Description

TECHNICAL FIELD

[0001] The application belongs to the field of manufacturing hybrid integrated circuits, and particularly relates to a tube shell bearing jig. BACKGROUND

[0002] In the packaging process of hybrid integrated circuits, the prior art usually adopts the following procedures: (1) forming a metal lead on a substrate, (2) bonding the substrate to a tube shell, (3) mounting the required electronic components to the substrate in the tube shell, (4) bonding to achieve the required circuit function, and (5) sealing and welding the cover plate to the tube shell.

[0003] As described above, procedures (2), (3) and (4) need to be completed one by one inside each product tube shell during the entire packaging process. However, the known automated mounting and bonding equipment (hereinafter referred to as equipment) is not equipped with a jig for bearing a single unsealed product tube shell, which hinders the automatic processing of the internal circuit structure of the tube shell using the above-mentioned equipment.

[0004] In the current packaging process of hybrid integrated circuits, the operator needs to manually load and fix one tube shell (such as a ceramic tube shell) to the automated mounting and bonding equipment for packaging each time, and manually unload one tube shell from the automated mounting and bonding equipment after processing, in other words, only one tube shell can be processed each time; this manual clamping, fixing and unloading operation of the tube shell wastes a lot of time.

[0005] Therefore, there is an urgent need for a special jig suitable for the automated mounting and bonding equipment, which can fix multiple tube shells to improve production efficiency. CONTENT OF THE INVENTION

[0006] To solve or improve the above-mentioned problems existing in the prior art, the application provides a tube shell bearing jig, which specifically comprises a base and a pressing plate.

[0014] By arranging the top surface of the transmission edge to be lower than the top surface of the base body, the position height of the base body can be raised, so that the base body does not collide with other mechanisms below the equipment track during the transmission process. In addition, the transmission edge is arranged at the upper half of the base body, which can increase the distance between the equipment working head and the base body (and the tube shell placed therein), thereby effectively increasing the working distance range of the equipment working head in the vertical direction.

[0015] Optionally, the multiple cavities are arranged in an array; the depth of the cavity is less than or equal to the thickness of the tube shell of the product to be disposed, so that the top end of the tube shell in the cavity protrudes or is flush with the top of the cavity, and the pressing plate can be directly pressed on the edge of the tube shell, thereby preventing the product from shaking during the processing.

[0016] Optionally, the cavity is a rectangular groove or a square groove.

[0017] Optionally, the base body is provided with a taking and placing groove in communication with one or more cavities, facilitating the taking and placing operation of the tube shell before and after processing.

[0018] Optionally, further comprising a plurality of taking and placing grooves arranged along the second direction; any taking and placing groove among them extends along the first direction and communicates with multiple cavities. This optional scheme can reduce the production process of the jig, and one taking and placing groove can realize the effect of facilitating the taking and placing of multiple cavities at the same time.

[0019] Optionally, the bottom of the foregoing cavity is further provided with a negative pressure hole in communication with the cavity, and the negative pressure hole is used to communicate with a negative pressure source, so that a negative pressure or vacuum can be formed at the bottom of the cavity to further adsorb and fix the tube shell.

[0020] Optionally, the limiting groove has a plurality of limiting groove chamfers that are asymmetric along the second direction; the pressing plate has a plurality of pressing plate chamfers corresponding to the plurality of limiting groove chamfers, which can facilitate observation and judgment of the installation of the pressing plate.

[0021] Optionally, one end of the limiting groove is located inside the base body, and the limiting groove extends along the first direction and penetrates one side surface of the base body; in the state that the pressing plate is installed in the limiting groove, one end of the pressing plate is located inside the base body, and the other end is aligned with the aforementioned penetrated side surface of the base body.

[0022] Optionally, the base body is provided with notches at both ends along the first direction, facilitating disassembly and assembly of the pressing plate.

[0023] Optionally, the opening area of the through hole is 10% to 20% smaller than the opening area of the material cavity, so that the pressing plate can be stably pressed on the edge of the tube shell without affecting the internal processing of the tube shell.

[0024] Optionally, the fixing structure specifically comprises a plurality of magnets arranged on the base body; the magnets are dispersedly arranged around the opening of the material cavity, or the magnets are in the form of a long strip extending along the first direction; and the pressing plate is made of a magnetic material and can be adsorbed and fixed on the magnets.

[0025] Optionally, the magnets are in the form of a circle.

[0044] The present application will now be described more fully hereinafter with reference to the accompanying drawings, in which the present application can be implemented in many different ways and should not be construed as being limited to the embodiments set forth herein. Instead, these embodiments are provided so that this application will be thorough and complete, and fully convey the scope of the application to those skilled in the art. Identical reference numerals refer to identical objects throughout the several views

[0045] In order to fully disclose the present application, in the description of the embodiments, "first direction" and "second direction" are defined as reference directions, which can be referred to Figure 2 in the figure, wherein the "first direction", "second direction" and the thickness direction of the tube shell carrying jig are orthogonal to each other.

[0046] In view of the problems in the prior art, the embodiments of the present application provide a tube shell carrying jig (hereinafter referred to as jig for short), as shown in Figure 1 The jig at least includes a base 100 and a pressing plate 200.

[0047] The base 100 and the pressing plate 200 are detachable, the base 100 can accommodate multiple tube shells of products to be disposed, and the pressing plate 200 can fix the aforementioned tube shells when assembled with the base 100. It is understood that the product to be disposed is an unpackaged product, such as an unpackaged infrared micro-electro-mechanical system (MEMS) product.

[0048] Figure 7 And Figure 8 The external features of the base 100 and the pressing plate 200 when assembled with each other are shown respectively.

[0049] As Figure 2 shown, the base 100 specifically includes a base body 110 and a transmission edge 120 arranged outside the base body 110.

[0050] The base body 110 therein is provided with multiple cavities 111 for accommodating tube shells of products to be disposed, and a limiting groove 112 arranged at the opening of the multiple cavities 111 for mounting and positioning the pressing plate 200.

[0051] In typical embodiments, the cavities 111 and the limiting groove 112 are arranged at the top of the base body 110.

[0052] It is understood that the aforementioned "top" of the base body 110 and the similar description hereinafter all represent the side of the jig facing upwards in the usual state of use, such as Figure 2 presented in the side view of the base 100: Figure 4 as indicated by the arrow in the figure, the left side of the base 100 is the "top".

[0053] The limiting groove 112 is used for positioning the pressing plate 200 to avoid movement of the pressing plate 200 relative to the base 100 along the first / second direction, and the limiting groove 112 has a certain depth so that at least part of the pressing plate 200 can be embedded therein, Figure 7 showing the state of installation of the pressing plate 200 embedded in the limiting groove 112.

[0054] As Figure 2 shown, the limiting groove 112 is formed at the top of the base body 110, and the cavities 111 are further formed at the bottom of the limiting groove 112. The area of the limiting groove 112 should cover all the cavities 111, and based on the observation direction in Figure 2 , its projection area should be smaller than the projection area of the top of the base body 110.

[0055] In typical embodiments, the depth direction of the limiting groove 112 and the cavities 111 are both the thickness direction of the jig, both perpendicular to the first / second direction.

[0056] At least part of the edge of the limiting groove 112 should be matched (profiled) with at least part of the edge of the pressing plate 200 to realize the positioning of the pressing plate 200.

[0057] The shape of the base body 110 can be designed according to the specific design of the equipment track structure. For example, it can be designed as a cuboid or a cube.

[0058] The base body 110 has the ability of rapid heat conduction, and the material can be selected from metal or alloy materials with good heat dissipation, such as aluminum (alloy), copper, steel, molybdenum, heat-conducting plastic / composite materials, etc.

[0059] In a typical embodiment, the outer contour of the base body 110 is a cuboid, and the long edges are along the first direction. Correspondingly, the limiting groove 112 is also a long slot with the length direction along the first direction.

[0060] As shown in the side view of the base 100: Figure 2 The transmission edge 120 extends along the first direction and is arranged on the two edges of the base body 110 along the second direction.

[0061] In a typical embodiment, the outer contour of the base body 110 is a cuboid, and the long edges are along the first direction. Correspondingly, the transmission edge 120 is arranged on the outside of the two long edges of the jig, i.e. above and below the jig in the embodiment of the base 100, and extends along the long edge in the first direction. Figure 2

[0062] In a preferred embodiment, the transmission edge 120 occupies the entire length of the edge.

[0063] The foregoing limiting groove 112 is only used to determine the relative position of the pressing plate 200 and the base 100, and further, in order to fix them to limit the tube shell of the product to be disposed in the jig, the jig provided by the embodiment further comprises a fixing structure for fixing the base body 110 and the pressing plate 200, which should be convenient to disassemble, such as a magnetic structure capable of adsorbing the base body 110 and the pressing plate 200, or a screw hole / through hole structure and a matching screw arranged on the base body 110 and the pressing plate 200, etc.

[0064] As shown in the side view of the base 100: Figure 3 The pressing plate 200 is provided with a plurality of through holes 211, and in the state that the pressing plate 200 is installed in the limiting groove 112, due to the positioning of the limiting groove 112 on the pressing plate 200, the plurality of through holes 211 on the pressing plate can accurately correspond to the plurality of cavities 111 on the base, and in an ideal state, the geometric centers of the corresponding cavities 111 and through holes 211 should be aligned with each other.

[0065] In a preferred embodiment, as shown in the side view of the base 100: Figure 4 The thickness of the transmission edge 120 is less than the thickness of the base body 110.​

[0066] In a typical embodiment, as shown in Figure 4 the transmission edge 120 is arranged at the upper half of the base body 110 (i.e. arranged at the left side of the figure, close to the top of the base 100) along the thickness direction of the base body 110. This design increases the distance between the equipment work head and the base body 110 (and the tube shell therein) during the mounting and bonding process, thereby effectively increasing the working distance range of the equipment work head in the thickness direction of the jig.

[0067] In an embodiment, the top surface of the transmission edge 120 is flush with the top surface of the base body 110 (not shown in the figure), or as shown in Figure 4 the top surface of the transmission edge 120 is lower than the top surface of the base body 110.

[0068] The aforementioned top surface of the base body 110 is the uppermost plane of the base body 110 in the use state, as shown in Figure 2 and Figure 4 In a typical embodiment, the top surface of the base body 110 is the upper surface of the protruding portion of the base body 110 surrounding the limiting groove 112.

[0069] During the mounting and bonding process, the transmission edge 120 can be placed on the equipment track. By arranging the top surface of the transmission edge 120 to be lower than the top surface of the base body 110, the position height of the base body 110 can be raised, so that the base body 110 does not collide with other mechanisms below the equipment track during the transmission process.

[0070] In a typical embodiment, the transmission edge 120 is in the form of a thin sheet, and the thickness thereof can be designed to be within the range of 0.5mm to 1mm. The length of the transmission edge 120 can be equal to or shorter than the length of the base body 110.

[0071] In a typical embodiment, the transmission edge 120 and the base body 110 can be an integral structure, i.e. both are formed from the same raw material and are machined into shape.

[0072] Alternatively, the transmission edge 120 can also be obtained separately and fixed to the base body 110 by means of welding or the like.

[0073] In a preferred embodiment, as shown in Figure 2 a plurality of cavities 111 are arranged in an array on the top surface of the base body 110; the cavities 111 are rectangular grooves with a depth less than or equal to the thickness of the tube shell of the product to be processed, so that after the tube shell is placed in the cavity 111, the top of the tube shell slightly protrudes from the top of the cavity or is flush with the top of the cavity, allowing the pressing plate 200 to be directly pressed on the edge of the tube shell, thereby preventing the product from shaking during processing.

[0074] Typically, multiple cavities 111 are arranged in a rectangular array, for example Figure 2 The fixture is arranged in a 2x6 grid, with 12 cavities 111 on each fixture. In some embodiments, the distance between adjacent cavities 111 may be the same or different.

[0075] Correspondingly, such as Figure 3 As shown, the through holes 211 on the pressure plate 200 are also arranged in a 2-row, 6-column configuration, with a total of 12 through holes 211. The row spacing and column spacing are consistent with the material cavity 111.

[0076] For the automated mounting and bonding equipment applicable to the embodiments, in addition to the aforementioned track, a conveying device for transporting fixtures may also be provided on it, which is usually a conveyor belt arranged along a preset direction, or a set of conveyor wheels, a set of conveyor rollers, etc.

[0077] In one embodiment, the conveying device is a conveyor belt with the conveying direction arranged along a first direction. The conveying edge 120 can be placed on the aforementioned conveyor belt, and the conveyor belt drives the conveying edge 120 to move, thereby driving the fixture to move.

[0078] In another embodiment, the conveying device is a set of conveying wheels (transfer rollers) arranged in the first direction, and includes multiple pairs of conveying wheels (transfer rollers) facing each other. The thin-sheet conveying edge 120 is clamped between the upper and lower conveying wheels (transfer rollers). By rotating the conveying wheels (transfer rollers), the conveying edge 120 is driven to move, thereby driving the fixture to move.

[0079] In the foregoing embodiment, considering the driving of the aforementioned conveying device, the direction of movement of the fixture is as follows: Figure 2 The first direction (i.e., the same as the extension direction of transmission edge 120) in the array of material holes means that the number of material holes arranged in the first direction should be larger, while the number of material holes arranged in the second direction should be smaller. In other words, the number of material holes arranged in the first direction should be smaller. Figure 2 Taking the direction shown as an example, the number of columns in the material cavity array should be greater than the number of rows, such as 2 rows and 6 columns, 2 rows and 8 columns, 1 row and 6 columns, 1 row and 8 columns, etc.

[0080] In this embodiment, the shape of the hopper 111 is determined according to the shape of the casing of the product to be processed, such as a rectangle or a square.

[0081] In one embodiment, the bottom of the material cavity 111 may be closed. In another embodiment, the material cavity 111 may be a blind hole, or the bottom of the material cavity 111 may be hollowed out, but it must be ensured that the tube shell will not come out of the hollowed-out hole.

[0082] like Figure 5 As shown, the corners of the material cavity 111 may have chamfers, rounded corners, or unavoidable process structures, which will not be elaborated in this application.

[0083] In a preferred embodiment, as shown in Figure 5 the base body 110 is further provided with a taking and placing groove 113 communicating with one or multiple cavities 111, so as to provide the user with the operation space on both sides of the tube shell, facilitating the taking and placing of the tube shell before and after processing.

[0084] In an embodiment, the depth of the taking and placing groove 113 can be less than or equal to the depth of the cavity 111.

[0085] In a typical embodiment, as shown in Figure 2 the taking and placing groove 113 comprises multiple parallel taking and placing grooves 113 arranged along the second direction; any taking and placing groove 113 extends along the first direction and communicates with multiple cavities 111. Specifically, as shown in Figure 2 the taking and placing groove 113 is arranged along the row direction of the cavity array, and each row of cavities is communicated by one taking and placing groove 113, and the number of taking and placing grooves 113 is the same as the number of rows of the cavity array.

[0086] It should be understood that the aforementioned taking and placing groove 113 includes the sections between the adjacent two cavities 111 in a row and the sections outside the cavities 111 at both ends, in other words, the definition of "one" cavity in the embodiment refers to the cavity formed by the same machining process, for example, as shown in Figure 2 the upper row of 6 cavities is cut along the first direction by a milling cutter to form multiple taking and placing groove sections between adjacent cavities and at both ends, which together constitute the first taking and placing groove; similarly, the lower row of 6 cavities is also cut along the first direction to form the second taking and placing groove.

[0087] In an embodiment, as shown in Figure 5 the taking and placing groove 113 penetrates the cavity 111 at the end of a row and further extends a distance away from the end, for example, forming Figure 5 the arc-shaped groove structure on the right side of the cavity 111, which can ensure that the cavities 111 at the ends of the row / column also have operation space on both sides of the tube shell.

[0088] In a typical embodiment, the length direction of the taking and placing groove 113 is along the first direction; the width direction is along the second direction; the depth direction is the same as the thickness direction of the jig, as well as the depth direction of the cavity 111 and the limiting groove 112.

[0089] In a preferred embodiment, in order to better fix the tube shell, as shown in Figure 5 the bottom of the cavity 111 is provided with a negative pressure hole 114 for communicating with a negative pressure source.

[0090] In typical embodiments, the negative pressure hole 114 is connectable to a negative pressure pipeline, which is in turn connectable to a negative pressure source, such as a vacuum pump, so that the negative pressure formed by the negative pressure source causes the tube shell to be adsorbed to the bottom of the material pocket 111.

[0091] In typical embodiments, the aforementioned negative pressure pipeline can be formed inside the base body 110, such as by drilling or other processes, to form a unified negative pressure interface on the bottom surface or side wall of the base body 110, facilitating centralized connection with the negative pressure source.

[0092] In preferred embodiments, in order to avoid the pressing plate 200 being installed in reverse and improve work efficiency, the limiting groove 112 has a plurality of limiting groove chamfers that are asymmetric along the second direction. Specifically, as shown in Figure 2 the limiting groove 112 has two limiting groove chamfers 1121 opposite along the second direction, and the two limiting groove chamfers 1121 have geometric shape / size differences, constituting the asymmetry of the two limiting groove chamfers 1121 along the second direction.

[0093] Typically, for example Figure 2 the radius of the upper limiting groove chamfer 1121 is greater than the radius of the lower limiting groove chamfer 1121.

[0094] Correspondingly, as shown in Figure 3 the pressing plate 200 has a plurality of pressing plate chamfers 221 corresponding to the plurality of limiting groove chamfers 1121, and when the radius of the upper limiting groove chamfer 1121 is greater than the radius of the lower limiting groove chamfer 1121, the radius of the upper pressing plate chamfer 221 is greater than the radius of the lower pressing plate chamfer 221.

[0095] It should be understood that although the aforementioned features are named as "chamfers" in the embodiments, this does not constitute a specific shape limitation on the aforementioned corners, and the aforementioned corners can also be rounded or other process forms, as long as the shape / size of the two opposite corners along the second direction is asymmetric, which meets the requirements.

[0096] In preferred embodiments, as shown in Figure 2 one end of the limiting groove 112 is located inside the base body 110, i.e. Figure 2 in the case of being close to the left side edge of the base body 110 and still maintaining a certain distance from the left side edge of the base body 110.

[0097] Further, as shown in Figure 2 the limiting groove 112 extends along the first direction (to the right side) and penetrates through one side (edge) of the base body 110.

[0098] In other words, one edge of the limiting groove 112 is aligned with the edge of the base body 110, and the other edge of the limiting groove 112 is located inside the base body 110. The area of the limiting groove 112 is smaller than the top surface area (the projected area perpendicular to the thickness direction) of the base body 110.

[0099] In a typical embodiment, the limiting groove 112 includes a bottom surface and three side surfaces, i.e. Figure 2 the upper side surface, the lower side surface, and the left side surface shown in FIG. 2, the limiting groove 112 positions the pressing plate 200 through at least two of the aforementioned upper side surface, lower side surface, and left side surface, so as to prevent the pressing plate 200 from moving relative to the base 100 in the first / second direction. The right end of the limiting groove 112 is open to the right side because it penetrates the base body 110.

[0100] In a typical embodiment, the shape and size of the pressing plate 200 are the same as those of the limiting groove 112 in the projection perpendicular to the thickness direction. In the state where the pressing plate 200 is installed in the limiting groove 112, one end of the pressing plate 200 is located inside the base body 110, and the other end is aligned with the edge of the base body 110. The end of the pressing plate 200 that is aligned with the edge of the base body 110 can be easily taken out and placed.

[0101] In an embodiment, according to the depth of the limiting groove 112, the pressing plate 200 can be completely embedded in the limiting groove 112 in the thickness direction, or a part of the pressing plate 200 can protrude, i.e. the depth of the limiting groove 112 can be less than or equal to the thickness of the pressing plate 200.

[0102] In a preferred embodiment, as shown in FIG. 2, Figure 2 the base body 110 is provided with notches 115 at both ends in the first direction. The notches 115 can be "U" shaped.

[0103] In a typical embodiment, as shown in FIG. 2 or Figure 6 or Figure 8 when the pressing plate 200 is installed in the limiting groove 112, a part of the pressing plate 200 is exposed from the notches 115 due to the provision of the notches 115. This part is convenient for the user to operate to disassemble the pressing plate 200.

[0104] The opening area of the through hole 211 is smaller than the opening area of the material cavity 111. In a typical embodiment, the opening area of the through hole 211 is 10% to 20% smaller than the opening area of the material cavity 111. This design is to enable the pressing plate 200 to stably press against the edge of the tube shell without affecting the processing inside the tube shell.

[0105] Specifically, if the through hole 211 is too small (20% or more smaller in area) relative to the pocket 111, the machining of the inside of the tube shell can be blocked or hindered; if the opening area of the through hole 211 is too close to or the same as (within 10% in area) the opening area of the pocket 111, the tube shell can be unstable and even fall out of the through hole 211.

[0106] In a typical embodiment, as shown in Figure 5 the fixing structure specifically includes a plurality of magnets 130 arranged on the base body; the plurality of magnets 130 are dispersedly arranged around the opening of the pocket 111, and the magnets 130 can be circular, for example, the plurality of magnets 130 are dot-shaped and arranged at four corners outside each pocket 111.

[0107] In another embodiment, the fixing structure is a long strip-shaped magnet extending in the first direction, and the number of magnets can be one or more, and preferably, the aforementioned long strip-shaped magnet is arranged between each row in the pocket array.

[0108] Correspondingly, the pressing plate 200 is made of a magnetic material, such as iron, nickel, etc., so that the aforementioned magnet can be adsorbed and fixed.

[0109] The fixing mechanism can also be other mechanisms, such as bolts, etc., which can fix the pressing plate 200 on the base body 110.

[0110] The aforementioned jig can realize synchronous feeding of a plurality of tube positions (depending on the number of pockets), synchronous bonding of chips, and bonding. The operator only needs to place the tube shells into the pockets of the jig one by one and place the pressing plate, and then place it into the feeding unit of the equipment, and start the equipment, and the equipment can automatically complete the feeding action.

[0111] The following exemplary provides a working procedure for processing using the aforementioned jig:

[0112] 1. Remove the pressing plate.

[0113] 2. Place the tube shells into the pockets one by one.

[0114] 3. Fix the pressing plate in the limiting groove.
