Description

TECHNICAL FIELD

[0001] The utility model relates to a vacuum glass production technical field, concretely is a kind of getter feeding device for vacuum glass production line. BACKGROUND

[0002] Bulb products are mostly in vacuum or inert gas state to work and emit light. To ensure the normal work of the product, high vacuum or pure working gas must be obtained. If the vacuum hygiene is not good during production, dust, soot, grease, sweat stains, moisture and other impurity gases will enter the bulb interior to form pollution, which seriously affects the product quality. Therefore, the lamp needs to be vacuum treated before production. In the process of vacuum treatment, getter is used to obtain, maintain vacuum and purify gas, so as to improve the vacuum degree of vacuum space in a short time and maintain the required vacuum for a long time.

[0003] The getter feeding device for vacuum glass production line with the application number 201911015303.X includes a rotary drive shaft, a drive motor, a rotary taking device and a storage device. The rotary drive shaft is connected with the drive motor. The rotary taking device includes a fixed inner disc, a rotary taking disc and a fixed outer disc. The rotary taking disc is placed between the fixed inner disc and the fixed outer disc, and the rotary drive shaft is connected with the rotary taking disc. The fixed inner disc is provided with a piece supply hole and a spring piece hole, the rotary taking disc is provided with a piece taking hole, and the fixed outer disc is provided with a heating station hole and a shell removing station hole. The storage device includes a storage tube, which is hollow inside. The storage tube is closed at one end outside the vacuum chamber and connected with the fixed inner disc at the other end corresponding to the piece supply hole. The storage tube is provided with a spring, and the getter piece is placed in the storage tube and pressed by the spring. The present application can realize online supply of getter, and quickly activate the getter by high-frequency heating method, so that the tempering performance of vacuum glass is not degraded by large-area, long-time and high-temperature heating.

[0004] Although the technical solution is convenient for supplying getter to vacuum glass, the structure type and operation mode make it not suitable for ring-shaped or semi-closed structure of lamp tube. The rotary taking disc is difficult to enter the lamp tube to supply getter. If the size of the rotary taking disc is reduced, the size of the getter that can be transported is also small, which affects the processing efficiency of vacuum glass lamp tube.

[0005] Therefore, the utility model aims to provide a getter feeding device for vacuum glass production line to solve the technical problems mentioned in the background.

[0006] In order to achieve the above object, the utility model provides the following technical scheme: a getter feeding device for vacuum glass production line, including the shell, the shell inside one side is installed the cylinder, and the cylinder output end is connected with the drag bucket, the drag bucket top side is connected with the sliding plate, the drag bucket bottom is provided with the recess, the shell inside one side is fixed with the limiting frame, and the limiting frame is connected with the stop plate through the torsional spring shaft in the inside.

[0007] By adopting the above technical scheme, the getter main body is affected by gravity and falls on the drag bucket, the drag bucket is displaced by the cylinder to make the drag bucket enter the vacuum glass main body, at the same time of displacement of the drag bucket, the getter main body will abut against the stop plate to make the stop plate rotate downward along the vacuum chamber direction, thereby avoiding that the stop plate affects the movement of the getter main body, and the drag bucket drives the displacement of the sliding plate, the length of the sliding plate is relatively long and can shield the getter main body in the storage cylinder, avoiding that the getter main body in the storage cylinder falls in the shell.

[0008] Further, the width of the recess is greater than the width of the stop plate.

[0009] By adopting the above technical scheme, since the width of the recess is greater than the width of the stop plate, the drag bucket cannot be retracted when the stop plate abuts against the drag bucket.

[0010] Further, the top of the shell is connected with the storage cylinder, and the top of the storage cylinder penetrates the sealing cover, and the storage cylinder and the drag bucket are respectively provided with a plurality of getter main bodies.

[0011] By adopting the above technical scheme, the staff opens the sealing cover to put the getter main body into the storage cylinder and reassembles the sealing cover, so as to supply the getter to the vacuum glass main body.

[0012] Further, the getter main body is detachably connected with the drag bucket, and the getter main body is slidably connected with the sliding plate.

[0013] By adopting the above technical scheme, the getter main body is affected by gravity and falls on the drag bucket, the drag bucket is displaced by the cylinder to make the drag bucket enter the vacuum glass main body, and the drag bucket drives the displacement of the sliding plate, and the length of the sliding plate is relatively long and can shield the getter main body in the storage cylinder, avoiding that the getter main body in the storage cylinder falls in the shell.

[0014] Further, the getter main body and the stop plate abut against each other, and the stop plate is rotationally connected with the limiting frame through the torsional spring shaft.

[0015] By adopting the technical scheme, the getter main body can abut against the abutment plate when the drag bucket is displaced, so that the abutment plate is rotated downward along the direction of the vacuum chamber, thereby avoiding the influence of the abutment plate on the movement of the getter main body.

[0016] Further, the limiting frame is in the shape of an "L" in cross section, and the abutment plate abuts against the limiting frame.

[0017] By adopting the technical scheme, the drag bucket is driven to retreat into the shell by the cylinder, and the getter waste abuts against the abutment plate, which abuts against the limiting frame and cannot be rotated downward away from the direction of the vacuum chamber, so that the abutment plate cannot rotate to avoid.

[0018] Further, the shell is connected with a vacuum chamber on one side, the vacuum chamber is connected with a clamp inside, the clamp is connected with a vacuum glass main body inside, and a high-frequency heater is installed on the upper portion of the vacuum chamber.

[0019] By adopting the technical scheme, the worker places the vacuum glass main body in the vacuum chamber and clamps it by the clamp, the vacuum chamber is started to create a vacuum, and the high-frequency heater is started to heat the getter main body, so that the getter main body evaporates and covers the inner wall of the vacuum glass main body to form a film.

[0024] In summary, the present application mainly has the following beneficial effects:

[0025] This invention utilizes a cylinder, a bucket, a sliding plate, a groove, a limiting bracket, a torsion spring shaft, and a stop plate. The getter body, under the influence of gravity, falls onto the bucket. The cylinder then pushes the bucket to move, causing it to enter the vacuum glass body. Simultaneously, the getter body presses against the stop plate, causing the stop plate to rotate downwards along the vacuum chamber direction. This prevents the stop plate from interfering with the movement of the getter body. Furthermore, the bucket moves the sliding plate, which is relatively long and can effectively shield the getter body inside the storage cylinder, preventing it from falling into the outer shell. In the middle section, after the getter evaporates into the vacuum glass body, the cylinder drives the tractor to retract, returning the tractor to the outer shell. At the same time, the getter waste will abut against the stop plate, and the stop plate will abut against the limit frame, preventing it from rotating downward away from the vacuum chamber. Therefore, the stop plate will not rotate to avoid it, but will push the getter waste through the stop plate, causing it to slide out of the tractor and fall into the outer shell. Furthermore, since the width of the groove is greater than the width of the stop plate, it avoids the tractor being unable to retract when the stop plate abuts against it. This facilitates continuous processing and makes it convenient to supply getter to tubular vacuum glass. Attached Figure Description
