Description

Technical Field

[0001] The utility model relates to the technical field of cover plate feeding, in particular to a clip-type cover plate feeding device and a seam welding machine. Background Art

[0002] Integrated circuit chips are usually packaged using parallel seam welding machines. After the tube shell and cover plate are aligned, they are fixed to the welding fixture for spot welding and sealing operations. At present, most seam welding machines use clip-type feeding devices to feed the cover plate. Traditional clip-type feeding devices generally use a closed material bin on all sides, and insert a cylinder-type shaping push plate at the upper end to shape the cover plate above the bin to ensure accurate and uniform material collection. This structure has the following problems. First, the application range of the closed material bin on all sides is narrow. Secondly, since the cover plate is very thin, its thickness is generally around 0.1-0.2mm. If the force of the cylinder-type shaping push plate is not properly controlled, it is very easy to damage the cover plate. On the other hand, since the thin cover plates are stacked in the clip bin, it is easy to cause adhesion when the suction cup is used to take the material. Utility Model Content

[0021] See also Figure 1-Figure 3 The present embodiment discloses a clip-type cover plate feeding device, comprising a base plate 1, and a material storage mechanism and a material lifting mechanism connected to the base plate 1. The material storage mechanism is used for storing the cover plates, and the material lifting mechanism is used for lifting the cover plates to facilitate the material taking mechanism to suck or grab them.

[0022] The material storage mechanism includes a material storage bin. In this embodiment, the material storage bin is constructed as two L-shaped baffles arranged diagonally, and the L-shaped baffles have a predetermined height. The rectangular cover plate is stacked up and down and placed in the material storage bin composed of the two L-shaped baffles. For the convenience of distinction, the two L-shaped baffles are defined as a first L-shaped baffle 2 and a second L-shaped baffle 3. In order to make the material storage bin adapt to cover plates of different specifications, the first L-shaped baffle 2 is detachably connected to the bottom plate 1 to facilitate the replacement of different models. Specifically, the top of the bottom plate 1 is fixedly connected to a baffle mounting seat 4 with the same height as the first L-shaped baffle 2, and the baffle mounting seat 4 is provided with an open groove 401 in the height direction. Correspondingly, the rear end of the first L-shaped baffle 2 on this side is provided with a plug-in board 201 that matches the open groove 401. The first L-shaped baffle 2 can be fixed by plugging the plug-in board 201 into the open groove 401.

[0023] The top of the baffle mounting seat 4 is also connected to a fiber optic mounting seat 5 for mounting a fiber optic sensor 6. The fiber optic sensor 6 corresponds to the top position of the first L-shaped baffle 2 and is used to monitor the ejection of the cover plate and determine the timing of removing the cover plate.

[0024] To prevent the cover plate at the discharge end from sticking, in this embodiment, the storage mechanism further includes a pipe joint 7 connected to the upper end of the second L-shaped baffle 3, one end of the pipe joint 7 is connected to the inner side of the second L-shaped baffle 3, and the other end is used to connect to the air source device, and by blowing air on the cover plate at the outlet end, it can prevent them from sticking to each other. The pipe joint 7 can also be connected to the upper end of the first L-shaped baffle 2, and can be set according to actual needs.

[0025] The material lifting mechanism includes a material lifting cover support 8, a support arm 9 for installing the material lifting cover support 8, and a lifting drive member for driving the support arm 9 to perform lifting and lowering movements. The support arm 9 extends into the storage bin from between the two L-shaped baffles, and the cover plates are stacked on the cover support 8. The cover plates are driven upward by the cover support 8 to complete the loading of the cover plates in sequence. In a preferred embodiment, the cover support 8 is also provided with a mounting hole for installing a sensor, and the inventory status of the cover plates in the storage bin is monitored by the sensor.

[0026] The lifting drive member includes a driving motor 10 fixedly connected to the bottom end of the base plate 1 through a motor mounting seat, the output end of the driving motor 10 passes through the base plate 1 and is connected to a ball screw 11, and a guide rail group is also provided at the side end of the ball screw 11, the guide rail group includes a first auxiliary guide rail 13 fixedly connected to the base plate 1 through a guide rail seat 12 and a first slider 14 slidably connected thereto, the top end of the guide rail seat 12 is fixedly connected to a screw mounting seat 15, and the top end of the ball screw 11 is rotatably connected to the screw mounting seat 15. The aforementioned support arm 9 is fixedly connected to the nut end of the ball screw 11, and the side end of the support arm 9 is fixedly connected to the first slider 14, and then the drive motor 10 drives the ball screw 11 to rotate and drive the support arm 9 to lift and lower, and the setting of the guide rail group can ensure the movement accuracy of the support arm 9. In other embodiments, the lifting drive member can also adopt a linear drive structure such as a cylinder and a push rod.

[0027] In practical applications, the cover plates in the storage bin are easily stacked unevenly, which will cause the material taking angle to be non-uniform, and may affect the subsequent alignment accuracy with the tube shell. Therefore, in this embodiment, the second L-shaped baffle 3 is constructed as a movable structure, that is, it can reciprocate in the direction close to or away from the first L-shaped baffle 2. In the process of gradually approaching the cover plate, the second L-shaped baffle 3 can make the cover plate adaptively adjust its position to match the fixed area formed by the first L-shaped baffle 2 and the second L-shaped baffle 3. Specifically, the cover plate feeding device further includes a sliding mechanism for cooperating with the movement of the second L-shaped baffle 3, and the sliding mechanism includes a second auxiliary guide rail 16 fixedly connected to the bottom plate 1 and a second slider 17 slidably connected thereto, and the rear side of the second L-shaped baffle 3 is fixedly connected to the second slider 17 through a baffle seat 18. It should be noted that the setting orientation of the second auxiliary guide rail 16 should be consistent with the diagonal orientation of the two L-shaped baffles to ensure that the two L-shaped baffles can be accurately aligned.

When the cover plate needs to be placed, the second L-shaped baffle 3 can be manually pulled away. After the cover plate is placed, the second L-shaped baffle 3 automatically resets and completes the shaping of the cover plate at the same time. In the present embodiment, the constant force spring 20 can be selected according to the required strength to ensure that the strength is suitable and controllable.
