Description

Technical Field

[0001] This utility model relates to the field of marking mechanisms, specifically to a marking mechanism used in an automatic marking and testing machine. Background Technology

[0002] Automatic marking and testing machines use a focused high-energy laser beam to induce physical or chemical changes on the surface of materials, thereby forming text, QR codes, barcodes, or patterns.

[0003] When the marking and testing machine is working, the internal marking mechanism will perform reciprocating marking operations on the workpieces transported from the top of the transmission device. However, some workpieces will tilt during transport, which will cause the marking mechanism to produce skewed markings, thereby reducing the yield of finished products after processing. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide a marking mechanism for an automatic marking and testing machine. This solves the technical problem that in the prior art, some workpieces will tilt during transmission, which will cause the marking mechanism to be skewed during operation, thereby reducing the yield of the workpiece after processing.

[0005] The purpose of this utility model is achieved through the following means: a marking mechanism for an automatic marking and testing machine, comprising a base, a conveyor belt device, a bracket, and a servo lifting device. The conveyor belt device and the bracket are both mounted on the upper end of the base. The servo lifting device is mounted on the top of the inner cavity of the bracket, and a marking module is connected to the output end of the bracket. Push plates are slidably connected to the left and right sides of the lower part of the marking module. A connecting rod is connected to the outside of the push plate through a hinge, and the other end of the connecting rod is connected to the bracket. A correction mechanism is mounted on the inner end face of the push plate.

[0006] The correction mechanism includes a first airbag, with curved tubes connected to both the left and right ends of the first airbag, and a second airbag connected to the other end of the curved tubes. Correction plates are installed on the inner end faces of the two second airbags.

[0007] Furthermore, the marking module has sliding grooves on both the left and right sides of its upper end. A slider is slidably connected inside the sliding groove. The slider is connected to the push plate. The sliding groove can cooperate with the slider to guide the push plate to move in a straight line.

[0008] Furthermore, the exteriors of both the first and second airbags are glued to the inner cavity of the push plate. The first and second airbags are connected by adhesive, which facilitates the disassembly and maintenance of the first and second airbags. The first airbag includes two sets of airbags, and the two sets of airbags are respectively connected to the curved tube. The gas inside the two sets of airbags can be completely discharged into the interior of the second airbag, so that the extension and retraction lengths of the two second airbags are the same.

[0009] Furthermore, the correction plate is externally connected to a guide arm, and the outside of the guide arm is slidably connected to the inner cavity of the push plate. The guide arm can guide the correction plate, thereby causing the correction plate to move linearly.

[0010] Furthermore, a guide slider is connected to the top of the correction plate, and a groove is provided at the top of the inner cavity of the connecting rod to slide in connection with the guide slider. The groove is slidably connected to the guide slider, and the guide slider can guide the correction plate, thereby causing the correction plate to move in a straight line.

[0011] Furthermore, the ends of the correction plate and the first airbag away from the inner cavity of the push plate are both equipped with rubber pads. The rubber pads can prevent the correction plate and the first airbag from being damaged by friction with the workpiece when they come into contact with it.

[0012] The beneficial effects of this utility model are as follows: when the workpiece is being marked, the added connecting rod and push plate automatically clamp and fix the workpiece, preventing the workpiece from moving due to environmental interference during marking. At the same time, when the workpiece is fixed, the added first airbag, bent pipe, second airbag and correction plate automatically correct the position of the workpiece, preventing the position of the workpiece from shifting, thereby avoiding workpiece marking failure.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. This embodiment refers to... Figure 1 and Figure 2 The marking mechanism for the automatic marking test machine includes a base 1, a conveyor belt device 2, a bracket 3, and a servo lifting device 4. The conveyor belt device 2 and the bracket 3 are both mounted on the upper end of the base 1. The servo lifting device 4 is mounted on the top of the inner cavity of the bracket 3. The output end of the bracket 3 is connected to a marking module 5. Push plates 61 are slidably connected to the left and right sides of the lower part of the marking module 5. The outside of the push plate 61 is connected to a connecting rod 6 through a hinge. The other end of the connecting rod 6 is connected to the bracket 3. The inner end face of the push plate 61 is equipped with a correction mechanism 7.

[0019] Please see Figure 3 and Figure 4 The conveyor belt device 2 is a common conveyor device in the prior art, and is equipped with control sensors on the outside. The base 1 is used to support the conveyor belt device 2 and the bracket 3. The bracket 3 is used to support the servo lifting device 4. The servo lifting device 4 is a servo lifting platform in the prior art, which is used to drive the marking module 5. The marking module 5 is a common marking device in the prior art, which is used to perform marking operations on the outside of the workpiece. The connecting rod 6 is used to drive the push plate 61. The push plate 61 can clamp and fix the workpiece.

[0020] The calibration mechanism 7 includes a first airbag 71, with bent tubes 72 connected to both the left and right ends of the first airbag 71, and a second airbag 73 connected to the other end of the bent tubes 72. Calibration plates 74 are installed on the inner end faces of both second airbags 73.

[0021] The gas inside the first airbag 71 can be compressed and discharged into the second airbag 73 through the bend 72, thereby causing the second airbag 73 to expand and contract. The second airbag 73 can then drive the correction plate 74 to move, and the correction plate 74 can correct the position of the workpiece.

[0022] The upper left and right sides of the marking module 5 are provided with sliding grooves 51. A slider is slidably connected inside the sliding groove 51. The slider is connected to the push plate 61. The sliding groove 51 can cooperate with the slider to guide the push plate 61 to move in a straight line.

[0023] The exterior of the first airbag 71 and the second airbag 73 are both glued to the inner cavity of the push plate 61. The first airbag 71 and the second airbag 73 are connected by adhesive to facilitate disassembly and maintenance of the first airbag 71 and the second airbag 73. The first airbag 71 includes two sets of airbags, and the two sets of airbags are respectively connected to the bend tube 72. The gas inside the two sets of airbags can be completely discharged into the interior of the second airbag 73, so that the extension and retraction lengths of the two second airbags 73 are the same.

[0024] The external connection of the correction plate 74 is a guide arm 75, and the external part of the guide arm 75 is slidably connected to the inner cavity of the push plate 61. The guide arm 75 can guide the correction plate 74, thereby causing the correction plate 74 to move linearly.

[0025] The top of the calibration plate 74 is connected to a guide slider 76. The top of the inner cavity of the connecting rod 6 is provided with a groove that is slidably connected to the guide slider 76. The groove is slidably connected to the guide slider 76, and the guide slider 76 can guide the calibration plate 74, thereby causing the calibration plate 74 to move linearly.

[0026] Both the correction plate 74 and the first airbag 71 are equipped with rubber pads at the ends away from the inner cavity of the push plate 61. The rubber pads can prevent the correction plate 74 and the first airbag 71 from being damaged by friction with the workpiece when they come into contact with it.

[0027] First, the workpiece is placed on top of the conveyor belt device 2. The conveyor belt device 2 is started to transport the workpiece. When the workpiece moves to the middle of the inner cavity of the bracket 3, the conveyor belt device 2 stops moving through the internal control module. The servo lifting device 4 drives the marking module 5 to descend and perform marking operations on the workpiece. At the same time, the two connecting rods 6 drive the two push plates 61 to move relative to each other, thereby clamping and fixing the workpiece. When the push plate 61 clamps the workpiece, the first air bladder 71 inside is compressed. The gas is discharged into the second air bladder 73 through the bend pipe 72 to expand and contract left and right, thereby driving the two correction plates 74 to move and correct the position of the workpiece. Finally, the workpiece is marked. The marking module 5, connecting rods 6 and correction mechanism 7 return to their original positions, and the conveyor belt device 2 restarts to resume the transport operation.

[0028] When the workpiece is being marked, the added connecting rod 6 and push plate 61 automatically clamp and fix the workpiece, preventing it from moving due to environmental interference during marking. At the same time, the added first airbag 71, bend 72, second airbag 73 and correction plate 74 automatically correct the position of the workpiece when it is fixed, preventing the workpiece from shifting and thus avoiding marking failure.

[0029] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
