[0030] Example 1

[0031] like Figure 1 , Figure 2 as well as Figure 3As shown in Embodiment 1, this utility model provides a conveying mechanism 100 for conveying sheet metal. The conveying mechanism 100 includes a conveying component 110 and two clapping components 120. The conveying component 110 is used to convey sheet metal along a first direction. The clapping component 120 includes a translation drive unit and clapping pieces. The translation drive unit is installed on the conveying component 110 and is used to drive the clapping pieces to move along a second direction. The clapping pieces of the two clapping components 120 can move towards each other to clapping and positioning the sheet metal. The first direction and the second direction intersect.

[0032] When the conveying mechanism 100 is used to convey sheet metal, the sheet metal is first placed in the conveying assembly 110, and then the conveying assembly 110 conveys the sheet metal along the first direction. When the conveying assembly conveys the sheet metal to the loading position along the first direction, the translation drive unit drives the clapping component to move relative to the conveying assembly along the second direction. The clapping components of the two clapping assemblies can move towards each other to clap and position the sheet metal to avoid deviation when the sheet metal is loaded and improve the accuracy of sheet metal detection.

[0033] In one specific embodiment, the conveying mechanism 100 is used to convey the circuit board to be inspected. When the conveying mechanism 100 is used to convey the circuit board to be inspected, the circuit board to be inspected is first placed on the conveying assembly 110. Then the conveying assembly 110 conveys the circuit board to be inspected along the first direction. When the conveying assembly conveys the board to the loading position along the first direction, the translation drive unit drives the clapping member to move relative to the conveying assembly along the second direction. The clapping members of the two clapping assemblies can move towards each other to clap and position the circuit board to be inspected, so as to avoid the circuit board to be inspected from shifting when loading and improve the accuracy of board inspection.

[0034] In one specific embodiment, such as Figure 3 As shown, the conveying mechanism 100 also includes a guide assembly, which is mounted on the conveying assembly 110. The clapper is mounted on the guide assembly, and a translation drive unit is used to drive the clapper to move relative to the conveying assembly 110 in a second direction via the guide assembly. The guide assembly can guide the movement of the clapper, ensuring that the clapper always moves relative to the conveying assembly 110 in the second direction, preventing the translation drive unit from moving the clapper in other directions while driving it relative to the conveying assembly 110, thus ensuring the accuracy of the clapper's positioning.

[0035] In this embodiment, the guiding component includes a guide rail 121 extending along a second direction, and a slidably mounted plate on the guide rail 121. The slidably mounted plate has a groove that slidably engages with the guide rail 121, allowing the slidably mounted plate to slide along the guide rail 121. Alternatively, the guiding component can also be a guide groove extending along the second direction, with the slidably mounted plate on it. The slidably mounted plate has a guide rail that limits its sliding within the guide groove, allowing the slidably mounted plate to slide along the guide groove. The guiding component can also be other guiding members, such as a guide rod.

[0036] In one feasible implementation, in order to improve the patting and shaping quality of the plate by the patting assembly 120, the length of the patting end of the patting member along the first direction needs to be relatively long. Therefore, the guide assembly includes at least two guide rails 121 spaced apart along the first direction. The patting member is slidably mounted across each guide rail 121, and each guide rail 121 simultaneously guides the patting member, thereby improving the movement stability of the patting member.

[0037] The guide assembly may include two guide rails 121 spaced apart along a first direction, or it may include three or other numbers of guide rails 121 spaced apart along a first direction.

[0038] The conveying mechanism 100 provided in one embodiment of this utility model, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the slapping device includes a sliding seat 122 and a shaping plate 123. The sliding seat 122 is slidably mounted on the guide rail 121, and the shaping plate 123 is mounted on the sliding seat 122. The translation drive unit can drive the sliding seat 122 to move relative to the guide rail 121 in a second direction, and the sliding seat 122 drives the shaping plate 123 to move in the second direction to adjust the position of the sheet metal. Of course, it is understood that the slapping device can also have other structures. For example, one end of the shaping plate 123 is slidably mounted on the guide rail 121, and the other end of the shaping plate 123 can be used to slap and position the sheet metal.

[0039] In this embodiment, the conveying assembly 110 includes a conveying base frame, a rotary drive unit, and a plurality of conveying rollers 111. Each conveying roller 111 is rotatably mounted on the conveying base frame at intervals along a first direction, and the axis of the conveying roller 111 extends along a second direction. The rotary drive unit is used to drive the conveying roller 111 to rotate relative to the conveying base frame. When the conveying assembly 110 is used to convey sheet metal, the sheet metal is first placed on the conveying roller 111, and the rotary drive unit drives the conveying roller 111 to rotate relative to the conveying base frame, thereby causing the sheet metal to move relative to the conveying base frame along the first direction.

[0040] Of course, it is understandable that the conveying assembly 110 can also be made of other components, such as belt conveyor, screw conveyor, etc.

[0041] In this embodiment, specifically, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the conveying base frame includes a base plate 112 and a side plate 113. The side plate 113 is installed on one side of the base plate 112, and the conveying roller 111 is rotatably installed on the side plate 113. The translation drive unit is installed on the side of the base plate 112 away from the conveying roller 111. A through hole extending in the second direction is provided on the base plate 112, and the clapping end of the clapping component can pass through the through hole to position the clapping.

[0042] The translation drive unit is installed on the side of the base plate 112 away from the conveyor roller 111, which avoids the translation drive unit affecting the installation and rotation of the conveyor roller 111. A through hole extending in the second direction is provided on the base plate 112, allowing the striking end of the striking plate component to pass through the through hole for striking and positioning the sheet material. The through hole extending in the second direction on the base plate 112 allows the striking plate component, installed on the side of the base plate 112 away from the conveyor roller 111, to extend through the through hole to the side of the base plate 112 closer to the conveyor roller 111, facilitating the striking and positioning of the sheet material.

[0043] Since the sheet material is placed on the conveyor roller 111, the rotary drive unit drives the conveyor roller 111 to rotate relative to the conveyor base, thereby causing the sheet material to move relative to the conveyor base in the first direction. Therefore, the height of the shaping plate 123 must be higher than the top of the conveyor roller 111 so that the shaping plate 123 can adjust the position of the sheet material placed on the conveyor roller 111. The translation drive unit is installed on the side of the base plate 112 away from the conveyor roller 111. Therefore, a clearance hole 124 can be opened in the clapping part, and the conveyor roller 111 passes through the clearance hole 124 so that the clapping end of the shaping plate 123 extends above the top of the conveyor roller 111.

[0044] In one feasible embodiment, the inner diameter of the clearance hole 124 is 1 to 5 mm larger than the outer diameter of the conveyor roller 111.

[0045] In this embodiment, the conveying assembly 110 further includes a stop 117 and a sensing sensor 118. The stop 117 is mounted on the conveying base and is used to position the sheet metal along a first direction. The sensing sensor 118 is used to sense the position of the sheet metal. When the conveying assembly 110 is used to convey sheet metal, the sheet metal is first placed on the conveying roller 111. The rotation drive unit drives the conveying roller 111 to rotate relative to the conveying base, thereby moving the sheet metal relative to the conveying base along the first direction until the sheet metal abuts against the stop 117, positioning the sheet metal along the first direction. At this time, the sensing sensor 118 senses the sheet metal and controls the translation drive unit to drive the clapping component to move along the second direction. The clapping components of the two clapping assemblies 120 can move towards each other to clap and position the sheet metal.

[0046] In one feasible implementation, the stopper 117 is a stop plate, which is fixedly installed on the conveyor base frame by bolts. The sensing sensor 118 is a proximity sensor. When the sheet material abuts against the stopper, the proximity sensor detects the sheet material and controls the translation drive unit to drive the clapping component to move along the second direction. The clapping components of the two clapping assemblies 120 can move towards each other to position the sheet material. Multiple sensing sensors 118 can be provided, and multiple sensing sensors 118 are installed at intervals along the second direction on the stop plate.

[0047] Of course, it is understandable that other components can be used for the material stop, such as a material stop bar; the material stop can also be fixed to the conveyor base frame in other ways, such as riveting or welding; the sensing sensor can also be other components, such as a photoelectric sensor or a position sensor, etc., without limitation.

[0048] The conveying mechanism 100 provided in one embodiment of this utility model, such as Figure 1 As shown, the rotary drive unit includes a rotary drive component 114, a conveyor chain 115, and a conveyor sprocket 116. The conveyor sprocket 116 is mounted on the conveyor roller 111, and the rotary drive component 114 is mounted on the conveyor base. The output end of the rotary drive component 114 can drive the conveyor sprocket 116 to rotate via the conveyor chain 115. Each conveyor roller 111 has a conveyor sprocket 116 mounted at one end. The rotation of the conveyor sprocket 116 can drive the conveyor roller 111 to rotate relative to the conveyor base. The conveyor chain 115 is simultaneously connected to each conveyor sprocket 116. The output end of the rotary drive component 114 drives the conveyor chain 115 to move, thereby driving each conveyor sprocket 116 to rotate, and thus causing each conveyor roller 111 to rotate relative to the conveyor base.

[0049] Of course, it is understandable that the rotary drive unit can also have other structures, such as belt drive to rotate the conveyor roller 111 relative to the conveyor base. The rotary drive unit includes a rotary drive component 114, a conveyor belt, and conveyor wheels. The conveyor wheels are mounted on the conveyor roller 111, and the rotary drive component 114 is mounted on the conveyor base. The output end of the rotary drive component 114 is connected to the conveyor wheels via the conveyor belt. Each conveyor roller 111 has a conveyor wheel mounted at one end. The rotation of the conveyor wheels can drive the conveyor roller 111 to rotate relative to the conveyor base. The conveyor belt is simultaneously connected to each conveyor wheel. The output end of the rotary drive component 114 drives the conveyor belt to move, thereby driving each conveyor wheel to rotate, and thus causing each conveyor roller 111 to rotate relative to the conveyor base.

[0050] In this embodiment, as Figure 3 As shown, the translation drive unit includes a first rotation drive component 125, a conveyor belt 126, and a steering wheel 127. Both the first rotation drive component 125 and the steering wheel 127 are mounted on the conveying assembly 110 and are spaced apart along a second direction. The conveyor belt 126 is fitted onto the output ends of the steering wheel 127 and the first rotation drive component 125. The output ends of the first rotation drive component 125 can drive the steering wheel 127 to rotate via the conveyor belt 126. A clapper is connected to the conveyor belt 126. The first rotation drive component 125 and the steering wheel 127 are spaced apart along the second direction so that the conveyor belt 126, fitted onto the output ends of the steering wheel 127 and the first rotation drive component 125, extends along the second direction. The clapper is connected to the conveyor belt 126, thereby allowing the conveyor belt 126 to drive the clapper to move along the second direction.

[0051] Of course, it is understandable that the translation drive unit can also be a linear actuator, with the clapper mounted on the output end of the linear actuator, which can drive the clapper to move in a second direction. For example, the linear actuator can be a telescopic cylinder, a telescopic hydraulic cylinder, or a linear motor, with the clapper mounted on the output end of the telescopic cylinder, telescopic hydraulic cylinder, or linear motor.

[0052] In another embodiment, the translation drive unit includes a second rotation drive member, a drive gear, and a transmission rack. The second rotation drive member is mounted on the conveying assembly 110, the drive gear is mounted on the output end of the second rotation drive member, and the transmission rack is mounted on the clapper member. The drive gear meshes with the transmission rack. The second rotation drive member can drive the drive gear to rotate and drive the transmission rack to move along the second direction, thereby driving the clapper member to move along the second direction.

[0053] In this embodiment, as Figure 3As shown, the clapper assembly also includes a clamping member 128, which is mounted on the clapper and can clamp and fix it to the conveyor belt 126. When it is necessary to connect the clapper to the conveyor belt 126, the clamping member 128 is clamped and fixed to the conveyor belt 126. When it is necessary to remove the clapper from the conveyor belt 126, the clamping member 128 can be removed from the conveyor belt 126.

[0054] In one feasible implementation, the clamping element 128 may be a jaw, chuck, pressure plate, or the like.

Since this feeding device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0057] When the feeding device is needed for feeding, the sheet material is first placed on the conveying assembly 110, and then the conveying assembly 110 conveys the sheet material along the first direction. When the conveying assembly conveys the sheet material to the feeding position along the first direction, the translation drive unit drives the clapping component to move relative to the conveying assembly along the second direction. The clapping components of the two clapping assemblies can move towards each other to clap and position the sheet material. Finally, the gripping mechanism grips the sheet material that has been clapped and positioned on the conveying mechanism 100.

[0058] Example 3

[0059] like Figures 1 to 3 As shown in Embodiment 3, this utility model provides a testing device, which includes a testing apparatus and a feeding device as provided in any of the above embodiments. The gripping mechanism can grip the sheet material conveyed by the conveying mechanism 100 to the testing position of the testing apparatus.

Since this testing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] When the testing equipment is needed for testing, the sheet material is first placed on the conveying assembly 110. Then, the conveying assembly 110 conveys the sheet material along the first direction. When the conveying assembly conveys the sheet material to the loading position along the first direction, the translation drive unit drives the clapping component to move relative to the conveying assembly along the second direction. The clapping components of the two clapping assemblies can move towards each other to clap and position the sheet material. Then, the gripping mechanism grips the sheet material after clapping and positioning on the conveying mechanism 100 and moves it to the test position of the testing device. Finally, the testing device tests the sheet material located at the test position.

[0061] The testing device can be any type of testing device. Of course, it is understood that the testing device can also be a processing device capable of processing the sheet material.

[0062] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
