Description

Technical Field

[0001] The utility model relates to the technical field of electroplating processing, in particular to an electroplating processing suspension structure. Background Art

[0002] The hanging technology in the electroplating process is a key step. It involves fixing the workpiece to a special hanging device or hook and transporting it through a conveyor rack to ensure that it is evenly placed in the electrolyte for electroplating. This hanging method must take into account the size, shape and weight distribution of the workpiece so that the current passes evenly, which helps to obtain a coating with uniform thickness and good adhesion. The hanging process must also ensure that the distance between the workpieces or between the workpieces and the tank wall is appropriate to prevent mutual interference and plating defects. In order to improve production efficiency and ensure the quality of the coating, the hanging system is often designed to withstand high loads while being easy to operate and maintain. The correct hanging method can not only increase the electroplating speed and production volume, but also minimize the need for defects and post-processing, save costs and improve the overall quality of the final product.

[0003] However, if a fixture loaded with a large number of workpieces needs to be hung up, the operator needs to expend a lot of energy to lift it. However, the conveyor rack for hanging the fixture loaded with a large number of workpieces cannot adjust the height of the hanging position, which means that the operator cannot save more energy to lift the fixture loaded with a large number of workpieces.

[0004] Therefore, an electroplating suspension structure is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an electroplating processing suspension structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The electroplating processing suspension structure includes two bases, a hydraulic cylinder vertically fixedly connected to the base, a sliding rod slidably connected to the base and located above the hydraulic cylinder, a top frame fixedly connected to the sliding rod, and a rotating component arranged on the top frame. The two bases are fixedly connected with a slide groove with an open top surface and arranged vertically. Control component one and control component two are respectively embedded in the two slide grooves. The control component one and control component two can respectively control the rise and fall of the hydraulic cylinder.

[0008] Preferably, a powered light emitting diode is fixedly connected to the side wall of the base, and the control component 1 and the control component 2 can receive light from the light emitting diode. When the control component 1 or the control component 2 is located in the slide groove, the control component 1 and the control component 2 are powered on.

[0009] Preferably, the control component 1 is provided with a photoelectric sensor 1, the control component 2 is provided with a photoelectric sensor 2, and the photoelectric sensor 2 is coupled with a NOT gate circuit, the control component 1 and the control component 2 both include a NAND gate circuit, an operational amplifier, a control circuit, a switching circuit, a controller, and a button switch, the two input ends of the NAND gate circuit are respectively coupled with the output end of the photoelectric sensor 1 and the output end of the NOT gate circuit, the output end of the NAND gate circuit is coupled with the input end of the operational amplifier, the output end of the operational amplifier is coupled with the input end of the control circuit, the control circuit controls the controller to be powered on through the switching circuit, and the button switch is connected in series to the path where the controller is located.

[0010] Preferably, the control circuit is a 555 time base chip, the switch circuit is a triode switch, and the controller is a single chip microcomputer.

[0014] Preferably, a plurality of reinforcing rods are fixedly connected between the sliding rod and the top frame.

[0015] The utility model has the following beneficial effects:

[0016] When using the utility model, the control of the lowering of the top frame is extremely simple: first, remove the control component 2. This action will cause the photoelectric sensor 2 on the component 2 to lose the induction of the light from the light-emitting diode, and then output a low-level signal to the NOT gate circuit. The NOT gate circuit responds to this signal and changes to a high level. The photoelectric sensor 1 continues to sense the light emitted by the diode and maintains a high-level signal output. The combined signal of the two is processed by the NAND gate circuit and converted into a low-level signal. After amplification by the operational amplifier, it is transmitted to the 555 time base chip, which controls the triode switch path to power on the controller. After that, the operator only needs to press a button to control the hydraulic cylinder to drive the top frame to descend through the cooperation of the wireless transmitter and the receiver. As the sliding rod slides down in the base, the top frame and the rotary component move downward synchronously, which makes it easy for the operator to easily hang the fully loaded fixture at a lower height.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Electroplating processing suspension structure, such as Figure 1As shown, it includes two bases 1, a hydraulic cylinder vertically fixedly connected to the base 1, a sliding rod 5 slidably connected to the base 1 and located above the hydraulic cylinder, a top frame 6 fixedly connected to the sliding rod 5, and a swivel assembly arranged on the top frame 6, and a plurality of reinforcing rods 7 are fixedly connected between the sliding rod 5 and the top frame 6, as shown in FIG. Figure 2 As shown, two bases 1 are fixedly connected with a slide groove 2 with an open top and arranged vertically, and a control component 1 3 and a control component 2 4 are respectively embedded in the two slide grooves 2. The control component 1 3 and the control component 2 4 can respectively control the hydraulic cylinder to rise and fall.

[0025] like Figure 3 and 4 As shown, the rotary assembly includes a driving motor 8 fixedly connected to the top frame 6, a driving sprocket 9 fixedly connected to the output shaft of the driving motor 8, a driven sprocket 12 rotatably connected to the top frame 6, a chain 10 transmission-connecting the driving sprocket 9 and the driven sprocket 12, and a plurality of connecting plates 11 fixedly connected to the chain 10, and the connecting plates 11 are provided with holes for hooks to pass through.

[0026] A light emitting diode 13 is fixedly connected to the side wall of the base 1, and the control component 1 3 and the control component 2 4 can receive light from the light emitting diode 13. When the control component 1 3 or the control component 2 4 is located in the chute 2, the control component 1 3 and the control component 2 4 are energized. The specific structures of the control component 1 3 and the control component 2 4 are as follows:

[0027] like Figure 5 As shown, control component 1 3 and control component 2 4 include a housing, a photoelectric sensor 1 14 is arranged on the housing of control component 1 3, a photoelectric sensor 2 15 and a NOT gate circuit 16 coupled thereto are arranged on the housing of control component 2 4, and control component 1 3 and control component 2 4 also include a NAND gate circuit 1716, an operational amplifier 18, a control circuit 19, a switch circuit 20, a controller 21, and a button switch 23, and the above components are all arranged in the housing.

[0028] The two input ends of the NAND gate circuit 1716 are coupled to the output end of the photoelectric sensor 14 and the output end of the NOT gate circuit 16 respectively. The output end of the NAND gate circuit 1716 is coupled to the input end of the operational amplifier 18. The output end of the operational amplifier 18 is coupled to the input end of the control circuit 19. The control circuit 19 controls the controller 21 to be powered on through the switch circuit 20. The control circuit 19 is a 555 timing chip. The output end of the operational amplifier 18 is connected to the 2nd pin of the 555 timing chip. The switch circuit 20 is a transistor switch. The 3rd pin of the 555 timing chip is connected to the base of the transistor switch. The collector of the transistor switch is connected to the power supply. The emitter of the transistor switch is connected to the controller 21 and then to the ground. The controller 21 is a single-chip microcomputer, and the button switch 23 is connected in series to the path where the controller 21 is located.

[0029] It also includes a wireless generator 22 and a wireless receiver that are communicatively connected. The wireless receiver is coupled to the hydraulic cylinder, and the wireless generator 22 is coupled to the controller 21 .

[0030] When the utility model is used, if it is necessary to control the top frame 6 to descend, it is only necessary to remove the control component 2 4, so that the photoelectric sensor 2 15 on the control component 2 4 can no longer receive the light emitted by the light-emitting diode 13, thereby generating a low-level signal to the NOT gate circuit 16, and the NOT gate circuit 16 will convert it into a high-level signal. Since the photoelectric sensor 14 continues to receive the light from the light-emitting diode 13, it continues to output a high-level signal. After the two high-level signals are given to the NAND gate circuit 1716, it will output a low-level signal to The operational amplifier 18 is amplified instead of being disconnected and no longer sending signals until the low-level signal is transmitted to the 555 time base chip, which controls the transistor switch path, and then the controller 21 is powered. At this time, the operator only needs to press the button switch 23 to enable the controller 21 to control the hydraulic cylinder to descend through the wireless generator 22 and the wireless receiver. The sliding rod 5 will slide downward in the base 1, and then drive the entire top frame 6 and the rotary assembly to move downward together. In this way, the operator can hang the fixture loaded with a large number of workpieces on the hook at a lower level. The connecting piece 11 is placed on the connecting piece 11, and to ensure that the connecting piece 11 is fully hung, it is only necessary to control the driving motor 8 to drive the active sprocket 9 to rotate. Once the active sprocket 9 rotates, it will drive the driven sprocket 12 to rotate through the chain 10 transmission, so the entire chain 10 will rotate, thereby driving each connecting piece 11 to move together in the length direction of the chain 10, which is convenient for the operator to perform the hanging action. If it is necessary to make the top frame 6, the rotating component, and the clamp rise, the operator needs to put the control component 2 4 back into the slide groove 2 so that the photoelectric sensor 2 15 is connected again. Control component 13 can be taken out only after receiving the light from the light-emitting diode 13. Otherwise, when both control component 13 and control component 24 are not in the slide slot 2, the photoelectric sensor 14 will send a low-level signal, and the NAND gate circuit 16 will send a high-level signal, and the NAND gate circuit 1716 cannot be punished, which means that the controller 21 will inevitably be unable to power on. When control component 24 is in the slide slot 2, the operator can remove control component 13 and complete the lifting of the hydraulic cylinder in the above manner, so that it pushes the sliding rod 5, the top frame 6, the rotating assembly and the clamp to move upward.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
