DETAILED DESCRIPTION

[0058] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0059] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0060] The present invention provides a resistance detection and insulating paint coating device 100, which is used to implement resistance detection and insulating paint coating operations on a workpiece 200. The workpiece 200 targeted by the resistance detection and insulating paint coating device 100 is generally an alloy resistor product, and its structure can be seen in Fig.14 and Fig.15 The workpiece 200 includes a resistor body 201 and pins 202 disposed on both sides of the resistor body 201 in the horizontal direction. The resistor body 201 is usually made of alloy resistor material, and the pins 202 are usually made of conductive materials such as brass or copper. In some scenarios, the resistor body 201 needs to be insulated, so it needs to be coated with insulating paint. It should be noted that the structure of the workpiece 200 shown in the figure is only for reference, and the specific shape, size and structure of the workpiece 200 are not limited.

[0061] For further information, see Figures 1 to 13 The resistance detection and insulating paint coating device 100 includes a base 10, a supporting mechanism 20, a detection mechanism 30 and a pressing mechanism 40.

[0062] The supporting mechanism 20 is used to support the workpiece 200 and is disposed on the base 10. For details, please refer to Figure 1 and Figure 5 The bearing mechanism 20 includes a body 21 and a first elastic member 22. The first elastic member 22 is elastically and retractably arranged in the up-down direction, and can generally be arranged as a compression spring. The lower end of the first elastic member 22 is connected to the base 10, and the upper end of the first elastic member 22 supports the body 21, so that the body 21 is elastically supported on the base 10. Please continue to refer to Figures 6 to 13 A bearing groove 210 for bearing the workpiece 200 is provided on the upper side of the main body 21. The shape and size of the bearing groove 210 can be set to be adapted to the workpiece 200. A plurality of second channels 214 extending in the up-down direction are provided at the bottom of the bearing groove 210. The second channels 214 are set through the main body 21 for the detection probe 31 in the detection mechanism 30 to pass through, thereby contacting the product.

[0063] Please continue reading Figure 5 , the detection mechanism 30 is arranged on the base 10 and is arranged below the bearing slot 210. Specifically, a mounting slot is recessed on the base 10, and the detection mechanism 30 is arranged in the mounting slot. The body 21 is slidably installed in the mounting slot along the up and down directions, and is elastically supported by the first elastic member 22 arranged in the mounting slot. The detection mechanism 30 includes a plurality of detection probes 31 installed on the base 10, and the plurality of detection probes 31 are inserted into each of the second channels 214 in a one-to-one and relatively movable manner. Four detection probes 31 are usually provided, of which two detection probes 31 are used for supplying current and the other two detection probes 31 are used for taking voltage, so that the resistance value detection of the workpiece 200 can be realized by the four-wire method. It should be noted that a circuit switch for controlling the current supply and sampling of the detection probes 31 should also be provided on the base 10, so that the control of the resistance value detection timing can be realized by the switch.

[0064] The pressing mechanism 40 is disposed on the base 10, and includes a driving member 41 and a pressing block 42 disposed above the body 21. A cavity 420 is formed in the pressing block 42, and the cavity 420 is used to store insulating paint. Figures 17 to 26 The pressing block 42 is movably mounted on the base 10 in the up-down direction, and the driving member 41 is drivingly connected to the pressing block 42 so that the pressing block 42 has a first position (eg, Figure 1 , Figure 2 and Figure 5 As shown in FIG. 1 , at this time, the resistance detection and insulating paint coating device 100 is in the first working state. When the pressing block 42 is driven downward to press against the bearing mechanism 20, it is in the second position (as shown in FIG. Figures 17 to 26 As shown), at this time, the resistance detection and insulating paint coating device 100 switches to the second working state. When the pressing block 42 is in the second position, the first elastic member 22 is compressed so that the body 21 is pressed down until the plurality of detection probes 31 extend upward into the bearing groove 210, thereby enabling the resistance detection operation of the workpiece 200 to be realized. And when the pressing block 42 is in the second position, the cavity 420 can be opened. After the cavity 420 is opened, the resistance detection and insulating paint coating device 100 switches to the third state, at which time the insulating paint in the cavity 420 flows into the bearing groove 210 to achieve insulating paint coating on the workpiece 200. It should be noted that there can be multiple ways to open the cavity 420, and the timing of opening should be controllable, such as manually operating an opening and closing valve. In this way, the workpiece 200 can be detected before and after the insulating paint is applied.

[0065] In this embodiment, the resistance detection and insulating paint coating device 100 can be used to complete the insulating paint coating operation and the resistance detection operation of the workpiece 200 in the same process. Specifically, after the workpiece 200 is fixed by the support mechanism 20, the driving member 41 can be operated to press the pressing block 42, and the resistance detection operation is performed on the workpiece 200, and then the cavity 420 is opened to perform the insulating paint coating operation. After the insulating paint is dried and formed, the detection mechanism 30 is controlled to perform the resistance detection operation on the workpiece 200, and then the two resistance detection results can be compared to verify whether the insulating paint coating process is qualified. In this way, on the one hand, only a single pick-up and placement fixing operation is required for the workpiece 200 to complete the two processes, thereby improving the production efficiency. On the other hand, two resistance detections of the workpiece 200 are achieved under substantially the same conditions, and the detection results are highly reliable. In addition, only a single set of equipment is required, thereby reducing the production cost.

[0066] On the basis of the previous implementation, further, the pressing block 42 includes an upper wall 421 and a lower wall 422, the cavity 420 is arranged between the upper wall 421 and the lower wall 422, and the upper wall 421 is provided with a feed port 423 connected to the cavity 420, so that the insulating paint coating can be poured into the cavity 420 from the feed port 423. It should be noted that the feed port 423 should be set to judge whether the insulating paint coating is sufficiently poured into the cavity 420 by observing the feed port 423, and the size of the cavity 420 is set to be just enough to accommodate the size of the insulating paint coating coating suitable for the primary workpiece 200.

[0067] In order to realize the opening operation of the cavity 420. Optionally, the pressing mechanism 40 further includes a sleeve 43 and an insert block 44, wherein the sleeve 43 extends downward from the upper wall 421, and a guide channel extending from top to bottom and open at the lower end is formed in the sleeve 43, the cavity 420 is arranged around the outer periphery of the guide channel, a gap is formed between the lower end of the sleeve 43 and the lower wall 422, and the lower wall 422 is provided with a socket 424 located below the guide channel. The upper end of the plug block 44 is inserted into the guide channel, and the lower end of the plug block 44 is inserted into the socket 424. A cavity 440 is formed in the plug block 44. A first opening 441 connected to the cavity 440 is opened on the circumferential side of the plug block 44. A second opening 442 connected to the cavity 440 is opened on the lower side of the plug block 44. The second opening 442 is located correspondingly above the bearing groove 210. The plug block 44 is movably arranged in the up and down directions to have a closed position upward relative to the sleeve 43, and an open position downward relative to the sleeve 43.

[0068] When the plug block 44 is located at the closed position, the first opening 441 is covered by the sleeve 43, so that the cavity 420 is separated from the receiving cavity 440, thereby closing the cavity 420. When the plug block 44 is located at the open position, the first opening 441 is located within the height range of the gap, so that the cavity 420 is connected to the receiving cavity 440 through the first opening 441, thereby opening the cavity 420. In this way, the opening and closing of the cavity 420 can be controlled by operating the up and down movement position of the plug block 44. In this embodiment, when it is necessary to open the cavity 420, the plug block 44 can be controlled to move downward, and then the first opening 441 is lowered to the gap position, so that the insulating paint in the cavity 420 flows into the receiving cavity 440 through the first opening 441, and then flows from the second opening 442 to the bearing groove 210, so as to realize the immersion coating operation of the resistance body part 201 in the workpiece 200. In this embodiment, after the insert block 44 moves downward, the second opening 442 , ie, the outflow position of the insulating paint, is lower and closer to the upper surface of the resistor 201 , which can effectively reduce the splashing of the insulating paint.

[0069] In order to realize the downward movement of the plug block 44, the resistance detection and insulating paint coating device 100 is switched from the second working state to the third working state. In one embodiment, the driving member 41 includes a mounting block 411 fixedly connected to the upper end of the pressing block 42, and the upper end of the guide channel passes through the upper wall 421. The pressing mechanism 40 also includes a third elastic member 45 connected between the mounting block 411 and the plug block 44, and a locking structure 46 arranged between the plug block 44 and the pressing block 42. The third elastic member 45 is elastically and telescopically arranged in the up and down directions and inserted into the guide channel. When the locking structure 46 is in the locked state, the plug block 44 is limited in the closed position, and the third elastic member 45 is compressed to store energy. When the locking structure 46 is switched to the unlocked state, the plug block 44 can move relative to the sleeve 43, so that it can quickly move from the closed position to the open position under the drive of the third elastic member 45.

[0070] And, if Fig.23 and 26 As shown, when the plug block 44 moves to the open position, its lower end abuts against the upper end of the carrying mechanism 20, specifically abuts between the two fixed blocks 23 of the carrying mechanism 20, and maintains a certain distance from the workpiece 200, so that its open position is reliably limited, so that the first opening 441 and the top surface of the lower wall 422 are just aligned, and the insulating paint in the cavity 420 can basically flow out without any residue. And the distance between the second opening 442 and the workpiece 200 is maintained within a reasonable range, which will neither affect the outflow of the insulating paint nor cause the insulating paint to splash.

[0071] For further information, please refer to Figure 3 , Figure 4 , Fig.19 and Fig.23 The locking structure 46 includes a locking hole 461 provided in the insert block 44, and a locking pin 462 sequentially provided in the pressing block 42 and the sleeve 43. When the locking structure 46 is in a locked state, the locking pin 462 is inserted into the locking hole 461. When the locking structure 46 is in an unlocked state, the locking pin 462 is away from the locking hole 461. In this way, the locking structure 46, which cooperates with the locking hole 461 and the locking pin 462, can limit the insert block 44 in the closed position, and the structure is simple and reliable.

[0072] Furthermore, if Figure 4 As shown, the pressing block 42 is detachably connected to the mounting block 411 via a mounting pin 47. In this way, the pressing block 42 can be disassembled and pulled down for cleaning.

[0073] In order to realize the up and down movement of the pressing block 42, optionally, refer to Figure 2The driving member 41 further comprises a handle 412 and a connecting rod mechanism 413, wherein the connecting rod mechanism 413 is movably mounted on the machine base 10, the handle 412 is rotatably connected to the driving end of the connecting rod mechanism 413, and the mounting block 411 is connected to the actuating end of the connecting rod mechanism 413. In this way, the rotation of the handle 412 is converted into the up and down movement of the pressing block 42 in a stable and reliable manner, which is convenient for operation.

[0074] Based on the above embodiment, optionally, please continue to refer to Figures 6 to 13 ,and Fig.16 The bottom surface of the bearing groove 210 includes a first area 211 and second areas 212 arranged on both sides of the first area 211 in the horizontal direction. The first area 211 is located below the second opening 442, and the second area 212 is higher than the first area 211. Both ends of the first area 211 in the front-back direction protrude from the second areas 212. In this embodiment, the first area 211 is arranged corresponding to the barrier portion 201, and its range should be appropriately larger than the barrier portion 201, so that after the insulating varnish flows into the bearing groove 210, it is confined within the range of the first area 211, and the barrier portion 201 is fully immersed. The second area 212 is arranged corresponding to the pin portion 202 to achieve accurate positioning of the workpiece 200. The arrangement of the first area 211 slightly lower than the second area 212 enables a space for the insulating coating varnish to flow through the barrier portion 201 when the workpiece 200 is placed in the bearing groove 210.

[0075] Please continue reading Figures 6 to 13 The bearing mechanism 20 also includes two fixed blocks 23 corresponding to the two second areas 212. Each of the fixed blocks 23 is slidably installed on the body 21 in the transverse direction, so as to have a locking position located above the corresponding second area 212 and an unlocking position laterally away from the bearing groove 210. Two sealing strips are arranged at intervals in the front-to-back direction on the lower side of each of the fixed blocks 23. Preferably, the fixed blocks 23 are integrally formed and made of rubber material, so that the sealing strip has good sealing performance. Guide grooves 215 are respectively arranged on both sides of each of the second areas 212 in the front-to-back direction. The bottom of each of the guide grooves 215 is not lower than the first area 211 and not higher than the second area 212. Each of the sealing strips is correspondingly slidably inserted in each of the guide grooves 215. In this way, when the two fixing blocks 23 are in the locking position, on the one hand, they can effectively fix the workpiece 200, and on the other hand, together with the first area 211, they can form a space that can accommodate insulating paint. The barrier body 201 can be effectively immersed in the insulating paint in the space and fully coated with insulating paint.

[0076] like Fig.16As shown, preferably, the resistance detection and insulating paint coating device 100 in this embodiment can also detect the insulating performance of the insulating paint after the insulating paint is dried and formed. Specifically, the first area 211 is provided with a first channel 213 extending downward, and a plurality of the second channels 214 are correspondingly provided in each of the second areas 212, and a waste discharge channel 216 is also provided in the body 21, and the waste discharge channel 216 is used to discharge excess insulating paint waste liquid. The waste discharge channel 216 communicates with the outside of the bearing groove 210 and the body 21, and the waste discharge channel 216 is connected to the upper end of the first channel 213. In a preferred embodiment, the waste discharge channel 216 is configured to be openable or blockable, so that it is opened after the resistance body 201 is immersed for a sufficient time to discharge excess insulating paint coating to avoid insufficient coating. The detection mechanism 30 further includes a loading probe 32 correspondingly disposed below the first area 211. The loading probe 32 can be relatively movably inserted into the first channel 213. The loading probe 32 is used to contact the workpiece 200 in the loading slot 210 after the workpiece 200 is coated with insulating paint. Figure 20 to Figure 26 After the insulating paint coating operation is completed, the loading probe 32 can be operated to touch the bottom of the resistor body 201. At this time, the resistance detection and insulating paint coating device 100 is switched from the third working state to the fourth working state. When the loading probe 32 supplies pressure, it can be verified whether the insulating paint is coated in place and dried and formed.

[0077] Preferably, the lower ends of the loading probes 32 and the detection probes 31 are respectively mounted on the base 10 through second elastic members 33, and the second elastic members 33 are elastically retractable in the up-down direction. Preferably, the second elastic members 33 are compression springs, so that, on the one hand, each probe can fully contact with the workpiece 200 to ensure detection reliability, and on the other hand, it can prevent the rigidity of each probe from being too large to cause damage to the workpiece 200.

[0078] Further, please continue to refer to Fig.16 , Fig.23 and Fig.26The bearing mechanism 20 further includes a baffle 24. The body 21 is provided with a slot 217 extending in the transverse direction. The slot 217 is connected to the first channel 213. The baffle 24 is movably inserted into the slot 217, so as to have an insertion position for inserting and blocking the first channel 213, and a withdrawal position away from the first channel 213. When the baffle 24 is located at the insertion position, the lower side of the baffle 24 presses against the upper end of the loading probe 32. This prevents the loading probe 32 from contacting the workpiece 200 before the insulating paint is applied, which affects the insulating paint coating effect and the resistance value detection accuracy. At this time, the second elastic member 33 at the lower end of the loading probe 32 is compressed to store energy. When the baffle 24 moves to the withdrawal position, the upper end of the loading probe 32 moves upward under the drive of the corresponding second elastic member 33 to pass through the first channel 213, and is inserted into the supporting groove 210, and contacts the resistor body 201 in the supporting groove 210 that has been coated with insulating paint. When the loading probe 32 and the detection probe 31 work at the same time, it can be determined whether the insulating performance of the insulating paint meets the corresponding design requirements by obtaining the change in the resistance value of the detected workpiece 200.

[0079] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the present invention.
