Description

Technical Field

[0001] The invention relates to the technical field of welding seal fixtures, in particular to a welding seal fixture for a ceramic shell. Background Art

[0002] Ceramic packaging shells are widely used in device packaging such as hybrid integrated circuits, optoelectronic devices, surface acoustic wave devices, Hall devices, crystal oscillators and solid-state relays due to their superior high air tightness, high thermal conductivity, high moisture resistance, high mechanical strength, high insulation resistance and other properties. The packaging method is to place the chip between the ceramic cover and the ceramic base, and under the specific temperature condition of 800 degrees, the ceramic cover and the ceramic base are fused at the joint to form a whole.

[0003] A sealing fixture is required during the packaging process to form a positioning relationship between the four vertical sides of the ceramic base and the ceramic cover, thereby ensuring that the shape of the ceramic shell after sealing is consistent. Currently, the sealing fixture uses multiple clamping plates to position and fix the ceramic base and the ceramic cover. However, when packaging chips of different sizes and models, the protruding lengths of the four clamping plates need to be adjusted separately. The packaging process generally involves processing multiple sets of ceramic cover plates together with the ceramic base. Adjusting multiple clamping plates will consume a lot of time, thereby reducing production efficiency. Summary of the invention

[0004] In order to overcome the shortcoming that the existing fixture cannot quickly adapt to the sealing processing of ceramic shells of different sizes and models, the present invention provides a ceramic shell sealing fixture which can quickly adjust the clamping size to adapt to the sealing processing of ceramic shells of different sizes and models.

[0005] A ceramic shell sealing fixture includes a mounting plate, a handle and a support plate. Seventeen mounting holes are opened on the mounting plate, one of which is located on the upper left side of the mounting plate, and the remaining sixteen mounting holes are arranged in a four-by-four pattern on the mounting plate. Handles are fixedly arranged on the left and right sides of the mounting plate, and a support plate is fixedly connected to the bottom of the mounting plate. The length of the handle does not exceed 100 mm, that is, the width of the support plate does not exceed 100 mm. The fixture also includes a clamping assembly and an adjustment assembly. A clamping assembly for mounting a ceramic shell is provided in each mounting hole, and an adjustment assembly for adjusting the clamping size of the clamping assembly is provided on the mounting plate.

[0006] Optionally, the clamping assembly includes a shell, a vertical clamp, a transverse clamp, a rack, a fixed shaft and a gear. The shell is clamped at the mounting hole on the mounting plate. A group of vertical clamps and a group of transverse clamps are slidably arranged on the upper part of the shell. A rack is fixedly arranged on the lower side of each transverse clamp and vertical clamp. A fixed shaft is fixedly arranged in the middle of the shell. Two gears are rotatably connected to the upper part of the fixed shaft. The rack fixedly connected to the group of vertical clamps is meshed with the gear located on the upper side, and the rack fixedly connected to the group of transverse clamps is meshed with the gear located on the lower side.

[0007] Optionally, the adjustment assembly includes a fixed seat A, a sliding frame A, a sliding frame B, a cylindrical convex block, an electric push rod, a size module and a square convex block. Eight fixed seats A are fixedly connected to the mounting plate. The sliding frame A is slidably connected between the four fixed seats A on the front and rear sides. The vertical sliding seat can slide left and right on the fixed seat A. The sliding frame B is slidably connected between the four fixed seats A on the left and right sides. The sliding frame B can slide back and forth on the fixed seat. A cylindrical convex block is fixedly provided on the sliding frame A at the position where it cooperates with the vertical clamping plate on the front side. Block, the vertical clamping plate on the front side can be engaged with the circular protrusion, a cylindrical protrusion is also fixedly provided at the matching position of the sliding frame B and the horizontal clamping plate on the right side, the horizontal clamping plate on the right side can be engaged with the circular protrusion, an electric push rod is installed on the upper left side and the upper front side of the shell body at the mounting hole on the upper left of the mounting plate, the telescopic rods of the electric push rod are fixedly connected to the adjacent horizontal clamping plates and vertical clamping plates respectively, four size modules are clamped on the left side of the mounting plate, and a square protrusion is fixedly connected to the middle of the upper part of the shell body at the mounting hole on the upper left of the mounting plate.

[0008] Optionally, the bottom of the size module is magnetically arranged to facilitate stable connection with the bottom through magnetic force, thereby preventing the size module from falling off during transportation.

[0009] Optionally, it also includes a U-shaped top rod, a compression spring A, an arc block and an extrusion rod. The U-shaped top rod is slidably connected to the upper part of the shell, and the compression spring A is connected between the U-shaped top rod and the shell. The front and rear sides of the lower part of the U-shaped top rod are fixedly connected to the arc block in a mirror-like manner, and the bottom of the rack fixedly connected to the transverse clamp is fixedly connected to the extrusion rod.

[0010] Optionally, one end of the squeezing rod away from the connection with the rack is arranged in an arc shape, so as to facilitate squeezing the arc block so that it can be lifted up more stably.

[0011] Optionally, it also includes a fixed seat B, a swing rod and a torsion spring. The vertical clamping plate and the horizontal clamping plate are fixedly connected to the fixed seat B, the swing rod is rotatably connected to the fixed seat B, and a torsion spring is connected between the swing rod and the fixed seat B.

[0012] Optionally, the swing rod is made of hard plastic material to prevent the swing rod from scratching the ceramic shell when the ceramic shell is installed.

[0013] Optionally, it also includes a mounting frame, a U-shaped clamping rod, a compression spring B and an L-shaped plate. The bottom of the mounting plate is fixedly connected to the mounting frame at the mounting hole, and two U-shaped clamping rods are slidably connected to the front and rear sides of the mounting frame.

[0014] Optionally, a protective plate is also included, and a protective plate for protecting the sliding frame A and the sliding frame B is installed on the mounting plate.

[0015] Through the above scheme, the beneficial effects achieved by the present invention are:

[0016] 1. By setting the clamping assembly and the pushing assembly, when the size of the ceramic shell needs to be changed, the user puts the size module into the square protrusion and starts the electric push rod. The electric push rod drives the horizontal clamping plate and the vertical clamping plate on the shell at the upper left corner of the mounting plate to move toward the middle, and quickly clamps the size module. At this time, the vertical clamping plates and the horizontal clamping plates on other shells are pushed by the sliding frame A and the sliding frame B for rapid positioning, which is convenient for the rapid installation of ceramic shells of different models and sizes.

[0017] 2. When the transverse clamps located on the same shell move away from each other, the transverse clamps drive the extrusion rod to move through the rack connected thereto, thereby pushing the arc block to make the U-shaped push rod move upward, thereby lifting the processed ceramic shell upward for a certain distance, making it easier to remove the ceramic shell after processing.

[0018] 3. When the user presses the ceramic shell downward between the horizontal clamping plate and the vertical clamping plate, the ceramic shell contacts and squeezes the swing rod, and the torsion spring is compressed, thereby applying an upward force to the ceramic shell through the swing rod, thereby preventing the user from quickly pressing the ceramic shell between the horizontal clamping plate and the vertical clamping plate and colliding with the shell, thereby causing the low-temperature molten glass at the sealing part of the ceramic shell to be crushed, resulting in a worse sealing effect. At the same time, when the ceramic shell is installed, the swing rod applies a horizontal clamping force to the ceramic shell to increase the clamping stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0033] Example 1

[0034] A ceramic shell sealing fixture, such as Figure 1-Figure 12As shown, it includes a mounting plate 1, a handle 3 and a support plate 11, seventeen mounting holes 2 are opened on the mounting plate 1, one mounting hole 2 is located on the upper left side of the mounting plate 1, and the remaining sixteen mounting holes 2 are arranged in a four-by-four pattern on the mounting plate 1. The handles 3 are welded on the left and right sides of the mounting plate 1, and the support plate 11 is welded on the bottom of the mounting plate 1. The length of the handle 3 does not exceed 100 mm, that is, the width of the support plate 11 does not exceed 100 mm. It also includes a clamping component 4 and an adjusting component 5. A clamping component 4 for mounting a ceramic shell is provided in each mounting hole 2, and an adjusting component 5 for adjusting the clamping size of the clamping component 4 is provided on the mounting plate 1.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping assembly 4 includes a shell 41, a vertical clamping plate 42, a horizontal clamping plate 43, a rack 44, a fixed shaft 45 and a gear 46. The shell 41 is clamped at the mounting hole 2 on the mounting plate 1. A group of vertical clamping plates 42 and a group of horizontal clamping plates 43 are slidably connected to the upper part of the shell 41. Each horizontal clamping plate 43 and the lower side of the vertical clamping plate 42 are welded to a rack 44. A fixed shaft 45 is welded to the middle part of the shell 41. Two gears 46 are rotatably connected to the upper part of the fixed shaft 45. The above-mentioned rack 44 welded to a group of vertical clamping plates 42 is meshed with the gear 46 located on the upper side, and the above-mentioned rack 44 welded to a group of horizontal clamping plates 43 is meshed with the gear 46 located on the lower side.

[0036] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, the adjustment assembly 5 includes a fixed seat A51, a sliding frame A52, a sliding frame B53, a cylindrical protrusion 54, an electric push rod 55, a size module 56 and a square protrusion 57. Eight fixed seats A51 are welded and connected to the mounting plate 1. The sliding frame A52 is slidably connected between the four fixed seats A51 on the front and rear sides. The vertical sliding seat can slide left and right on the fixed seat A51. The sliding frame B53 is slidably connected between the four fixed seats A51 on the left and right sides. The sliding frame B53 can slide back and forth on the fixed seat. The cylindrical protrusion 54 is welded and connected to the matching position of the sliding frame A52 and the vertical clamping plate 42 on the front side. The vertical clamping plate 42 on the front side can be embedded with the circular protrusion. A cylindrical protrusion 54 is also welded to the joint between the movable frame B53 and the horizontal clamping plate 43 on the right side. The horizontal clamping plate 43 on the right side can be engaged with the circular protrusion. An electric push rod 55 is installed on the upper left side and the upper front side of the shell 41 located at the mounting hole 2 on the upper left of the mounting plate 1 by bolts. The telescopic rod of the electric push rod 55 is welded to the adjacent horizontal clamping plate 43 and the vertical clamping plate 42 respectively. Four size modules 56 are clamped on the left side of the mounting plate 1. The bottom of the size module 56 is magnetically set to facilitate stable connection with the bottom through magnetic force to prevent the size module 56 from falling off during transportation. A square protrusion 57 is welded to the middle of the upper part of the shell 41 located at the mounting hole 2 on the upper left of the mounting plate 1.

[0037] Initially, the telescopic rod of the electric push rod 55 is in a retracted state. At this time, the user removes the size module 56 of the same size as the next batch of ceramic shells to be processed from the left side of the mounting plate 1, and places it in the middle of the upper part of the shell 41 located at the mounting hole 2 in the upper left corner of the mounting plate 1, so that the square protrusion 57 of the size module 56 is engaged, and the electric push rod 55 is started. The electric push rod 55 on the left side pushes the transverse clamping plate 43 welded to it to slide to the right on the upper part of the shell 41, and the transverse clamping plate 43 on the left side slides to the right, driving the rack 44 welded to it to move to the right, thereby driving the rack 44 welded to the transverse clamping plate 43 on the right side to move to the left through the gear 46, and then the transverse clamping plate 43 on the right side slides to the left on the upper part of the shell 41, clamping and fixing the left and right sides of the size module 56. Similarly, the electric push rod 55 on the front side makes the vertical clamping plates 42 on the front and rear sides of the shell 41 move closer to the center, thereby The front and rear sides of 56 are clamped and fixed. Since the vertical clamping plate 42 located on the front side is engaged with the adjacent cylindrical protrusion 54, the sliding frame B53 is driven to slide backward, and then the remaining vertical clamping plates 42 located on the same shell 41 are pushed closer to each other. Similarly, the remaining horizontal clamping plates 43 located on the same shell 41 are also closer to each other. At this time, the clamping size between the vertical clamping plates 42 and the horizontal clamping plates 43 located on the same shell 41 is equal to the size of the size module 56. The user can fix the ceramic shell to be processed between the vertical clamping plates 42 and the horizontal clamping plates 43. After the ceramic shell is installed, the mounting plate 1 can be sent into the sealing instrument for sealing processing. After the processing is completed, the mounting plate 1 is taken out, and the electric push rod 55 is started to retract the telescopic rod of the electric push rod 55, and the fixed clamping of the ceramic shell can be ended. After the processed ceramic shell is taken out, repeat the above steps to perform sealing processing on the next batch of ceramic shells.

[0038] Example 2

[0039] On the basis of Example 1, Figure 1 and Fig. 9 As shown, it also includes a U-shaped push rod 61, a compression spring A62, an arc block 63 and an extrusion rod 64. The U-shaped push rod 61 is slidably connected to the upper part of the shell 41, and a compression spring A62 is connected between the U-shaped push rod 61 and the shell 41. The arc block 63 is mirror-welded on the front and rear sides of the lower part of the U-shaped push rod 61, and the extrusion rod 64 is welded on the bottom of the rack 44 welded to the transverse clamping plate 43. The end of the extrusion rod 64 away from the connection with the rack 44 is arc-shaped, which is convenient for squeezing the arc block 63 so that it can be lifted more smoothly.

[0040] After a batch of ceramic shells are sealed, the user starts the electric push rod 55. The telescopic rod of the electric push rod 55 retracts and drives the transverse clamps 43 located on the same shell 41 to move away from each other. The transverse clamp 43 on the right side moves to the right, thereby driving the extrusion rod 64 to move to the right through the rack 44 welded to the transverse clamp 43, and finally the extrusion rod 64 squeezes the arc block 63, thereby pushing the U-shaped push rod 61 to slide upward, and lifts the processed ceramic shell upward, so that the processed ceramic shell can be removed easily.

[0041] like Figure 1 and Fig.10 As shown, it also includes a fixed seat B71, a swing rod 72 and a torsion spring 73. The fixed seat B71 is welded to the vertical clamping plate 42 and the horizontal clamping plate 43. The swing rod 72 is rotatably connected to the fixed seat B71. The torsion spring 73 is connected between the swing rod 72 and the fixed seat B71.

[0042] When the horizontal clamping plate 43 and the vertical clamping plate 42 are close to the middle to a predetermined clamping size, the user inserts the ceramic shell between the horizontal clamping plate 43 and the vertical clamping plate 42. When the ceramic shell moves downward to contact and squeeze the swing rod 72, the torsion spring 73 is compressed, thereby applying an upward component of force to the ceramic shell through the swing rod 72, thereby preventing the user from quickly pressing the ceramic shell between the horizontal clamping plate 43 and the vertical clamping plate 42 and colliding with the shell 41, thereby causing the low-temperature melting glass at the sealing part of the ceramic shell to be crushed, resulting in a poor sealing effect. At the same time, when the ceramic shell is installed, the swing rod 72 applies a horizontal clamping force to the ceramic shell to increase the clamping stability. The swing rod 72 is made of hard plastic to prevent the swing rod 72 from scratching the ceramic shell when installing the ceramic shell.

[0043] like Figure 1 , Fig.11 and Fig.12 As shown, it also includes a mounting frame 81, a U-shaped clamping rod 82, a compression spring B83 and an L-shaped plate 84. The bottom of the mounting plate 1 is located at the mounting hole 2 and is welded to the mounting frame 81. Two U-shaped clamping rods 82 are slidably connected to the front and rear sides of the mounting frame 81. A compression spring B83 is connected between the U-shaped clamping rod 82 and the mounting frame 81. The bottom of the shell 41 is symmetrically welded to the L-shaped plate 84.

[0044] When the user installs the shell 41 on the mounting plate 1, the shell 41 moves downward, thereby driving the L-shaped plate 84 to move downward. The L-shaped plate 84 moves downward to push the U-shaped clamping rod 82 outward. At this time, the compression spring B83 is compressed. After the L-shaped plate 84 moves downward to disengage from the U-shaped clamping rod 82, the compression spring B83 resets, thereby pushing the U-shaped clamping rod 82 to reset and clamp the L-shaped plate 84, thereby stably fixing the shell 41 on the mounting plate 1 to prevent the shell 41 from loosening when the mounting plate 1 is moved.

[0045] like Figure 1 As shown, a protective plate 9 is also included. The protective plate 9 for protecting the sliding frame A52 and the sliding frame B53 is installed on the mounting plate 1 by bolts.

[0046] The provision of the protection plate 9 prevents the user from accidentally touching the sliding frame A52 or the sliding frame B53 when transporting the installation plate 1, thereby causing the ceramic shell to loosen.

[0047] All of the above components are made of high temperature resistant materials, such as stainless steel, and can be used stably in a relatively high temperature working environment.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
