The following detailed description of the preferred embodiments of the present application, however, can be practiced otherwise than as specifically described.

To solve the technical problem in the prior art, an embodiment of the present application provides a PIN inserting system, as shown in fig. 1, the PIN inserting system includes:

a workpiece carrier 10 configured to load a workpiece 20;

a PIN inserting device 30 including a holder 31 holding a PIN 40 to be inserted into the workpiece 20; the gripper 31 is movable above the workpiece carrier 10, inserting the PIN 40 into the workpiece 20 by releasing the PIN 40; the number and positions of the PINs 40 on the holder 31 are adapted to the number and positions of the PINs 40 that the workpiece 20 needs to be inserted.

The workpiece 20 may illustratively be a DBC to which PIN PINs 40 are to be inserted, and the workpiece carrier 10 is used to carry and transport the workpiece 20 during production, e.g., moving from one station to another on a production line. For example, during the moving process, the workpiece carrier 10 also serves to temporarily fix the DBC and prevent the DBC from moving relative to the workpiece carrier 10, so that the workpiece carrier 10 has some positioning and temporary fixing structures, which may be some general positioning and fixing structures for the DBC, and will not be described in detail.

Illustratively, the holder 31 is configured to hold the PIN 40 and insert the PIN 40 into the workpiece 20 by releasing the PIN 40. Thus, in addition to holding the PINs 40, the holder 31 also needs to position the PINs 40. Illustratively, the grip and release of the holder 31 are quick to improve production efficiency, but quick grip and release is premised on the inability to cause injury to the PIN 40.

In some embodiments, the holder 31 may include:

a first vacuum chuck 311 configured to suck the PIN 40 by generating a negative pressure to position the PIN 40.

Illustratively, the first vacuum chuck 311 is used for sucking the PIN 40 by generating negative pressure, so that the PIN 40 can be held and released quickly without damaging the PIN 40. For example, the suction force of the first vacuum chuck 311 may be adjusted by adjusting the magnitude of the negative pressure.

In some embodiments, the first vacuum chuck 311 may include a plurality of air pressure control members for controlling a suction air pressure and suction areas corresponding to the air pressure control members, and the plurality of air pressure control members may independently control an air pressure of the corresponding suction areas.

For example, since the number of PIN PINs 40 to be sucked by the first vacuum chuck 311 is relatively large and the number of corresponding workpieces 20 is different, the first vacuum chuck 311 is divided into a plurality of mutually independent suction areas, and each suction area is controlled by an independent air pressure control unit. Thus, the suction of the PIN PINs 40 in each region can be controlled according to the qualification conditions of different workpieces 20 and each region of the same workpiece 20, namely, some regions suck the PIN PINs 40, and some regions do not suck the PIN PINs 40. Alternatively, the release of the PIN 40 may be controlled according to the situation, the PIN 40 in the partial area is released, and the PIN 40 in the partial area is not released. Illustratively, each individual pneumatic control component may be: separate vacuum generators are configured to form separate suction zones. Alternatively, a single vacuum generator may be used, and different adsorption lines and valves may be provided to form separate adsorption regions.

In some embodiments, the holder 31 may further include a second vacuum chuck 312 configured to suck the first vacuum chuck 311 by generating a negative pressure to turn the first vacuum chuck 311 upside down so that the end of the PIN 40 inserted into the workpiece 20 faces downward.

Illustratively, since PIN 40 is loaded into the first vacuum chuck 311, the PIN 40 is generally pointed upward, i.e., the end of PIN 40 that is inserted into the workpiece 20 is pointed upward. When inserting the PIN 40 into the workpiece 20, the PIN 40 is required to be inserted into the workpiece 20 by dropping down the PIN. Therefore, the holder 31 is provided with the second vacuum chuck 312, and the second vacuum chuck 312 sucks the first vacuum chuck 311 by generating negative pressure, so as to turn the first vacuum chuck over. Thus, the structure of the holder 31 is simple, and the vacuum generator for generating negative pressure can be used many times without providing additional other power parts.

In some embodiments, the PIN insertion system may further include:

a workpiece carrier track 50 configured for movement of the workpiece carrier 10 such that the workpiece carrier 10 moves sequentially at each station; the PIN inserting device 30 is disposed on one side of the workpiece carrier rail 50.

Illustratively, the workpiece carrier track 50 is a track for movement of the workpiece carrier 10. The principle of movement of the workpiece carrier 10 on the workpiece carrier track 50 may be sliding friction or rolling friction. The rollers, if rolling friction, may be on the workpiece carrier 10 or on the workpiece carrier track 50. For example, after the workpiece carrier 10 moves to the corresponding station, the workpiece carrier rail 50 is provided with a movable fixing device to fix the workpiece carrier 10, and after the process of the station is completed, the movable fixing device is released, and the workpiece carrier 10 enters the next station. For example, the movement of the workpiece carrier to the corresponding station may be recognized by a travel switch or a position sensor, etc. The PIN inserting device 30 is disposed at one side of the workpiece carrier track 50, and can insert the PINs 40 into the workpieces 20 on the workpiece carrier 10, and the PIN feeding tray 80 can supply the PINs 40 to the PIN inserting device 30.

In some embodiments, the PIN insertion system may further include:

an appearance inspection device 60 configured to inspect the appearance of the workpiece 20; each of the air pressure control means controls the air pressure of the corresponding suction area based on the inspection result of the appearance inspection device 60; the appearance inspection device 60 is arranged on one side of the workpiece carrier track 50 and is arranged at a distance from the PIN insertion device 30; the visual inspection device 60 includes a camera.

Illustratively, the workpiece 20, i.e., the DBC, generally has a plurality of regions and corresponding components, each region corresponding to an absorption region. During incoming material inspection, partial areas are inspected to be unqualified, and the unqualified areas are marked with corresponding unqualified marks (Mark). The appearance inspection device 60 may inspect the unqualified marks, and the air pressure control unit controls the air pressure of the corresponding adsorption area according to the inspection result of the appearance inspection device 60 so that the PIN 40 is adsorbed without generating adsorption force, or the PIN 40 is not released when the PIN is inserted. Therefore, the PIN needle 40 is not inserted into the unqualified area on the DBC, the use of the PIN needle 40 is saved, and the cost is reduced. The visual inspection device 60 is disposed at one side of the workpiece carrier rail 50 and spaced apart from the PIN inserting device 30, and specifically, the visual inspection device 60 performs an inspection process and then performs a PIN inserting process at a station in front of the PIN inserting device 30. In some embodiments, the visual inspection device 60 may employ machine vision, such as by capturing an image of the surface of the workpiece 20 with a camera and then recognizing the image with image recognition software. In particular, since the pattern of the defective mark is set in advance, it is relatively simple, and therefore the image recognition software is easily recognized, and is not easily subjected to errors.

In some embodiments, the PIN insertion system may further include:

a firming agent laying device configured to lay firming agent on the workpiece 20, wherein the laying position of the firming agent is adapted to the position of the PIN 40 which needs to be inserted into the workpiece 20: the curing agent applying device is disposed on one side of the work carrier rail 50 between the visual inspection device 60 and the PIN inserting device 30.

Illustratively, the curing agent is used to cure the PIN 40 to the DBC, and generally needs to be applied to the DBC prior to the PIN 40 being inserted into the PIN 40. Therefore, the curing agent applying device is disposed on one side of the work carrier rail 50 between the visual inspection device 60 and the PIN inserting device 30. In some embodiments, the curing agent may be a solder paste and the curing agent applicator may be a solder paste dispensing device.

In some embodiments, the PIN inserting apparatus 30 may further include:

a driving part configured to drive the movement of the holder 31.

Illustratively, the gripper 31 needs to be moved above the workpiece carrier 10, and thus needs to be driven by a driving means. Moreover, in some embodiments, the holder 31 further needs to turn over the first vacuum chuck 311, and also needs to be driven by a driving unit. In some embodiments, the drive member may be a robotic arm capable of performing multiple motions.

In some embodiments, the PIN insertion system may further include:

a PIN feed tray 80 configured to arrange the PIN PINs 40 and sequentially feed them to the holder 31.

Illustratively, the PIN feed tray 80 is configured to feed the PIN PINs 40 to the holder 31. The PIN feed tray 80 can align the PIN PINs 40 and sequentially feed them to the holder 31. In this way, the PIN 40 can be automatically and continuously fed to the holder 31 by means of the PIN feed tray 80. In some embodiments, the PIN feeding tray 80 may be a vibrating tray, which may automatically arrange the PINs 40 in a row, and sequentially feed the PINs to the holder 31, and the PIN 40 may be replenished after the holder 31 inserts the PINs 40 to the DBC.

In some embodiments, the PIN insertion system may further include:

a heating furnace 90 configured to heat the solidifying agent laid on the workpiece 20 so that the solidifying agent is uniformly laid between the workpiece 20 and the PIN needles 40; the heating furnace 90 is disposed on the workpiece carrier rail 50 and spaced apart from the PIN insertion device 30.

Illustratively, the oven 90 may be a relatively closed oven except for an inlet and an outlet so that the temperature within the oven 90 can be maintained so that the curing agent is continuously heated and uniformly applied between the workpiece 20 and the PIN 40. Illustratively, the heating furnace 90 may be disposed at a station where the PIN PINs 40 are inserted, so that the curing agent is uniformly applied between the workpiece 20 and the PIN PINs 40. Illustratively, the curing agent may be a solder paste that is in a solid or semi-solid state prior to heating and is not uniformly distributed between the workpiece 20 and the PIN 40, and thus requires heating to melt the solder paste into a fluid state.

It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations encompassed by the claims. Various modifications and changes may also be made on the above embodiments without departing from the scope of the present disclosure. Likewise, various features of the above embodiments may be combined in any combination to form additional embodiments of the invention that may not be explicitly described. Therefore, the above embodiments only express several embodiments of the present invention, and do not limit the protection scope of the present invention.
