Description

Technical Field

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

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

[0003] However, during the long-term use of existing piezoelectric ceramic encapsulation devices, the frequent contact and relative movement between the positioning posts and the tape positioning holes are the main factors leading to the wear of the positioning posts. As the use time prolongs, the surface material of the positioning posts gradually wears due to continuous friction, and its dimensional accuracy changes accordingly, thereby significantly affecting the positioning accuracy of the tape conveyance. In addition, the positioning posts will also suffer fatigue damage during long-term continuous operation, and the damage gradually accumulates inside the material, resulting in a decrease in the structural strength of the positioning posts, further exacerbating the wear degree. The wear and fatigue damage of the positioning posts will ultimately lead to offset and misalignment phenomena during the conveyance process, thereby causing cumulative deviation.

[0004] Specifically, cumulative deviation refers to the deviation between the actual position and the theoretical position of the tape conveyance gradually accumulating during the tape conveyance process due to the combined action of various factors such as the wear of the positioning posts and the errors of the mechanical transmission system. This not only reduces production efficiency but may also cause the equipment to jam, leading to the stagnation of the production line and increasing the equipment maintenance cost.

Detailed implementation mode

[0035] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, the functions and arrangements of the elements discussed can be changed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described for some examples can also be combined in other examples.

[0036] Example 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. 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 through the packaging tape conveying unit 500. A plurality of positioning holes 800 are provided 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, ensuring the accuracy during the packaging process.

[0037] According to Figure 5As shown in the figure, the feeding unit 300 includes a base 310 installed on the encapsulation tape conveying unit 500. A servo motor 320 and a first fixing bracket 330 are installed on the base 310. A feeding wheel disc assembly 340 is provided on the output shaft of the servo motor 320, and a switching assembly 350 is provided on the feeding wheel disc assembly 340 for switching the feeding wheel disc assembly 340, so as to avoid wear and aging of the feeding wheel disc assembly 340 during long-term use, resulting in cumulative deviation of the encapsulation tape 700 and causing jamming due to mutual interference in the encapsulation work.

[0038] It should be understood that through the cooperation of the positioning holes 800 and the feeding unit 300, the accuracy of the encapsulation tape 700 during transmission is ensured, and the encapsulation quality problems caused by position deviation are reduced; moreover, through the switching assembly 350, it is possible to switch to the spare wheel disc in time before the feeding wheel disc assembly 340 wears out and ages, avoiding the problem of cumulative deviation caused by the long-term use of a single wheel disc; among them, by regularly switching the wheel discs, the wear of each wheel disc is made more uniform, the service life of the wheel discs is extended, and the maintenance cost of the equipment is reduced.

[0039] Specifically, according to Figure 7 、 Figure 8 and Figure 9 As shown in the figure, the feeding wheel disc assembly 340 includes a spline shaft 341 installed on the output shaft of the servo motor 320. A first connecting rod 342 and a second connecting rod 343 are slidably connected to the spline shaft 341. Spline grooves adapted to the spline shaft 341 are provided on the first connecting rod 342 and the second connecting rod 343; through the setting of the spline grooves, the first connecting rod 342 and the second connecting rod 343 can move on the spline shaft 341, facilitating the switching operation of the wheel discs. It should be noted here that the introduction of the switchable feeding wheel disc assembly 340, through the switching assembly 350 to switch between different feeding discs, avoids the problem of wear and aging caused by the long-term use of a single feeding disc. This design effectively reduces the cumulative deviation caused by the wear of the feeding disc and further ensures the accuracy of the encapsulation process.

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

[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 disk 344 and the second feeding disk 345 synchronously move on the spline shaft 341, thereby facilitating the switching operation of the feeding wheel disk assembly 340, so that the first feeding disk 344 and the second feeding disk 345 on the feeding wheel disk assembly 340 are respectively exchanged in position. That is to say, the first working feeding disk is switched to the first feeding disk to be replaced, and the second working feeding disk is switched to the second feeding disk to be replaced.

[0042] Further, a limiting track is installed on the first connecting rod 342, and a limiting groove is formed on the second connecting rod 343. The limiting track and the limiting groove are slidably connected; through the arrangement of the limiting track and the limiting groove, the first connecting rod 342 and the second connecting rod 343 are limited and engaged with each other, so that when the spline shaft 341 drives the first connecting rod 342 and the second connecting rod 343 to rotate, stability is maintained. Among them, a bracket 370 is further installed on the base 310 for supporting the first connecting rod 342 and the second connecting rod 343.

[0043] Even further, according to Figure 7 and Figure 9 As shown, a first infrared receiver 348 is installed on the first connecting rod 342, a second infrared receiver 349 is installed on the second connecting rod 343, a bracket 3410 is further installed on the base 310, and an infrared transmitter 3411 is installed on the bracket 3410. Through the cooperation of the first infrared receiver 348 or the second infrared receiver 349 and the infrared transmitter 3411, the first working feeding disk is controlled to be switched to the first feeding disk to be replaced, or the first working feeding disk is controlled to be switched to the second feeding disk to be replaced.

[0044] Specifically, when a switching operation needs to be performed on the feeding wheel disk assembly 340, the operator needs to operate the controller 600 to perform a work configuration, so that the first infrared receiver 348, the second infrared receiver 349, and the infrared transmitter 3411 are powered on, thereby facilitating the control of the switching timing, and the switching function is triggered by using the power-on of the first infrared receiver 348, the second infrared receiver 349, and the infrared transmitter 3411 to work. The operation is simple, and the effect of non-stop replacement is thus completed.

[0045] In this embodiment, the operator only needs to perform a simple configuration through the controller 600 to complete the switching operation of the feeding wheel disk 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 feeding wheel disk assembly 340, the wear of each feeding wheel disk assembly 340 is made more uniform, avoiding equipment failures caused by single excessive wear.

[0046] When the first infrared receiver 348 rotates to the position corresponding to the infrared emitter 3411, the first infrared receiver 348 and the infrared emitter 3411 are turned on, controlling the movement of the first connecting rod 342, thereby driving the first working feeding tray to switch to the first feeding tray to be replaced.

[0047] When the second infrared receiver 349 rotates to the position corresponding to the infrared emitter 3411, the second infrared receiver 349 and the infrared emitter 3411 are turned on, controlling the movement of the second connecting rod 343, thereby driving the second working feeding tray to switch to the second feeding 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 connecting rod 342 and the second connecting rod 343 are controlled to move through the first driving ring 351 and the second driving ring 352, realizing the rapid switching of the feeding wheel assembly 340, effectively avoiding the inaccurate transmission of the packaging tape 700 caused by the position deviation of the wheel, thereby significantly improving the packaging accuracy.

[0049] It should be noted that, as shown in Figure 7 , Figure 8 and Figure 9 a chute 346 is provided on the outer wall of the first connecting rod 342, and the second driving ring 352 is slidably connected to the chute 346. Through the setting of the chute 346, the second driving ring 352 can be slidably connected outside the first connecting rod 342. A first limiting frame 353 is slidably limited on the second driving ring 352, and a second limiting frame 354 is slidably limited on the first driving ring 351.

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

[0051] Specifically, according to Figure 10 and Figure 11As shown, an electric push rod 3531 is installed on the first fixing frame 330, and a telescopic shaft capable of performing telescopic movement inside the electric push rod 3531 is provided on the electric push rod 3531. The telescopic shaft on the electric push rod 3531 is slidably connected to the first limiting frame 353. By slidingly connecting the first limiting frame 353 to the telescopic shaft, the telescopic shaft can perform free telescopic movement under the control of the electric push rod 3531, and the first limiting frame 353 can slide on the telescopic shaft.

[0052] Wherein, a first limiting block 3532 is further installed at one end of the telescopic shaft away from the electric push rod 3531, and the movement of the first limiting frame 353 is limited by the setting of the limiting block. A first spring 3533 is provided on the limiting 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 limiting frame 353. Through the elastic connection of the first spring 3533, the unfolding distance of the first limiting frame 353 can be controlled.

[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 limiting block 3532 is controlled to move synchronously. The first limiting frame 353 is driven to unfold through the elastic telescopic force of the first spring 3533, so as to drive the second driving ring 352 to move, and the second connecting rod 343 moves synchronously, so that the second working feeding tray is switched to the second feeding tray to be replaced.

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

[0055] Furthermore, a second fixing frame 3534 is installed on the base 310, and a connecting shaft 3535 is rotatably connected to the second fixing frame 3534 through a bearing. A first gear 3536 is installed on the connecting shaft 3535, and a first rack plate 3537 is meshed with the first gear 3536. The first rack plate 3537 is fixedly connected to the first limiting block 3532. In this embodiment, the connecting shaft 3535 is connected to the second fixing frame 3534 through a one-way bearing or a ratchet mechanism, so as to control the connecting shaft 3535 to rotate only in one direction.

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

[0057] It should be added that when the second working feeding tray is switched to the second feeding tray to be replaced, the first rack plate 3537 is meshed and connected with the first gear 3536. Under the action of a one-way bearing or a ratchet mechanism, the second gear 3538 idles on the second rack plate 3539 to avoid jamming 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 feeding tray is switched to the second feeding tray to be replaced, the first infrared receiver 348 is conducted with the infrared transmitter 3411 to drive the electric push rod 3531 to displace, and the locking assembly 360 is controlled to release the limit on the sliding sleeve 3543.

[0059] At this time, since the limit on the sliding sleeve 3543 is released, under 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 outside the sliding rod 3541, thereby switching the second working feeding tray to the second feeding tray to be replaced.

[0060] When it is necessary to switch the first feeding tray to be replaced to the first working feeding tray and the second feeding tray to be replaced to the second working feeding tray, the electric push rod 3531 controls the telescopic shaft to reset. When the telescopic shaft retracts, since the electric push rod 3531 has moved 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 be meshed and connected, thereby driving the connecting shaft 3535 to rotate, synchronously controlling the second gear 3538 and the second rack plate 3539 to be meshed and connected, preferentially controlling the first driving ring 351 to control the first connecting rod 342 to reset, so that the first feeding tray 344 moves synchronously, and then the first limiting block 3532 is engaged with the first limiting frame 353 to control the first limiting frame 353 to move, so that the first limiting frame 353 controls the second driving ring 352 to move, and the second driving ring 352 controls the second connecting rod 343 to move, so that the second feeding tray 345 moves synchronously, thereby performing a reset movement.

[0062] According to Figure 6 and Figure 10 As shown, the locking assembly 360 includes a receiving frame 361 mounted on the loading unit 400, and a movable rod 362 is slidably connected to the receiving frame 361. A top plate 363 is mounted at one end of the movable rod 362 close to the feeding wheel disc assembly 340. 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 toFigure 8 and Figure 9 As shown in Figure 9 , a convex block 347 is installed at one end of the second connecting rod 343 away from the servo motor 320.

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

[0064] It should be understood that when the convex block 347 contacts the top plate 363, the movable rod 362 is controlled to move, the third spring 364 is compressed, 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, and controlling the clamping block to move out of the clamping groove 3544 to release the limit of the sliding sleeve 3543.
