Description

Technical Field

[0001] This utility model relates to the field of workpiece conveying technology, and in particular to a workpiece conveying guide structure for general-purpose external inspection equipment. Background Technology

[0002] In automated production and quality inspection processes, external inspection equipment requires that the workpieces being inspected pass through the inspection station one by one, at equal intervals, and stably to ensure the accuracy and efficiency of the inspection. In upstream processes, workpieces are batched or stacked in a disorderly manner. Existing workpiece conveying and guiding structures, with simple conveyor belts and fixed guardrails on both sides, result in workpieces being arranged side by side, piled up, or closely connected one after another when faced with disordered incoming materials. This uneven incoming material state seriously interferes with the normal operation of external inspection equipment, leading to missed inspections or false inspections, and reducing the automation level of the production line.

[0003] To accommodate different batches and sizes of workpieces, production lines need to frequently change products. Many existing conveyor and guide structures are designed for specific workpiece sizes, and the width of their guide channels is fixed or difficult to adjust. When it is necessary to switch workpieces, operators must spend a lot of time making mechanical adjustments or even replacing the entire guide device. This results in poor equipment versatility and low production changeover efficiency.

[0004] Therefore, this utility model proposes a workpiece conveying and guiding structure for general-purpose external inspection equipment to address the shortcomings of existing technologies. Summary of the Invention

[0005] In view of the problems of workpiece conveying and guiding structures in general-purpose external inspection equipment in the prior art, such as workpiece accumulation and uneven spacing during conveying, and the fixed width of the guide channel which cannot adapt to workpieces of different sizes and specifications, resulting in poor versatility, this utility model aims to provide a workpiece conveying and guiding structure for general-purpose external inspection equipment with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a workpiece conveying and guiding structure for general-purpose external inspection equipment, including: a first conveyor belt and a protective edge arranged along the side of the first conveyor belt. The structure also includes a second conveyor belt, the starting end of which is adjacent to the ending end of the first conveyor belt, and a guide plate, which is arranged above the first and second conveyor belts along the workpiece conveying direction.

[0007] The present invention also includes a limiting mechanism for adjusting the spacing between the guide plates. The limiting mechanism includes a second support plate fixed to the edge and a second fixed shaft vertically fixed to the second support plate. A ring is slidably sleeved on the second fixed shaft. The ring is fixedly connected to the guide plate. The limiting mechanism also includes a turntable rotatably connected to the second support plate. A spiral plate is fixedly connected to the bottom of the turntable. The spiral plate is drivenly connected to the ring and is used to drive the ring to move axially along the second fixed shaft.

[0008] Furthermore, this utility model also includes a spacing mechanism disposed downstream of the guide plate. The spacing mechanism includes a first support plate fixed to the guard edge and a partition assembly disposed on the first support plate. The partition assembly includes a motor and a multi-slot blade driven to rotate by the motor. A fence is fixed to a portion of the outer periphery of the multi-slot blade.

[0009] Preferably, the spacing mechanism further includes a support column, a first fixed shaft, and a height limiting plate. The support column is vertically connected to the guard edge, and the height limiting plate is detachably fixed to the support column via the first fixed shaft and is located upstream of the feed end of the guide plate, spanning the first conveyor belt.

[0010] Preferably, in order to realize the lifting adjustment and locking of the support column, a groove is provided on the guard edge for the lifting of the support column, and the equalization mechanism also includes a threaded handle, which passes through the support column and is threadedly connected to the threaded hole on the guard edge for locking and fixing the support column.

[0012] Preferably, in order to achieve precise driving of the ring by the spiral plate, the upper end face of the ring is provided with a protrusion structure, and the bottom surface of the spiral plate is provided with a spiral groove that meshes with the protrusion structure. The ring moves axially along the second fixed axis as the spiral plate rotates through the meshing of the protrusion structure and the spiral groove.

[0013] Preferably, to prevent the turntable from rotating unexpectedly after adjustment, the limiting mechanism further includes a damping pad, which is disposed between the contact surfaces of the turntable and the second support plate to apply a damping force to the rotation of the turntable, thereby achieving position locking.

[0014] Preferably, to achieve synchronous adjustment of the guide width, there are two guide plates arranged parallel to each other along the workpiece conveying direction, and there are also two rings. The two rings are respectively fixedly connected to the guide plates, and the spiral groove of the spiral plate is designed to drive the two rings to move synchronously towards or away from each other.

[0015] Preferably, to ensure that the workpiece can be accurately fed into the separating assembly, the discharge end of the guide plate extends to the feed side of the separating assembly, for gathering the workpiece and guiding it into the groove of the multi-groove blade.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a general-purpose external inspection equipment workpiece conveying and guiding structure, which aims to solve the problems of workpiece accumulation, uneven spacing and inability to adapt to workpieces of different sizes in the prior art, resulting in poor versatility.

[0023] like Figure 1 and Figure 2 As shown, the general-purpose external inspection equipment workpiece conveying and guiding structure includes a first conveyor belt 1 and a guard edge 2 arranged along the side of the first conveyor belt 1. The first conveyor belt 1 is used for basic workpiece conveying, and the guard edge 2 is used for initial workpiece positioning and as the mounting base for other components. The structure also includes a second conveyor belt 3, with the conveying start end of the second conveyor belt 3 adjacent to the conveying end end of the first conveyor belt 1. A guide plate 6 is provided, which is arranged above the first conveyor belt 1 and the second conveyor belt 3 along the workpiece conveying direction to guide the workpiece conveying path. To adjust the spacing of the guide plates 6 to accommodate workpieces of different sizes, a limiting mechanism 5 is provided. To achieve equidistant separation of workpieces, a balancing mechanism 4 is provided downstream of the guide plates 6.

[0024] Please refer to Figure 1 , Figure 2 and Figure 4The limiting mechanism 5 includes a second support plate 501 fixed to the edge guard 2, and a second fixed shaft 502 vertically fixed on the second support plate 501; a ring 503 is slidably sleeved on the second fixed shaft 502, and the ring 503 is fixedly connected to the guide plate 6; the limiting mechanism 5 also includes a turntable 504 rotatably connected to the second support plate 501, and a spiral plate 506 is fixedly connected to the bottom of the turntable 504; the spiral plate 506 and the ring 503 form a transmission connection, which is used to drive the ring 503 to move axially along the second fixed shaft 502 when the turntable 504 rotates.

[0025] Specifically, refer to Figure 4 The upper surface of the ring 503 is provided with a protruding structure, while the bottom surface of the spiral plate 506 is provided with a spiral groove that meshes with the protruding structure. When the operator rotates the turntable 504, the spiral plate 506 rotates synchronously. The spiral groove on it drives the ring 503 to translate along the axial direction of the second fixed shaft 502 through the meshing transmission with the protruding structure, thereby driving the guide plate 6 fixed thereto to move. In a specific embodiment, there are two guide plates 6, which are arranged parallel to each other along the workpiece conveying direction. There are also two rings 503, which are fixedly connected to the guide plates 6 respectively. The spiral groove on the spiral plate 506 can drive the two rings 503 to move synchronously towards or away from each other, thereby realizing the precise adjustment of the distance between the two guide plates 6. In order to prevent the adjusted position from shifting due to vibration, the limiting mechanism 5 also includes a damping pad 505. The damping pad 505 is disposed between the contact surfaces of the turntable 504 and the second support plate 501, and is used to apply damping force to the rotation of the turntable 504, so as to play a role in locking and stabilizing.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 3 To limit the height of the stacked workpieces, the equalization mechanism 4 also includes a support column 402, a first fixed shaft 403, a first support plate 407, and a height limiting plate 404. The support column 402 is vertically connected to the guard edge 2, and the height limiting plate 404 is detachably fixed to the support column 402 via the first fixed shaft 403 and is located upstream of the feed end of the guide plate 6, spanning the first conveyor belt 1. More specifically, the guard edge 2 has a groove 401 for the support column 402 to be raised and lowered. The equalization mechanism 4 also includes a threaded handle 405, which passes through the support column 402 and is threadedly connected to the threaded hole on the guard edge 2 to lock and fix the support column 402.

[0027] In another preferred embodiment, in order to achieve a smooth transition between the first conveyor belt 1 and the second conveyor belt 3 and to help widen the workpiece spacing, the equalization mechanism 4 also includes a roller 406; the roller 406 is rotatably connected between the frame of the first conveyor belt 1 and the frame of the second conveyor belt 3, and is located between the conveying end of the first conveyor belt 1 and the conveying start end of the second conveyor belt 3.

[0028] As another preferred embodiment, in order to ensure that the workpiece is accurately guided to the separator 408, the discharge end of the guide plate 6 extends to the feed side of the separator 408 to gather the workpiece and guide it into the groove of the multi-groove blade 4082.

[0029] Working principle: The height of stacked workpieces from external inspection equipment is limited by the height-limiting plate 404 fixed in the equalizing mechanism 4 to prevent workpiece accumulation. The height-limiting plate 404 is fixed to the support column 402 via the first fixed shaft 403. The height-limiting plate 404 does not rotate when fixed and can be replaced. The support column 402 can be raised and lowered within the groove 401. The threaded handle 405 is fixed to the support column 402 by threaded connection with the threaded groove on the guard edge 2, so as to adjust the height limit according to different workpieces to prevent accumulation. Then, the workpieces conveyed by the first conveyor belt 1 arrive at the roller 406 and are separated. On the roller 406, the front... The workpiece moves forward rapidly under the drive of the second conveyor belt 3, and is separated from the workpiece behind the roller 406 to prevent the workpiece from accumulating. The workpiece is guided by the guide plate 6 and comes to the vicinity of the first support plate 407. The motor 4081 on the first support plate 407 starts and drives the multi-slot blade 4082 to rotate to receive the separated workpiece. After being driven by the rotation of the multi-slot blade 4082, the workpiece is carried out along the fence 4083. The fence 4083 in the separating component 408 is used to prevent the workpiece from being thrown out and hitting the guard edge 2, so as to achieve equal and even distribution of the workpiece, avoid workpiece accumulation, and increase workpiece detection efficiency. Furthermore, the turntable 504 is fixed on the edge guard 2 by the second support plate 501. When the handle on the turntable 504 in the rotation limiting mechanism 5 is rotated, the spiral plate 506 at the bottom of the turntable 504 also rotates. The convex structure above the ring 503 is embedded in the spiral plate 506. The two rings 503 sleeved on the second fixed shaft 502 will move along the axial direction of the second fixed shaft 502. After adjustment, the damping pad 505 blocks the turntable 504 from continuing to rotate. At the same time, the ring 503 fixes the guide plate 6. Adjusting the distance between the two rings 503 is to adjust the distance between the two guide plates 6, so as to adjust the distance between the guide plates 6 according to different workpieces to adapt to different workpiece sizes for guiding.
