AI Technical Summary
When manually bonding the lead wires of existing TO-type tube shells, clamping can easily damage the tube shell, and pasting can easily cause sticking and contamination. There is a lack of a fixture that can both fix and protect.
A TO-type tube shell bonding fixture is designed, which adopts a boss, step, vacuum channel and adsorption hole structure. The tube shell is fixed by vacuum adsorption, and the pins are positioned through the notch and center hole to facilitate picking and placing.
The reliable fixation and protection of the tube shell are achieved, and the applicability and operation convenience of the device are improved.

Abstract
Description
Technical Field
[0001] The present invention relates to the field of tube-shell bonding, in particular to a TO-type tube-shell bonding fixture. Background Art
[0002] Existing TO-type packages are typically secured by clamping or gluing during manual wire bonding. Clamping involves clamping the package with a pressure plate, while gluing involves attaching the package to a mounting surface with adhesive. Both methods can have certain impacts on the package: clamping can easily damage the package, while gluing can easily cause contamination. Therefore, a manual bonding fixture that can effectively secure the package while minimizing any impact is urgently needed. Summary of the Invention
[0003] The present invention aims to overcome the deficiencies in the prior art and provides a TO-type tube shell bonding fixture.
[0004] A TO-type tube shell bonding fixture is characterized in that: it includes a shell, a boss is provided on the shell, a step is provided on the boss and corresponds to the tube shell, a center hole is provided on the step and communicates with the shell, an annular vacuum channel is provided in the step, a group of adsorption holes connected to the vacuum channel are evenly distributed on the step, an air pipe, a vacuum switch and a vacuum input pipe are connected in sequence in the shell on one side of the vacuum channel, a branch pipe is also connected to the vacuum switch, a trigger assembly corresponding to the vacuum switch is provided on the shell, and a notch connected to the center hole is provided on the boss and the shell.
[0005] On the basis of the above technical solutions, the following further technical solutions can be provided: The boss is a frustum, the boss, the center hole and the step are coaxially distributed, and the step forms a ring structure.
[0006] The notch is divided into two connected parts, the upper part is located on the thickness surface of the boss and is rectangular, and the lower part is located on the shell and is trapezoidal.
[0007] The trigger assembly includes a button provided on the shell, and a trigger rod corresponding to the vacuum switch is provided at one end of the button.
[0008] Advantages of the invention: The invention has a simple structure and is easy to use. The tube shell is vacuum-adsorbed through the adsorption holes on the step, and the pins on the tube shell are moved out of position through the notch and the center hole, which facilitates the taking and placing of the tube shell and improves the reliability of device fixation and the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a front view of the present invention; Figure 2It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION
[0010] like Figure 1 and 2 As shown, a TO-type tube shell bonding fixture includes a bottle-shaped shell 1, and an integrally formed circular boss 2 extends upward from the upper end of the shell 1.
[0011] The boss 2 is provided with a coaxially distributed step 3 and a center hole 5, an annular vacuum channel 4 is provided in the step 3, and a group of adsorption holes 4a connected to the vacuum channel 4 are evenly distributed on the step 3, and the adsorption holes 4a are distributed on the same circumference.
[0012] An air pipe 7, a vacuum switch 8 and a vacuum input pipe 10 are sequentially connected in the housing 1 on one side of the vacuum channel 4. One end of the vacuum input pipe 10 extends out of the housing 1 and is connected to a vacuum generating device (not shown).
[0013] The vacuum switch 8 is a three-way control valve with a branch pipe 9 connected to the atmosphere. A trigger assembly is mounted on the housing 1, corresponding to the vacuum switch 8. The trigger assembly includes a button 6 mounted on the housing 1, and a trigger rod 6a at one end of the button 6, which mates with the vacuum switch 8. A notch 12 is provided on the boss 2 and the housing 1, connecting to the center hole 5. This notch 12 is divided into two interconnected upper and lower portions. The upper portion, located on the thickness surface of the boss 2, is rectangular, while the lower portion, located on the housing 1, is trapezoidal.
[0014] Place the TO-type tube package on step 3 through notch 12, then press button 6. Trigger rod 6a moves forward to trigger vacuum switch 8, connecting air pipe 7 to vacuum input pipe 10, and creating a negative pressure in vacuum channel 4. The TO-type tube package is then attached to step 3 through suction hole 4a.
[0015] When the bonding is completed, the button 6 is pressed again, and the button 6 pops up, driving the trigger rod 6a to retract the vacuum switch 8 to close the air pipe 7 and connect the branch pipe 9, and connect the vacuum channel 4 to the atmosphere to a positive pressure state. The staff removes the bonded TO-type tube shell, and then places the TO-type tube shell to be bonded on the step 3 to perform the cycle operation.
