Description

Technical Field

[0001] The present invention relates to the field of electronic component manufacturing equipment, and specifically to an automatic feeding device for sliding switch shrapnel. Background Art

[0002] A sliding switch is a common electronic component widely used in fields such as home appliances and electronic devices. The shrapnel inside it is a core functional component responsible for realizing the connection and disconnection of the circuit. During the production of sliding switches, the installation of the shrapnel is an important and complex process, which directly affects the functional reliability and production efficiency of the product; In traditional sliding switch shrapnel feeding devices, the shrapnel is usually separated from the tape by a punching mechanism and then grabbed by a manipulator and transported to the installation position of the plastic part; However, in the existing technology devices, during the separation and transportation of the shrapnel, the shrapnel is prone to winding or sticking due to electrostatic action or mechanical interference of the tape. This not only affects the smooth progress of subsequent installation but also requires manual intervention or complex mechanical separation mechanisms to solve the problem of shrapnel winding; secondly, during the tape transmission process, due to the friction between the tape and the surface of the device, static electricity often generates. The debris generated during the processing is attracted by the static electricity and approaches the shrapnel, thus affecting the punching and grabbing accuracy of the shrapnel; due to the flexibility of the tape and the vibration during the transmission process, the tape may tilt or shift, resulting in errors in the punching position and grabbing action.

The control assembly 14 includes a mounting plate 1401. The mounting plate 1401 is arranged on the first mounting frame 6. Two groups of pulleys 1403 and a slide rail 1407 are arranged on the mounting plate 1401. A transmission belt 1404 is connected between the two groups of pulleys 1403.

A manipulator 1409 is arranged on the control board 1406. A first motor 1402 is arranged on the mounting plate 1401. The output end of the first motor 1402 is fixedly connected to one of the pulleys 1403; The function of the auxiliary fixing device 9 is to assist in clamping the plastic part 3 on the placing block 2 to ensure the stability of the plastic part 3 during the installation process of the elastic piece 4. The mounting plate 1401 supports the entire operating system. Two sets of pulleys 1403 are connected by a transmission belt 1404.

[0022] Please refer to the attached Figure 3 and the attached Figure 6 As shown in the figure, an anti-elastic-piece winding mechanism 15 is provided on the operating component 14. The anti-elastic-piece winding mechanism 15 includes a jet pipe 1501. The jet pipe 1501 is arranged on the manipulator 1409 in the operating component 14. A shunt pipe 1502 is arranged on the jet pipe 1501, and a plurality of air flow nozzles 1503 are arranged on the shunt pipe 1502. An air pump 1504 is arranged on the manipulator 1409 in the operating component 14. The output end of the air pump 1504 is connected to the jet pipe 1501 through a pipeline. The high-pressure air flow released by the jet pipe 1501 on the manipulator 1409 solves the problem of elastic piece winding. The jet pipe 1501 disperses and transmits the compressed air flow to multiple directions through the shunt pipe 1502, and the air flow finally sprays out from the multiple air flow nozzles 1503, so as to quickly separate the wound elastic pieces 4. The air pump 1504, as the power source of the jet pipe 1501, transports compressed air to the jet pipe 1501 through a pipeline and adjusts the intensity and direction of the air flow according to the detected winding situation of the elastic pieces 4. By analyzing the module to judge the winding degree of the two ends of the elastic pieces 4, according to the winding degree of the elastic pieces 4, the central control system adjusts the shunt ratio in the shunt pipe 1502 and the working power of the air pump 1504, and the distributed air flows spray out from different air flow nozzles 1503 respectively, and the elastic pieces 4 in the corresponding directions are separated.

[0023] Experiments are carried out based on the basic theories of fluid dynamics and air pump performance, and the following data are obtained. The data are based on the working principle of the system and the required fluid mechanics characteristics, and factors such as the material of the elastic piece, elastic modulus, and working characteristics of the air pump are considered.

[0024] Assume the winding degree W: 0% represents completely unwound, and 100% represents completely wound; the shunt ratio F: The relationship between the shunt ratio and the winding degree is assumed to be exponential decay. That is, as the winding degree increases, the shunt ratio decreases rapidly; the air pump power P: The air pump power is affected by the flow resistance. As the winding degree increases, the flow resistance increases, so a greater power is required to maintain the air flow.

[0025] Relationship between the shunt ratio and the winding degree: F = F0·e -kW ; where F0 is the shunt ratio when there is no winding (i.e., 100%), k is the shunt decay coefficient, and W is the winding degree.

[0026] Relationship between the air pump power and the winding degree: P = P0·(1 + αW); where P0 is the air pump power when there is no winding, and α is the air pump power increase coefficient.

[0027] Given the initial parameters: the shunt ratio F0 = 100% when there is no winding; the air pump power P0 = 50W when there is no winding; the shunt decay coefficient k = 0.1; the air pump power increase coefficient α = 0.3. Based on the above assumptions, the shunt ratio and the air pump power at different winding degrees can be calculated.

[0028] Taking W = 0%, 25%, 50%, 75%, 100% as examples, the shunt ratio and the air pump power at each winding degree are calculated, and the calculation results are shown in the following table. Winding degree (%) Diversion ratio (%) Air pump power (W) 0 100.00 50.00 25 8.21 53.75 50 0.67 57.50 75 0.06 61.25 100 0.0045 65.00

[0029] As the winding degree increases, the shunt ratio shows exponential decay. For example, when the winding degree is 25%, the shunt ratio has dropped to about 8.21%, and when the winding degree is 50%, the shunt ratio is only 0.67%. This decay trend indicates that the fluid distribution of the system is strongly affected by the winding degree, and when the winding degree is almost 75%, the shunt ratio drops to nearly zero.

[0030] The air pump power increases linearly with the increase of the winding degree. When the winding degree is 100%, the air pump power is 65W, which is higher than that when there is no winding (50W). This increase indicates that as the flow resistance increases, the air pump requires more power to maintain the air flow.

[0031] If the shunt ratio drops too fast, the value of k can be adjusted to slow down the decay rate. For example, adjusting k to 0.05 or less can make the shunt ratio drop more gently. By selecting a more efficient air pump or adjusting the air path design, the increase in the air pump power can be reduced. Appropriately select a lower increase coefficient α to help slow down the increase in power demand.

The pushing device 16 is responsible for pushing the tape to the punching station, while the belt pressing device 17 presses the tape tightly to ensure that it does not shift during punching. The conductive component 18 is used to remove the static electricity generated by friction during the transmission of the tape. By contacting the tape through the contact 1801, the static electricity is conducted to the conductive block 1803 through the electrostatic tube 1802, and finally the static electricity is discharged through the grounding wire 1804, thus avoiding the interference of static electricity on the installation accuracy of the shrapnel.

[0036] Please refer to the appendix Figure 1 , the appendix Figure 2 , the appendix Figure 8 and the appendix Figure 9, a vision sensor 21 is provided on the auxiliary fixing device 9, an operation monitor 22 is provided on the second mounting bracket 7, and an infrared sensor 23 is provided on the slider three 2002 in the width adjustment mechanism 20. The data collected by the vision sensor 21, the operation monitor 22, and the infrared sensor 23 is transmitted to the central control system.

[0037] Please refer to the appendix Figure 12 , the central control system includes: Acquisition module: It is used to transmit the data collected by the vision sensor 21, the operation monitor 22, and the infrared sensor 23 to the central control system; Analysis module: It analyzes the data collected in the central control system through the data processing unit; Drive module: It drives the air pump 1504 and the second motor 1906 through the analyzed information.

[0038] Working principle: The conveyor belt 1 drives the placement block 2 to move. There is a plastic part 3 to be processed on the placement block 2. When the plastic part 3 to be processed moves to the specified position, the hydraulic push rod 504 on the mounting table 505 extends outwards, driving the limit block 503 to move. The limit post 502 on the limit block 503 enters the limit groove 501 to fix the placement block 2. The tape enters the loading table 8 under the push of the pushing device 16, and then the tape pressing device 17 presses the tape; Since the tape generates static electricity when rubbing against the loading table 8 during the pushing process by the pushing device 16, when the tape pressing device 17 presses the tape, the contact head 1801 will contact the tape, and the static electricity on the tape is attracted by the contact head 1801 and then removed by being conducted to the grounding wire 1804 through the static electricity tube 1802; During the process of pushing the strip by the pushing device 16, according to the size of the strip, the motor three 2010 on the width-adjusting plate 2001 is started. The motor three 2010 rotates the worm 2009. Through the meshing relationship between the worm 2009 and the worm wheel 2008, the rotating shaft 2005 rotates. The gear three 2007 rotates at the same frequency as the rotating shaft 2005. Since the gear two 2006 meshes with the gear three 2007, the gear two 2006 also rotates. At this time, the gear one 2004 on the gear three 2007 and the gear two 2006 also rotates. The gear one 2004 on the gear three 2007 and the gear two 2006 successively contact the rack 2003, and the distance between the slider three 2002 is adjusted through the meshing relationship, so that the infrared sensor 23 on the slider three 2002 conforms to the size of the strip. When the infrared sensor 23 receives the blocking information, the central control system determines that the strip is tilted at this time. The central control system starts the motor two 1906. After the motor two 1906 starts, the screw 1904 rotates. The rotating screw 1904, through the thread relationship with the nut 1905, makes the slider two 1903 approach the strip, and the straightening plate 1907 on the slider two 1903 straightens the strip; When the strip enters the feeding table 8, the upper die 10 and the lower die 11 are used to remove the elastic piece 4 from the strip. The manipulator 1409 grabs the elastic piece 4. Subsequently, the motor one 1402 rotates the pulley 1403, and the transmission belt 1404 also moves accordingly. The connecting block 1405 on the transmission belt 1404 moves accordingly. The operating plate 1406 is driven by the connecting block 1405. During the movement of the operating plate 1406, the slider one 1408 moves along the track of the slide rail 1407. The manipulator 1409 moves the elastic piece 4 above the placing block 2. Subsequently, the auxiliary fixing device 9 clamps the plastic part 3 on the placing block 2, and the visual sensor 21 on the auxiliary fixing device 9 detects the elastic piece 4 of the manipulator 1409. When the elastic piece 4 is wound, the visual sensor 21 detects the winding information and, according to the analysis by the analysis module in the central control system, determines the position where the elastic piece 4 is wound. The central control system controls the air pump 1504 to start, pressurizes and conveys the air to the air injection pipe 1501, and then transmits the air flow to the air flow nozzles 1503 at the corresponding positions through the shunt pipe 1502. If the elastic pieces 4 at both ends are wound, the visual sensor 21 transmits the winding information of the elastic piece 4 to the analysis module. Through the analysis module, the winding degree of the elastic pieces 4 at both ends is judged. According to the winding degree of the elastic piece 4, the central control system adjusts the shunt ratio in the shunt pipe 1502 and the working power of the air pump 1504. The distributed air flows are ejected from different air flow nozzles 1503 respectively, and the elastic pieces 4 in the corresponding directions are separated; During the processing, the operation monitor 22 will monitor the operation of the device in real time, and the waste will be discharged through the discharge pipe 12 and then enter the collection box 13. After the processing is completed, since there will be debris between the upper die 10 and the feeding table 8, this part of the debris will be attracted to the tape due to the static electricity generated by the tape. After the processing is completed, the air extractor 2404 is started to change the air pressure in the dust collection box 2402, generating negative pressure, and this part of the debris is sucked into the dust collection bag 2403 through the pipeline and the dust suction hood 2401.
