[0040] Reference Figure 1-Figure 7 .

[0041] An intelligent environmentally friendly resistor coating device is used for coating processing of resistors with leads. The present application mainly uses a roller brush coating method to coat magnetic bars with resistors with leads. The device includes:

[0046] The above-mentioned resistor coating equipment is applied to the coating processing of resistors with leads. The present application mainly adopts the roller brush coating method to coat the magnetic rods with resistors with leads. The equipment includes a double-layer workbench 5, and a resistor conveying mechanism that is clockwise or counterclockwise wound on the upper and lower layers of the workbench 5; the resistor conveying mechanism includes a first conveying rail chain 1, a second conveying rail chain 2 connected to the discharge end of the first conveying rail chain 1, and a third conveying rail chain 3 connected to the discharge end of the second conveying rail chain 2; a feeding mechanism 45 and a first quality inspection mechanism are sequentially arranged on the conveying stroke of the first conveying rail chain 1; the front conveying stroke of the second conveying rail chain 2 is arranged on the upper layer of the workbench 5, and a first inspection mechanism and a first baking mechanism are sequentially arranged; the rear conveying stroke of the second conveying rail chain 2 bypasses the end of the workbench 5 downward and is arranged on the lower layer of the workbench 5, and a second baking mechanism is arranged; the front conveying stroke of the third conveying rail chain 3 is arranged on the lower layer of the workbench 5, and a second position inspection mechanism is arranged; the front conveying stroke of the third conveying rail chain 3 The resistor conveying mechanism 45 is formed by the first conveying rail chain 1, the second conveying rail chain 2 and the third conveying rail chain 3, which starts from a part of the upper layer of the work frame 5, detours to the lower layer and then detours to another part of the upper layer. The unloading mechanism 45, the first quality inspection mechanism, the first inspection mechanism, the first baking mechanism, the second baking mechanism, the second position inspection mechanism, the second quality inspection mechanism and the unloading mechanism 45 are sequentially arranged on the conveying track of the resistor conveying mechanism, so that the resistor is coated on the work frame 5 in a cyclic stroke, which saves the space occupied by the equipment while ensuring the coordination of multiple stations; the entire conveying stroke utilizes three conveying rail chains to complete the conveying process of the resistor in the equipment, which is efficient and energy-saving; the equipment sequentially performs quality inspection and position inspection before the resistor is coated, and sequentially performs position inspection and quality inspection during the resistor coating, which improves the yield rate of the finished product after the resistor coating process, and significantly improves the production efficiency of the entire equipment.

[0047] It should be noted that the lead resistor includes a magnetic rod and leads arranged at both ends of the magnetic rod; the resistor is coated, that is, a film is applied on the side of the magnetic rod so that it has a good application effect. The conveyor rail chain in the above embodiment includes two parallel chains, and a lead clamp 4 is provided on the chain plate of each chain. The leads at both ends of the resistor are respectively arranged on the lead clamps 4 of the chains on both sides, and the magnetic rod is suspended between the two chains. It can be understood that both ends of each conveyor rail chain are meshed with a driving gear and a driven gear that drive it to move forward. The resistor moves in the opposite direction following the movement of the conveyor rail chain, and is detected, baked and coated along the way.

[0048] The first conveyor rail chain 1 , the second conveyor rail chain 2 and the third conveyor rail chain 3 can be driven simultaneously by the same drive motor through a transmission device, wherein the second conveyor rail chain 2 moves in the same direction as the first conveyor rail chain 1 , and the third conveyor rail chain 3 moves in the opposite direction to the first conveyor rail chain 1 .

[0049] Next, the above-mentioned intelligent environmentally friendly resistor coating equipment will be further described.

[0050] In one embodiment, the two ends of the first conveyor rail chain 1 are respectively wound around the unloading mechanism 45 and the first quality inspection mechanism, and the conveying stroke of the first conveyor rail chain 1 sequentially receives the discharge end of the unloading mechanism 45 and the feed end of the first quality inspection mechanism; a lead wire flattening device is provided between the unloading mechanism 45 and the first quality inspection mechanism, and the lead wire flattening device includes rolling strips 11 arranged in parallel on both sides of the first conveyor rail chain 1, a roller shaft perpendicular to the conveying stroke of the first conveyor rail chain 1, and rolling rollers 12 arranged at intervals on the roller shaft, and a corresponding roller shaft is provided above the two rolling strips 11, and the roller shaft is connected to the first motor transmission.

[0051] It should be noted that the lead wire rolling device described above can be used to roll the resistor lead wires on the first conveyor rail chain 1. Specifically, the lead wires of some resistors to be processed that are unloaded by the unloading mechanism 45 may be bent and deformed, and need to be rolled to make them straight to avoid affecting the processing operations at the subsequent stations. The roller 12 is driven by the first motor to drive the roller shaft to rotate along the conveying direction of the resistor. The roller 12 and the rolling strip 11 maintain an actual lead wire diameter interval. When the first conveyor rail chain 1 passes by with the resistor to be processed, the roller 12 can roll it flat.

[0052] It should also be noted that the top surface of the rolling strip 11 and the bottom surface of the lead clamping position 4 are kept in the same horizontal direction.

[0053] In one embodiment, the first quality inspection mechanism and the second quality inspection mechanism both include a receiving tray 21, a lead detection device, a grating positioning device and a waste removal device. The lead detection device and the waste removal device are sequentially arranged along the conveying stroke of the receiving tray 21. A transmission gear disc meshing with a conveying rail chain is coaxially arranged on the side of the receiving tray 21, and a plurality of resistance positioning grooves are evenly arranged on the periphery of the receiving tray 21; the grating positioning device includes a first optical fiber sensor 22, and a grating disk 23 coaxially arranged with the receiving tray 21, the grating disk 23 is provided with a grid corresponding to the resistance positioning groove, the sensing end of the first optical fiber sensor 22 is arranged corresponding to the grid, and a controller 24 electrically connected to the waste removal device, the lead detection device and the first optical fiber sensor 22 is provided on the work station frame 5.

[0054] It should be noted that the above-mentioned receiving tray 21 is supported on the conveying stroke of the first conveying rail chain 1. The resistor positioning groove on the receiving tray 21 is provided with a magnetic suction piece, which can absorb the resistor to separate it from the first conveying rail chain 1 and arrange it around the periphery of the receiving tray 21. During the rotation of the receiving tray 21, the resistor is driven to pass through the lead detection device for quality inspection. When the lead detection device detects a resistor with quality problems, a trigger signal is triggered and the grating positioning device performs positioning and recording. According to the positioning record data, the controller 24 internal program calculates the required number of times that the grating disk 23 triggers the first optical fiber sensor 22 when the resistor with quality problems reaches the waste removal device. When the number is reached, the waste removal device is controlled to remove the resistor in place.

[0055] It should be noted that the first optical fiber sensor 22 is a notch-type optical fiber sensor, and its notch corresponds to the grid of the grating disk 23 .

[0056] In this embodiment, the work station frame 5 is provided with a mounting plate 25 on the side of the receiving tray 21, and the lead detection device includes a contact mounting seat 26 provided on the mounting plate 25, and two lead contacts 27 provided on the contact mounting seat 26, and the lead contact 27 is electrically connected to the controller 24, and the two lead contacts 27 are respectively arranged corresponding to the two sides of the resistor positioning groove of the receiving tray 21.

[0057] It should be noted that the two lead contact members 27 are in contact with the leads at both ends of the resistor respectively, and if the resistor is of good quality, a path is formed, otherwise a short circuit is formed. The position of the resistor with quality problems is recorded by the above-mentioned grating positioning device.

[0058] In this embodiment, the waste removal device includes a paddle 28 arranged at the discharge end of the receiving tray 21 and a waste recovery plate 29 arranged below the paddle 28, and a recovery frame is correspondingly provided below the waste recovery plate 29. A second motor connected to the controller 24 is provided on the work station frame 5, and the paddle 28 is connected to the power output end of the second motor.

[0059] It should be noted that when a resistor with quality problems is about to reach the waste rejection device, the second motor drives the paddle 28 to flip under the resistor, and the resistor slides onto the paddle 28. At this time, the second motor reverses and paddles 28, and the resistor falls onto the waste recovery plate 29 and is recovered by the recovery frame.

[0060] The resistor is inspected for quality by the lead inspection device, and the resistor with quality problems is separated from the receiving tray 21 by the waste rejection device to prevent the resistor from entering the next processing station, thereby ensuring the subsequent resistor coating yield.

[0061] In one embodiment, the discharge end of the second quality inspection mechanism corresponds to the upper part of the conveying stroke of the second conveying rail chain 2, and the first position inspection mechanism is provided on the conveying stroke of the second conveying rail chain 2. The second position inspection mechanism and the first position inspection mechanism have the same structure. The first position inspection mechanism includes a misalignment detection component, and the misalignment detection component includes a second optical fiber sensor 31 correspondingly arranged above the second conveying rail chain 2, a top bender 32 correspondingly arranged above the centerline of the second conveying rail chain 2, and a thumbwheel 33 correspondingly arranged below the centerline of the second conveying rail chain 2. The thumbwheel 33 is transmission-connected to the third motor, and the second optical fiber sensor 31, the top bender 32 and the thumbwheel 33 are sequentially arranged along the conveying stroke of the second conveying rail chain 2; the second optical fiber sensor 31 is electrically connected to the top bender 32 and the third motor.

[0062] It can be understood that the second optical fiber sensor 31 is used to detect whether there are leads in the corresponding lead positions 4 on both sides of the second conveying rail chain 2 at the same time. When the second optical fiber sensor 31 only detects that there are leads on only one side of the two corresponding lead positions 4, it means that the resistor is not placed in the corresponding lead position 4, and the resistor is misplaced. At the same time, the top bender 32 is controlled to bend the resistor downward, and the third motor is controlled to drive the dial wheel 33 to rotate to push the bent resistor away from the second conveying rail chain 2.

[0063] In this embodiment, the first position detection mechanism also includes an overlap detection component, which includes a support frame 34 horizontally arranged above the second conveyor rail chain 2, two path detection contact pieces 35 arranged on the support frame 34, and an alarm 36 arranged on the work station frame 5, the front ends of the two path detection contact pieces 35 are spaced apart from the conveying travel surface of the second conveyor rail chain 2 by a lead diameter, and the two path detection contact pieces 35 are electrically connected to the alarm 36.

[0064] It should be noted that when the leads of the two resistors overlap, the lead height in the single lead clamp 4 is higher than the original height, that is, in the conveying stroke of the second conveying track chain 2, the overlapping leads will inevitably contact the two-channel detection contact pieces 35, so that a loop is formed between the two-channel detection contact pieces 35 and the alarm 36, triggering the alarm 36 to alarm.

[0065] More preferably, the alarm 36 is electrically connected to the drive motors driving the first conveyor rail chain 1, the second conveyor rail chain 2 and the third conveyor rail chain 3. When the alarm 36 is triggered, the drive motor is controlled to stop so as to clear the overlapping resistance on the second conveyor rail chain 2 in time.

[0066] In one embodiment, the first baking and coating mechanism and the second baking and coating mechanism both include a roller coating device 41 disposed below the second conveying rail chain 2, a baking device 42 disposed above the second conveying rail chain 2, and an air-drying device 43. The roller coating device 41, the air-drying device 43, and the baking device 42 are arranged in sequence along the conveying stroke of the second conveying rail chain 2. The feeding end of the first baking and coating mechanism is also provided with a baking device 42. The plurality of baking devices 42 are respectively connected to the exhaust gas suction device 44 disposed on the side of the work station frame 5. Activated carbon is provided at the connection point between each baking device 42 and the exhaust gas suction device 44 so as to absorb the exhaust gas in the baking device 42 through the activated carbon.

[0067] It should be noted that the roller coating device 41 applies paint to the surface of the resistor magnetic rod, and a coating roller and a film material are provided under the magnetic rod. The rotation of the coating roller drives the film material to apply paint to the resistor magnetic rod during the movement. The baking device 42 bakes the resistor before and after the coating so that the coating can dry quickly each time. The air drying device 43 accelerates the drying speed, and the exhaust gas generated in the baking device 42 is centrally treated by the exhaust gas suction device 44.

[0068] It is understandable that the upper and lower layers of the same section of the work station 5 are both provided with a baking coating mechanism, so that the resistor can be coated with film material at least twice. It is foreseeable that according to the actual needs of the actual number of coating layers, the work station 5 of each section can be gradually increased to achieve twice the result with half the effort, while also saving a lot of occupied space.

[0069] In one embodiment, an “L”-shaped side stopper 51 is provided at one end of the work station 5 close to the second conveying rail chain 2 , and the side stopper 51 is attached to the rear conveying stroke of the second conveying rail chain 2 .

[0070] It should be noted that the rear section of the conveying stroke of the second conveyor rail chain 2 starts at the turning point from the upper layer to the lower layer of the work station frame 5. In particular, the second conveyor rail chain 2 is in an inverted state when it is in the lower layer. The "L"-shaped side stop 51 is used to prevent the resistor from falling during the rear section of the conveying stroke of the second conveyor rail chain 2, thereby allowing the resistor to be smoothly transferred from the inverted state of the second conveyor rail chain 2 to the upright state of the third conveyor rail chain 3.

[0072] S1, transporting the resistor to be processed from the unloading mechanism 45 to the first quality inspection mechanism through the first conveyor rail chain 1, the first quality inspection mechanism performs quality inspection on the resistor to be processed, and transfers the resistor to be processed with qualified quality to the next process;

[0074] S3, coating the resistor to be processed transported by the second conveyor rail chain 2 in turn by means of the first baking coating mechanism and the second baking coating mechanism, obtaining a finished resistor and transferring it to the next process;

[0075] S4, the finished resistor is transferred through the third conveying rail chain 3 and the finished resistor is successively passed through the second position detection mechanism for position detection and the second quality inspection mechanism for quality detection, and the finished resistor that passes the detection is conveyed to the discharging mechanism 46 through the third conveying track.

[0076] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
