip paint on the end face of the product to meet the paint dripping requirements of the special-shaped products.

[0053] In some embodiments, the first transmission assembly 32 is optimized, such as Figure 6 As shown, in this embodiment, the first transmission component 32 includes a bevel gear 32a, a universal joint 32b, a worm 32c, a turbine 32d and a threaded rod 32e. The bevel gear 32a is connected to the output end of the self-locking servo mechanism 31; the conical tooth pattern on the shaft wall of the universal joint 32b is vertically meshed with the conical tooth pattern of the bevel gear 32a, and the end of the universal joint 32b is connected to the worm 32c; the worm 32c is meshed with the turbine 32d; a threaded hole is provided on the turbine 32d, and the threaded rod 32e passes through the threaded hole to be connected to the movable claw 52.

[0054] During actual operation, the self-locking servo mechanism 31 drives the bevel gear 32a to rotate, the bevel gear 32a drives the universal joint 32b to rotate, the universal joint 32b drives the worm 32c to rotate, the worm 32c drives the turbine 32d to rotate, the turbine 32d drives the threaded rod 32e to rotate and move up and down relative to the turbine 32d, and the turbine 32d drives the movable claw 52 to move up and down to realize the locking function of the product.

[0055] In some embodiments, the automatic paint dripping device is optimized, such as Figure 1 , 2 As shown in Figures 3 and 7, the automatic paint dripping device in this embodiment also includes a swinging structure 4, which includes a swinging servo mechanism 41 and a second transmission component 42. The swinging servo mechanism 41 is fixedly connected to the base 102, and a slide rail is provided on the swinging servo mechanism 41. The second transmission component 42 is slidably connected to the slide rail, and the second transmission component 42 is connected to the bottom of the shell 1.

[0056] Furthermore, the second transmission assembly 42 includes a slide plate 42a, a slider 42b, and a connecting plate 42c. A gripper is connected below the slide plate 42a, and the gripper can grasp the slide rail on the swing servo mechanism 41 and slide along the slide rail; the slide plate 42a and the slider 42b are connected by bolts; one end of the connecting plate 42c is fixedly connected to a slide groove, and the slide plate 42a can slide up and down in the slide groove. The other end of the connecting plate 42c is connected to the bottom of the shell 1 by bolts, and the two can rotate relative to each other around the connecting bolts.

[0057] When the swing structure 4 is installed, the swing servo mechanism 41 is fixedly connected to the base 102, and its axis is perpendicular to the end face of the shell 1; the slide plate 42a can slide on the slide rail along the axial direction of the swing servo mechanism 41; the slider 42b is vertically bolted to the slide plate 42a; the connecting plate 42c is an L-shaped plate, one end of which is fixedly connected to the shell 1, and the other end is connected to a slide groove, and the slide groove is embedded with the slider 42b.

[0058] During actual operation, the swing servo mechanism 41 drives the slide plate 42a to move forward and backward on the slide rail. The slide plate 42a moves forward and backward while driving the slider 42b to move forward and backward. When the slider 42b moves forward and backward, it drives the connecting plate 42c and the bottom of the shell 1 to move forward and backward. When the bottom of the shell 1 moves forward and backward, it forces the shell 1 to rotate around the line connecting its two connecting parts as the axis. When the shell 1 rotates, its bottom will lift upward, thereby driving the connecting plate 42c to lift upward. The connecting plate 42c rotates relative to the bottom of the shell 1 and remains parallel to the slider 42b. At this time, the slide groove of the connecting plate 42c will move upward relative to the slider 42b, completing the swinging work of the shell 1.

[0059] In some embodiments, the automatic paint dripping device is optimized, such as Figure 3As shown, the automatic paint dripping device in this embodiment further includes a temperature sensing monitoring device 8 , and the temperature sensing monitoring device 8 is connected to the end surface of the shell 1 .

[0060] In actual operation, the temperature sensing monitoring device 8 is used to monitor the temperature of the product during gel curing in real time. When the product temperature is too high, the power of the heating part will be reduced; when the product temperature is too low, the power of the heating part will be reduced to ensure that the product is in a stable heating environment.

[0061] In some embodiments, Figures 1 to 3 As shown, the above-mentioned automatic paint dripping device is optimized. In this embodiment, the automatic paint dripping device also includes a paint dripping collection bucket 9, which includes a bucket surface 91 and a connecting platform 92. The bucket surface 91 is connected to the connecting platform 92, and the connecting platform 92 is connected to the end face of the shell 1.

[0062] In fact, the automatic paint dripping device comprises two paint dripping collecting hoppers 9, the paint dripping collecting hopper 9 located at the front of the automatic paint dripping device is as shown in FIG. Figure 1 , 2 As shown, the bucket surface 91 has the same arc radius as the rotating bearing 21 and is located in front of the rotating bearing 2. The connecting platform 92 is connected to the base 102. The paint dripping collection bucket 9 located at the back of the automatic paint dripping device is as shown in FIG. Figure 1 , 3 As shown, the arc radius of the bucket surface 91 is slightly smaller than the arc radius of the arc of the rotating bearing 21, is located above the inner ring of the rotating bearing 2, and extends a distance into the rotating bearing 21, and the connecting platform 92 is connected to the base 102; in actual operation, the paint dripping collection bucket 9 can recover the dripping paint liquid that overflows and leaks during the paint dripping process, which can improve the utilization rate of the dripping paint liquid and reduce costs.

[0063] An automatic paint dripping workstation, specifically, as Figure 8 , 9 As shown, the present invention includes a paint dripping device 100, a material buffer table 200 and a transfer rail clamping device 300. A starting station and at least one paint dripping station are arranged on one side of the transfer rail clamping device 300. The transfer rail clamping device 300 is used to move the product between the starting station and the paint dripping station; the material buffer table 200 is located at the starting station and is used to temporarily store the products to be processed or the processed products; the paint dripping device 100 is any of the automatic paint dripping devices described above, and the paint dripping device 100 is located at the paint dripping station.

[0064] During actual operation, the product to be processed is first placed on the material buffer table 200; then the product to be processed is moved to the paint dripping device 100 through the transfer rail clamping device 300, and the product is placed on the fixed claw 51; the self-locking structure 3 drives the movable claw 52 to move, and cooperates with the fixed claw 51 to clamp the product to be processed; the self-rotating structure 2 drives the fixed claw 51, the movable claw 52 and the product to rotate, and the paint dripping nozzle 61 drips paint on the product, and the shell 1 swings to a preset angle with the connecting line of the two connecting parts as the axis, so that the product remains in an inclined state, and the end surface of the product is dripped After the paint dripping is completed, the induction heating device 7 is started to gel-cure the insulating paint on the product. During this period, the temperature sensing monitoring device 8 monitors the temperature of the product in real time. When the temperature is too high, the induction heating device 7 is controlled to reduce the output power to reduce the temperature of the product surface. When the temperature is too low, the induction heating device 7 is controlled to increase the output power to increase the temperature of the product surface. After the paint dripping is completed, the product is moved from the paint dripping device 100 to the material buffer table 200 through the transplanting rail clamping device 300; finally, the processed product is transferred to the next workstation manually or by a robot.

[0065] In some embodiments, the material buffer station 200 is optimized. Figure 8 As shown, in this embodiment, the material buffer station 200 includes a loading buffer area 201 and a unloading buffer area 202. The loading buffer area 201 is used to temporarily store products to be processed, and the unloading buffer area 202 is used to temporarily store processed products.

[0066] Specifically, before the product is dripped with paint, the product to be processed is first placed on the loading buffer area 201, and then the product to be processed is moved from the loading buffer area 201 to the paint dripping device 100 for dripping paint processing by the transfer rail clamping device 300; when the product processing is completed, the processed product is moved from the paint dripping device 100 to the unloading buffer area 202 by the transfer rail clamping device 300, and finally the processed product is transferred to the next station manually or by a robot. Placing the products to be processed and the processed products in different areas can effectively avoid the situation where the products are repeatedly processed or the products are transferred to the next station without being processed.

[0067] In some embodiments, the above-mentioned automatic paint dripping workstation is optimized, such as Figure 8 As shown, in this embodiment, the automatic paint dripping workstation can be equipped with multiple paint dripping devices 100 to work simultaneously, and the multiple paint dripping devices 100 are respectively arranged on multiple paint dripping stations.

[0068] In actual work, mass production is carried out by translating and replicating multiple paint dripping devices 100. The same model of products can be mass-produced, and different models of products can also be processed and produced at the same time; each paint dripping device 100 is independent of each other, and the production lines of each paint dripping device 100 are connected in series by transplanting the ground rail clamping device 300, which greatly improves work efficiency.

[0069] In some embodiments, the above-mentioned transplanting rail clamping device 300 is optimized, such as Figure 7 , 8 As shown, in this embodiment, two parallel guide rails are arranged below the transplanting ground rail clamping device 300, and the two guide rails are connected by a connecting rod. The guide rails of the transplanting ground rail clamping device 300 can be extended according to the number of paint dripping devices 100.

[0070] Specifically, it is known that the positions of the paint dripping device 100 and the material buffer table 200 are fixed. A complete workflow requires a device for transporting products between the paint dripping device 100 and the material buffer table 200, namely, a transplanting ground rail clamping device 300. By setting two parallel guide rails under the transplanting ground rail clamping device 300 and fixing the movement trajectory of the transplanting ground rail clamping device 300, it can be ensured that the position of the product in the paint dripping device 100 can be kept consistent each time.

[0071] In some embodiments, Figure 1-3 As shown, the above-mentioned automatic paint dripping device is optimized and further includes an HMI control panel 400 , wherein the HMI control panel 400 is mainly used to control parameter settings and servo mechanism programs of the paint dripping device 100 .

[0072] In fact, when it is necessary to process products with different structures, it is not only necessary to replace the fixed claws 51 and the movable claws 52 of different sizes, but also necessary to adjust the rotation speed and swing angle of the shell 1 through the HMI control panel 400 to adapt to products with different structures.

[0073] Specifically, when the product is subjected to the paint dripping process, the product to be processed is first placed in the loading buffer area 201 on the material buffer table 200; then the product to be processed is moved to the paint dripping device 100 by the transfer rail clamping device 300, and the product is placed on the fixed claw 51; the HMI control panel 400 is operated to drive the movable claw 52 to move through the self-locking structure 3, and cooperate with the fixed claw 51 to clamp the product to be processed; the paint dripping nozzle 61 is started to drip paint on the product to be processed; during this period, the housing 1 is swung to the angle preset by the HMI control panel 400 with the connecting line of the two connecting parts as the axis, so that the product maintains an inclined posture, Paint is dripped on the end face of the product; after the paint dripping is completed, the induction heating device 7 is started to gel-cure the insulating paint on the product; during this period, the temperature sensing monitoring device 8 monitors the temperature of the product in real time. When the temperature is too high, the induction heating device 7 is controlled to reduce the output power and reduce the temperature of the product surface. When the temperature is too low, the induction heating device 7 is controlled to increase the output power and increase the temperature of the product surface; after the processing is completed, the processed product is moved from the paint dripping device 100 to the unloading buffer area 202 on the material buffer table 200 by the transplanting ground rail clamping device 300; finally, the processed product is transferred to the next workstation manually or by a robot.
