Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve manufacturing technology, and more specifically, to an impedance detection component based on an electromagnetic coil, an automatic detection architecture, and a tin-dipping device. Background Technology

[0002] Currently, the electromagnetic coil, as a crucial component of a solenoid valve, works by generating an electromagnetic field when a working voltage is applied to the coil. This field causes the moving iron core of the solenoid valve to attract, thereby controlling the opening and closing of the circuit. Since the coil is an energized device, its input terminal typically requires either a flexible wire connection or a hard connection via pin terminals to energize the entire solenoid valve.

[0003] In the prior art, for electromagnetic coils with pre-installed pin terminals on the coil frame, after the enameled wire winding is wound, the beginning and end of the enameled wire winding need to be further wound onto the two pins of the coil frame respectively. At the same time, in combination with the overall shape design requirements of the solenoid valve, the pins of the electromagnetic coil need to be bent at 90°, and then the winding leads and pins need to be soldered together.

[0004] Under current conventional processes, the bending process of leads usually requires manual operation of equipment such as presses and bending dies, while the soldering process of leads also requires manual operation of tin-dipping equipment. After tin-dipping, resistance testing instruments are also required to test the resistance of conductive wires. Only in this way can the workload of one shift be completed. The overall work efficiency is low and the labor cost is relatively high. At the same time, due to mass production, the operators' working hours are long, and the personnel turnover is also a factor, making it difficult to avoid human error in the above-mentioned processes, which can easily lead to the outflow of defective products.

[0080] In one optional implementation, the positioning and loading seat 32 has a vertical limiting post and a corresponding retaining protrusion located on the outer side of the vertical limiting post, so as to stabilize and limit the electromagnetic coil. At the same time, the vertical limiting post can be used to facilitate the extraction of the electromagnetic coil, thereby completing the fluxing and tinning process.

The kinetic energy output end of the first flux lifting cylinder 512 is connected to the flux rotation motor 513, and the kinetic energy output end of the flux rotation motor 513 is connected to the base of the flux pneumatic gripper 514. This allows the flux translation cylinder 511 and the first flux lifting cylinder 512 to effectively drive the flux pneumatic gripper 514 to achieve horizontal and vertical displacement.

This is used to effectively drive the tin-dipping pneumatic gripper 614 to achieve horizontal and vertical displacement based on the output kinetic energy of the tin-dipping translation cylinder 611 and the tin-dipping lifting cylinder 612. In this way, the tin-dipping pneumatic gripper 614 can grasp the electromagnetic coil that has completed the flux dipping process, and can further move the electromagnetic coil to the position above the molten solder reservoir assembly 63.

[0089] As another preferred embodiment, the pin immersion tin structure 6 further includes a molten solder scraping assembly 62, which includes a scraping translation cylinder 621, a directional guide rail slide 622, a scraping lifting cylinder 623, and an extension scraper 624.

[0091] As another preferred embodiment, please refer to [the relevant documentation]. Figure 7The tin-immersion transfer assembly 61 also includes a laser ranging assembly 615. The base of the laser ranging assembly 615 is fixedly mounted on the top surface of the positioning base structure 1, and the detection end of the laser ranging assembly 615 is vertically positioned above the tin-immersion tank 632. This allows the laser ranging assembly 615 to monitor the molten solder level inside the tin-immersion furnace 631 in real time from the tin-immersion tank 632. When the molten solder level slowly decreases due to solder consumption, the laser ranging assembly 615 can send the liquid level information to the electrical control structure 9 in real time. After calculation, the electrical control structure 9 further outputs command information to the intelligent lifting module. The intelligent lifting module makes real-time adjustments to the lifting height of the tin-immersion lifting cylinder 612, thereby realizing the automatic adjustment and compensation function of the descent height, thus ensuring that the coil pins are immersed in the molten solder at the same depth and ensuring the consistency of tin-immersion quality.

[0092] More preferably, the laser ranging component 615 is set with a standard liquid level height value and a maximum liquid level drop value parameter, so that when the liquid level drop value exceeds the set maximum value, the electronic control structure 9 outputs a command to control the alarm prompt and control the stop of operation until solder is added and the component is unlocked to start working again.

The upper and lower limit alarm resistor 72 has two test probes 73, and these two test probes 73 are interchangeably and switchably configured to correspond with two bent pins of one set of electromagnetic coils. This allows the horizontal telescopic cylinder 71 to extend and drive the test probes 73 to contact the bent pins of the electromagnetic coils, thereby enabling the upper and lower limit alarm resistor 72 to automatically detect the impedance of the electromagnetic coils.

The material handling and transfer component 81 is provided with a movable material handling and extraction end. The extraction end of the material handling and transfer component 81 can be linearly moved and located between one of the positioning loading seats 32 and the upstream end of the material handling conveyor belt component 82. The NG material handling component 83 is located on the linear displacement path of the extraction end of the material handling and transfer component 81. This allows the electromagnetic coils that have completed impedance detection to be sequentially transported and moved by the material handling and transfer component 81, and can be transported and moved to the material handling conveyor belt component 82 or the NG material handling component 83 according to the detection and judgment result of the electronic control structure 9.

[0095] It should be noted that the electrical control structure 9 includes a power supply module, a control module, and an intelligent lifting module connected by a circuit. The control module can be selected, but is not limited to, a single-chip microcontroller control board of model AT80C51 or a microcontroller of model STM32. The control output terminal of the control module is connected to the input terminal of a relay through a circuit. The output terminal of the relay is connected to the intelligent lifting module, the feeding conveyor belt assembly 21 and the feeding transfer assembly 22 in the feeding and handling structure 2, the drive turntable assembly 31 in the loading turntable structure 3, the coil clamping cylinder 421, the pin bottom support cylinder 431 and the bending and stamping cylinder 441 in the pin bending structure 4, the flux translation cylinder 511, the first flux lifting cylinder 512, the flux indexing motor 513, the flux pneumatic gripper 514 and the second flux dipping structure 5. The soldering lifting cylinder 522, the solder dipping translation cylinder 611, the solder dipping lifting cylinder 612, the solder dipping indexing motor 613, the solder dipping pneumatic gripper 614, the scraping translation cylinder 621 and the scraping lifting cylinder 623 in the pin immersion structure 6, the horizontal telescopic cylinder 71 in the impedance detection structure 7, and the unloading transfer component 81, the unloading conveyor belt component 82 and the NG unloading component 83 in the unloading and handling structure 8 are connected by circuits; the material laser detection component 23 in the loading and handling structure 2, the liquid level detection component 524 in the flux dipping structure 5, the laser ranging component 615 in the pin immersion structure 6, and the upper and lower limit alarm resistor 72 in the impedance detection structure 7 are also connected by circuits to the control input terminal of the control module, so as to complete the automated operation control of the overall architecture function.

[0096] This utility model embodiment also provides an automatic bending and tinning method based on the above-described impedance detection component, automatic detection architecture, and tinning equipment using an electromagnetic coil, specifically including the following steps:

[0097] The electromagnetic coil to be used is installed onto the feeding conveyor assembly 21 in the feeding and handling structure 2 with its pins facing outwards. The start button is pressed, and the feeding conveyor assembly 21 starts running. After the material laser detection assembly 23 detects the presence of the electromagnetic coil on the feeding conveyor assembly 21, the feeding transfer assembly 22 extracts the electromagnetic coil and transports it to the positioning loading seat 32 of the loading turntable structure 3. Then, the feeding conveyor assembly 21 runs again, transporting the electromagnetic coil to the feeding waiting position. This cycle repeats until the material laser detection assembly 23 can no longer detect the coil corresponding to the feeding conveyor assembly 21. At this point, the feeding conveyor assembly 21 stops operating, waiting to place the electromagnetic coil onto the feeding conveyor assembly 21 again. At this time, several sets of electromagnetic coils are respectively placed in several sets of positioning loading seats 32, with all the pins of the electromagnetic coils facing outwards.

[0098] Several sets of electromagnetic coil pins are sequentially rotated to correspond to the pin bending structure 4 for bending process. After the bent electromagnetic coil is rotated into place by the drive turntable assembly 31, the coil body is first pressed and fixed by the coil pressing assembly 42 in the pin bending structure 4. Then, the pin bottom support cylinder 431 in the pin bottom support assembly 43 drives the bottom support pad 433 to move upward and make the bottom support pad 433 contact the coil pin upward. Then, the bending and stamping cylinder 441 in the bending and stamping assembly 44 drives the bending and stamping head 443 to move downward. The stamping head 443 presses and contacts the electromagnetic coil pin and bends the electromagnetic coil pin downward to form shape.

[0099] After the electromagnetic coil leads are bent and shaped, under the control of the electronic control structure 9, the components of the lead bending structure 4 are withdrawn in sequence, and the electromagnetic coil remaining in the loading turntable structure 3 completes the lead bending process.

[0100] Several sets of electromagnetic coil pins that have completed the bending process are sequentially rotated to correspond to the flux dipping structure 5 for fluxing. After the electromagnetic coils to be fluxed are rotated into place by the drive turntable assembly 31, the flux transfer assembly 51 in the flux dipping structure 5 is driven by the first flux lifting cylinder 512 to drive the flux pneumatic gripper 514 to move downward. The flux pneumatic gripper 514 grabs the electromagnetic coils that have completed the bending process on the workstation and lifts the electromagnetic coils upward by the first flux lifting cylinder 512. Then, the flux transfer assembly 51 is driven by the flux translation cylinder 511 to further drive the flux pneumatic gripper 514 and the electromagnetic coils it grabs to move above the flux lifting assembly 52. ​​Then, the flux transfer assembly 51 is driven by the flux transfer motor 513 to drive the flux pneumatic gripper 514 to rotate, so that the fluxing part of the electromagnetic coil pins is facing downward, thus completing the fluxing positioning of the electromagnetic coil pins.

[0101] Further, the second flux lifting cylinder 522 in the flux lifting assembly 52 drives the flux lifting tray 523 and its built-in flux to rise to the position of the electromagnetic coil pin, until the pin of the electromagnetic coil that needs to be tinned is dipped into the flux in the flux lifting tray 523 at a specific height.

[0102] Continue to control the second flux lifting cylinder 522 to drive the flux lifting tray 523 down to its original position, and the flux transfer assembly 51 drives the flux pneumatic gripper 514 to rotate and move, thereby placing the electromagnetic coil back to the loading turntable structure 3, thus completing the flux dipping process of the electromagnetic coil pins.

[0103] In an optional implementation, in a static state, the flux level in the flux storage tank 521 is higher than the upper end of the receiving port of the flux lifting tray 523, thereby ensuring that the flux inside the flux lifting tray 523 is full each time it is lifted, and ensuring that the flux level of the electromagnetic coil pins is consistent.

[0104] Another optional implementation is that the flux lifting component 52 has a liquid level detection function. When the liquid level detection component 524 detects that the liquid level in the flux storage tank 521 is lower than the set value, the whole system alarms and stops working. It can only be unlocked and started working again after flux is added. Specifically, when the liquid level in the flux storage tank 521 drops due to flux consumption, the built-in photoelectric switch of the liquid level detection component 524 cannot sense the liquid level, so its indicator light is lit and a command signal is output. After the system receives the command signal, it stops working, and the external touch screen prompts that the flux liquid level is low and needs to be replenished. After the photoelectric switch recognizes that the replenishment is completed, the indicator light goes out, the output signal disappears, and the system can resume working after reset.

[0105] Several sets of electromagnetic coil pins that have completed the fluxing process are sequentially rotated to correspond to the pin tinning structure 6 for tinning. After the tinned electromagnetic coils are rotated into position by the drive turntable assembly 31, the tinning transfer assembly 61 in the pin tinning structure 6 is driven by the tinning lifting cylinder 612 to move the tinning pneumatic gripper 614 downward. The tinning pneumatic gripper 614 grabs the electromagnetic coils that have completed the fluxing process on the station and lifts the electromagnetic coils upward by the tinning lifting cylinder 612. Then, the tinning transfer assembly 61 is further driven by the tinning translation cylinder 611 to move the tinning pneumatic gripper 614 and the electromagnetic coil it grabs to the top of the molten solder reservoir assembly 63. Then, the tinning transfer assembly 61 is driven by the tinning transfer motor 613 to rotate the tinning pneumatic gripper 614, so that the tinning part of the electromagnetic coil pins faces downward, thus completing the tinning positioning of the electromagnetic coil pins.

[0106] Meanwhile, the molten tin scraping assembly 62 performs a slag removal and cleaning process on the surface of the molten tin by corresponding to the molten tin storage assembly 63. Specifically, the scraping translation cylinder 621 in the molten tin scraping assembly 62 pushes the extended scraper 624 to one end of the molten tin storage assembly 63. Then, the scraping lifting cylinder 623 in the molten tin scraping assembly 62 lowers the extended scraper 624 to the surface of the molten tin. The scraping translation cylinder 621 is then controlled to retract the extended scraper 624 to the other end of the molten tin storage assembly 63 to remove the slag on the surface. After that, the scraping lifting cylinder 623 rises to remove the extended scraper 624 from the surface of the molten tin, thus completing one surface cleaning.

[0107] Further, the immersion lifting cylinder 612, controlled by the electronic control structure 9, drives the immersion pneumatic gripper 614 and the electromagnetic coil pin end it grips to descend. The electromagnetic coil pin end descends with an automatic adjustment and compensation function for the descent height. That is, when the solder liquid level decreases slowly due to immersion consumption, the laser ranging component 615 sends the solder liquid level height feedback to the electronic control structure 9 in real time. After calculation, the electronic control structure 9 controls the descent height of the immersion lifting cylinder 612 to ensure that the electromagnetic coil pin is immersed in the solder liquid at a consistent depth, thereby ensuring the consistency of immersion quality. Thus, the electromagnetic coil pin end descends and is inserted into the internal solder liquid surface of the molten solder storage component 63, so that the electromagnetic coil pin completes the immersion process at a predetermined height.

[0108] The laser ranging component 615 is set with parameters for the standard liquid level height and the maximum liquid level drop. When the liquid level drop exceeds the set maximum value, the whole system will alarm and stop working until the specific solder liquid is refilled before it can be unlocked and immersed in solder again.

[0109] After the tinning process is completed, the pins of several sets of electromagnetic coils are sequentially rotated to correspond to the impedance detection structure 7 for impedance detection. After the electromagnetic coil for impedance detection is rotated into place by the drive turntable assembly 31, the horizontal telescopic cylinder 71 in the impedance detection structure 7 drives the test probe 73 to extend and contact the electromagnetic coil pin. The electronic control structure 9 detects the coil impedance through the upper and lower limit alarm resistor 72. When the measured impedance is within the required range, the upper and lower limit alarm resistor 72 does not alarm. If the system does not receive an alarm signal within the specified time, it is assumed that the coil impedance of this station is qualified and recorded. When the impedance is not within the required range, the upper and lower limit alarm resistor 72 will output an alarm. The system receives the unqualified signal and records the unqualified result.

[0110] According to the system's judgment result, the unloading and handling structure 8 transports the NG products in the inspected electromagnetic coils to the corresponding NG collection container through the unloading and transfer component 81, and transports the qualified products to the unloading conveyor belt component 82. After the transfer, the products are subjected to tinning appearance inspection and stacked in the turnover tray.

[0111] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
