Description

Technical Field

[0001] The present invention relates to the technical field of packaging devices, and more specifically, to a piezoelectric ceramic packaging device and a packaging method. Background Art

[0002] As an important functional material, piezoelectric ceramics are widely used in sensors, actuators, acoustic devices and other fields. The accuracy and efficiency of their packaging process directly affect the performance and reliability of the products. In the piezoelectric ceramic packaging process, tape transmission is the core equipment for key processes such as chip loading, wire bonding, packaging testing, tape packaging and cutting, and subsequent processing and storage. Among them, in the chip loading and conveying stage, the tape ensures that the chip maintains a precise position during the conveying process through the cooperation of positioning holes and positioning columns; in the wire bonding and packaging testing stage, the positioning accuracy of the tape directly affects the alignment effect of the chip and the lead and the accuracy of the test.

[0003] However, when the existing piezoelectric ceramic packaging device is used for a long time, the frequent contact and relative movement between the positioning column and the positioning hole of the braid is the main factor causing the wear of the positioning column. As the use time increases, the surface material of the positioning column gradually wears out due to continuous friction, and its dimensional accuracy changes accordingly, which significantly affects the positioning accuracy of the braid conveying. In addition, the positioning column will also suffer fatigue damage during long-term continuous operation. The damage gradually accumulates inside the material, causing the structural strength of the positioning column to decrease, further aggravating the degree of wear. Wear and fatigue damage of the positioning column will eventually lead to offset and misalignment during the conveying process, which in turn causes cumulative deviations.

[0004] Specifically, cumulative deviation refers to the gradual accumulation of deviations between the actual position and theoretical position of the tape conveying due to the combined effects of multiple factors such as positioning column wear and mechanical transmission system errors during the tape conveying process. This not only reduces production efficiency, but may also cause equipment jams, leading to production line stagnation and increased equipment maintenance costs. Summary of the invention

DETAILED DESCRIPTION

[0035] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0036] Embodiment 1: According to Figures 1 to 4 As shown, a piezoelectric ceramic packaging device includes a cabinet 100, and a workbench 200 is installed on the cabinet 100, and a feeding unit 300, a loading unit 400, a packaging tape conveying unit 500 and a controller 600 are arranged on the workbench 200. Among them, a packaging tape 700 is wound on the loading unit 400, and the packaging tape 700 is transmitted by the packaging tape conveying unit 500. A plurality of positioning holes 800 are arranged on the packaging tape 700, and the positioning holes 800 are transmitted and positioned by the feeding unit 300, so that the packaging tape 700 can be accurately transmitted, thereby ensuring the accuracy in the packaging process.

[0037] according to Figure 5As shown, the feeding unit 300 includes a base 310 installed on the packaging tape conveying unit 500, and a servo motor 320 and a first fixed frame 330 are installed on the base 310, a feeding wheel assembly 340 is provided on the output shaft of the servo motor 320, and a switching assembly 350 is provided on the feeding wheel assembly 340 for switching the feeding wheel assembly 340, so as to avoid wear and aging of the feeding wheel assembly 340 due to long-term use, which causes cumulative deviations of the packaging tape 700, resulting in interference between the packaging work and jamming.

[0038] It should be understood that, through the cooperation between the positioning hole 800 and the feeding unit 300, the accuracy of the packaging tape 700 during the transmission process is ensured, and the packaging quality problems caused by position deviation are reduced; and, through the switching component 350, the feeding wheel assembly 340 can be switched to the spare wheel in time before it is worn out, thereby avoiding the cumulative deviation problem caused by the long-term use of a single wheel; among them, by regularly switching the wheels, the wear of each wheel is made more uniform, the service life of the wheel is extended, and the maintenance cost of the equipment is reduced.

[0039] Specifically, according to Figure 7 , Figure 8 and Fig. 9 As shown, the feed wheel assembly 340 includes a spline shaft 341 installed on the output shaft of the servo motor 320, and the spline shaft 341 is slidably connected with a first connecting rod 342 and a second connecting rod 343, and the first connecting rod 342 and the second connecting rod 343 are both provided with a spline groove that matches the spline shaft 341; through the setting of the spline groove, the first connecting rod 342 and the second connecting rod 343 can move on the spline shaft 341, which is convenient for switching the wheel. It should be noted here that the introduction of the switchable feed wheel assembly 340 and the switching between different feed trays through the switching assembly 350 avoids the wear and aging problem caused by the long-term use of a single feed tray. This design effectively reduces the cumulative deviation caused by the wear of the feed tray, and further ensures the accuracy of the packaging process.

[0040] Among them, two groups of first feeding trays 344 are installed on the first connecting rod 342, one group is the first feeding tray to be replaced, and the other group is the first working feeding tray. Two groups of second feeding trays 345 are installed on the second connecting rod 343, one group is the second feeding tray to be replaced, and the other group is the second working feeding tray.

[0041] It should be understood that when the first connecting rod 342 and the second connecting rod 343 move on the spline shaft 341, the first feeding tray 344 and the second feeding tray 345 move synchronously on the spline shaft 341, so as to facilitate the switching operation of the feeding wheel assembly 340, so that the first feeding tray 344 and the second feeding tray 345 on the feeding wheel assembly 340 are respectively exchanged in position. In other words, the first working feeding tray is switched to the first feeding tray to be replaced, and the second working feeding tray is switched to the second feeding tray to be replaced.

[0042] Furthermore, a limiting track is installed on the first connecting rod 342, and a limiting slot is provided on the second connecting rod 343, and the limiting track and the limiting slot are slidably connected; through the setting of the limiting track and the limiting slot, the first connecting rod 342 and the second connecting rod 343 are limitedly engaged, so that the spline shaft 341 remains stable when driving the first connecting rod 342 and the second connecting rod 343 to rotate. Among them, a bracket 370 is also installed on the base 310 for supporting the first connecting rod 342 and the second connecting rod 343.

[0043] Furthermore, according to Figure 7 and Fig. 9 As shown, a first infrared receiver 348 is mounted on the first connecting rod 342, a second infrared receiver 349 is mounted on the second connecting rod 343, a bracket 3410 is further mounted on the base 310, and an infrared transmitter 3411 is mounted on the bracket 3410. The first infrared receiver 348 or the second infrared receiver 349 cooperates with the infrared transmitter 3411 to control the first working feed tray to switch to the first feed tray to be replaced, or to control the first working feed tray to switch to the second feed tray to be replaced.

[0044] Specifically, when it is necessary to switch the feed wheel assembly 340, the operator needs to operate the controller 600 to configure the work so that the first infrared receiver 348, the second infrared receiver 349 and the infrared transmitter 3411 are powered on, so as to facilitate the control of the timing of switching, and by using the first infrared receiver 348, the second infrared receiver 349 and the infrared transmitter 3411 to trigger the switching function, the operation is simple, thereby achieving the effect of non-stop replacement.

[0045] In this embodiment, the operator only needs to perform simple configuration through the controller 600 to complete the switching operation of the feed wheel assembly 340, without stopping the machine for manual replacement. This process not only reduces the downtime caused by equipment maintenance, but also improves the overall operating efficiency of the equipment. In addition, by regularly switching the feed wheel assembly 340, the wear of each feed wheel assembly 340 is more uniform, avoiding equipment failure caused by excessive wear of a single part.

[0046] When the first infrared receiver 348 rotates to the position corresponding to the infrared transmitter 3411, the first infrared receiver 348 and the infrared transmitter 3411 are connected to control the first connecting rod 342 to move, thereby driving the first working feed tray to switch to the first feed tray to be replaced.

[0047] When the second infrared receiver 349 rotates to the position corresponding to the infrared transmitter 3411, the second infrared receiver 349 and the infrared transmitter 3411 are connected to control the second connecting rod 343 to move, thereby driving the second working feed tray to switch to the second feed tray to be replaced.

[0048] according to Figure 7 and Figure 8 As shown, the switching assembly 350 includes a first driving ring 351 installed on the first connecting rod 342, and a second driving ring 352 installed on the second connecting rod 343. The first driving ring 351 and the second driving ring 352 control the movement of the first connecting rod 342 and the second connecting rod 343 to achieve rapid switching of the feeding wheel assembly 340, effectively avoiding inaccurate transmission of the packaging tape 700 caused by wheel position deviation, thereby significantly improving the packaging accuracy.

[0049] It should be noted that according to Figure 7 , Figure 8 and Fig. 9 As shown, a sliding groove 346 is opened on the outer wall of the first connecting rod 342, and the second driving ring 352 is slidably connected to the sliding groove 346. Through the setting of the sliding groove 346, the second driving ring 352 can be slidably connected to the outside of the first connecting rod 342, and the second driving ring 352 is slidingly limited with a first limiting frame 353, and the first driving ring 351 is slidingly limited with a second limiting frame 354.

[0050] In this embodiment, when the first limit frame 353 is driven to move, the second drive ring 352 is controlled to move outside the slide groove 346. When the second limit frame 354 is driven to move, the first drive ring 351 is controlled to move, thereby driving the first connecting rod 342 and the second connecting rod 343 to move respectively, thereby facilitating the control of the first working feed tray to switch to the first feed tray to be replaced, or controlling the first working feed tray to switch to the second feed tray to be replaced, thereby reducing the cumulative deviation caused by mechanical wear or vibration, ensuring the position accuracy of the packaging tape 700 during the transmission process, and avoiding packaging quality problems caused by position deviation.

[0051] Specifically, according to Fig.10 and Fig.11As shown, an electric push rod 3531 is installed on the first fixed frame 330, and the electric push rod 3531 is provided with a telescopic shaft that can perform telescopic movement inside the electric push rod 3531, the telescopic shaft on the electric push rod 3531 is slidably connected to the first limit frame 353, and is slidably connected to the telescopic shaft through the first limit frame 353, so that the telescopic shaft can freely telescope under the control of the electric push rod 3531, and the first limit frame 353 can slide on the telescopic shaft.

[0052] The first limit block 3532 is installed at one end of the telescopic shaft away from the electric push rod 3531, and the movement of the first limit frame 353 is limited by the setting of the limit block. A first spring 3533 is provided on the limit shaft, and one end of the first spring 3533 is fixedly connected to the electric push rod 3531, and the other end of the first spring 3533 is fixedly connected to the first limit frame 353. The elastic connection of the first spring 3533 can control the expansion distance of the first limit frame 353.

[0053] It should be understood that when the electric push rod 3531 controls the telescopic shaft to move, the limit of the first spring 3533 is released, and the first limit block 3532 is controlled to move synchronously. The elastic telescopic force of the first spring 3533 is used to control the first limit frame 353 to unfold, thereby driving the second drive ring 352 to move, so that the second connecting rod 343 moves synchronously, and the second working feed tray is switched to the second feed tray to be replaced.

[0054] When the second working feed tray is switched to the second feed tray to be replaced, the electric push rod 3531 moves continuously, and the moving distance is preferably the distance when the first working feed tray is switched to the first feed tray to be replaced.

[0055] Further, a second fixing frame 3534 is mounted on the base 310, and a connecting shaft 3535 is rotatably connected to the second fixing frame 3534 via a bearing, a first gear 3536 is mounted on the connecting shaft 3535, and a first rack plate 3537 is meshedly connected to the first gear 3536, and the first rack plate 3537 is fixedly connected to the first limit block 3532. In this embodiment, the connecting shaft 3535 and the second fixing frame 3534 are connected via a one-way bearing or a ratchet mechanism, so that the connecting shaft 3535 can only be controlled to rotate in one direction.

[0056] In addition, a slide bar 3541 is installed on the base 310, and a sleeve 3543 is slidably connected to the slide bar 3541, and a second spring 3542 is also provided on the slide bar 3541. A second gear 3538 is also installed on the connecting shaft 3535, and a second rack plate 3539 is meshedly connected to the second gear 3538, and the second rack plate 3539 is fixedly connected to the sleeve 3543.

[0057] It should be noted that when the second working feed tray is switched to the second feed tray to be replaced, the first rack plate 3537 is meshed with the first gear 3536, and through the action of a one-way bearing or a ratchet mechanism, the second gear 3538 idles on the second rack plate 3539 to avoid the sliding sleeve 3543 from getting stuck when the second gear 3538 and the second rack plate 3539 are meshed and connected under the control of the locking assembly 360.

[0058] On the other hand, when the second working feed tray is switched to the second feed tray to be replaced, the first infrared receiver 348 is connected to the infrared transmitter 3411 to drive the electric push rod 3531 to move, controlling the locking assembly 360 to release the limit of the sliding sleeve 3543.

[0059] At this time, since the limit of the sliding sleeve 3543 is released, under the action of the restoring force of the second spring 3542, the second connecting rod 343 is controlled to move quickly, so that the sliding sleeve 3543 is slidably connected to the outside of the sliding rod 3541, thereby switching the second working feed tray to the second feed tray to be replaced.

[0060] When the first feed tray to be replaced needs to be switched to the first working feed tray, and the second feed tray to be replaced needs to be switched to the second working feed tray, the electric push rod 3531 controls the telescopic shaft to reset. When the telescopic shaft retracts, the electric push rod 3531 has been moving continuously in the previous work.

[0061] Therefore, when the telescopic shaft is reset, the first rack plate 3537 and the first gear 3536 are controlled to engage and connect, thereby driving the connecting shaft 3535 to rotate, and the second gear 3538 and the second rack plate 3539 are synchronously controlled to engage and connect, and the first drive ring 351 is preferentially controlled to control the first connecting rod 342 to reset, so that the first feed tray 344 moves synchronously, and then the first limit block 3532 is engaged and connected with the first limit frame 353, and the first limit frame 353 is controlled to move, so that the first limit frame 353 controls the second drive ring 352 to move, and the second connecting rod 343 is controlled to move through the second drive ring 352, so that the second feed tray 345 moves synchronously, thereby performing a reset movement.

[0062] according to Figure 6 and Fig.10 As shown, the locking assembly 360 includes a receiving frame 361 mounted on the feeding unit 400, and a movable rod 362 is slidably connected to the receiving frame 361, and a top plate 363 is installed at one end of the movable rod 362 close to the feeding wheel assembly 340, and a third spring 364 is provided on the movable rod 362, and one end of the third spring 364 is mounted on the receiving frame 361, and the other end of the third spring 364 is mounted on the top plate 363. It should be noted here that according to Figure 8 and Fig. 9 As shown, a protrusion 347 is installed at one end of the second connecting rod 343 away from the servo motor 320 .

[0063] Specifically, a first tilting block 365 is installed at one end of the movable rod 362 away from the top plate 363, and a second tilting block 366 is provided on the first tilting block 365, a first guide rod 367 is installed on the second tilting block 366, and a connecting plate 368 is slidably connected to the first guide rod 367, and the connecting plate 368 is installed on the packaging belt conveying unit 500; a fourth spring 369 is provided on the first guide rod 367, and one end of the fourth spring 369 is fixedly connected to the second tilting block 366, and the other end of the fourth spring 369 is fixedly connected to the connecting plate 368; a connecting rod 3610 is installed at one end of the first guide rod 367 away from the second tilting block 366, and a clamping block is installed at one end of the connecting rod 3610 away from the first guide rod 367, and a clamping groove 3544 is provided on the sliding sleeve 3543, and the clamping block is clamped and connected with the clamping groove 3544.

[0064] It should be understood that when the protrusion 347 contacts the top plate 363, the movable rod 362 is controlled to move, the third spring 364 is compressed, and the first inclined block 365 is controlled to squeeze the second inclined block 366, so that the first guide rod 367 moves, thereby driving the connecting rod 3610 to move synchronously, controlling the block to move from the slot 3544, and releasing the limit of the sleeve 3543.

[0065] Embodiment 2: According to Figures 1 to 11 As shown, a piezoelectric ceramic packaging method, using a piezoelectric ceramic packaging device as disclosed in the first embodiment, comprises the following steps:

[0066] S1, start the servo motor 320 to put the feeding wheel assembly 340 into a standby state;

[0067] S2, start the electric push rod 3531 through the controller 600 to push the telescopic shaft out, driving the first limit frame 353 to move along the slide groove 346;

[0068] S3, when the first infrared receiver 348 is aligned with the infrared transmitter 3411, the second driving ring 352 is controlled to move so that the second working feeding tray on the second connecting rod 343 is switched to the second feeding tray to be replaced;

[0069] At the same time, the first driving ring 351 is controlled to move by the second limiting frame 354, so that the first working feeding tray on the first connecting rod 342 is switched to the first feeding tray to be replaced;

[0070] S4. The servo motor 320 of the feeding unit 300 drives the feeding wheel assembly 340 to accurately transfer the piezoelectric ceramic chip on the packaging tape 700 to the packaging position.

[0071] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
