Description

Technical Field

[0001] This utility model relates to the field of electronic product processing technology, and in particular to an automatic screening and sorting device for electronic components. Background Technology

[0002] The automatic electronic component sorting and sorting device, also known as an automatic array machine, contains a drive mechanism that can drive the worktable to reciprocate. The worktable is usually equipped with two or more array frames, which contain clamps and grooves. The screen plate is placed in the groove and sealed and limited by the clamps. Multiple electronic components at one end of the frame are filled into the screen holes of the screen plate by the reciprocating motion mechanism, thus completing the sorting and sorting work.

[0003] In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: the size of the groove is generally smaller than the size of the frame, and the frame is generally a rectangular groove. During the movement, it moves from one end to the other. Due to the size mismatch, the electronic components, especially some small electronic components, move from the outside of the screen plate to the inner side wall of the frame. When the electronic components cannot enter the screen plate area, it will cause some screen holes to not be filled with electronic components more quickly, which will increase the movement time of the motion mechanism and affect the overall work efficiency. Utility Model Content

[0004] The main objective of this invention is to provide an automatic screening and sorting device for electronic components, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic screening and sorting device for electronic components includes a mold base with a groove carved into one end. An adjustable sealing plate is provided at the end of the mold base near the groove. Guide mechanisms are provided on both sides of the mold base at the end of the groove away from the adjustable sealing plate. Each guide mechanism includes a screw, with side plates rotatably connected to both ends of the screw. Internal threaded cylinders are threaded to the outer walls of both ends of the screw. An outer block is fixed to one end of each internal threaded cylinder. A traction rod is fixed to the top of each outer block. A guide plate is rotatably connected to the end of each traction rod away from the outer block. Connecting rubber is adhered to the adjacent ends of the guide plates. Movable seats are fixed to the adjacent inner side walls of the guide plates. Pull rods are movably connected between the movable seats. A positioning tube is provided between the pull rods. A spring telescopic rod is fixed to the outer wall of the positioning tube, and a tension spring is embedded inside the positioning tube.

[0007] Preferably, the side plates are fixed to the outer side wall of the mold base.

[0008] Preferably, the outer blocks are in contact with the outer wall of the mold base.

[0009] Preferably, the screw is fixed with a screw cap at the middle position between the internal threaded cylinders.

[0010] Preferably, the end of the spring telescopic rod away from the positioning tube is fixed to the inner wall of the mold base, and the ends of the pull rods close to each other are respectively inserted into the interior of the positioning tube and fixed to the end close to the tension spring. The pull rods are slidably connected to the positioning tube.

[0011] Preferably, the end of the guide plate away from the connecting rubber and the inner wall of the mold base is a slope, and the ends of the guide plates that are far apart from each other are in contact with the inner wall of the mold base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting a guide mechanism in the inner plate groove of the mold base away from the adjustable sealing plate, the electronic components can be precisely guided during the movement, so that when the electronic components enter the plate groove area, they can make fuller contact with the screen plate, avoiding the problem of insufficient screening and prolonged working time caused by some electronic components moving along the inner edge of the mold base.

[0014] 2. The guide mechanism can adjust its guiding angle, so that when the screen holes of some screen plates are more centered, the screening work can be completed more quickly. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, an automatic screening and sorting device for electronic components includes a mold base 1. A groove 2 is carved into one end of the mold base 1. An adjustable sealing plate 3 is provided at the end of the mold base 1 near the groove 2. Guide mechanisms 4 are provided on both sides of the mold base 1 at the end of the groove 2 away from the adjustable sealing plate 3. Each guide mechanism 4 includes a screw 41. Side plates 42 are rotatably connected to both ends of the screw 41. Internal threaded cylinders 43 are threadedly connected to the outer walls of both ends of the screw 41. An outer block 4 is fixed to one end of each internal threaded cylinder 43. 4. Each outer block 44 has a traction rod 47 fixed to its top. The end of the traction rod 47 away from the outer block 44 is rotatably connected to a guide plate 45. The end of the guide plate 45 that is close to each other is bonded with a connecting rubber 46. Each inner sidewall of the guide plate 45 that is close to each other is fixed with a movable seat 48. Each movable seat 48 is movably connected with a pull rod 49. A positioning tube 410 is provided between the pull rods 49. A spring telescopic rod 411 is fixed to the outer wall of the positioning tube 410. A tension spring is embedded inside the positioning tube 410.

[0022] Specifically, the side plates 42 are fixed to the outer side wall of the mold base 1.

[0023] Specifically, the outer blocks 44 contact the outer wall of the mold base 1, so that the rotation of the screw 41 can drive the inner threaded cylinder 43 to move.

[0024] Specifically, a screw cap 412 is fixed at the middle position between the screw 41 and the internal threaded cylinder 43 to facilitate the rotation of the screw 41.

[0025] Specifically, the end of the spring telescopic rod 411 away from the positioning tube 410 is fixed to the inner wall of the mold base 1, and the ends of the pull rods 49 close to each other are respectively inserted into the interior of the positioning tube 410 and fixed to the end close to the tension spring. The pull rods 49 are slidably connected to the positioning tube 410, which can play a limiting telescopic pulling role when adjusting the included angle between the two guide plates 45.

[0026] Specifically, the end of the guide plate 45 that is away from the connecting rubber 46 and the inner wall of the mold base 1 is a slope, and the ends of the guide plate 45 that are away from each other are in contact with the inner wall of the mold base 1 to avoid obstructing the travel path of the electronic components.

[0027] Working principle:

[0028] By providing a guide mechanism 4 at a position in the inner plate groove 2 of the mold base 1 away from the adjustable sealing plate 3, the electronic components can be precisely guided during movement, so that when the electronic components enter the plate groove 2 area, they can make fuller contact with the screen plate, avoiding the problem of insufficient screening and prolonged working time caused by some electronic components moving along the inner edge of the mold base 1. The guide mechanism 4 can adjust its guiding angle, so that when the screen holes of some screen plates are more centered, the screening work can be completed faster.

[0029] Adjustment steps:

[0030] The screw 41 is rotated by the rotation of the screw cap 412. The inner threaded cylinder 43 contacts the mold base 1 through the outer block 44, so that the screw 41 can drive the traction rod 47 to move closer or further apart after rotation. The traction rod 47 can drive the guide plate 45 to move. The spring telescopic rod 411, the positioning tube 410, the tension spring in the positioning tube 410, the pull rod 49 and the combination of the pull rod 49 can form a telescopic limit in the middle of the guide plate 45. One end of the guide plate 45 is pulled by the traction rod 47, and the middle end is restricted by telescopic movement, so that the included angle between the guide plates 45 can be adjusted and move against the inner side wall of the mold base 1. The connecting rubber 46 between the two guide plates 45 plays the role of bending at the middle point without obstructing the path of electronic components.
