Detailed Description

In order to more clearly understand the technical features, objects and effects of the embodiments of the present application, specific embodiments of the present application will be described with reference to the accompanying drawings.

Before describing the structure of the test apparatus according to the embodiment of the present application, the structure of the valve 10 to be tested will be briefly described for easy understanding.

As shown in fig. 1 to fig. 3, the tool rack conveying device according to the embodiment of the present application includes a conveying rail 10, an angle adjusting portion, and a lifting portion, where the conveying rail 10 includes a first rail segment 11 and a second rail segment 12 for carrying and conveying the tool rack, and the first rail segment 11 and the second rail segment 12 have different heights. The angle adjustment part is connected with the first track section 11, and the angle adjustment part comprises an installation frame 21 and a rotating mechanism, wherein the rotating mechanism is rotatably arranged on the installation frame 21, and the rotating mechanism drives the tool frame to rotate for setting the angle when the tool frame moves to the rotating mechanism. The lift portion is connected between angle adjustment portion and second track section 12, and when the frock frame removed the lift portion, the lift portion was from first altitude mixture control to the second height with the frock frame to make the height and the first track section 11 of frock frame or the adaptation of second track section 12.

The conveying rail 10 is used for conveying the tool rack, for example, the tool rack loaded with the welded PCB is conveyed to the plug-in station from the main rail through the conveying rail 10, so that the manual handling is reduced. In order to adapt to the height of the main rail and the height of the card insertion station, the conveying rail 10 comprises a first rail section 11 and a second rail section 12, the heights of the first rail section and the second rail section are different, and the lifting part is arranged to lift or lower the tool rack so that the tool rack can be conveyed between the first rail section 11 and the second rail section 12 with different heights. Meanwhile, because the angle of the tool rack conveyed by the main rail is different from the placing angle of the tool rack on the plug-in station, in order to reduce the labor intensity, an angle adjusting part matched with the first rail section 11 is arranged to adjust the angle of the tool rack to be consistent with the angle required by the plug-in station in the process of conveying the tool rack to the plug-in station, so that the worker only needs to take the tool rack off the conveying rail 10 and place the tool rack on the plug-in station when the tool rack is conveyed to the plug-in station, and does not need to leave the plug-in station to convey the tool rack and manually rotate the tool rack by an angle, thereby reducing the labor intensity and improving the efficiency.

The structure and the working process of the tool rack conveying device are described as follows with reference to the attached drawings:

as shown in fig. 1, in order to be able to adapt to the relative position of the main rail and the card insertion station, and to fully utilize the space, in this embodiment, the first rail segment 11 and the second rail segment 12 of the conveying rail are arranged in parallel to each other, and the moving directions of the tool rack on the first rail segment 11 and the second rail segment 12 are opposite, as shown in fig. 1, on the first rail segment 11, the tool rack moves from the right side to the left side, and then on the second rail segment 12, the tool rack moves from the left side to the right side.

Of course, in other embodiments, the relative position relationship between the first track segment 11 and the second track segment 12 may be changed to adapt to different requirements, and the embodiment is not limited thereto.

In order to better accommodate the height of the card insertion station and the main rail, the height of the first rail section 11 is lower than the height of the second rail section 12, so that the first rail section 11 can be used for docking with the main rail and the second rail section 12 is used for conveying the tool rack to the card insertion station, thereby achieving the effect that a worker does not need to bend down to carry the tool rack. It should be noted that, for different requirements, the height difference between the first track segment 11 and the second track segment 12 may also be reversed, that is, the height of the first track segment 11 is higher, which is not limited to this.

As shown in fig. 2, in this embodiment, the first end of the first track segment 11 is an inlet end (i.e. the end where the tool rack enters the first track segment 11), and the second end of the first track segment 11 is an outlet end (i.e. the end where the tool rack goes out of the first track segment 11), that is, the tool rack moves from the first end to the second end on the first track segment 11, so as to save energy and reduce resource waste, the height of the first end of the first track segment 11 is higher than that of the second end, so that the tool rack can move to the second end under the action of its own gravity due to the height difference between the two ends when moving onto the first track segment 11, thereby achieving the effect of omitting or saving a power source.

Optionally, in order to ensure smooth movement of the tool rack and improve the moving efficiency of the tool rack on the first rail segment 11, the first rail segment 11 includes a first bracket 111 and a plurality of rolling members 112 for bearing the tool rack, and the plurality of rolling members 112 are rotatably disposed on the first bracket 111. This supports the tool holder with the rolling members 112 and enables it to move smoothly, reducing friction and wear.

The rolling member 112 may be a roller, a rotatable roller, etc., and the embodiment is not limited thereto.

In this embodiment, the angle adjusting portion is connected with the second end of the first track segment 11 to receive the tooling frame moved out from the first track segment 11, and adjust the angle of the tooling frame, so that the placing angle of the tooling frame meets the requirement of the plug-in station, and the angle can be adjusted manually. Wherein, the installing frame 21 of angle adjustment portion is used for installing rotary mechanism, and rotary mechanism is used for driving the frock frame and rotates to realize angle adjustment's effect.

In one example, the rotation mechanism includes a rotary drive 221 and a rotary structure. The rotary driving member 221 is provided in the mounting frame 21; the rotation structure is rotatably disposed on the mounting frame 21 and used for carrying the tool rack, and the rotation structure is connected to the rotation driving member 221 and is driven by the rotation driving member 221 to rotate by a set angle (which may be determined as required, for example, 30 °, 45 °, 90 °, or 180 °).

In this embodiment, in order to improve stability and reliability and reduce production cost, the rotary driving member 221 may be a pneumatic rotary cylinder disposed on the mounting frame 21.

The rotating table 222a is disposed on the rotating driving member 221, and the rotating track section 222b is disposed on the rotating table 222a, and is driven by the rotating table 222a to rotate to a first position matched with the first track section 11 or to rotate to a second position matched with the lifting portion.

As shown in fig. 2, the rotating track section 222b is connected to a pneumatic rotating cylinder through a rotating table 222a, and is rotated by the pneumatic rotating cylinder. When the rotation angle of the pneumatic rotating cylinder is 0 °, the rotating track section 222b is located at the first position, at this time, the rotating track section 222b corresponds to the first track section 11, the tool rack can be moved to the rotating track section 222b from the second end of the first track section 11, and the rotating track section 222b can guide the tool rack on the one hand and support the tool rack on the other hand.

After it is determined that the tool rack reaches the rotating track section 222b, the pneumatic rotating cylinder may be controlled to drive the rotating track section 222b to rotate 90 ° to the second position, thereby driving the tool rack to rotate 90 °. The rotational track section 222b is oriented in the second position with its transport direction towards the lift, so that the tool rack can be guided onto the lift for height adjustment.

Preferably, in order to ensure the accuracy of the angle adjustment, a first limit stop 241 and a second limit stop 242 are further provided on the mounting frame 21, and the first limit stop 241 is used for limiting the pneumatic rotary cylinder to 0 °, i.e. preventing the pneumatic rotary cylinder from continuing to rotate when it rotates to 0 ° in the first direction (e.g. clockwise). The second limit stop 242 serves to limit the pneumatic rotary cylinder to 90, i.e., prevent it from continuing to rotate when the pneumatic rotary cylinder is rotated to 90 in a second direction (e.g., counterclockwise).

Preferably, in order to enable the tool rest to reliably rotate the rail segment 222b to the elevating portion, the tool rest moves on the rotating rail segment 222b from a first end of the rotating rail segment 222b to a second end of the rotating rail segment 222b, and the first end of the rotating rail segment 222b has a height higher than that of the second end of the rotating rail segment 222 b. In the present embodiment, the structure of the rotating track section 222b is similar to that of the first track section 11, and therefore, the description thereof is omitted.

As shown in fig. 2 and 3, the elevating part includes an elevating frame 31, an elevating driving assembly, and an elevating table 33. The lifting frame 31 is used to carry a lifting drive assembly, a lifting table, and the like. In this embodiment, the lifting frame 31 and the mounting frame 21 are independent frames for easy processing, and in other embodiments, the lifting frame 31 and the mounting frame 21 may be formed as an integral structure, which is not limited.

The lifting driving assembly is arranged on the lifting frame 31, the lifting platform 33 is arranged in the lifting frame 31 and connected with the lifting driving assembly, and the lifting platform 33 is used for bearing the tool rack and adjusting the tool rack to a first height or a second height under the driving of the lifting driving assembly.

Alternatively, in order to improve the compactness and ensure smooth movement of the elevating table 33, the elevating driving assembly includes an elevating motor 321, a lead screw 322 and a nut. Wherein, the lifting motor 321 is disposed on the lifting frame 31; the screw rod 322 is rotatably arranged on the lifting frame 31, and the lifting motor 321 is connected with the screw rod 322 and drives the screw rod 322 to rotate; the nut is sleeved on the lead screw 322 and moves along the lead screw 322 when the lead screw 322 rotates, and the lifting table 33 is connected to the nut and moves under the driving of the nut.

When the lifting platform needs to move up or down, the lifting motor 321 rotates to drive the lead screw 322 to rotate so as to drive the nut to move up and down along the lead screw, thereby realizing the lifting or lowering of the lifting platform 33. The transmission mode of the lead screw 322 and the nut has good stability and can bear larger load.

In this embodiment, in order to enable the tool rack to smoothly move from the lifting table 33 to the second rail section 12, the lifting table 33 is provided with a lifting rail section 34, and when the tool rack is at the second height, the height of the lifting rail section 34 is adapted to the height of the second rail section 12.

The lifting track section 34 may include a chain and a sprocket, the chain being sleeved on the sprocket and the sprocket rotating to drive the chain to move, thereby moving the tool rack on the chain. Of course, the lifting track section 34 may have other structures as long as the tool rack can be driven to move.

The conveying process of the tool rack is described below with reference to fig. 1 as follows:

the first end of the first track section 11 of the frock frame that has welded gets into, because there is the difference in height between the first end of first track section 11 and the second end, and is provided with a plurality of gyro wheels between first end and the second end, consequently under the action of gravity, the frock frame can be followed first track section 11 and moved to the second end to through second end entering angle adjustment portion.

In the angle adjustment section, the tool holder moves onto the rotation rail section 222b of the angle adjustment section. After the tool rack is detected to be in place by the sensor, the rotary drive 221 (e.g., a pneumatic rotary cylinder) is actuated so that the rotary table 222a, the rotary rail section 222b and the tool rack rotate together by 90 °. At this time, the moving direction of the rotation rail section 222b is toward the elevating part, and the tool rack can be automatically moved into the elevating part due to a height difference between the first end and the second end of the rotation rail section 222 b. At this time, the lift table 33 of the lift portion is at a low height position and can receive the tool rack.

After the lifting part detects that the tool rack reaches the lifting platform 33, the lifting motor 321 can be rotated to rotate the lead screw, so that the nut drives the lifting platform 33 and the lifting track segment to rise, and the tool rack reaches the second height. The lifting rail section is then driven to move, and the tool rack is conveyed to the second rail section 12. The second rail section 12 moves to enable the tool rack to move along the second rail section 12, and when the tool rack passes through the plug-in station, the tool rack can be manually taken down from the second rail section 12 and placed at the plug-in station. Therefore, the manual operation of leaving the plug-in unit station to carry the tool frame is not needed, and the tool frame is not needed to be manually rotated by 90 degrees, so that the labor intensity is reduced, and the production efficiency is improved.
