Description

Technical Field

[0001] This application belongs to the field of integrated circuit packaging, and specifically relates to a tooling for encapsulating and sealing caps. Background Technology

[0002] In the semiconductor and integrated circuit fields, most cavity-type housings (such as ceramic housings) ultimately require sealing to protect the chip inside. A common sealing process currently involves: first, applying epoxy resin or other sealant to the areas to be bonded on the cap and / or socket (the socket is also called the housing); then aligning the two and applying pressure to complete the assembly; and finally, curing the sealant by heating to achieve a seal.

[0003] The aforementioned sealing process is also known as the capping process. In practice, semiconductor products packaged with cavity-type shells are mostly customized products, mainly produced in small batches with multiple varieties. Therefore, the aforementioned sealing process is mostly carried out manually. However, manual operation makes it difficult to ensure the alignment accuracy of the socket and the cap, resulting in poor product consistency and even product failure in severe cases. At the same time, manual operation also suffers from low processing efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, this application provides a tooling for sealing caps, which aims to improve processing efficiency and improve the alignment accuracy of the cap and the base.

[0005] The tooling for sealing caps provided in this application specifically includes a first mold and a second mold that can be interlocked with each other; the first mold is provided with a plurality of cap receiving slots, which can fix and release caps placed therein; the second mold is provided with a plurality of seat receiving slots, which are used to receive seat tubes, and the plurality of seat receiving slots correspond one-to-one with the plurality of cap receiving slots; when the first mold and the second mold are interlocked, any cap receiving slot is aligned with the corresponding seat receiving slot so that the cap therein is aligned with the seat tube and engaged.

[0006] The tooling provided by the aforementioned solution allows for the placement and fixing of multiple tube caps in the first mold and multiple tube seats in the second mold. After applying adhesive, the two molds are fastened together, enabling high-precision alignment of multiple sets of tube caps / tube seats. In subsequent steps, the fastened upper / lower molds can be moved into an oven to bake and cure the sealant between the tube caps / tube seats. Then, the upper / lower molds can be separated to remove the sealed product.

[0007] In the aforementioned scheme, since the first mold can controllably fix or release the cap contained therein, the cap can be fixed during the process of fastening the two molds to prevent it from falling off; after the two molds have been properly fastened, the cap can be released to facilitate the separation of the two molds and the removal of the sealed product in subsequent steps.

[0008] Optionally, it also includes a first box and a second box; the first mold is detachably mounted on the first box, the second mold is detachably mounted on the second box, and the first box and the second box are rotatably connected; based on the relative rotation of the first box and the second box, the first mold and the second mold can engage with each other.

[0009] In the aforementioned scheme, by operating the first box and the second box, the first mold and the second mold can be accurately fastened together. After the first box and the second box rotate relative to each other and fasten together, the first mold and the second mold installed in the two boxes are also aligned and fastened together. At this time, the fastened first mold and the second mold can be taken out from the first box and the second box for subsequent baking, heating and other steps.

[0010] Optionally, the first housing is provided with a first mold mounting groove; the side wall of the first mold mounting groove is provided with a first pin hole, and the first mold is provided with a second pin hole at the position corresponding to the first pin hole; the tooling also includes a first pin, which can be inserted into the first pin hole and the second pin hole to fix the first mold in the first mold mounting groove.

[0011] In the aforementioned scheme, in order to install and position the first mold and prevent the first mold from falling off when the first box is flipped, a first pin is provided. In practice, the operator can place the first mold in the first mold mounting slot, insert and tighten the first pin, then flip the first box to make it engage with the second box, and then pull out the first pin so that the engaged first mold and the second mold can be disengaged from the first box and the second box.

[0012] Optionally, the first housing is provided with a first mold mounting groove; the bottom of the first mold mounting groove is provided with multiple first negative pressure grooves that are interconnected; the bottom of at least one first negative pressure groove is provided with a first air hole; a negative pressure interface is provided on the outside of the first housing, the negative pressure interface is connected to the first air hole, and is used to connect a negative pressure source.

[0013] In the aforementioned scheme, during use, the first mold is placed in the first mold mounting slot, and then the negative pressure source is activated. The gas in the space formed by the first negative pressure slot and the bottom of the first mold is extracted by the negative pressure source through the first air hole and the negative pressure interface, so that the first negative pressure slot forms a negative pressure area at the bottom of the first mold, thereby causing the first mold to be adsorbed into the first mold mounting slot, preventing the first mold from falling off when the first box body is flipped.

[0014] After the first mold and the second mold are properly engaged, the negative pressure source can be turned off to allow gas to enter the first negative pressure groove, thereby enabling the engaged first mold and the second mold to detach from the first box and the second box.

[0015] Optionally, the negative pressure interface includes a valve. The valve is used to regulate the gas flow rate of the air path consisting of the first negative pressure groove, the first air hole, and the negative pressure interface; in other words, it regulates the rate at which negative pressure is formed and the adsorption strength on the first mold.

[0016] Optionally, the first mold mounting groove is provided with a sealing ring mounting groove, which surrounds multiple first negative pressure grooves; the tooling also includes a sealing ring disposed in the sealing ring mounting groove, with the sealing ring protruding from the opening of the sealing ring mounting groove.

[0017] The aforementioned sealing ring can enhance the airtightness of the first negative pressure groove and its surrounding area, and improve the adsorption effect on the first mold.

[0018] Optionally, a second air hole is provided at the bottom of the cap receiving groove; when the first mold is installed in the first mold mounting groove, any second air hole is connected to multiple first negative pressure grooves.

[0019] In the aforementioned scheme, the air passage of the first negative pressure groove, the first air hole, and the negative pressure interface can be further extended to the bottom of the cap receiving groove. When the cap is placed in the cap receiving groove, the negative pressure source is activated, which can also form a negative pressure between the cap and the cap receiving groove, adsorbing the cap and preventing the cap from falling off during the process of fastening the upper / lower mold (when the upper mold is flipped).

[0020] Optionally, the first mold has multiple interconnected second negative pressure grooves on the side away from the cap receiving groove; any second air hole is connected to the multiple second negative pressure grooves; when the first mold is installed in the first mold mounting groove, the multiple second negative pressure grooves are connected to the multiple first negative pressure grooves.

[0021] In the aforementioned scheme, the second negative pressure groove connects all the cap receiving grooves to the second negative pressure groove through the second air hole. Then, through the connection between the second negative pressure groove and the first negative pressure groove, a closed air passage is formed that sequentially connects the cap receiving groove, the second air hole, the second negative pressure groove, the first negative pressure groove, the first air hole, the negative pressure interface, and finally the negative pressure source, which enables the negative pressure to be extended to the area between all the cap receiving grooves and the bottom of the cap.

[0022] Optionally, the second housing is provided with a second mold mounting groove; the edge of the second housing is provided with at least one notch, and when the second mold is installed in the second mold mounting groove, at least one notch can expose part of the second mold; the side of the second mold away from the tube seat receiving groove and the bottom of the second mold mounting groove are provided with multiple sets of corresponding second mold positioning structures.

[0023] The aforementioned notch facilitates the removal of the first / second mold from the second housing after it has been snapped together, while the second mold positioning structure ensures that the second mold is accurately positioned within the second mold mounting slot.

[0024] Optionally, the first mold is provided with multiple first mold alignment structures; the second mold is provided with multiple second mold alignment structures that correspond one-to-one with the multiple first mold alignment structures; when the first mold and the second mold are engaged, the first mold alignment structure can fit into the corresponding second mold alignment structure so that the cap receiving groove is aligned with the corresponding seat receiving groove.

[0025] The aforementioned first mold alignment structure and second mold alignment structure are used to reliably align the first / second molds and prevent misalignment of the first / second molds during the process of the operator carrying the snap-fit ​​molds to the oven for heating and curing. The tube seat and tube cap can also remain relatively fixed.

[0026] In summary, the tooling provided by the above technical solution can significantly improve the alignment accuracy between the tube shell and the tube cap, thereby increasing the product qualification rate. Moreover, during baking and curing, since the aligned first / second mold is placed as a whole in the oven, it can ensure that the tube shell and the tube cap remain aligned during the curing process, further improving the alignment accuracy of the encapsulation and the product qualification rate.

[0027] The alignment device described above is simple to operate. Compared with manual operation, it can simultaneously perform batch packaging and capping of products, thereby improving processing efficiency. Attached Figure Description

[0043] This application will now be described more fully below with reference to the accompanying drawings. However, this application can be implemented in many different ways and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided herein to make this application more detailed and complete. The same reference numerals denote the same objects throughout the drawings.

[0044] In the specification of this application, when a component / part / structure is referred to as being "connected to" other components / parts / structures, such as "connected to" other components / parts / structures, the component / part / structure can be directly connected to or directly coupled to other components / parts / structures, or there may be an intervening third component / part / structure; in addition, in the embodiments of this application, "connection" mainly refers to mechanical structural connection, and "connection" mainly refers to the direct or indirect formation of an air passage connection with a certain airtightness between grooves (including cavities formed by grooves and other structures), cavities, and pipelines.

[0045] The poor consistency of products packaged with cavity-type shells in existing technologies (hereinafter referred to as "products") is attributed to the following reasons: (1) After applying adhesive to the cap and socket of the cavity-type shell, they are manually aligned and bonded, which results in poor precision; (2) During the heating (baking) process to cure the sealant between the cap and socket, the relative positions of the cap and socket are not restricted, which may lead to misalignment. The aforementioned reasons directly result in poor product consistency, and in severe cases, may even lead to product sealing failure.

[0046] In addition, the manual sealing operation in the existing technology is wasteful of manpower and inefficient.

[0047] In view of the problems and causes in the prior art, this application provides a tooling for sealing caps (hereinafter referred to as "tooling"), which is designed to accurately align the caps and sockets after applying adhesive, and further maintain the relative fixed position of the caps and sockets during the heating (baking) process.

[0048] The tooling provided in this application embodiment includes a first mold 100 and a second mold 200 that can be fastened to each other.

[0049] like Figure 1 As shown, the first mold 100 is provided with a plurality of cap receiving slots 110, which can fix and release caps contained therein.

[0050] like Figure 2 As shown, the second mold 200 is provided with multiple tube seat receiving grooves 210, which are used to receive tube seats. The multiple tube seat receiving grooves 210 correspond one-to-one with the multiple tube cap receiving grooves 110.

[0051] With the first mold 100 and the second mold 200 engaged, any cap receiving groove 110 is aligned with the corresponding seat receiving groove 210 so that the cap and seat are aligned and engaged. Since the areas to be bonded on the cap and / or seat are pre-coated with sealant such as epoxy resin, the cap and seat can be bonded together after they are aligned and engaged, completing the initial assembly. Subsequently, the engaged first mold 100 and second mold 200 can be placed in a heating device such as an oven to cure the sealant, finally completing the assembly of the cap and seat.

[0052] In one embodiment, such as Figure 1 As shown, multiple cap receiving slots 110 are arranged in an array, for example... Figure 1 The 5×7 array shown includes a total of 35 cap receiving slots 110 on a first mold 100.

[0053] In a typical embodiment, the main body of the first mold 100 is a rectangular plate.

[0054] exist Figure 1 In the embodiment shown, the cap receiving groove 110 is circular; however, this application is not limited to this. The shape of the cap receiving groove 110 can be specifically set according to the shape of the encapsulated cap, such as square, rectangle, etc.

[0055] In a typical embodiment, the main body of the second mold 200 is a rectangular plate that is the same as or similar to the main body of the first mold 100 (similar in shape and size), so that the two can be tightly fastened together.

[0056] Considering that the first mold 100 and the second mold 200, which match in shape and size, may be difficult to separate after being engaged, in a preferred embodiment, such as Figure 2 As shown, the second mold 200 has a separation auxiliary groove 230 on at least one side, and more preferably, two separation auxiliary grooves 230 are symmetrically arranged on both sides of the second mold 200. The opening of the separation auxiliary groove 230 faces the outside of the first mold 100 and the second mold 200. The separation auxiliary groove 230 can form a gap between the snap-fit ​​first mold 100 and the second mold 200, which facilitates the separation of the first mold 100 and the second mold 200 from the gap during operation.

[0057] like Figure 2 As shown, the pipe seat receiving groove 210 is arranged in the same array as the pipe cap receiving groove 110, for example... Figure 2 The 5×7 array shown includes a total of 35 tube seat receiving slots 210 on a second mold 200.

[0058] The shape of the tube socket receiving groove 210 can be specifically set according to the shape of the encapsulated tube socket. Preferably, for example... Figure 2 As shown, the top (opening) of the tube seat receiving groove 210 is recessed to a certain depth relative to the top surface of the second mold 200 (the mating surface with the first mold 100). After the first mold 100 and the second mold 200 are mated, the aforementioned recess can provide space for accommodating the product lead-out end, preventing the lead-out end from being damaged by the pressure of the first mold 100 and the second mold 200.

[0059] In a typical embodiment, the aforementioned cap receiving groove 110 and pipe seat receiving groove 210 are arranged on the mold in a centrally symmetrical manner, so that when the first mold 100 is rotated 180° and fastened to the second mold 200, each cap receiving groove 110 and pipe seat receiving groove 210 can still be aligned, reducing operational errors.

[0060] The tooling provided in the embodiments is particularly suitable for ceramic encapsulation, including caps and sockets made of ceramic materials.

[0061] In the aforementioned embodiments, the depths of the cap receiving groove 110 and the seat receiving groove 210 are set such that when the first mold 100 and the second mold 200 are engaged, they can maintain a certain pressure on the cap and the seat.

[0062] In the aforementioned embodiment, the first mold 100 can controllably fix or release the cap contained therein. During the process of fastening the two molds, the cap can be fixed to prevent it from falling off. After the two molds have been properly fastened, the fixing of the cap can be removed, which facilitates the separation of the two molds and the removal of the sealed product in subsequent steps.

[0063] In one embodiment, the cap may also be fixed in the cap receiving groove 110 by friction alone.

[0064] In use, multiple tube caps are placed in the first mold 100 and fixed, and multiple tube seats are placed in the second mold 200. After applying adhesive, the two molds are snapped together, which allows multiple sets of tube caps and multiple sets of tube seats to be aligned with high precision. In subsequent steps, the snapped upper / lower molds can be moved into an oven to bake and cure the sealant between the tube caps and tube seats. Then, the upper / lower molds are separated, and the sealed product can be taken out, completing the capping process.

[0065] In one embodiment, in order to facilitate the engagement of the first mold 100 and the second mold 200, the first mold 100 and the second mold 200 can be directly or indirectly connected by a rotating pair (e.g., a pivot, a hinge, or a hinge), so that the two can rotate relative to each other. In operation, the first mold 100 and the second mold 200 can be laid flat first, and after the tube cap and tube seat are placed, the first mold 100 can be flipped until it engages with the second mold 200.

[0066] like Figure 3 As shown, in a preferred embodiment, it further includes a first housing 10 and a second housing 20.

[0067] The first mold 100 is detachably mounted on the first housing 10, and the second mold 200 is detachably mounted on the second housing 20. The first housing 10 and the second housing 20 are rotatably connected. Based on the relative rotation of the first housing 10 and the second housing 20, the first mold 100 and the second mold 200 can engage with each other.

[0068] In a typical embodiment, such as Figure 3 As shown, the first housing 10 and the second housing 20 are connected to each other by a pivot.

[0069] In a typical embodiment, such as Figure 3As shown, the first box 10 and the second box 20 can open to nearly or reach 180°, which facilitates the insertion of tube caps and tube seats into the first mold 100 and the second mold 200; the first box 10 and the second box 20 can rotate relative to each other and engage with each other, thereby enabling the first mold 100 and the second mold 200 disposed thereon to also engage with each other.

[0070] In a typical embodiment, with the first box 10 and the second box 20, as well as the first mold 100 and the second mold 200 all fastened together, the first box 10 can be detached from the first mold 100. At this time, the first box 10 can be opened (flipped), while the first mold 100 and the second mold 200 remain fastened together. The first mold 100 and the second mold 200 can then be removed as a whole and moved into a heating device for subsequent baking to cure the sealant.

[0071] For ease of operation, in the preferred embodiment, such as Figure 4 As shown, the first box 10 is provided with a handle 18. When the first box 10 and the second box 20 are fastened together, they are shaped like a briefcase, which makes them easy to move.

[0072] Meanwhile, the aforementioned handle 18 also facilitates the flipping of the first box 10 so that it can be fastened to the second box 20.

[0073] In a typical embodiment, the main bodies of the first box 10 and the second box 20 are both cuboids of similar size and shape.

[0074] In a typical embodiment, such as Figure 4 As shown, the first box body 10 is provided with a first mold mounting groove 11. The shape of the first mold mounting groove 11 is the same as or adapted to the first mold 100.

[0075] Preferably, the depth of the first mold mounting groove 11 is equal to the thickness of the first mold 100, so that after installation, the top surface of the first mold 100 is flush with the fastening surface of the first box body 10.

[0076] Typical, such as Figure 4 As shown, the four corners of the first mold mounting groove 11 have process structures for forming the groove.

[0077] To prevent the first mold 100 from falling out of the first mold mounting slot 11 during the flipping process of the first box 10, in a preferred embodiment, such as Figure 4 As shown, the side wall of the first mold mounting groove 11 is provided with a first pin hole 12, and as... Figure 1 As shown, the first mold 100 is provided with a second pin hole 120 at the position corresponding to the first pin hole 12.

[0078] The tooling provided by the embodiment further includes a first pin 300. As Figure 3 shown, the first pin 300 can be inserted into the first pin hole 12 and the second pin hole 120 to fix the first mold 100 in the first mold mounting groove 11.

[0079] During use, the operator can place the first mold 100 in the first mold mounting groove 11, insert and tighten the first pin 300, then flip the first cassette 10 to engage it with the second cassette 20. Subsequently, pull out the first pin 300 so that the engaged first mold 100 can be disengaged from the first cassette 10.

[0080] In a typical embodiment, the first pin 300 may be provided with an external thread, and at least one of the first pin hole 12 and the second pin hole 120 may be provided with a matching internal thread.

[0081] In a typical embodiment, as Figure 4 shown, the outer end of the first pin 300 is thickened for easy gripping by the operator.

[0082] In a preferred embodiment, as Figure 4 shown, the bottom of the first mold mounting groove 11 is provided with a plurality of first negative pressure grooves 13 communicating with each other; the bottom of at least one first negative pressure groove 13 is provided with a first air hole 14; a negative pressure interface 15 is provided on the outside of the first cassette 10, and the negative pressure interface 15 is connected to the first air hole 14 and is used to connect to a negative pressure source.

[0083] In the embodiment, the aforementioned negative pressure source can be selected as a vacuum device such as a vacuum pump.

[0084] In a typical embodiment, in order to enhance the adsorption effect on the first mold 100, the first cassette 10 includes a plurality of first negative pressure grooves 13 arranged in different directions along perpendicular directions to each other. For example, as Figure 4 shown, the plurality of first negative pressure grooves 13 are in an overall "I" shape, or for a larger-sized and heavier first mold 100, the number of first negative pressure grooves 13 can be appropriately increased, such as forming a "king" shape, etc. In an alternative embodiment, the plurality of first negative pressure grooves 13 can also be arranged in an "X" or "plus" shape, "rice" shape, etc.

[0085] The aforementioned first negative pressure grooves 13 are intended to cooperate with the bottom surface of the first mold 100 to form a negative pressure cavity at the bottom of the first mold 100, that is, a negative pressure is formed in the tiny space between the inner bottom surface of the first mold mounting groove 11 and the outer bottom surface of the first mold 100. Therefore, the present application does not limit the specific shape and number of the first negative pressure grooves 13, as long as a sufficiently large negative pressure cavity can be formed at the bottom of the first mold 100.

[0086] In use, the first mold 100 is placed in the first mold mounting groove 11, and then the negative pressure source is turned on. The gas in the space formed by the first negative pressure groove 13 and the bottom of the first mold 100 is drawn away by the negative pressure source through the first air hole 14 and the negative pressure interface 15, so that the first negative pressure groove 13 forms a negative pressure area at the bottom of the first mold 100, thereby causing the first mold 100 to be adsorbed in the first mold mounting groove 11, preventing the first mold 100 from falling off when the first box 10 is flipped.

[0087] In a typical embodiment, the main body of the first mold 100 is drilled multiple times to form an air passage located inside the first mold 100, which connects the first air hole 14 and the negative pressure interface 15.

[0088] In a typical embodiment, the negative pressure interface 15 is connected to the negative pressure source through an external pipeline, and the connection structure between the negative pressure interface 15 and the external pipeline should be rotatable to accommodate the flipping of the first housing 10 during use.

[0089] Before and after the first mold 100 and the second mold 200 are properly engaged, the negative pressure source can be turned off; after the two are engaged for a period of time, the air path connection between the negative pressure source and the negative pressure interface 15 is disconnected, so that gas enters the first negative pressure groove 13, the negative pressure state is released, and the engaged first mold 100 and the second mold 200 can be separated from the first box 10 and the second box 20.

[0090] In a preferred embodiment, the negative pressure interface 15 includes a valve (not shown in the figure). The valve is used to regulate the gas flow rate in the gas path of the first negative pressure groove 13, the first vent 14, and the negative pressure interface 15; in other words, it regulates the rate at which negative pressure is formed and the adsorption intensity on the first mold 100. Specifically, the valve can be configured as a one-way valve with a venting switch.

[0091] In a preferred embodiment, such as Figure 4 As shown, the first mold mounting groove 11 is provided with a sealing ring mounting groove 16. The sealing ring mounting groove 16 is located at the bottom of the first mold mounting groove 11 and surrounds multiple first negative pressure grooves 13. Correspondingly, the tooling also includes a sealing ring (not shown in the figure) disposed in the sealing ring mounting groove 16.

[0092] The aforementioned sealing ring can enhance the airtightness of the first negative pressure groove 13 and its surrounding area, and improve the adsorption effect on the first mold 100. The sealing ring can be an O-ring.

[0093] In a typical embodiment, the sealing ring is embedded in the sealing ring mounting groove 16, and the top surface of the sealing ring slightly protrudes from the top surface of the sealing ring mounting groove 16, that is, the sealing ring protrudes from the opening of the sealing ring mounting groove 16. Thus, after the first mold 100 is installed in the first housing 10, the bottom surface of the first mold 100 and the bottom surface of the first mold mounting groove 11 are separated by the sealing ring, forming a space with a certain degree of airtightness. After the negative pressure source is activated, due to atmospheric pressure, the bottom surface of the first mold 100 is tightly fitted to the sealing ring, creating a negative pressure within the aforementioned space, thereby fixing the first mold 100.

[0094] In a preferred embodiment, the sealing ring is made of an elastic polymer material.

[0095] In the embodiments, the aforementioned implementation of fixing the first mold 100 with pins and the implementation of adsorbing the first mold 100 with negative pressure can be selected individually or both can be used simultaneously.

[0096] To achieve controllable fixing / releasing of the cap in the cap receiving groove 110, in a preferred embodiment, such as... Figure 1 As shown, a second air hole 130 is provided at the bottom of the cap receiving groove 110; when the first mold 100 is installed in the first mold mounting groove 11, any second air hole 130 is connected to multiple first negative pressure grooves 13.

[0097] In a typical embodiment, the second vent 130 is a through hole that extends vertically through the bottom of the cap receiving groove 110 and through the first mold 100.

[0098] In the embodiment, one or more second vents 130 may be provided at the bottom of each cap receiving groove 110. The second vents 130 are preferably located at the center of the cap receiving groove 110, or the multiple second vents 130 are evenly distributed in the area near the center of the cap receiving groove 110.

[0099] In the aforementioned scheme, the air passage of the first negative pressure groove 13, the first air hole 14, and the negative pressure interface 15 can be further extended to the bottom of the cap receiving groove 110. When the cap is placed in the cap receiving groove 110, the negative pressure source is activated, which can also form a negative pressure between the cap and the cap receiving groove 110, adsorbing the cap and preventing the cap from falling off during the process of fastening the upper / lower mold (when the upper mold is flipped).

[0100] In a preferred embodiment, such as Figure 5 and Figure 7As shown, the first mold 100 has multiple second negative pressure grooves 140 connected to each other on the side away from the cap receiving groove 110; any second air hole 130 is connected to the multiple second negative pressure grooves 140; when the first mold 100 is installed in the first mold mounting groove 11, the multiple second negative pressure grooves 140 are connected to the multiple first negative pressure grooves 13.

[0101] In a typical embodiment, such as Figure 7 As shown, the multiple second negative pressure grooves 140 are arranged in a spiral-like manner to connect all the second air holes 130. Based on the same technical concept, the multiple second negative pressure grooves 140 can also be set as, for example, an "S" shape or a serpentine shape.

[0102] In the aforementioned scheme, the shape of the second negative pressure groove 140 allows all the cap receiving grooves 110 to be connected to the second negative pressure groove 140 through the second air hole 130. Furthermore, through the connection between the second negative pressure groove 140 and the first negative pressure groove 13, an air passage is formed that sequentially connects the cap receiving groove 110, the second air hole 130, the second negative pressure groove 140, the first negative pressure groove 13, the first air hole 14, the negative pressure interface 15, and finally to the negative pressure source, enabling the negative pressure to be extended to the area between all the cap receiving grooves 110 and the bottom of the cap.

[0103] In a preferred embodiment, such as Figure 6 As shown, the second box body 20 is provided with a second mold mounting groove 21.

[0104] like Figure 6 As shown, the edge of the second housing 20 is provided with at least one notch 22. When the second mold 200 is installed in the second mold mounting groove 21, at least one notch 22 can expose a part of the second mold 200, such as the bottom surface of the second mold 200. By providing a notch that exposes a part of the second mold 200, it is convenient to remove the first / second mold after it has been fastened from the second housing.

[0105] The side of the second mold 200 facing away from the tube seat receiving groove 210 and the bottom of the second mold mounting groove 21 are provided with multiple sets of corresponding second mold positioning structures 23. In an optional embodiment, each set of second mold positioning structures 23 includes a pair of positioning pins (posts) and positioning holes. For example, a positioning post is provided on the side of the second mold 200 facing the second mold mounting groove 21, and a corresponding positioning hole is provided at the bottom of the second mold mounting groove 21. Similarly, such as Figure 7 As shown, the first mold 200 has multiple sets of first mold positioning structures 160 corresponding to each other on the side opposite to the cap receiving groove 110 and at the bottom of the first mold mounting groove 11. Optionally, the first mold positioning structure 160 includes a pair of positioning pins (posts) and positioning holes.

[0106] The aforementioned second mold positioning structure 23 can accurately place the second mold 200 in the second mold mounting groove 21; the aforementioned first mold positioning structure 160 can accurately place the first mold 100 in the first mold mounting groove 11.

[0107] In a preferred embodiment, such as Figure 1 As shown, the first mold 100 is provided with multiple first mold alignment structures 150; such as Figure 2 As shown, the second mold 200 is provided with a plurality of second mold alignment structures 220 corresponding one-to-one with the plurality of first mold alignment structures 150. When the first mold 100 and the second mold 200 are engaged, the first mold alignment structure 150 can be fitted with the corresponding second mold alignment structure 220 to make the cap receiving groove 110 aligned with the corresponding seat receiving groove 210.

[0108] Optionally, the first mold alignment structure 150 and the second mold alignment structure 220 are respectively matching pins (pillars) and hole structures.

[0109] The aforementioned first mold alignment structure and second mold alignment structure are used to reliably align the first / second molds and prevent misalignment of the first / second molds during the process of the operator carrying the snap-fit ​​molds to the oven for heating and curing. The tube seat and tube cap can also remain relatively fixed.

[0110] In alternative embodiments, such as Figure 4 As shown, the first housing 10 is provided with a first housing alignment structure 17, corresponding to, as Figure 6 As shown, the second housing 20 is provided with a second housing alignment structure 24. Optionally, the first housing alignment structure 17 and the second housing alignment structure 24 are mutually matching pin (post) and hole structures.

[0111] In a preferred embodiment, various alignment and positioning structures, such as the aforementioned first box alignment structure 17 and second box alignment structure 24, first mold alignment structure 150 and second mold alignment structure 220, first mold positioning structure 160 and second mold positioning structure 23, are all in two sets and are arranged along the diagonal of the box / mold.

[0112] In summary, the tooling provided by the above technical solution can significantly improve the alignment accuracy between the tube shell and the tube cap, thereby increasing the product qualification rate. Moreover, during baking and curing, since the aligned first / second mold is placed as a whole in the oven, it can ensure that the tube shell and the tube cap remain aligned during the curing process, further improving the alignment accuracy of the encapsulation and the product qualification rate.

[0113] The alignment device described above is simple to operate. Compared with manual operation, it can simultaneously perform batch packaging and capping of products, thereby improving processing efficiency.

[0114] The above description is only a partial embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the embodiments of this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
