Description

Technical Field

[0001] The present invention relates to a resonator detection and packaging device, and particularly to a crystal oscillator taping machine with an error detection function. Background Art

[0002] In the taping and packaging of quartz crystal resonator products, a product taping machine is usually used. The taping machine can tape products such as patches or electronic components such as crystal resonators and oscillators, facilitating the transportation of products and protecting the products to a certain extent. Currently, the product taping machines on the market all use pneumatic clips for products on a straight track to directly clamp the feeder on the straight track and send the products to the taping track for taping and packaging. During the process, it is easy for the resonator to be placed incorrectly, resulting in problems such as side standing, turning over, and floating. During subsequent taping reel winding or transportation, the resonator is easily damaged, leading to a very high rejection rate of the taping reel. Therefore, during the production process, the manufacturer also needs to specially assign a staff member to observe, which greatly reduces the production efficiency and causes waste of labor. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a crystal oscillator taping machine with an error detection function that can effectively eliminate problems such as side standing and turning over of resonators, thereby improving the production efficiency and the finished product rate.

[0004] The technical solution adopted by the present invention is as follows: The present invention includes a machine table, a rotary vibrating feeding tray, a material taking mechanism, and a film sealing mechanism that are sequentially arranged on the machine table. The rotary vibrating feeding tray is connected to the material taking mechanism through a linear vibrating track. A taping mechanism and a taping groove adapted to the taping mechanism are also arranged on the machine table. The film sealing mechanism is arranged above the taping mechanism. A detection mechanism is also arranged between the film sealing mechanism and the material taking mechanism. The detection mechanism includes a horizontal light source generator, a horizontal light source receiver, and a vertical optical fiber detector. The horizontal light source generator and the horizontal light source receiver are respectively arranged on both sides of the taping groove, and the vertical optical fiber detector is located above the taping groove. The material taking mechanism includes a negative pressure suction head, a progressive conveying device, and a testing device. The progressive conveying device is connected to the linear vibrating track. The testing device is arranged at the starting position of the progressive conveying device. The negative pressure suction head is arranged at the end position of the progressive conveying device through a vertical cylinder. The progressive conveying device includes a feeding groove. Clamping blocks are arranged on both the left and right sides of the feeding groove. A number of concave work positions are evenly arranged on the clamping blocks. A clamping cylinder and a second stepping motor are also arranged below the clamping blocks. The testing device includes a testing pressure plate arranged above the progressive conveying device and a testing probe arranged below the progressive conveying device. Both the testing probe and the testing pressure plate are connected to a testing driving cylinder. The testing probe and the testing pressure plate are both corresponding to the concave work positions in terms of position.

[0005] Further, the taping mechanism includes a carrier tape roller and a take-up tape roller symmetrically arranged on the front and rear sides of the machine table. A first stepping motor is arranged on the take-up tape roller. A taping is connected between the carrier tape roller and the take-up tape roller. The taping is placed in the taping groove and is in sliding fit with the taping groove.

[0006] Furthermore, a number of placing grooves are evenly arranged on the taping. A number of through holes are also arranged on both sides of the taping.

[0007] Still further, a defective product collection box is also arranged between the progressive conveying device and the negative pressure suction head.

[0008] In addition, the film sealing mechanism includes a film sealing roller, a guide shaft group, and a hot pressing knife. The film sealing roller is arranged directly above the taping groove, and the film sealing is transmitted to the taping through the guide shaft group. A third stepping motor is arranged on the film sealing roller. Two hot pressing knives are symmetrically arranged on both sides of the taping groove through a lifting cylinder and protrude into the taping groove.

[0009] Further, the guiding shaft group includes a first guiding shaft fixedly arranged on the machine table and closely attached to the taping. A second guiding shaft is arranged directly above the first guiding shaft. The second guiding shaft and the film sealing roller are arranged on the same horizontal plane. The film for sealing is transmitted to the taping through the second guiding shaft and the first guiding shaft.

[0010] Finally, the film sealing mechanism further includes a perforating roller. Perforating gear discs adapted to the through holes are arranged on the left and right sides of the perforating roller. A fourth stepping motor is arranged on the perforating roller.

[0011] The beneficial effects of the present invention are as follows: First, the test device in the material taking mechanism is used to conduct a functional test on the resonator. The qualified products are transmitted to the lower part of the negative pressure suction head through the progressive transmission device. The negative pressure suction head loads the resonator into the placement groove of the taping, and the unqualified products are directly sent into the unqualified product recycling box by the progressive transmission device. Subsequently, the horizontal light source generator, the horizontal light source receiver, and the vertical optical fiber detector are used to detect the resonator placed in the placement groove to check whether problems such as side standing, floating up, and turning over occur. Finally, film sealing is performed through the film sealing mechanism, and the taping mechanism winds up the taping, completing automatic taping packaging, thereby showing the effects of high qualified rate and high production efficiency.

[0017] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the present invention includes a machine table 1, a rotary vibrating feeder 2, a picking mechanism, and a film sealing mechanism that are sequentially arranged on the machine table 1. The rotary vibrating feeder 2 is connected to the picking mechanism through a linear vibrating track 3. A taping mechanism and a taping groove 4 adapted to the taping mechanism are also arranged on the machine table 1. The film sealing mechanism is arranged above the taping mechanism. A detection mechanism is also arranged between the film sealing mechanism and the picking mechanism. The detection mechanism includes a horizontal light source generator 5, a horizontal light source receiver 6, and a vertical optical fiber detector 7. The horizontal light source generator 5 and the horizontal light source receiver 6 are respectively arranged on both sides of the taping groove 4, and the vertical optical fiber detector 7 is located above the taping groove 4. When the present invention starts the taping packaging production, the staff pre-puts the resonator into the rotary vibrating feeder 2. The rotary vibrating feeder 2 starts to vibrate and vibrates the resonator onto the material track on the inner side wall. The material track is spirally wound around the inner side wall of the rotary vibrating feeder 2 and is connected to the linear vibrating track 3. The resonator is then transported to the picking mechanism along the material track and the linear vibrating track 3. The picking mechanism places the resonator into the taping mechanism and completes operations such as film sealing and tape winding through the film sealing mechanism.

[0018] In this embodiment, the taping mechanism includes a carrier tape roller 8 and a take-up tape roller 9 that are symmetrically arranged on the front and rear sides of the machine table 1. A first stepping motor is arranged on the take-up tape roller 9. A taping tape 10 is connected between the carrier tape roller 8 and the take-up tape roller 9. The taping tape 10 is placed in the taping groove 4 and is slidably matched with the taping groove 4. A number of placement grooves 11 are evenly arranged on the taping tape 10, and a number of through holes 12 are also arranged on both sides of the taping tape 10. Before the present invention starts to work, the staff needs to install the carrier tape roller 8 wound with the taping tape 10 on the transmission shaft of the first stepping motor and lead the taping tape 10 through the taping groove 4 to the take-up tape roller 9. The taping groove 4 plays a role in limiting and guiding the taping tape 10. The resonator is placed into the placement grooves 11 through the picking mechanism.

[0019] In this embodiment, the material taking mechanism includes a negative pressure suction head 13, a progressive conveying device, and a testing device. The progressive conveying device is connected to the linear vibrating track 3. The testing device is arranged at the starting position of the progressive conveying device. The negative pressure suction head 13 is arranged at the end position of the progressive conveying device through a vertical cylinder 14. The progressive conveying device includes a feeding trough 15. Clamping blocks 16 are arranged on the left and right sides of the feeding trough 15. A number of concave work positions 17 are evenly arranged on the clamping blocks 16. A clamping cylinder 18 and a second stepping motor are further arranged below the clamping blocks 16. A defective product collection box 19 is also arranged between the progressive conveying device and the negative pressure suction head 13. The testing device includes a testing pressure plate 20 arranged above the progressive conveying device and a testing probe 21 arranged below the progressive conveying device. The testing probe 21 and the testing pressure plate 20 are both connected to a testing driving cylinder 22. The testing probe 21 and the testing pressure plate 20 are both corresponding to the positions of the concave work positions 17. When the resonator is conveyed by the linear vibrating track 3 to the position of the testing device, the testing driving cylinder 22 is started. The testing pressure plate 20 presses down, and the testing probe 21 jacks up to clamp the resonator, and tests items such as the frequency, resistance, and preset parameters of the resonator. The device records the test results of each resonator. After the test is completed, the clamping cylinder 18 is started to control the clamping blocks 16 on the left and right sides of the feeding trough 15 to tighten inward. The two concave work positions 17 are combined to form a clamping cavity. At this time, the resonator is clamped in the clamping cavity. The second stepping motor is started. After the clamping blocks 16 move forward one step, they are released. The above steps are continuously repeated until the resonator is conveyed to the end position of the feeding trough 15. According to the test records, defective products will be picked up by the clamping blocks 16 and put into the defective product collection box 19, and good products will be adsorbed by the negative pressure suction head 13 for the next step of work. When the negative pressure suction head 13 adsorbs, when the adsorption pressure value reaches the set -50PKa, the vertical cylinder 14 is started. The negative pressure suction head 13 rises, moves above the taping groove 4, aligns with the placing groove 11 and then descends to place the resonator into the placing groove 11. The pressure value rises from -50PKa to 0.3PKa, and the negative pressure suction head 13 is separated from the resonator and reset.

[0020] After the negative pressure suction head 13 places the resonator into the placement groove 11, the tape 10 moves forward to the position where the detection mechanism is located under the drive of the first stepping motor. At this time, the vertical optical fiber detector 7 is activated and detects the upper surface of the resonator to determine whether it is turned over. When it is detected that there is a situation of being turned over, the present invention stops the machine. After manual adjustment, the equipment is restarted. After completing the turnover detection, the first stepping motor continues to rotate, and the tape 10 is further moved forward by one position. At this time, the resonator passes through the positions of the horizontal light source generator 5 and the horizontal light source receiver 6. When there are situations such as standing on its side or floating, the resonator will block the horizontal light source receiver 6 from receiving the light emitted by the horizontal light source generator 5, and this is used as the basis for judgment. If the light source signal is blocked, the equipment stops, and after manual adjustment, it continues to start. In this embodiment, the horizontal light source generator 5 and the horizontal light source receiver 6 are separated from the vertical optical fiber detector 7 by a distance equal to the distance between two adjacent placement grooves 11.

[0021] In this embodiment, the film sealing mechanism includes a film sealing roller 23, a guide shaft group, and a hot pressing knife 24. The film sealing roller 23 is disposed directly above the tape slot 4, and the film is transferred to the tape 10 through the guide shaft group. A third stepping motor is provided on the film sealing roller 23. Two hot pressing knives 24 are symmetrically disposed on both sides of the tape slot 4 through a lifting cylinder 25 and protrude into the tape slot 4. The guide shaft group includes a first guide shaft 26 fixedly disposed on the machine table 1 and closely attached to the tape 10. A second guide shaft 27 is disposed directly above the first guide shaft 26. The second guide shaft 27 and the film sealing roller 23 are disposed on the same horizontal plane. The film is transferred to the tape 10 through the second guide shaft 27 and the first guide shaft 26. The film sealing mechanism further includes a punching roller 28. Punching gear disks 29 adapted to the through holes 12 are disposed on the left and right sides of the punching roller 28. A fourth stepping motor is provided on the punching roller 28. When the resonator is placed in the placement slot 11 and passes the detection of the detection mechanism, the tape is started to be film-sealed. The third stepping motor is started to drive the film sealing roller 23 to rotate. The packaging film is successively covered on the upper surface of the tape 10 under the action of the second guide shaft 27 and the first guide shaft 26 and wraps the resonator. As the tape 10 further moves forward and enters the area where the hot pressing knife 24 is located, the lifting cylinder 25 is started at this time. The hot pressing knife 24 is energized and heated to a certain temperature and descends until it presses on the tape 10. The packaging film is adhered to the tape 10 by hot pressing. After completion, the hot pressing knife 24 moves upward. The tape 10 moves forward to the position where the punching roller 28 is located under the drive of the first stepping motor. The fourth stepping motor is started, and the punching roller 28 rotates. The punching gear disks 29 punch holes in the packaging film along the positions of the through holes 12. After the whole process is completed, the first stepping motor rotates, and the tape take-up roller 9 takes up the tape, continuously repeating the above process until the tape in the tape carrier roller 8 is completely filled. In this embodiment, the rotation frequencies of the first stepping motor, the second stepping motor, the third stepping motor, and the fourth stepping motor are exactly the same.

[0022] While realizing full-automatic loading, packaging, taping and other operations, the present invention detects and tests the whole process, effectively improving the accuracy of the production process, greatly enhancing the production efficiency, and reducing the labor cost.

[0023] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
