[0002] The weight ejector mechanism is an important component of the heating plate system in semiconductor equipment. Figure 1A As shown, the heating plate system 100 is a loading and unloading space for the weight ejector pins. The heating plate system 100 is located in the reaction chamber 130 and may include a plurality of heating plates 110, wherein a plurality of ejector pin holes 111 are provided in the heating plates 110 for inserting the weight ejector pins 120. Through the cooperation of the plurality of weight ejector pins 120, the wafer can be lifted and lowered on the heating plate 110, and the wafer can be transferred.

[0003] like Figure 1B As shown, the structure of the weight ejector pin 120 may include a weight 121, an ejector pin 122 (pin) and a latch 123, wherein the ejector pin 122 may be connected to the weight 121 via the latch 123. In the weight ejector pin 120, the ejector pin 122 may contact the support plate surface at the bottom of the heating plate system 100 via the weight 121, thereby improving the stability of the ejector pin during the lifting and conveying process.

[0004] In the existing operating space of the machine, it is difficult to install and remove the heavy hammer ejector pin 120. Specifically, when installing the ejector pin 122, it needs to be pre-installed on the heating plate 110 in advance, and when removing it, the heating plate 110 needs to be removed first. The above process requires two people to cooperate throughout, which is not only troublesome to operate, but also increases the operation time and risk for some maintenance conditions that do not require the removal and replacement of the heating plate.

[0005] In order to solve the above-mentioned problems existing in the prior art, there is an urgent need in the art for a loading and unloading technology of a heavy hammer ejector pin, which can be used to quickly install and disassemble the heavy hammer ejector pin without removing the heating plate, and can also avoid the ejector pin from falling out due to moving the heating plate when installing the ejector pin without tooling, as well as the problem of the pin being left out when blindly removing the heavy hammer ejector pin at the bottom of the heating plate.

[0063] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation.

In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0066] It is understood that although the terms "first", "second", "third", etc. may be used herein to describe various components, regions, layers and / or parts, these components, regions, layers and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers and / or parts. Therefore, the first component, region, layer and / or part discussed below may be referred to as a second component, region, layer and / or part without departing from some embodiments of the present invention.

[0067] As mentioned above, it is difficult to install and remove the heavy hammer ejector pin 120 in the existing operating space of the machine. Specifically, when installing the ejector pin 122, it needs to be pre-installed on the heating plate 110 in advance, and when removing it, the heating plate 110 needs to be removed first. The above process requires two people to cooperate throughout, which is not only troublesome to operate, but also increases the operation time and risk for some maintenance conditions that do not require the removal and replacement of the heating plate.

[0068] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a loading and unloading tool for a weight hammer ejector, a method for installing a weight hammer ejector, and a method for disassembling a weight hammer ejector, which can quickly install and disassemble the weight hammer ejector without removing the heating plate, and can also avoid the ejector being dislodged due to moving the heating plate when installing the ejector without a tool, and the problem of the pin being left out when blindly disassembling the weight hammer ejector at the bottom of the heating plate, which not only saves manpower but also reduces maintenance time.

[0069] In some non-limiting embodiments, the loading and unloading tooling of the above-mentioned weight ejector pin provided in the first aspect of the present invention can be used to implement the installation method of the above-mentioned weight ejector pin provided in the second aspect of the present invention, and the disassembly method of the above-mentioned weight ejector pin provided in the third aspect of the present invention.

[0070] The following will describe the working principle of the above-mentioned loading and unloading tooling of the weight ejector in conjunction with some embodiments of the installation method and disassembly method of the weight ejector. Those skilled in the art will understand that these embodiments of the installation method and disassembly method of the weight ejector are only some non-limiting implementation methods provided by the present invention, and are intended to clearly demonstrate the main concept of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit all working modes or all functions of the loading and unloading tooling of the weight ejector. Similarly, the loading and unloading tooling of the weight ejector is also only a non-limiting implementation method provided by the present invention, and does not constitute a limitation on the implementation subject of each step in the installation method and disassembly method of the weight ejector.

[0071] Please see Figure 2 , Figure 2 A schematic structural diagram of a loading and unloading tool for a heavy hammer ejector provided according to some embodiments of the present invention is shown.

[0072] like Figure 2 As shown, in some embodiments of the present invention, the loading and unloading tool 200 of the weight ejector pin may include a tool body 210, a first stud 220, and a second stud 230. The tool body 210 may include a groove portion 211 inside for accommodating the weight 121 in the weight ejector pin 120, and a first channel 241 and a second channel 242 intersecting each other may be provided below the groove portion 211.

[0073] Furthermore, a bottom limit surface 243 is provided at the bottom of the intersection 240, which serves as a positioning point for the target installation or removal position of the ejector pin 122 during the installation of the weight ejector pin 120. Specifically, during the installation of the weight ejector pin 120, when the ejector pin 122 is inserted into the center of the weight 121 fixed in the groove portion 211, and the bottom of the ejector pin 122 reaches the bottom limit surface 243, it can be determined that the ejector pin 122 has completely reached the target installation position, and the next step of fixing the latch 123 can be performed.

[0074] Continue as Figure 2 As shown, the first stud 220 in the heavy hammer ejector assembly and disassembly tool 200 can be used to insert into the first channel 241 when the heavy hammer 121 is located in the groove portion 211 and the ejector 122 passes through the heavy hammer 121 and reaches the bottom limit surface 243, so as to push the latch 123 into the latch hole of the ejector 122, thereby completing the assembly of the ejector 122 and the heavy hammer 121. In other words, the assembly of the ejector 122 and the heavy hammer 121 can be completed through the cooperation of the first stud 220 and the first channel 241.

[0075] The second stud 230 in the heavy hammer ejector assembly and disassembly tool 200 can be used to insert into the second channel 242 when the heavy hammer ejector 121 at the bottom of the heavy hammer ejector 120 is located in the groove 211 and the ejector 122 reaches the bottom limit surface 243, so as to push the latch 123 away from the latch hole, thereby completing the disassembly of the heavy hammer ejector 120. In other words, the assembly relationship between the ejector 122 and the heavy hammer 121 can be released through the cooperation of the second stud 230 and the second channel 242.

[0076] Specifically, in some preferred embodiments, in the tool body 210, the tops of the first channel 241 and the second channel 242 below the groove portion 211 can cross each other, that is, the angle between the two channels can be 90°, which is a relatively simple internal channel structure design. Alternatively, in some other embodiments, the angle between the first channel 241 and the second channel 242 can also be other angles, as long as it can be ensured that the first stud 220 inserted from the first channel 241 can push the latch 123 to the latch hole in the ejector pin 122 of the bottom limit surface 243 reaching the target installation position, and the second stud 230 inserted from the second channel 242 can push the latch 123 out of the latch hole in the ejector pin 122 of the bottom limit surface 243 reaching the target installation position.

[0077] For further information, see Figure 3A , Figure 3A A cross-sectional view of a first channel in a tool body provided according to some embodiments of the present invention is shown.

[0078] like Figure 3A As shown, in some embodiments, a first pin stop surface 310 may be provided on the outer side of the first channel 241 located at the intersection 240. Before the ejector pin 122 and the weight 121 are assembled, the latch pin 123 may be temporarily stored in the first channel 241, thereby facilitating further shortening the assembly time of pushing the latch pin 123 into the latch hole of the ejector pin 122. Preferably, in this embodiment, the top of the latch pin 123 temporarily stored in the first channel 241 does not exceed the first pin stop surface 310, that is, the top of the latch pin 123 may at most be flush with the first pin stop surface 310, thereby preventing the subsequent insertion channel of the ejector pin 122 from being blocked, preventing the ejector pin 122 from being completely inserted into the bottom stop surface 243 of the intersection 240, that is, preventing the ejector pin 122 from being placed in the target installation position.

[0079] Further, continuing with FIG. 3A , in some preferred embodiments, the top of the first channel 241 may extend beyond the intersection 240 by a first preset length L1, wherein the first preset length L1 may be smaller than the length of the latch 123, so that the latch 123 may be fully mated with the ejector pin 122 during assembly, and the latch 123 will not be pushed in too deeply, causing the latch 123 to miss the optimal assembly position with the ejector pin 122 and result in a non-mated or incompletely mated relationship.

[0080] Next, see Figure 3B , Figure 3B A cross-sectional view of a second channel in a tool body provided according to some embodiments of the present invention is shown.

[0081] like Figure 3BAs shown, in some embodiments, the top of the second channel 242 can extend beyond the intersection 240 by a second preset length L2, wherein the second preset length L2 can be greater than or equal to the length of the latch 123, and is used to temporarily store and fully accommodate the latch 123 that has been pushed out of the latch hole of the ejector pin 122 when the weight ejector pin 120 is disassembled, thereby preventing the latch 123 from falling or being lost during the disassembly process.

[0082] Further, continuing with FIG. 3B , in some preferred embodiments, a second pin limiting surface 320 may be provided on the inner side of the intersection 240 in the second channel 242, wherein the distance between the second pin limiting surface 320 and the intersection 240 may be greater than or equal to the length of the latch 123, so that after the top of the latch 123 reaches the second pin limiting surface 320, it can ensure that it is completely released from the ejector pin 122.

[0083] Alternatively, if Figure 3B As shown, in some embodiments, the second pin limiting surface 320 may be the top of the second channel 242. In some other embodiments, the second pin limiting surface 320 may also be disposed between the inner side of the intersection 240 and the top of the second channel 242. As long as the distance between the second pin limiting surface 320 and the intersection 240 is greater than or equal to the length of the plug 123, it can be ensured that the plug 123 contacting the second pin limiting surface 320 has been completely removed from the ejector pin 122.

[0084] Furthermore, in some preferred embodiments, the inner wall of the pin hole of the ejector pin 122 may also be provided with an internal thread, and correspondingly, the outer wall of the pin 123 may also be provided with an external thread of a corresponding size, so that the pin 123 and the ejector pin 122 can be threadedly connected to form a detachable fixed connection relationship. Due to the space limitation of the heating plate 110, there is a certain blind adjustment component in the installation and removal process of the weight ejector pin 120. Therefore, the insertion progress of the pin 123 can be determined by the number of turns of the threaded connection between the pin 123 and the ejector pin 122, that is, the screwing degree of the first stud 220 and the second stud 230, so as to avoid the pin 123 being pushed in too shallowly, resulting in an incomplete matching relationship between the pin 123 and the ejector pin 122, and the pin 123 being pushed in too deeply, resulting in the pin 123 missing the matching relationship with the ejector pin 122.

[0085] Optionally, in some embodiments, the end faces of the first stud 220 and the second stud 230 may be provided with a first snap-fit ​​structure, and correspondingly, the end face of the latch 123 may also be provided with a second snap-fit ​​structure matching therewith, so that the end faces of the first stud 220 and the second stud 230 may be respectively snap-fitted with the end faces of the latch 123, thereby facilitating the operator to directly push and / or rotate the first stud 220 or the second stud 230 from the outside to drive the movement and / or rotation of the latch 123 located inside the tooling body 210, thereby enabling the latch 123 to be pushed in or out and / or screwed in or out of the latch hole of the ejector pin 122, thereby achieving blind installation and removal of the latch 123 in the heavy hammer ejector pin 120.

[0086] So far, the main structure of the loading and unloading tool 200 for the weight hammer ejector provided by the first aspect of the present invention has been introduced. Next, the loading and unloading tool 200 for the weight hammer ejector will be further described through the use of the loading and unloading tool 200 for the weight hammer ejector in two working conditions, namely, installation and disassembly.

[0087] Please see Figure 4 , Figure 4 The flowchart of a method for installing a heavy hammer ejector according to some embodiments of the present invention is shown. Figure 5 Common understanding, Figure 5 A schematic diagram of the process of installing a weight ejector pin provided according to a specific embodiment of the present invention is shown.

[0088] like Figure 4 As shown, in some embodiments of the present invention, the installation method of the weight ejector pin may include the following steps. First, step S410 may be performed: placing the loading and unloading tool of the weight ejector pin under the ejector pin hole of the heating plate.

[0089] Specifically, if Figure 5 As shown, step S510 may be performed first to remove the second stud 230 used for disassembly from the second channel 242 to avoid interference with the subsequent installation process. Afterwards, in step S520, the latch 123 may be pre-stored in the first channel 241 to further shorten the assembly time of pushing the latch 123 into the latch hole of the ejector pin 122. Preferably, the top of the latch 123 temporarily stored in the first channel 241 may be kept flush with the first pin limit surface 310, that is, not exceeding the first pin limit surface 310, thereby preventing the subsequent ejector pin 122 from being fully inserted into the bottom limit surface 243 that reaches the target installation position. Optionally, step S520 may also be performed in the subsequent process of pushing the first stud 220 into the latch 123 for installation.

[0090] After completing the above preparation work for the tool body 210 , the tool body 210 can be placed below the ejector hole 111 in the heating plate 110 , and step S530 is performed: installing the ceramic weight 121 in the groove portion 211 of the tool body 210 .

[0091] Then, please continue to return to Figure 4 The installation method of the weight ejector pin may further include step S420: inserting the ejector pin into the ejector pin hole from above, and passing through the weight ejector pin to reach the bottom limit surface at the bottom of the intersection of the first channel and the second channel in the tooling body.

[0092] Specifically, if Figure 5 As shown, step S540 can be performed, the operator can hold the ejector pin 122 in one hand, extend it downward along the ejector pin hole 111 from above the heating plate 110, and hold the tool body 210 in the other hand, and receive it below the heating plate 110, so that the ejector pin 122 can be radially extended into the center of the weight 121 in the tool body 210, and reach the bottom limit surface 243 located at the bottom of the intersection 240. Then, step S550 can be performed, and the ejector pin 122 can be slightly rotated to rotate the channel of the pin hole 1220 in the ejector pin 122 to be in the same straight line with the first channel 241, so that the pin 123 can be pushed into the pin hole 1220 more accurately. Optionally, step S550 can also be performed in the subsequent process of pushing the first stud 220 to install the pin 123.

[0093] Afterwards, please continue to return to Figure 4 The installation method of the weight ejector pin may further include step S430: inserting the first stud into the first channel to push the latch into the latch hole of the ejector pin through the first channel to complete the assembly of the ejector pin and the weight ejector pin.

[0094] Specifically, combined Figure 3A and Figure 5 As shown, in some optional embodiments, the top of the first channel 241 exceeds the intersection 240 by a first preset length L1, wherein the first preset length L1 may be less than the length of the latch 123, and a first pin limiting surface 310 is provided on the outer side of the intersection 240. In step S560, the first stud 220 is pushed from the outside to drive the latch 123 to be inserted into the latch hole 1220 of the ejector pin 122 until the latch 123 contacts the top of the first channel 241, so that the latch 123 is fully matched with the ejector pin 122. It can be understood that the top of the first channel 241 is equivalent to the third pin limiting surface, which is used to ensure that the latch 123 reaches the optimal assembly position during the installation process.

[0095] Further, in some preferred embodiments, due to the space limitation of the heating plate 110, the installation and removal process of the weight pin 120 has a certain blind adjustment component, so the inner wall of the latch hole 1220 can be provided with an internal thread, and the outer wall of the latch 123 can be provided with an external thread of corresponding size, so that the latch 123 and the pin 122 can be threadedly connected to form a detachable fixed connection relationship. In this regard, the above step S560 can further include rotating and pushing the first stud 220 to drive the latch 123 to rotate and insert into the latch hole 1220, so that the latch 123 and the pin 122 are threadedly connected. Then, the push-in process of the latch 123 can be determined by the number of turns of the threaded connection between the latch 123 and the pin 122, that is, the degree of screwing of the first stud 220 and the second stud 230. When the number of matching turns of the threaded connection reaches the first preset number of turns, it can be determined that the latch 123 has been rotated and pushed into the optimal assembly position.

[0096] Furthermore, in some preferred embodiments, the end faces of the first stud 220 and the second stud 230 can be provided with a first snap-fit ​​structure, and correspondingly, the end face of the pin 123 can also be provided with a second snap-fit ​​structure matching therewith, so that the end faces of the first stud 220 and the second stud 230 can be snap-fitted with the end faces of the pin 123 respectively. The step of threading the latch 123 and the ejector pin 122 may further include inserting the end face of the first stud 220 into the first channel 241 so that the end face of the first stud 220 and the end face of the latch 123 can be engaged with each other via the first engaging structure and the second engaging structure, so that the operator can directly push the first stud 220 through external rotation to drive the latch 123 located inside the tooling body 210 to rotate and move, thereby realizing that the latch 123 is screwed into the latch hole 1220 of the ejector pin 122, so that the latch 123 is threadedly connected to the ejector pin 122, thereby realizing the blind installation of the latch 123 in the heavy hammer ejector pin 120.

[0097] Continue as Figure 5 As shown, in some embodiments, after completing the step of assembling the ejector pin 122 and the weight 121, step S570 can be executed, and the loading and unloading tool 200 can be moved downward so that the pin 123 inserted into the pin hole 1220 falls into the interior of the weight 121, and the loading and unloading tool 200 is moved out, thereby completing the assembly of the ejector pin 122 and the weight 121.

[0098] Next, see Figure 6 , Figure 6 The flowchart of a method for disassembling a heavy hammer ejector pin provided in some embodiments of the present invention is shown. Figure 7 Common understanding, Figure 7 A schematic diagram showing the process of a method for disassembling a weight ejector pin provided according to a specific embodiment of the present invention is shown.

[0099] like Figure 6 As shown, in some embodiments of the present invention, the method for disassembling the weight ejector pin may include the following steps. First, step S610 may be executed: placing the loading and unloading tool for the weight ejector pin under the ejector pin hole of the heating plate so that the weight in the weight ejector pin falls into the groove portion of the tool body.

[0100] Specifically, if Figure 7 As shown, step S710 can be performed first to remove the first stud 220 used for installation from the first channel 241 to avoid interference with the subsequent disassembly process. After the preparation work is completed, step S720 can be performed, and the operator can hold the handle of the ejector pin 122 with one hand and move the tool body 210 with the other hand to make the weight 121 at the bottom of the weight ejector pin 120 fall into the groove portion 211.

[0101] Then, please continue to return to Figure 6 The method for disassembling the weight ejector pin may further include step S620: moving the tool body upward so that the ejector pin in the weight ejector pin reaches a bottom limit surface at the bottom of the intersection of the first channel and the second channel in the tool body.

[0102] Specifically, if Figure 7 As shown, step S730 can be performed, and the tool body 210 can be slowly moved upward so that the ejector pin 122 in the weight ejector pin 120 reaches the bottom limit surface 243 located at the bottom of the intersection 240 in the tool body 210, that is, the target disassembly position. Then, the ejector pin 122 that reaches the bottom limit surface 243 can be gently rotated to rotate the latch pin 123 in the latch pin hole 1220 to be in the same straight line with the second channel 242, that is, to be located in the detachable limit groove.

[0103] Afterwards, please continue to return to Figure 6 The method for disassembling the weight ejector pin may further include step S630: inserting a second stud into the second channel to push the latch away from the latch hole of the ejector pin via the second channel, thereby completing the disassembly of the weight ejector pin.

[0104] Specifically, combined Figure 3B and Figure 5As shown, in some optional embodiments, the top of the second channel is pulled beyond the intersection 240 by a second preset length, wherein the second preset length L2 may be greater than or equal to the length of the plug 123, and a second pin limiting surface 320 is provided on the inner side of the intersection 240, wherein the distance between the second pin limiting surface 320 and the intersection 240 is greater than or equal to the length of the plug 123. In step S740, the second stud 230 is pushed from the outside to drive the plug 123 forward, push the plug 123 away from the plug hole 1220, and enter the top of the second channel 242 to temporarily store and completely accommodate the plug 123 that has been pushed out of the plug hole of the ejector 122 when the heavy hammer ejector 120 is disassembled, thereby preventing the plug 123 from falling or being lost during the disassembly process. Further, when the top of the plug 123 contacts the second pin limiting surface 320, it can be ensured that the plug 123 is completely released from the ejector 122.

[0105] Further, in some preferred embodiments, due to the space limitation of the heating plate 110, the installation and removal process of the weight pin 120 has a certain blind adjustment component, so the inner wall of the latch hole 1220 can be provided with an internal thread, and the outer wall of the latch 123 can be provided with an external thread of corresponding size, so that the latch 123 and the pin 122 can be threadedly connected to form a detachable fixed connection relationship. In this regard, the above step S740 can further include rotating and pushing the second stud 230 to drive the latch 123 to rotate out of the latch hole 1220 and release the threaded connection between the latch 123 and the pin 122. Then, the pushing progress of the latch 123 can be determined by the number of turns of the threaded connection between the latch 123 and the pin 122, that is, the degree of screwing of the first stud 220 and the second stud 230. When the number of matching turns of the threaded connection reaches the second preset number of turns, it can be determined that the latch 123 has been rotated and pushed into the optimal disassembly position.

[0106] Furthermore, in some preferred embodiments, the end faces of the first stud 220 and the second stud 230 can be provided with a first snap-fit ​​structure, and correspondingly, the end face of the pin 123 can also be provided with a second snap-fit ​​structure matching therewith, so that the end faces of the first stud 220 and the second stud 230 can be snap-fitted with the end faces of the pin 123 respectively. The above-mentioned step of releasing the threaded connection between the latch pin 123 and the ejector pin 122 may further include inserting the end face of the second stud 230 into the second channel 242, so that the end face of the second stud 230 and the end face of the latch pin 123 can be engaged with each other via the first engaging structure and the second engaging structure, so that the operator can directly push the second stud 230 through external rotation to drive the latch pin 123 located inside the tooling body 210 to rotate and move, thereby realizing that the latch pin 123 is screwed out of the latch pin hole 1220 of the ejector pin 122, releasing the threaded connection between the latch pin 123 and the ejector pin 122, and realizing the blind removal of the latch pin 123 in the heavy hammer ejector pin 120.

[0107] Continue as Figure 7 As shown, step S750 can be performed afterwards, the second stud 230 can be screwed out, and the ejector pin 122 that has been released from the mating relationship with the weight 121 can be slowly lifted up to be removed from the heating plate 110. Finally, step S760 can be performed to take out the loading and unloading tool 200 including the disassembled weight 121 and the latch 123 from the bottom of the heating plate 110, thereby completing the disassembly of the weight ejector pin 120.
