Description

Technical Field

[0001] The utility model relates to the technical field of ceramic chip manufacturing, in particular to a surface changing table device. Background Art

[0002] In the end-capping process of MLCC multilayer ceramic chips, after the external electrode slurry is applied to the exposed part of the inner electrode on one side of the chip and sintered at high temperature to form the external electrode, the chip needs to be re-faced to make the external electrode on the other side of the chip. During the re-face operation, the chip end-capping carrier is generally placed on the re-face table, and the carrier is adsorbed and fixed by the re-face table. Whether the re-face table firmly fixes the carrier will affect the re-face process and thus affect the chip quality. If the re-face table does not firmly fix the carrier, the force generated when the glue is peeled off during the re-face process will cause the carrier to separate from the re-face table. During the separation process, the chip end will have quality problems such as collision or scratches of varying degrees. At present, after the carrier is placed on the re-face table, the next step of peeling glue is generally carried out immediately. It is impossible to judge whether the carrier is firmly adsorbed on the re-face table. In this case, the carrier may be separated from the re-face table during the peeling glue process, which may affect the chip quality. Utility Model Content

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] See also Figure 1 The embodiment of the utility model provides a facing table device, including a facing table 1, a vacuum chamber 2, a vacuum pumping mechanism and a vacuum detection gauge 3. The interior of the vacuum chamber 2 is hollow, and the top of the vacuum chamber 2 has an opening connected to the interior of the vacuum chamber 2; the facing table 1 covers the opening of the vacuum chamber 2, and a plurality of adsorption holes 11 are provided on the facing table 1, and each adsorption hole 11 is connected to the interior of the vacuum chamber 2; the vacuum pumping mechanism is connected to the vacuum chamber 2 to form a vacuum inside the vacuum chamber 2; the vacuum detection gauge 3 is connected to the vacuum chamber 2, and the vacuum detection gauge 3 is used to detect the vacuum pressure value in the vacuum chamber 2.

[0028] The vacuum chamber 2 is evacuated by the vacuum pumping mechanism, and the vacuum pressure value in the vacuum chamber 2 is detected by the vacuum detection meter 3. The vacuum pressure value detected by the vacuum detection meter 3 can be used to determine whether the vacuum degree in the vacuum chamber 2 meets the set requirements, and whether the vacuum adsorption force provided by the reversing table 1 meets the set requirements, so that before the glue peeling operation is performed, the reversing table 1 can be tested to determine whether the carrier on the reversing table 1 is firmly adsorbed. When the vacuum pressure value detected by the vacuum detection meter 3 reaches the set value, it indicates that the reversing table 1 firmly adsorbs the carrier. When the vacuum pressure value detected by the vacuum detection meter 3 does not reach the set value, it indicates that the vacuum adsorption force of the reversing table 1 on the carrier does not meet the set requirements. At this time, the vacuum pumping force of the vacuum pumping mechanism can be adjusted to enhance the vacuum degree in the vacuum chamber 2 and the vacuum adsorption force of the reversing table 1, so that the reversing table 1 firmly adsorbs the carrier, thereby avoiding the separation of the carrier from the reversing table 1 during the glue peeling operation, which may cause quality problems such as collision or scratches on the chip end.

[0029] See also Figure 1 The resurfacing table 1 is in the shape of a flat plate. The resurfacing table 1 is used to place the carrier used in the chip termination process. A plurality of adsorption holes 11 are evenly distributed on the resurfacing table 1 to provide a balanced adsorption force to the carrier to prevent one side of the carrier from warping. The central axis of the adsorption hole 11 extends along the thickness direction of the resurfacing table 1 to communicate with the inside of the vacuum chamber 2 on the lower side of the resurfacing table 1.

[0030] See also Figure 1 In some embodiments, a storage bin 6 is provided at the lower side of the vacuum bin 2, and a vacuum pumping mechanism is provided in the storage bin 6. The vacuum bin 2 and the storage bin 6 are both rectangular box structures. The vacuum pumping mechanism is a prior art, and the vacuum pumping mechanism may include facilities such as a vacuum pump and a gas storage tank, and the vacuum bin 2 is vacuumed by the vacuum pump. The face changing table device also includes a workbench 7, and the vacuum bin 2, the vacuum pumping mechanism, and the vacuum detection meter 3 are all installed on the workbench 7. The workbench 7 serves as a bearing platform for the face changing table device, and the vacuum detection meter 3, the vacuum pumping mechanism, etc. are all installed on the workbench 7, which facilitates the connection between the vacuum detection meter 3 and the vacuum bin 2. When the vacuum pumping mechanism is provided in the storage bin 6, the storage bin 6 is provided on the workbench 7, and the vacuum bin 2 can be provided on the upper side of the storage bin 6, which reduces the occupied space and facilitates the layout. The vacuum detection meter 3 can be fixed on the workbench 7 by a bracket 8, and the bracket 8 is a right-angle type to reduce the installation space.

[0031] See also Figure 2 and Figure 3As shown, a digital display 31 is provided on the vacuum detection gauge 3. The detected vacuum pressure value can be intuitively displayed by the digital display 31, so that it is convenient to judge whether the vacuum degree of the vacuum chamber 2 meets the set requirements according to the displayed vacuum pressure value, thereby obtaining whether the adsorption of the carrier by the face-changing table 1 is firm. The display value of the digital display 31 is a negative value. The vacuum detection gauge 3 is a vacuum pressure gauge with a detection range of 0 to -101 kPa. A vacuum tube socket 32 ​​is provided on the vacuum detection gauge 3, and the vacuum detection gauge 3 is connected to the vacuum chamber 2 through a vacuum tube. The vacuum tube socket 32 ​​is arranged on the back of the digital display 31, which is convenient for the connection between the vacuum detection gauge 3 and the vacuum chamber 2. A wire socket 34 is also provided on the back of the digital display 31, which is convenient for connecting a power source, etc.

[0032] See also Figure 1 In some embodiments, the resurfacing table device further includes a controller and a first prompt light 4, and the vacuum detection meter 3 and the first prompt light 4 are electrically connected to the controller respectively. When the vacuum pressure value detected by the vacuum detection meter 3 reaches the set value, the vacuum detection meter 3 outputs a feedback signal to the controller. The controller controls the first prompt light 4 to light up, thereby intuitively prompting the operator to proceed with the next step of the glue peeling operation without having to observe the displayed value on the vacuum detection meter 3 all the time. The first prompt light 4 may have a built-in buzzer, which emits a buzzer to remind the staff when the first prompt light 4 lights up.

[0033] In some embodiments, the face changing table device further includes a timer and a second prompt light 5, and the timer and the second prompt light 5 are electrically connected to the controller respectively. When the vacuum pressure value detected by the vacuum detection meter 3 does not reach the set value, the vacuum detection meter 3 outputs a signal to the controller. The controller controls the timer to count. When the timer timing reaches the set duration (for example, the set duration can be 3 seconds), the timer feeds back a timing signal to the controller. The controller controls the second prompt light 5 to light up. The second prompt light 5 reminds the operator that there may be a problem that the face changing table 1 is not firmly adsorbed to the carrier, and it is necessary to adjust the adsorption strength of the face changing table 1 so as to adjust the vacuum strength in time, improve the adsorption force of the face changing table 1, and make the face changing table 1 firmly adsorb the carrier. By setting the timer, it is possible to avoid the vacuum pressure value detected by the vacuum detection meter 3 not meeting the standard instantaneously and causing misoperation. The light color of the first prompt light 4 is different from the light color of the second prompt light 5. For example, the first prompt light 4 lights up in green, and the second prompt light 5 lights up in red.

[0034] In order to facilitate the presetting of the set pressure value of the vacuum detection gauge 3, a button 33 is provided on the lower side of the digital display 31. The set pressure value can be pre-set through the button 33, so as to compare the real-time detection value of the vacuum detection gauge 3 with the set pressure value, and to control the first prompt light 4 to light up when the detection value reaches the set pressure value. When the detection value does not reach the set pressure value, the timer is controlled to count. The button 33 includes a setting button, an up button, and a down button.

[0035] In some embodiments, the resurfacing device further comprises an alarm, which is electrically connected to the controller. When the second prompt light 5 is on, the controller controls the alarm to sound an alarm, so as to visually prompt the operator to adjust the vacuum strength of the vacuum chamber 2 of the resurfacing device. The alarm may be built into the second prompt light 5. The alarm is a buzzer.

[0036] The working process of the utility model is:

[0037] After placing the carrier on the refacing table 1, start the vacuum pumping mechanism and the vacuum detection meter 3. The vacuum chamber 2 is vacuumed by the vacuum pumping mechanism, so that the refacing table 1 adsorbs and fixes the carrier. The vacuum pressure value in the vacuum chamber 2 is detected by the vacuum detection meter 3. When the vacuum pressure value detected by the vacuum detection meter 3 reaches the set pressure value, the first prompt light 4 can be controlled by the controller to light up, indicating that the refacing table 1 adsorbs the carrier firmly and the next step of the glue peeling operation can be carried out. When the vacuum pressure value detected by the vacuum detection meter 3 does not reach the set pressure value, the controller controls the timer to count, and when the timer counts for the set time, the controller controls the second prompt light 5 to light up. At this time, there may be a problem that the refacing table 1 adsorbs the carrier loosely. The operator needs to adjust the vacuum pumping operation of the vacuum pumping mechanism, increase the vacuum pumping strength, and increase the vacuum degree of the vacuum chamber 2, thereby increasing the adsorption force of the refacing table 1 on the carrier, so that the refacing table 1 adsorbs the carrier firmly.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
