[0025] The side edge clamp 4 is arranged on the opposite side of the switch 2 of the electric control box 1, and in the embodiment, the side edge clamp 4 comprises a fixed base 41, connecting rods 42, elastic elements 43, a clamping opening 44 and a handle 45. The connecting rods 42 are arranged at four corners of the fixed base 41 in a symmetrical and vertical manner, and the connecting rods 42 are telescopic rods in a rotary locking mode. The elastic elements 43 are arranged at the other ends of the connecting rods 42. The clamping opening 44 is connected with the handle 45 and the elastic elements 43 in a linkage mode. The handle 45 is pressed to drive the clamping opening 44 to move in the opposite direction of the pressing direction, so that the clamping opening 44 is opened or closed, and the electric control box 1 is fixed on the bearing device A.
[0026] Specifically, as shown in Figure 3 the contact is good, the relay is turned on, the normally open switch is closed, and the green light is on; the normally closed switch is open, and the red light is off. When the contact is not good or is disconnected, the relay is turned off, the normally open switch is open, the green light is off, the normally closed switch is closed, and the red light is on. According to the above principle, the red light indicates that the contact is not good or there is no contact; the green light indicates that the contact is good. The device detects whether the bearing device and the workpiece carrier conductive bowl are in good contact through an electrical circuit, and feeds back to the red and green lights visible to the naked eye. If the contact is poor, the buzzer will prompt. The copper head can be detected whether it maintains good contact with the bowl during the operation of the bearing device.
[0027] Specifically, the test preparation is as follows:
[0028] 1. Electrical part: The internal 24VDC lithium battery of the device needs to be charged before testing (a rechargeable battery);
[0029] 2. Mechanical part: A standard sample skid and a standard bearing device are used as the measurement reference. Before testing, the bowl part needs to be added with an insulating pad and replaced with an insulating bolt;
[0030] 3. The flatness error of the four conductive bowls of the workpiece carrier is detected, and a horizontal elevation is marked to ensure that the flatness error of the top surface of the four conductive bowls is extremely small;
[0031] 4. The levelness of the bearing device 1 to the front and rear bearing device copper heads is detected, and the height error of the top surface of the copper heads at the bottom of the front and rear bearing devices is strictly controlled.
[0032] Test process:
[0033] Hang the electrophoresis pry on the electrophoresis bearing device
[0034] Fix the test device on the rear bearing device, connect the second lead of the detector to the workpiece carrier, and connect the first lead to the bearing device. The lead end is provided with a connecting clamp to clamp the workpiece carrier and the bearing device, and the lead and the workpiece carrier and the bearing device are connected.
[0035] Turn on the test device knob switch, at this time the device green light, according to the process speed running bearing device and tracking. Bearing device with workpiece carrier and detector through electrophoresis tank; if the bearing device and workpiece carrier contact well, detection circuit is on, detector green light, red light is bad; if the contact is poor, the detection circuit is not on, green light off red light, the buzzer sounds.
[0036] Bearing device out of the tank stage, the left red light,
[0037] Stop the bearing device running, record the bearing device position.
[0038] Through the test, it is found that the bearing device guide rail installation problem; after measurement, it is found that the left side of the bearing device track and the right side deviation 9mm, after adjustment through the test, the error is within the acceptable range; now the project electrophoresis is generally charged out of the tank, that is, the out of the tank stage, the rectifier power supply is normally pressurized, if the copper head and the pry bowl contact is poor at this time, there will be overheating or even fire phenomenon, after a long time accumulation, it may affect the normal contact and electrophoresis of the horizontal section; the conductive detector can be used to analyze and judge whether the "fire" problem of the current project is caused by poor contact. Install the detector on the top of the bearing device, two leads are connected to the bearing device and the workpiece carrier respectively, and then the bearing device runs through the electric tank, according to the position of the red light, the position of the poor contact can be judged. Adjust the height of the corresponding position track, eliminate the poor contact of the bottom nozzle direction, solve the fire problem; the principle of the conductive detector is simple and reliable, and the manufacturing cost is low, which can also be used for new projects. Through the conductive detection, the position of the poor contact of the new project is judged in advance, and measures are taken early (such as adjusting the track height, the direction of the tank bottom nozzle) to avoid the "fire" caused by poor contact, and the "fire" is eliminated in the bud.
[0039] Finally, it should be pointed out that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
