Description

Technical Field

[0001] The invention relates to the field of paint dripping equipment, in particular to a double-station paint dripping equipment. Background Art

[0002] The prior art paint dripping equipment generally only has a single paint dripping station, and a heating device can be configured for the paint dripping station. In order to improve the paint dripping efficiency of a single paint dripping equipment, it is considered to set up a double paint dripping station, taking into account the heating requirements, and integrating two single paint dripping station paint dripping equipment into one, the overall volume of which is slightly smaller than the sum of the volumes of the original two single paint dripping station paint dripping equipment, but such a combination does not reflect the obvious advantages of the double station paint dripping equipment.

[0003] If the dual-station integrated design space is taken into consideration, there is a problem of inconvenience in designing a heating device. For example, CN214440601 U discloses a dual-station paint dripping device, which can improve the efficiency of stator paint dripping by dual-station setting. It has tracks symmetrically arranged on the frame, and movable plates are arranged on the tracks. A driving device for driving the movable plates to move is arranged on one side of the track. A clamp assembly is arranged on the movable plate. A paint dripping assembly is arranged above both sides of the track inside the frame, and a transplanting device is arranged at the bottom of the track inside the frame. A lifting device is arranged on one side of the transplanting device inside the frame. When in use, the stator is placed on the transplanting device, and the stator is transported to the lifting device by the transplanting device. The lifting device lifts the stator to the track, and the stator is grabbed and fixed by the clamp assembly. The movable plate moves to the paint dripping assembly, and the paint dripping assembly drips paint on the stator on the clamp assembly. This kind of dual-station paint dripping device is not convenient for heating when dripping paint, especially the heating device cannot be extended into the interior of the stator product for heating. If a heating device is configured for the double workstation, it is only possible to set up heating capacity outside the double workstation, which is equivalent to setting up a heating structure for the entire double workstation.

[0004] Moreover, in the prior art, the heating capacity / efficiency of the heating device configured on the same paint dripping equipment is usually fixed and single, and different heating times are required for different products. In particular, for the heating device configured on the paint dripping equipment, it heats when dripping paint, and the stator products required for dripping paint are different, and their corresponding requirements for heating capacity are also different. If a dedicated paint dripping device is used for each stator product, it will inevitably bring about a series of problems such as more equipment, high purchase cost, and troublesome equipment storage and management. Therefore, the industry generally uses the same paint dripping equipment to accommodate the paint dripping operations of different stator products, and it is difficult to take into account the respective ideal heating capacity requirements of different stator products, which limits the further improvement of the paint dripping quality.

[0005] Also, as the paint dripping equipment is upgraded from a three-dropper type to a four-dropper type, it is impossible to set up an automatic rate measurement structure on the paint dripping equipment. When the paint rate needs to be measured, the traditional manual testing method has to be used, that is: place the paint liquid collection cup under the paint dripping needle to collect the paint liquid and then put it on the electronic scale for weighing, which is troublesome to operate.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0007] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a double-station paint dripping equipment, which realizes the convenience of heating under the premise of double paint dripping stations, and can select different heating units according to actual heating needs to meet the paint dripping heating requirements of different stator products, which is beneficial to improving the paint dripping quality, and is convenient for weighing and speed measurement.

[0039] A double-station paint dripping equipment includes a machine platform 10, two stator paint dripping stations 100 arranged side by side along the X-axis on the machine platform 10, and a mobile heating device 200. The stator paint dripping station 100 is provided with a stator clamping mechanism and a paint dripping mechanism 30, and an entrance and exit are provided on the front side of the stator paint dripping station 100 corresponding to the clamping opening of the stator clamping mechanism, and an automatic weighing mechanism 40 is provided between the entrances and exits of the two stator paint dripping stations 100, and the automatic weighing mechanism 40 includes a paint liquid collection cup 41 and a weighing platform 42, and the paint liquid collection cup 41 is located on the weighing platform 42, and the paint dripping mechanism 30 can selectively drip paint toward the paint liquid collection cup 41 to measure the speed or drip paint on the stator product 60 toward the entrance and exit.

[0040] The machine 10 is provided with a stand 20, and the stand 20 has a stator positioning hole 102 penetrating along the Y axis; two stator positioning holes 102 are provided and arranged side by side along the X axis, and a set of the paint dripping mechanism 30 is provided corresponding to each stator positioning hole 102. The stator paint dripping station 100 is provided corresponding to the stand 20, and here, one stator paint dripping station 100 is provided on one stand 20. The inlet and outlet are provided corresponding to the front end opening of the stator positioning hole 102.

[0041] The paint dripping mechanism 30 is arranged on the stand 20, and the paint dripping mechanism 30 includes a first side paint dripping assembly 31, a second side paint dripping assembly 32 and an XYZ three-axis driving device; the first side paint dripping assembly 31 and the second side paint dripping assembly 32 are respectively located on two opposite sides of the stand 20 and are respectively arranged at the two end openings of the stator positioning hole 102; the automatic weighing mechanism 40 is respectively arranged on two opposite sides of the stand 20 and is arranged at the two end openings of the stator positioning hole 102 deviated from the stator positioning hole 102 along the X-axis direction. Usually, the weighing platform 42 has an electronic balance inside. The electronic balance is connected to the PLC of the paint dripping equipment. The paint dripping rate can be calculated using the paint liquid weight fed back by the electronic balance and the set time. The PLC can be connected to control the first side paint dripping component 31 and the second side paint dripping component 32. Therefore, the speed of the paint supply screw pump can be adjusted according to the measured paint dripping rate, and then the paint dripping rate can be adjusted; the XYZ three-axis drive device drives the first side paint dripping component 31 and the second side paint dripping component 32 to move along the XYZ three-axis direction to selectively drip paint toward the paint liquid collection cup 41 for speed measurement or drip paint toward the stator product 60.

[0042] Specifically, the XYZ three-axis driving device includes an X-axis paint dripping translation driving device 33, a first Y-axis paint dripping translation driving device 34, a second Y-axis paint dripping translation driving device 35, a first Z-axis paint dripping lifting driving device 36 and a second Z-axis paint dripping lifting driving device 37, and the X-axis paint dripping translation driving device 33 is arranged on the top of the stand 20. The first Z-axis paint dripping lifting drive device 36 drives the first side paint dripping assembly 31 to move along the Z-axis, the second Z-axis paint dripping lifting drive device 37 drives the second side paint dripping assembly 32 to move along the Z-axis, the first Y-axis paint dripping translation drive device 34 drives the first side paint dripping assembly 31 and the first Z-axis paint dripping lifting drive device 36 to move along the Y-axis, the second Y-axis paint dripping translation drive device 35 drives the second side paint dripping assembly 32 and the second Z-axis paint dripping lifting drive device 37 to move along the Y-axis, and the X-axis paint dripping translation drive device 33 drives the first Y-axis paint dripping translation drive device 34 and the second Y-axis paint dripping translation drive device 35 to move along the X-axis together.

[0043] The automatic weighing mechanism 40 is located between the corresponding two end openings of the two stator positioning holes 102, so that the automatic weighing mechanism 40 on the same side provides the paint dripping speed measurement for the corresponding first side paint dripping assembly 31 or second side paint dripping assembly 32 of the paint dripping mechanism 30 of the two stator positioning holes 102. The stand 20 is provided with a turntable frame 39 and a deflection swing driving device 391, the deflection swing driving device 391 drives the turntable frame 39 to rotate and swing around the X-axis, the turntable frame 39 is provided with a turntable 38, the turntable 38 rotates around the Y-axis relative to the turntable frame 39, and the turntable 38 is provided with a stator clamping mechanism, the clamping claws of the stator clamping mechanism surround and form the stator positioning hole 102, so as to achieve five-axis paint dripping. The stand 20 is separately arranged corresponding to each stator positioning hole 102, the yaw drive device 391 is arranged on the far side of the two stands 20 in the X-axis direction, and the automatic weighing mechanism 40 is located on the adjacent side of the two stands 20 in the X-axis direction, which further makes its structural arrangement compact and reasonable. In this embodiment, a bottom plate portion 201 is arranged below each stand 20, and the bottom plate portion 201 is located below the turntable frame 39 and exceeds the two opposite sides of the stand 20, that is, it exceeds the two end outlets of the stator positioning hole 102 along the Y-axis direction. The automatic weighing mechanism 40 is located between the two bottom plates 201. In this way, through the structural design of the machine 10 and the stand 20, the paint dripping mechanism 30, and the automatic weighing mechanism 40 arranged on the machine 10, the automatic weighing mechanism 40 is integrated on the machine 10, and the first side paint dripping component 31, the second side paint dripping component 32 and the XYZ three-axis driving device of the paint dripping mechanism 30 are cleverly utilized to meet the paint dripping speed measurement and the automatic displacement action of dripping paint on the stator product. The weighing speed measurement is convenient, and the structural design is compact and reasonable. It realizes four-dropper paint dripping and automatic weighing in a limited space. In addition, it is suitable for horizontal feeding and discharging. Compared with the paint dripping equipment that feeds from the bottom to the top, the height of the fuselage equipment is reduced, which is conducive to maintenance and can be compatible with the paint dripping operation of more stator products.

[0044] The mobile heating device 200 is located at the front side of the stator paint dripping station, and the mobile heating device includes an X-axis moving mechanism 23, a translation seat 11, a first Y-axis moving mechanism 21, a second Y-axis moving mechanism 22, a first heating unit 201 and a second heating unit 202. The X-axis moving mechanism 23 drives the translation seat 11 to move along the X-axis, so that the first heating unit 201 and the second heating unit 202 can be selectively set corresponding to the entrance and exit of any stator paint dripping station, and the stator product is loaded and unloaded from the entrance and exit. When loading and unloading, the first heating unit 201 and the second heating unit 202 of the mobile heating device avoid the entrance and exit. The first Y-axis moving mechanism 21 and the second Y-axis moving mechanism 22 are arranged on the translation seat 11. The first Y-axis moving mechanism 21 drives the first heating unit 201 to move along the Y-axis direction to drive the first heating unit 201 to move along the Y-axis direction so that it can extend into the inlet and outlet to heat the stator product. The second Y-axis moving mechanism 22 drives the second heating unit 202 to move along the Y-axis direction so that it can extend into the inlet and outlet to heat the stator product. In this embodiment, the X-axis moving mechanism 23 is a first motor linear module, which includes a first motor, an X-axis lead screw, a first slide seat, and an X-axis guide rail. The first motor drives the X-axis lead screw to rotate, and the first slide seat is adapted to the X-axis thread phase through an internal threaded hole, and the first slide seat slides along the X-axis guide rail. The first Y-axis moving mechanism 2121 and the second Y-axis moving mechanism 2222 can both use a second motor linear module or a Y-axis translation drive cylinder. If designed as a second motor linear module, it includes a second motor, a Y-axis lead screw, a second slide, and a Y-axis guide rail. The second motor drives the Y-axis lead screw to rotate, the second slide is adapted to the Y-axis lead screw through an internal threaded hole, and the second slide slides along the Y-axis guide rail.

[0045] The translation seat 1111 is also provided with a wiring seat 12, and the wiring seat 12 is provided with two wiring areas 121 arranged side by side along the X-axis, and the wiring areas 121 each include a first power supply end 52 and a second power supply end 53; the first heating unit 201 is connected to a first power supply end through a first cable, and the second heating unit 202 is connected to a second power supply end through a second cable. The first power supply end and the second power supply end are both referred to as power supply ends 51, and the first power supply end can be selectively electrically connected to the first power supply end 52 or the second power supply end 53 on one wiring area, and the second power supply end can be selectively electrically connected to the first power supply end 52 or the second power supply end 53 on another wiring area. The first power supply end 52 and the second power supply end 53 on the same wiring area 121 are arranged at intervals along the Y-axis. The first power supply end and the second power supply end are both connected to a first cylinder 54, and the first cylinder 54 drives the corresponding first power supply end and the second power supply end to move up and down. The first power supply end and the second power supply end are connected to the corresponding IH induction heating coil. The first power supply end 52 and the second power supply end 53 can provide different alternating currents to the IH induction heating coil, so that it is convenient to select the corresponding power supply end according to the actual heating demand. The first cylinder 54 drives the corresponding first power supply end (or the second power supply end) to descend to form an electrical connection with the corresponding first power supply end 52 (or the second power supply end 53), and the first cylinder 54 drives the corresponding first power supply end (or the second power supply end) to rise to disconnect the electrical connection with the first power supply end 52 (or the second power supply end 53). The first heating unit 201 and the second heating unit 202 can select different power supply ends to achieve power supply switching. For the same heating coil unit, two different heating capacities can be changed. In this way, the first heating unit 201 and the second heating unit 202 can provide at least four different heating capacities. In other embodiments, a third heating coil unit can also be configured. The dual-coil switching heating device described in this article is not limited to a heating device with only two heating coil units, but means that it has at least two heating coil units.

[0046] One of the two stator paint dripping stations 100 is in a heating state, and one of the first heating unit 201 or the second heating unit 202 is selected to heat the stator product of the stator paint dripping station, and the stator product of the other stator paint dripping station is in a non-heating state (for example, loading and unloading or other time periods that do not require heating), so that the stator products of the two stator paint dripping stations are simultaneously in different process stages, and the two stator paint dripping stations are switched to heat; and the first heating unit 201 and the second heating unit 202 can each switch the power supply to change the heating capacity, so that the mobile heating device can provide at least four different heating capacities for any stator paint dripping station to choose. In this way, the switching heating requirements of the two stator paint dripping stations 100 arranged side by side are met, and the two paint dripping stations can switch to a shared heating device. On the premise of meeting the heating requirements, the configuration of the heating device is saved, which is conducive to saving equipment costs, reducing occupied space, and facilitating the optimization of the design layout of functional modules on the equipment.

[0047] In other embodiments, further, the X-axis spacing of the first Y-axis moving mechanism 21 and the second Y-axis moving mechanism 22 on the translation seat 11 is adjustable, and the spacing is adjusted to the X-axis spacing between the two inlets and outlets, so that the first heating unit 201 and the second heating unit 202 can heat the two stator paint dripping stations respectively. The spacing adjustment structure can be an adjustment screw locking position, or an automatic device can be designed to drive the first Y-axis moving mechanism 21 or the second Y-axis moving mechanism 22 to move on the translation seat 11, because the spacing of the first Y-axis moving mechanism 21 and the second Y-axis moving mechanism 22 on the translation seat 11 is usually only two types, namely, the close state and the far state. The close state makes the structure more compact, and the far state is that the spacing is adjusted to the X-axis spacing between the two inlets and outlets, which is convenient for simultaneous heating and is suitable for the situation where the process stages of the two stator paint dripping stations are carried out simultaneously.

[0048] The design focus of the present invention is that it mainly realizes the convenience of heating under the premise of double paint dripping stations, and can select different heating units according to actual heating needs to meet the paint dripping heating requirements of different stator products, which is beneficial to improving the paint dripping quality, and is convenient for weighing and speed measurement.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
