Description

Technical Field

[0001] The present invention relates to the technical field of electronic manufacturing technology, and in particular to a fully automatic tin-immersion machine for automatic tin-immersion. Background Art

[0002] The fully automatic tinning machine is a device used for tinning the pins of resistors and capacitors. It can automatically complete the tinning operation of the pins of resistors and capacitors. The fully automatic tinning machine is equipped with a control system and sensors, which can control the transmission movement of the pins of resistors and capacitors during the tinning process. By controlling the position of the pins of resistors and capacitors and the depth of the pins inserted into the tin tank, the stability and consistency of the tinning process are ensured. The tinning results are monitored by sensors, and the vibration and swing mechanism of the pins of resistors and capacitors during the tinning process is designed to ensure the uniformity and consistency of the tinning. This is a technical revelation for the fully automatic tinning machine.

[0003] The research on the fully automatic tinning machine found the following problems:

[0004] The fully automatic tinning machine needs to tin the pins of resistors and capacitors. Since one end of the resistor and capacitor pins needs to be tinned first, a special conversion robot needs to be designed to clamp the other end after tinning. The conversion process must keep the ends of all resistor and capacitor pins in the same horizontal plane to avoid different re-tinning lengths, resulting in inconsistent tinning effects.

[0005] At present, CN201811147322.3 in the prior art discloses an automatic tinning machine, which includes a feeding device; a turntable device, which is provided with a feeding station, a fluxing station, a tinning station, a cooling station, a defective product removal station and a feeding station; a feeding module, which is arranged at the feeding station; a fluxing module, which is arranged at the fluxing station; a tinning module, which is arranged at the tinning station; a cooling module, which is arranged at the cooling station; a defective product removal module , which is arranged at the defective product removal station; the unloading module, which is at the receiving unloading station; the control device is electrically connected to the loading device, the turntable device, the loading module, the flux loading module, the tinning module, the cooling module, the defective product removal module and the unloading module, with high production efficiency, stable operation, high production quality, low defective rate, and the ability to automatically detect defective products, separate good products from defective products, and have the advantages of fast automatic loading speed, automatic tinning, reduced production costs, and reduced labor;

[0006] The present invention can mainly solve the problem that a full-automatic tinning machine cannot evenly distribute and discharge materials for resistor and capacitor pins. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a fully automatic tin dipping machine for automatic tin dipping to solve the problems described in the above background technology.

[0008] The purpose and effect of the fully automatic tin dipping machine for automatic tin dipping of the present invention are achieved by the following specific technical means: a fully automatic tin dipping machine for automatic tin dipping, comprising a workbench, a feed conveyor belt is arranged at the upper end of the workbench, a unloading mechanism is arranged on the side of the workbench close to the feed conveyor belt, a soldering mechanism is provided at the discharge end of the workbench close to the feed conveyor belt, a discharge conveyor belt is provided at one end of the workbench close to the soldering mechanism, and a movable vibration plate is provided on the side of the unloading mechanism away from the feed conveyor belt.

[0009] Furthermore, a controller is provided on one side of the workbench, and the controller is connected to the soldering mechanism, the unloading mechanism, the feeding conveyor belt and the discharging conveyor belt loop through electric wires.

[0010] Furthermore, the feed conveyor belt is arranged horizontally at the upper end of the workbench, and there are 5 unloading mechanisms arranged, and the lower end of the unloading mechanism corresponds to the feed conveyor belt in a vertical direction;

[0011] Furthermore, the soldering mechanism includes a robotic arm.

[0012] Furthermore, a discharging rack is provided on one side of the workbench close to the discharging conveyor belt, and the discharging rack is in a mouth shape.

[0013] Furthermore, a rotary bearing is rotatably penetrated inside the discharging rack, a material guide rack is surrounded on the outside of the rotary bearing, and a partition is provided on the inside of the material guide rack.

[0014] Furthermore, the material guide frame is in a semicircular arc shape, the material guide frame on the side of the rotating bearing is vertically corresponding to the discharge end of the discharge conveyor belt, and the material guide frame rotates 360° on the outside of the rotating bearing.

[0015] Furthermore, grooves are provided on both sides of the partition plate close to one end of the rotary bearing, and each two grooves form a group, and multiple groups of grooves are provided.

[0016] Furthermore, one end of the guide frame away from the partition is rotatably connected to a rotating shaft, one side of the rotating shaft is swingably connected to a lining plate, one end of the lining plate close to the partition is sequentially arranged with a curved rod and a sliding block, and one end inside the partition groove is slidably connected to a telescopic rod.

[0017] Furthermore, the rotating shaft and the lining plate are matched with each other, the rotating shafts are arranged in multiple groups, the lining plates are tilted and swung through the rotating shafts, and the rotating shafts are connected in series.

[0018] Furthermore, the lining plate is centered on the rotating shaft, the lining plate is separated from the inner side of the material guide frame, the lining plate is arranged horizontally inside the material guide frame, there are multiple lining plates arranged, and the lining plates are connected to the partition plate through a curved rod and a slider.

[0019] Furthermore, the telescopic rod is arranged in two sections, the fixed end of the telescopic rod is installed on the inner wall of the groove of the partition, and the sliding end of the telescopic rod is close to one end of the slider.

[0020] Furthermore, one end of the slider is connected to the sliding end of the telescopic rod, and the curved rod is arranged in an arc shape. When the lining plate does not swing, the slider is located inside the partition groove close to one end of the telescopic rod.

[0021] Beneficial effects:

[0022] 1. The guide rack on the side of the rotating bearing is vertically corresponding to the discharge end of the discharge conveyor belt, so the resistor and capacitor pins fall into the inside of the guide rack after being tinned. Since the guide rack is evenly arranged on the outside of the rotating bearing, the guide rack at the end where the resistor and capacitor pins fall rotates downward through the rotating bearing. Repeating the above steps, the resistor and capacitor of the discharge conveyor belt can fall downward, so that the guide racks on both sides of the rotating bearing have a weight difference, thereby assisting the guide rack to rotate 360° through the rotating bearing;

[0023] 2. Since solder is formed at one end of the resistor and capacitor pins, the weights of the two ends of the resistor and capacitor pins are different. After multiple resistor and capacitor pins fall into the guide rack through the discharge conveyor belt, the lining plate swings in different directions according to the resistor and capacitor. The lining plate inside the guide rack swings in different directions through the rotating shaft. When the lining plate swings, the curved rod slides in the groove of the partition through the slider. At this time, the curved rod slides toward the end away from the lining plate through the slider. Since the inside of the guide rack is divided into two inner cavities on both sides by the partition, the resistor and capacitor can enter the inside of the guide rack. Through the above steps, the resistor and capacitor can be separated and discharged according to the direction of the resistor and capacitor pins, avoiding the situation where the two ends of the resistor and capacitor pins are in different directions when the resistor and capacitor are discharged, resulting in the need for manual sorting later;

[0024] 3. As the rotary bearing rotates, when the internal resistor and capacitor of the guide frame impact one end of the liner, the liner is limited and fixed by the bent rod and the slider. At this time, the liner cannot swing through the rotating shaft, which can limit the swing angle of the liner. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] As attached Figure 1 To Attachment Figure 8 As shown:

[0038] Embodiment 1: A fully automatic tin dipping machine for automatic tin dipping comprises a workbench 1, a feeding conveyor belt 102 is arranged at the upper end of the workbench 1, a feeding mechanism 101 is arranged on the side of the workbench 1 close to the feeding conveyor belt 102, a soldering mechanism 103 is arranged at the discharging end of the workbench 1 close to the feeding conveyor belt 102, a discharging conveyor belt 104 is arranged at one end of the workbench 1 close to the soldering mechanism 103, and a movable vibration plate 105 is arranged on the side of the discharging mechanism 101 away from the feeding conveyor belt 102;

[0039] Wherein: a workbench 1, a controller is provided on one side of the workbench 1, and the controller is connected to the soldering mechanism 103, the unloading mechanism 101, the feeding conveyor belt 102 and the discharging conveyor belt 104 through wires;

[0040] A feeding conveyor belt 102 is arranged horizontally at the upper end of the workbench 1, and five unloading mechanisms 101 are arranged, and the lower end of the unloading mechanism 101 corresponds to the feeding conveyor belt 102 in a vertical direction;

[0041] The tin immersion mechanism 103 includes a mechanical arm;

[0042] The resistor and capacitor pins are transported to one end of the soldering mechanism 103 through the feeding conveyor belt 102, and the soldering clamp of the robot arm clamps the resistor and capacitor pins at the end B to the end A and immerses them in flux and tin. After the tinning is completed, the resistor and capacitor pins are handed over to the upper end of the discharging conveyor belt 104;

[0043] A discharging conveyor belt 104, a discharging rack 2 is provided on one side of the workbench 1 close to the discharging conveyor belt 104, and the discharging rack 2 is in a mouth shape;

[0044] Wherein: the moving vibration plate 105 transfers the resistor and capacitor pins to the upper end of the unloading mechanism 101 in batches, the unloading mechanism assists the resistor and capacitor pins to be evenly arranged on the upper end of the feeding conveyor belt 102, the resistor and capacitor pins are transported to one end of the soldering mechanism 103 through the feeding conveyor belt 102, the soldering clamp of the robot arm clamps the resistor and capacitor pin end B to soak the end A in flux and tin, after the soldering is completed, the resistor and capacitor pins are handed over to the upper end of the discharging conveyor belt 104, and the resistor and capacitor pins are transported to the inside of the discharging rack 2 through the discharging conveyor belt 104;

[0045] Example 2: Refer to the attached manual Figure 1-5 It can be seen that the difference between Example 2 and Example 1 is that a rotary bearing 201 is rotatably penetrated inside the discharge rack 2, a guide rack 202 is surrounded on the outside of the rotary bearing 201, and a partition 4 is provided on the inner side of the guide rack 202;

[0046] Wherein: the guide frame 202 is semicircular, the guide frame 202 on the side of the rotating bearing 201 is vertically corresponding to the discharge end of the discharge conveyor belt 104, and the guide frame 202 is 360° rotatable and movable on the outside of the rotating bearing 201;

[0047] The guide frame 202 on the side of the rotating bearing 201 is vertically corresponding to the discharge end of the discharge conveyor belt 104, so the resistor and capacitor pins fall into the inside of the guide frame 202 after being tinned. Figure 3 As shown;

[0048] The partition plate 4 has grooves on both sides of one end of the partition plate 4 close to the rotary bearing 201, and the grooves are grouped in pairs, and there are multiple groups of grooves;

[0049] The partition 4 divides the interior of the material guide frame 202 into two cavities on both sides;

[0050] Wherein: the guide frame 202 on the side of the rotating bearing 201 is vertically corresponding to the discharge end of the discharge conveyor belt 104, so the resistor and capacitor pins fall into the inside of the guide frame 202 after being dipped in tin. Since the guide frame 202 is evenly arranged on the outside of the rotating bearing 201, the guide frame 202 at the end where the resistor and capacitor pins fall is rotated downward through the rotating bearing 201. Repeating the above steps can make the resistor and capacitor of the discharge conveyor belt 104 fall downward, so that the guide frames 202 on both sides of the rotating bearing 201 have a quantity difference, thereby assisting the guide frame 202 to rotate 360 ​​degrees through the rotating bearing 201;

[0051] Example 3: Refer to the attached manual Figure 5-8 It can be seen that the difference between Example 3 and Examples 1 and 2 is that the end of the guide frame 202 away from the partition 4 is rotatably connected to the rotating shaft 3, one side of the rotating shaft 3 is swingably connected to the lining plate 301, the end of the lining plate 301 close to the partition 4 is sequentially arranged with a curved rod 302 and a slider 303, and one end of the groove of the partition 4 is slidably connected to the telescopic rod 401;

[0052] Wherein: the rotating shaft 3, the rotating shaft 3 and the lining plate 301 are matched, the rotating shaft 3 is arranged in multiple groups, the lining plates 301 are all tilted and swung through the rotating shaft 3, and the rotating shafts 3 are connected in series;

[0053] The lining plate 301 is centered on the rotating shaft 3. The lining plate 301 is separated from the inner side of the material guide frame 202. The lining plate 301 is arranged in a transverse manner inside the material guide frame 202. There are multiple lining plates 301 arranged. The lining plate 301 is connected to the partition plate 4 through a curved rod 302 and a slider 303.

[0054] The lining plate 301 is connected to the partition plate 4 through a curved rod 302 and a slider 303. Figure 6 As shown;

[0055] The telescopic rod 401 is provided in two sections, the fixed end of the telescopic rod 401 is installed on the inner wall of the groove of the partition 4, and the sliding end of the telescopic rod 401 is close to one end of the slider 303;

[0056] A curved rod 302 and a slider 303, one end of the slider 303 is connected to the sliding end of the telescopic rod 401, the curved rod 302 is arranged in an arc shape, and when the lining plate 301 does not swing, the slider 303 is located inside the groove of the partition plate 4 near one end of the telescopic rod 401;

[0057] When the lining plate 301 is not swinging, the slider 303 is in the groove of the partition plate 4 near one end of the telescopic rod 401. As the rotating bearing 201 rotates, the resistor and capacitor pins inside the guide frame 202 impact one end of the lining plate 301. The lining plate 301 is fixed by the curved rod 302 and the slider 303. At this time, the lining plate 301 cannot swing through the rotating shaft 3. Please refer to the attached manual for details. Figure 6 As shown;

[0058] Since a groove is provided on one side of the partition plate 4, the slider 303 slides inside the groove of the partition plate 4, and the sliding distance of the slider 303 is limited, and the swing angle of the lining plate 301 can be limited by the slider 303 and the curved rod 302;

[0059] Among them: since one end of the resistor and capacitor pins is tinned, after a plurality of resistor and capacitor pins fall into the guide rack 202 through the discharge conveyor belt 104, the two ends of the resistor and capacitor pins are replaced and alternately tinned. In addition, the vibration and swing of the resistor and capacitor pins in the tin bath are increased to ensure sufficient tinning. The lining plate 301 inside the guide rack 202 swings in different directions through the rotating shaft 3. When the lining plate 301 swings, the curved rod 302 slides in the groove of the partition plate 4 through the slider 303. At this time, the curved rod 302 slides toward the end away from the lining plate 301 through the slider 303. Since the interior of the guide rack 202 is divided into two side cavities by the partition plate 4, the resistor and capacitor can enter the interior of the guide rack 202. Through the above steps, the resistor and capacitor can be separated and discharged according to the direction of the resistor and capacitor pins, avoiding the situation where the two ends of the resistor and capacitor are in different directions when the resistor and capacitor are discharged, resulting in the need for manual sorting later;

[0060] As the rotating bearing 201 rotates, when the internal resistor and capacitor of the guide frame 202 impact one end of the lining plate 301, the lining plate 301 is limited and fixed by the curved rod 302 and the slider 303. At this time, the lining plate 301 cannot swing through the rotating shaft 3, which can limit the swing angle of the lining plate 301.
