[0060] Embodiment 1

[0061] In the prior art, the inspection station 22 is arranged on the assembly line, and the inspection mechanism 3 performs image acquisition when the workpiece to be inspected is transported to the inspection station 22. However, when inspecting some workpieces that are not suitable for belt conveying, a transport and clamping device is required to transport the workpieces to the inspection station respectively, and then inspect them after clamping.

[0062] The existing conveying mechanism 4 and clamping mechanism 5 are driven by different driving mechanisms respectively, and after the conveying mechanism 4 releases the workpiece and withdraws from the detection station 22, the clamping mechanism 5 enters the detection station 22 and then clamps the workpiece. Although it can avoid the conveying mechanism 4 and the clamping mechanism 5 from interfering with each other, more actions are performed, which increases the operation time for preparing for detection and reduces the detection efficiency.

[0063] In order to solve the above problems, Figures 1 to 5 As shown, this embodiment provides a transporting and clamping device, which can transfer the workpiece to be inspected located upstream of the inspection station 22 of the assembly line to the inspection station 22, and can clamp the workpiece located on the inspection station 22. The transporting and clamping device includes a frame 1, and the assembly line is arranged on the frame 1. The assembly line includes an upstream station 21, an inspection station 22 and a downstream station 23. The transporting and clamping device also includes a detection mechanism 3, a transport mechanism 4, a clamping mechanism 5 and a linkage mechanism arranged on the frame 1. The transport mechanism 4 can move into / out of the inspection station 22 in a direction perpendicular to the conveying direction of the assembly line, so as to transfer the workpiece located on the upstream station 21 to the inspection station 22. The clamping mechanism 5 can move into / out of the inspection station 22, and can clamp the workpiece located on the inspection station 22. The linkage mechanism is respectively connected to the transport mechanism 4 and the clamping mechanism 5, so that when one of them moves into the inspection station 22, the other moves out of the inspection station 22.

[0064] By setting up a linkage mechanism, when one of the transport mechanism 4 and the clamping mechanism 5 moves into the inspection station 22, the other moves out of the inspection station 22. While avoiding interference between the transport mechanism 4 and the clamping mechanism 5, the execution actions are reduced, the operation time for preparing for inspection is shortened, the inspection efficiency is improved, and the equipment cost is reduced.

[0065] Preferably, in this embodiment, the conveying mechanism 4 and the clamping mechanism 5 are arranged at a relative interval, and both can be moved into / out of the detection station 22 in a direction perpendicular to the conveying direction of the assembly line. The detection station 22 is arranged between the conveying mechanism 4 and the clamping mechanism 5, and the linkage mechanism includes a connecting member 61 and a driving member 413, wherein the driving member 413 is a first cylinder, and the two ends of the connecting member 61 are respectively connected to the conveying mechanism 4 and the clamping mechanism 5, the first cylinder is arranged on the frame 1, and the piston of the first cylinder is connected to the conveying mechanism 4 and extends in a direction perpendicular to the conveying direction of the assembly line, so that when the conveying mechanism 4 is driven to move into the detection station 22, the connecting member 61 drives the clamping mechanism 5 to move out of the detection station 22; and when the conveying mechanism 4 is driven to move out of the detection station 22, the connecting member 61 drives the clamping mechanism 5 to move into the detection station 22.

[0066] Specifically, in this embodiment, the transport mechanism 4 includes a first moving assembly 41 , a first substrate 42 , a second moving assembly 43 , a second substrate 44 , a third moving assembly 45 , a first connecting plate 46 , a first adsorption assembly 471 and a second adsorption assembly 472 .

[0067] The first moving assembly 41 includes a pair of first slide rails 411, a pair of first sliders 412 and a first cylinder. The pair of first slide rails 411 are spaced apart on the frame 1 and extend in a direction perpendicular to the conveying direction of the assembly line. The pair of first sliders 412 are slidably connected to the pair of first slide rails 411 respectively. The first base plate 42 is connected to the pair of first sliders 412. The piston of the first cylinder is connected to the first base plate 42 to drive the first base plate 42 to move in a direction perpendicular to the conveying direction of the assembly line.

[0068] The second moving component 43 is arranged on the first substrate 42, and the second moving component 43 includes a second slide rail 431, a pair of second sliders 432 and a second cylinder 433. The second slide rail 431 extends along the conveying direction of the assembly line. The pair of second sliders 432 are slidably connected to the second slide rail 431 and are spaced apart. The second substrate 44 is connected to the pair of second sliders 432. The piston of the second cylinder 433 is connected to the second substrate 44 and extends along the conveying direction of the assembly line to drive the second substrate 44 to move along the conveying direction of the assembly line, so that the second moving component 43 will not affect the movement of the clamping mechanism 5 during the movement, and the structure of the conveying mechanism 4 is more stable.

[0069] The third moving assembly 45 is disposed on the second substrate 44, and the third moving assembly 45 includes a guide member 451 and a third cylinder 452. The third cylinder 452 is disposed on the second substrate 44, and the first connecting plate 46 is connected to the piston of the third cylinder 452. The piston of the third cylinder 452 extends in the vertical direction to drive the first connecting plate 46 to rise and fall.

[0070] The length of the first connecting plate 46 is not less than the distance between the first adsorption component 471 and the second adsorption component 472. The first adsorption component 471 and the second adsorption component 472 are arranged on the first connecting plate 46 at intervals along the conveying direction of the assembly line, and the distance between the upstream station 21 of the detection station 22 and the detection station 22, the distance between the detection station 22 and the downstream station 23 of the detection station 22, and the distance between the first adsorption component 471 and the second adsorption component 472 are the same, so that when the first adsorption component 471 absorbs the workpiece located at the upstream station 21, the second adsorption component 472 can absorb the workpiece located at the detection station 22, and in the conveying operation of the conveying mechanism 4, the workpiece located at the upstream station 21 and the workpiece located at the detection station 22 can be simultaneously conveyed to the detection station 22 and the downstream station 23 respectively, which not only reduces the conveying steps and improves the conveying efficiency, but also reduces the equipment cost.

[0071] A pair of travel switches 48 are provided on the first substrate 42, and the pair of travel switches 48 are arranged at intervals. The pair of travel switches 48 are electrically connected to the second cylinder 433, and the pair of travel switches 48 can limit the first adsorption component 471 of the conveying mechanism 4 to move to the upstream station 21 and the detection station 22 respectively, so as to limit the moving end of the second moving component 43 to move between the pair of travel switches 48.

[0072] With the above structure, in order to enhance the load-bearing capacity of the conveying mechanism 4, the piston of the third cylinder 452 is connected to the midpoint of the first connecting plate 46, and the guide member 451 includes a vertically arranged guide column and a ball bushing, a pair of ball bushings are respectively arranged at both ends of the second base plate 44, a pair of guide columns are respectively arranged at both ends of the first connecting plate 46, and a pair of guide columns are respectively slidably connected to a pair of ball bushings to guide the first connecting plate 46 to rise and fall vertically, which not only enhances the load-bearing capacity of the conveying mechanism 4, but also prevents the first adsorption component 471 and the second adsorption component 472 from tilting when moving the adsorbed workpiece.

[0073] The clamping mechanism 5 includes a pair of third slide rails 51, a pair of third sliders 52, a fourth cylinder 53, a pressure head 54 and a second connecting plate 56. The pair of third slide rails 51 are arranged at intervals and extend in a direction perpendicular to the conveying direction of the assembly line. The pair of third sliders 52 are slidably connected to the pair of third slide rails 51, respectively. The fourth cylinder 53 is arranged on the pair of third sliders 52. The connecting member 61 is connected to the pair of third sliders 52 to drive the pair of third sliders 52 to slide. The second connecting plate 56 is connected to the piston of the fourth cylinder 53, and the piston of the fourth cylinder 53 extends in the vertical direction to be able to drive the second connecting plate 56 to rise and fall. The pressure head 54 is arranged on the second connecting plate 56 to be able to press the workpiece when the second connecting plate 56 rises and falls.

[0074] Furthermore, in order to prevent the pressure head 54 from damaging the workpiece due to excessive downward pressure when pressing the workpiece, in the present embodiment, the clamping mechanism 5 also includes a second elastic member 55, which can be elastically deformed in the vertical direction to compress the second elastic member 55 when the pressure head 54 presses the workpiece located at the detection station 22, and the compressed second elastic member 55 can cause the pressure head 54 to move together to reduce the pressure of the pressure head 54 on the workpiece, thereby avoiding damage to the workpiece.

[0075] This embodiment also provides a detection method based on the above-mentioned handling and clamping device, and the detection method includes:

[0076] Drive the moving end of the second moving component 43 to move, so that the first adsorption component 471 moves to the upstream station 21;

[0077] After driving the clamping mechanism 5 to release the workpiece at the detection station 22, the moving end of the first moving component 41 is driven to move, so that the first adsorption component 471 and the second adsorption component 472 are moved into the upstream station 21 and the detection station 22 respectively, and the linkage mechanism drives the clamping mechanism 5 to move out of the detection station 22;

[0078] After the first adsorption component 471 and the second adsorption component 472 respectively absorb the workpieces located at the upstream station 21 and the detection station 22, the moving end of the second moving component 43 is driven to move, so that the first adsorption component 471 and the second adsorption component 472 are moved to the detection station 22 and the downstream station 23 respectively;

[0079] After the first adsorption component 471 and the second adsorption component 472 release their respective adsorption workpieces, the moving end of the first moving component 41 is driven to move, so that the first adsorption component 471 and the second adsorption component 472 are moved out of the detection station 22 and the downstream station 23 respectively, and the linkage mechanism drives the clamping mechanism 5 to move into the detection station 22;

[0080] After the clamping mechanism 5 clamps the workpiece on the inspection station 22, the inspection mechanism 3 inspects the workpiece on the inspection station 22. This reduces the actions required for the workpiece to be inspected, shortens the inspection preparation time, improves inspection efficiency, and reduces equipment costs.

[0081] Embodiment 2

[0082] The difference between this embodiment and the first embodiment lies in that the arrangement positions of the conveying mechanism 4 and the pressing mechanism 5 in this embodiment are different, and the structure of the linkage mechanism is different.

[0083] Specifically, in this embodiment, the transport mechanism 4 and the clamping mechanism 5 are arranged on the same side of the detection station 22. The middle section of the connecting member 61 is hinged between the transport mechanism 4 and the clamping mechanism 5, and the two ends of the connecting member 61 are respectively provided with slide grooves along the length direction thereof. The transport mechanism 4 and the clamping mechanism 5 are respectively connected to the slide grooves located at the two ends of the connecting member 61, and the driving member 413 can drive the transport mechanism 4 to move in a direction perpendicular to the conveying direction of the assembly line so that the transport mechanism 4 moves into or out of the detection station 22. When the driving member 413 drives the transport mechanism 4 to move, the transport mechanism 4 and the clamping mechanism 5 located at the two ends of the connecting member 61 drive the connecting member 61 to rotate around the hinge axis located at the midpoint, so that when the transport mechanism 4 moves into the detection station 22, the clamping mechanism 5 moves out of the detection station 22; and when the transport mechanism 4 moves out of the detection station 22, the clamping mechanism 5 moves into the detection station 22.

[0084] Embodiment 3

[0085] The difference between this embodiment and the second embodiment lies in that the relative positions of the conveying mechanism 4 and the pressing mechanism 5 provided in this embodiment are different, and the structure of the linkage mechanism is different.

[0086] Specifically, in this embodiment, Figure 6 As shown, the conveying mechanism 4 and the clamping mechanism 5 are respectively arranged on the two sides adjacent to the detection station 22, that is, the conveying mechanism 4 is arranged on both sides of the assembly line, and the clamping mechanism 5 is arranged on the assembly line. The moving direction of the conveying mechanism 4 intersects with the moving direction of the clamping mechanism 5. The linkage mechanism includes a connecting member 61, a driving member 413 and a guide block 62. The middle section of the connecting member 61 is hinged between the conveying mechanism 4 and the clamping mechanism 5, and the two ends of the connecting member 61 are respectively connected to the conveying mechanism 4 and the clamping mechanism 5. The driving member 413 can drive the conveying mechanism 4 to move in / out of the detection station 22.

[0087] The guide block 62 is arranged between the connecting member 61 and the clamping mechanism 5, and a guide slope is arranged on the guide block 62. The guide slope can guide the clamping mechanism 5 to move in a direction intersecting with the movement direction of the conveying mechanism 4 when the connecting member 61 pushes against the guide block 62. When the driving member 413 pushes the conveying mechanism 4 to move in a direction perpendicular to the conveying direction of the assembly line, the conveying mechanism 4 drives the connecting member 61 to rotate around the hinge axis located in the middle section of the connecting member 61, so that when the conveying mechanism 4 moves out of the detection station 22, the connecting member 61 pushes against the guide block 62, so that the clamping mechanism 5 moves into the detection station 22.

[0088] Preferably, one end of the connecting member 61 that abuts against the guide block 62 is provided with a roller for pushing against the guide block 62 , so as to reduce the friction force of the connecting member 61 when pushing against the guide block 62 .

[0089] Preferably, the linkage mechanism also includes a first elastic member 63 and a stopper 64, the stopper 64 is fixed to the frame 1, and both ends of the first elastic member 63 are respectively connected between the stopper 64 and the guide block 62, so that when the connecting member 61 is away from the guide block 62, the guide block 62 returns to its initial position.

[0090] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
