When producing a KBL rectifier bridge with this structure, a positioning plate is usually required to position and assemble the pins, and then the positioning plate and the pins are placed in a sintering furnace for sintering and curing. The pin assembly formed after curing needs to be packaged using packaging equipment to form a complete packaged device. Figure 5 As shown, before packaging, the inner end of the pin assembly, that is, the pin end, needs to be set in an aluminum row 6, and the outer end of the pin assembly, that is, the end that needs to be packaged, needs to be exposed on the outside of the aluminum row 6. The aluminum row 6 with the pin assembly installed is then placed in the aluminum row seat 83 on the transfer rack 8. Finally, the transfer rack 8 is sent into the packaging equipment to batch package the pin assemblies.

Such an operation process requires manual work to place the aluminum bar and adjust the pin position, has a high dependence on workers, has a low degree of automation, and has a high time cost, and is not suitable for mass production of packaged devices.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0029] The present application embodiment provides a pin assembly transfer device, such as Figure 1As shown, it is used to automatically and effectively place the aluminum row 6 with the pin assembly 7 installed on the aluminum row seat 83 in the transfer frame 8, and adjust the position of the pin assembly 7 during the placement process, including: a first linear mechanism 1, a second linear mechanism 2, a lifting cylinder 3, etc. The first linear mechanism 1 is set on the base 9. Specifically, the base 9 is provided with four columns 91 for supporting the first linear mechanism 1; the second linear mechanism 2 is arranged at the moving end of the first linear mechanism 1, and the lifting cylinder 3 is arranged at the moving end of the second linear mechanism 2. The movable end of the lifting cylinder 3 is connected to the third linear mechanism 4, wherein the travel direction of the first linear mechanism 1 and the travel direction of the second linear mechanism 2 are both located in the horizontal plane and are perpendicular to each other, and the travel direction of the first linear mechanism 1 is parallel to the travel direction of the third linear mechanism 4; as shown Figure 2 As shown, a moving plate 41 is provided at the moving end of the third linear mechanism 4, one end of the shell of the third linear mechanism 4 is rotatably connected to the upper end of a rotating arm 52 through a first rotating shaft 42, the moving plate 41 is rotatably connected to one end of a rotating rod 51 through a second rotating shaft 43, and the other end of the rotating rod 51 is rotatably connected to the lower part of the rotating arm 52 through a third rotating shaft 44; the first rotating shaft 42, the second rotating shaft 43 and the third rotating shaft 44 are parallel to each other and perpendicular to the second linear mechanism 2; the lower end of the rotating arm 52 is connected to a clamping mechanism 5 for clamping the aluminum row 6.

[0030] Specifically, as an optional implementation form of the clamping mechanism 5, Figure 2 As shown, it includes a clamping frame 56 arranged along the stroke direction of the first linear mechanism 1, with through holes on both sides of the clamping frame 56, and a two-way cylinder 57 is arranged inside the clamping frame 56. The movable ends of the two-way cylinder 57 pass through the through holes on both sides of the clamping frame 56 and are vertically connected with a clamping plate 58, which is used to clamp the aluminum bar.

[0031] When the clamping plate 58 clamps the aluminum row 6 with the pin assembly 7 installed under the action of the bidirectional cylinder 57, the lifting cylinder 3 drives the clamping mechanism 5 to move upward. At the same time, the active end of the first linear mechanism 1 is connected to the second linear mechanism 2, and the active end of the second linear mechanism 2 is connected to the lifting cylinder 3, so that the clamping mechanism 5 can simultaneously achieve lifting and moving along the first linear mechanism 1 and along the second linear mechanism 2, ensuring that the device can place the aluminum row into each aluminum row seat 83. Figure 2 As shown, one end of the shell of the third linear mechanism 4 is connected to the upper end of the rotating arm through the first rotating shaft, a first rotating seat 53 is provided on the lower surface of the moving plate 41, a second rotating seat 54 is provided on the lower surface of the rotating arm 52 close to the third linear mechanism 4, and the second rotating shaft 43 and the third rotating shaft 44 are provided at both ends of the rotating rod 51, respectively, the second rotating shaft 43 is matched with the first rotating seat 53, and the third rotating shaft 44 is matched with the second rotating seat 54; Figure 3As shown, the clamping plate 58 clamps the aluminum row 6, and after reaching a certain height under the action of the lifting cylinder 3, the moving end of the third linear mechanism 4 drives the moving plate 41 to move. Since the third linear mechanism 4, the rotating arm 52, and the rotating rod 51 are all movably connected, the moving plate will use the rotating rod 51 to push or pull the rotating arm 52, and under the action of the first rotating shaft 42, the clamping mechanism 5 can realize the movement of rotating around the first rotating shaft 42; the clamping mechanism 5 stops rotating after being rotated to a certain angle, and the pins at the inner ends of the pin assembly 7 are held down due to their own gravity. The rotating arm 52 automatically and completely enters the hole for placing the pin assembly 7 set in the aluminum row 6, thereby adjusting the installation position of the pin assembly 7 on the aluminum row 6 and ensuring that the pin assembly 7 will not fall out of the aluminum row 6 during the clamping process; after the position adjustment of the pin assembly 6 is completed, the rotating arm 52 will restore the vertical state to place the aluminum row 6 on the aluminum row seat 83; the base 9 is provided with two limit blocks 92 adapted to the structure of the transfer frame 8 to ensure that the position of the transfer frame 8 relative to the base 9 does not change, thereby avoiding affecting the placement effect, such as Figure 1 shown.

[0032] More specifically, when the rotating arm 52 is in a vertical state, the moving plate 41 is located in the middle position of the stroke of the third linear mechanism 4, such as Figure 2 When the outer end of the pin assembly 7 in the aluminum row 6 clamped by the clamp 58 is facing the opposite direction of the handle on the transfer rack 8, as Figure 3 and Figure 1 As shown, the movable plate 41 moves in the direction away from the rotating arm 52, thereby pulling the rotating arm 52 through the rotating rod 51, so that the rotating arm 52 rotates around the first rotating axis 42 to form a certain acute angle with the third linear mechanism 4; when the outer end of the pin assembly 7 in the aluminum row 6 clamped by the clamping plate 58 is toward the handle on the transfer frame 8, the movable plate 41 moves in the direction close to the rotating arm 52, thereby pushing the rotating arm 52 through the rotating rod 51, so that the rotating arm 52 rotates around the first rotating axis 42 to form a certain obtuse angle with the third linear mechanism 4.

[0033] Specifically, in order to ensure that the relative position of the aluminum bar 6 and the clamping plate 58 remains unchanged when placing the aluminum bar 6 and adjusting the position of the pin assembly 7, a rectangular positioning pin 59 is provided on the lower surface of the clamping plate 58 for contacting the aluminum bar 6, and rectangular positioning holes 61 adapted to the rectangular positioning pin 59 are provided on both sides of the aluminum bar 6 in contact with the clamping plate 58. Figure 4 As shown, under the action of the positioning pin 59 and the positioning hole 61 , the aluminum bar 6 cannot rotate or move relative to the position of the clamping plate 58 .

[0034] Specifically, each aluminum row seat 83 is provided with an escape groove 81 along the length direction of the aluminum row 6 near the frame of the transfer rack 8. Figure 5As shown, the clamping mechanism 5 moves downward until the clamping plate 58 contacts the bottom surface of the aluminum row seat 83, and the two-way cylinder 57 operates to drive the clamping plate 58 to move in the avoidance groove 81, thereby placing the aluminum row 6 on the aluminum row seat 83.

[0035] Specifically, Figure 5 As shown, each aluminum row seat 83 is provided with four positioning blocks 82 along the length direction of the aluminum row 6; Figure 4 As shown, four positioning grooves 62 adapted to the positioning blocks 82 are arranged on the bottom surface of each aluminum row 6 along its length direction. The arrangement of the positioning blocks 82 and the positioning grooves 62 enables the aluminum row 6 to be accurately positioned at the placement position on the aluminum row seat 83.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
