Description

Technical Field

[0001] This utility model relates to the field of diode manufacturing technology, specifically to a splash-proof material guiding mechanism for a diode pressing device. Background Technology

[0002] Semiconductor diodes are frequently used in electronic circuits. They play an important role in many circuits and are one of the earliest semiconductor devices. They are commonly used in circuits for rectification, isolation, voltage regulation, polarity protection, encoding control, frequency modulation, and noise reduction. Their applications are very wide. In the process of diode manufacturing, the semi-finished products that have undergone testing, polarization, and inkjet printing need to be press-fitted.

[0003] Existing cylindrical diode press-fitting devices have a problem: because one side of the concave opening is not sealed, the cylindrical diodes are prone to splashing out from the unsealed side of the concave opening under the pressure of the press-fitting device. This not only wastes materials but also poses a safety hazard. Furthermore, when the cylindrical diodes are being fed into the press-fitting device, they may pile up and break under the pressure of the press-fitting device. Utility Model Content

[0028] An adsorption pad 27 is provided on the inner side of the pressing groove 26. A slider 25 is slidably connected to the inner sides of the front and rear sides of the upper part of the internal thread block 14. A baffle 5 is fixedly connected to the top of the slider 25. A fixed cylinder 12 is fixedly connected to the bottom of the first bracket 2 outside the piston rod of the pressing device 1.

[0029] A guide trough 3 is fixedly connected to the lower right side of the fixed cylinder 12. A vertical plate 17 is slidably connected in the gap between the fixed cylinder 12 and the guide trough 3. A magnetic strip 21 is fixedly connected to the top of the vertical plate 17. A second electromagnet 19 is installed on the right side of the fixed cylinder 12 above the magnetic strip 21 via a first fixing frame 20. A PLC controller 28 is installed on the front side of the base 6.

[0030] Specifically, T-shaped grooves are opened on the front and rear sides of the upper part of the internal thread block 14 in the horizontal direction. The slider 25 is T-shaped, and the clearance between the slider 25 and the groove is ≤0.2mm. The gap between the fixed cylinder 12 and the guide groove 3 is 17mm thick + 0.5mm, and extends through the outlet section of the guide groove 3 in the height direction. The vertical plate 17 slides up and down along the gap for 10-15mm to accommodate the diode length. The height of the baffle 5 is ≥1.5 times the depth of the pressing groove 26, i.e., ≥15mm, and the top extends 8-10mm beyond the upper surface of the carrier belt 9. The angle between the guide groove 3 and the horizontal plane is 25°-35°, and the groove width is 1-2mm larger than the diode diameter. For example, if the diode diameter is 5mm...

The sliding groove of the internal thread block 14 is provided with limit protrusions at both ends. The sliding stroke of the slider 25 is 50-80mm, covering the installation area of ​​the material carrier belt 9.

The PLC controller 28 adopts a metal shielded shell, and the electromagnetic compatibility complies with GB / T 17626.2-2018. The electromagnet coil is connected in parallel with a freewheeling diode to eliminate electromagnetic interference during switching.

[0031] Please refer to Figure 3 to Figure 5 The base 6 has a first bracket 2 fixedly connected to the middle of the front and rear sides. A pressing device 1 is installed on the top of the first bracket 2. A vacuum generator 16 is installed at the lower end of the piston rod in the downward direction of the pressing device 1. A corrugated suction cup 22 is installed at the lower air port of the vacuum generator 16.

[0032] Specifically, the lateral deviation between the center of the corrugated suction cup 22 and the center of the pressing groove 26 is ≤0.3mm, which is achieved by the positioning boss at the lower end of the fixed cylinder 12 cooperating with the groove of the material carrier belt 9.

[0033] Please refer to Figure 1 and Figure 3 A second bracket 4 is fixedly connected to the lower right end of the guide trough 3, and the lower end of the second bracket 4 is fixedly connected to the base 6.

[0034] Please refer to Figure 3 to Figure 4 A first electromagnet 11 is installed on the lower left side of the fixed cylinder 12 via a second fixed bracket 24. A magnetic strip 21 is slidably connected to the inner right side of the second fixed bracket 24. A horizontal plate 18 is fixedly connected to the right side of the magnetic strip 21. The outer side of the horizontal plate 18 is slidably connected to the fixed cylinder 12.

[0035] Specifically, the rated current of the first electromagnet 11 is 0.5-1A, and the magnetic pole switching time is ≤0.2s; the magnetic strip 21 is a neodymium iron boron permanent magnet with a residual magnetism ≥1.2T and an attraction force with the electromagnet ≥5N, ensuring reliable movement of the horizontal plate 18. Two parallel linear guide rails are set on the inner wall of the fixed cylinder 12, and matching sliders 25 are installed on both sides of the horizontal plate 18. The straightness error of the guide rails is ≤0.1mm / m. The attraction force of the first electromagnet 11 is greater than the friction force between the horizontal plate 18 and the fixed cylinder 12, so as to achieve precise positioning of the horizontal plate 18.

[0036] Please refer to Figure 1 to Figure 2 An infrared transmitter 10 is provided on the lower part of the front wall of the fixed cylinder 12, an infrared receiver 13 is provided on the lower part of the rear wall of the fixed cylinder 12, and a contact point 23 is provided on the left side of the upper inner wall of the fixed cylinder 12.

[0037] Specifically, the detection distance between the infrared transmitter 10 and the infrared receiver 13 is ≤50mm, the response time is ≤0.1s, and the installation height is equal to the center of the diode diameter.

[0038] Please refer to Figure 1 to Figure 6 The PLC controller 28 is electrically connected to contact 23, the PLC controller 28 is electrically connected to infrared transmitter 10, the PLC controller 28 is electrically connected to infrared receiver 13, the PLC controller 28 is electrically connected to first electromagnet 11, the PLC controller 28 is electrically connected to second electromagnet 19, the PLC controller 28 is electrically connected to pressing device 1, and the PLC controller 28 is electrically connected to motor 7.

[0039] In use, the baffle 5 is moved on the internal threaded block 14, exposing the top of the internal threaded block 14. Then, the carrier belt 9 is installed and placed. Next, a diode is placed on the guide groove 3. The diode will slide down the inclination of the guide groove 3. Then, the vertical plate 17 will block the diode. Then, the pressing device 1, motor 7, infrared transmitter 10, first electromagnet 11, infrared receiver 13, second electromagnet 19, and PLC controller 28 are started. The motor 7 drives the threaded rod 15 to rotate. Utilizing the threaded connection between the threaded rod 15 and the internal threaded block 14, the internal threaded block 14 is moved laterally. The internal threaded block 14 drives the carrier belt 9 to move, aligning the pressing groove 26 on the carrier belt 9 with the lower outlet of the fixed cylinder 12. Then, the infrared transmitter 1... Infrared light emitted by the infrared emitter 10 is received by the infrared receiver 13. The infrared receiver 13 transmits an electrical signal to the PLC controller 28. The PLC controller 28 controls the second electromagnet 19 to attract the magnetic strip 21. At this time, the upper part of the second electromagnet 19 is the N pole and the lower part is the S pole, and the upper part of the magnetic strip 21 is the N pole and the lower part is the S pole. Consequently, the magnetic strip 21 moves the vertical plate 17 upward, causing the diode to enter the fixed cylinder 12 and fall onto the horizontal plate 18. At this time, the infrared light emitted by the infrared emitter 10 is blocked by the diode, and the infrared receiver 13 does not receive the infrared signal. The infrared receiver 13 transmits this signal to the PLC controller 28, and the PLC controller 28 controls the second electromagnet 19 to repel the magnetic strip 21. At this time, the upper part of the second electromagnet 19 is the S pole and the lower part is the S pole. The bottom of the magnetic strip 21 is the N pole, and the top of the magnetic strip 21 is the N pole, and the bottom is the S pole. The magnetic strip 21 then moves the vertical plate 17 downwards, blocking the subsequent diode. Simultaneously, the pressing device 1 moves the vacuum generator 16 and the corrugated chuck 22 downwards, bringing the corrugated chuck 22 into contact with the diode. The vacuum generator 16 activates, causing the corrugated chuck 22 to vacuum-adsorb the diode. The PLC controller 28 controls the first electromagnet 11 to adsorb the magnetic strip 21 connected to the horizontal plate 18. At this point, the left side of the first electromagnet 11 is the N pole, and the right side is the S pole. The left side of the magnetic strip 21 is the N pole, and the right side is the S pole. The magnetic strip 21 then moves the vertical plate 17 to the left. Finally, the pressing device 1, through the vacuum generator 16 and the corrugated chuck 22, moves the diode further downwards. The device moves downward to press the diode onto the pressing groove 26. The baffle 5 prevents the diode from splashing onto the human body. The adsorption pad 27 can adsorb the diode. After pressing, the pressing device 1 drives the vacuum generator 16 and the corrugated suction cup 22 to move upward until they touch the contact point 23. Then the contact point 23 transmits a signal to the PLC controller 28. The PLC controller 28 controls the first electromagnet 11 to repel the magnetic strip 21 connected to the horizontal plate 18. At this time, the left side of the first electromagnet 11 is the S pole and the right side is the N pole. The left side of the magnetic strip 21 is the N pole and the right side is the S pole. In turn, the magnetic strip 21 drives the vertical plate 17 to move to the right. At the same time, it controls the infrared transmitter 10 to emit an infrared signal to the infrared receiver 13, and then performs subsequent actions.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
