Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0031] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] For ease of description, spatial relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device in use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or movement state change, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "on other elements or features". Therefore, the example term "below..." can include the orientations of above and below. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0033] When the traditional positioning device positions the workpiece 1 to be machined, generally, the workpiece 1 to be machined needs to be placed at any position on the positioning plate first, and then the right-angle straightedge is used to push the workpiece 1 to be machined until it completely coincides with the positioning area on the positioning plate. Finally, the workpiece 1 to be machined can be tightly sucked by negative pressure. However, since the opening angle between the two clamping surfaces of the right-angle straightedge is fixed; when the contact surface between the right-angle straightedge and the workpiece 1 to be machined is not compliant and there is an offset, one side of the workpiece 1 to be machined will be stressed and the other side will not be stressed; under the pushing of the right-angle straightedge, the stressed side will first abut against the limit post on the periphery of the positioning area, while the non-stressed side will have an offset distance from its corresponding limit post; at this time, since the workpiece 1 to be machined does not completely coincide with the positioning area on the positioning plate, the right-angle straightedge will continue to push the stressed side of the workpiece 1 to be machined forward, resulting in excessive pressure on the stressed side and a risk of flying out of the positioning area, seriously affecting the positioning reliability of the workpiece 1 to be machined. Based on this, the present application proposes a positioning mechanism that can make the clamping between the clamping surface of the pushing member 320 and the stressed surface of the workpiece 1 to be machined more compliant and reliable. This positioning mechanism can make the workpiece 1 to be machined move along a preset direction, with high positioning accuracy and high positioning efficiency.

[0034] See Figures 1 to 5 As shown in, an embodiment of the present application provides a positioning mechanism, including: a positioning jig 100 having a positioning area for placing the workpiece 1 to be machined; a first limiting component 200 disposed on the positioning jig 100 and surrounding a part of the periphery of the positioning area; a pushing component 300 including a driving member 310 and a pushing member 320, the pushing member 320 is rotatably disposed on the driving member 310, and the driving direction of the driving member 310 faces the first limiting component 200; and a second limiting component 400 disposed on the driving member 310 and located outside the pushing member 320.

[0035] In this embodiment, the pushing member 320 is rotatably disposed on the driving member 310, and the rotation angle of the pushing member 320 is limited by the second limiting component 400. In this way, during the movement of pushing the workpiece 1 to be machined towards the first limiting component 200 by the pushing member 320, the relative position between the pushing member 320 and the workpiece 1 to be machined can be adaptively adjusted, the offset between the two can be eliminated, the clamping surface on the pushing member 320 and the stressed surface on the workpiece 1 to be machined can be made more compliant, the alignment accuracy between the pushing member 320 and the workpiece 1 to be machined can be improved, the positioning accuracy between the workpiece and the positioning area can be improved, and the positioning efficiency can be improved.

[0036] Specifically, the positioning mechanism is configured as a combined component including at least a positioning fixture 100, a first limiting component 200, a pushing component 300, and a second limiting component 400. The positioning fixture 100 can be a near-rectangular plate-shaped structural member, and the outer shape of the positioning area provided thereon is adapted to the outer shape of the workpiece 1 to be processed. The positioning area is used to carry the workpiece 1 to be processed. The first limiting component 200 can be a split structure composed of a plurality of limiting columns. The plurality of limiting columns are spaced apart and enclose a part of the periphery of the positioning area. For example, the plurality of limiting columns are spaced apart on two adjacent sides of the positioning area, and position limitation of the workpiece 1 to be processed is formed at the adjacent sides. The limiting columns can be inserted into the positioning fixture 100 and locked with the positioning fixture 100 by threads, or can be connected and fastened to the positioning fixture 100 by fasteners such as screws / bolts. Here, the connection method between the first limiting component 200 and the positioning fixture 100 is not limited. The pushing component 300 is configured as a combined component including at least a driving member 310 and a pushing member 320. The driving member 310 can be a driving cylinder, which is used to drive the pushing member 320 to move closer to or away from the positioning fixture 100, and to push the workpiece 1 to be processed into the positioning area. The pushing member 320 can be a near-Y-shaped connecting rod structure, which can be rotatably connected to the driving member 310 through a rotating shaft. In this way, during the process of the pushing member 320 pushing the workpiece 1 to move, the pushing member 320 can rotate, so that the pushing member 320 contacts at least two sides of the workpiece 1, and then two acting forces are applied to the workpiece 1 until at least two other sides of the workpiece 1 contact the first limiting component 200 to complete positioning. This can avoid the situation that when only one-directional force is applied during pushing, the workpiece 1 to be processed is easily deflected and contacts the first limiting component 200. At this time, since the workpiece 1 to be processed has not been positioned yet, with the continuous pushing of the driving member 310, the workpiece 1 to be processed is easily pressed and fly out in one direction. The second limiting component 400 can be a split structure composed of at least two limiting columns or limiting blocks. The at least two limiting columns or limiting blocks are respectively arranged on opposite sides of the pushing member 320, so that the pushing member 320 can rotate and adjust between the two limiting columns or limiting blocks, preventing the rotation angle of the pushing member 320 from being too large, resulting in the pushing member 320 being unable to adapt to the workpiece 1, so that the workpiece 1 deviates seriously from the preset moving direction, realizing the range limitation of the rotation angle of the pushing member 320, and making the pushing member 320 in a smaller and appropriate deflection angle range. In this way, both the angle adjustment and position adjustment between the clamping surface and the stress surface can be realized, so that the pushing member 320 applies acting forces in two directions to the workpiece, and small-range rotation adjustment is performed during contact, so that the workpiece 1 to be processed slowly rotates to correct the position, avoiding squeezing the workpiece away when the workpiece 1 to be processed is light, improving the clamping reliability and the positioning accuracy.

[0037] As described above, the positioning mechanism is used as follows: First, place the workpiece 1 to be processed on the positioning area of the positioning fixture 100. At this time, the edge of the workpiece 1 to be processed is not completely in contact with the first limiting component 200, and the position of the workpiece 1 to be processed needs to be further adjusted. Then, drive the pushing member 320 to approach and abut against the workpiece 1 to be processed through the driving member 310. At this time, the clamping surface of the pushing member 320 is not completely attached to the force-bearing surface of the workpiece 1 to be processed. It is necessary to rely on the self-adaptive rotation of the pushing member 320 during the movement to adjust the degree of fit between the clamping surface and the force-bearing surface. Then, during the process of driving the pushing member 320, the pushing member 320 will rotate by itself to adjust the degree of conformity between the clamping surface thereon and the force-bearing surface of the workpiece 1 to be processed, so that the clamping surface applies forces to the workpiece 1 to be processed in two directions, performs correction and adjustment in two directions, and makes the clamping surface completely attached to the force-bearing surface, improving the force uniformity on different force-bearing surfaces of the workpiece 1 to be processed, making the workpiece 1 to be processed move in a preset direction, and improving the positioning efficiency. Then, until the edge of the workpiece 1 to be processed is completely in contact with the first limiting component 200, stop the operation of the driving member 310. At this time, the workpiece 1 to be processed is accurately positioned in the positioning area. Finally, control the driving member 310 to retract and drive the pushing member 320 to move away from the workpiece 1 to be processed to prepare for the next pushing and adjustment operation; the positioned positioning fixture 100 then moves to the next station for the processing of the next process.

[0038] Of course, in other embodiments, the first limiting component 200 can also be an integral block structure, such as an L-shaped or U-shaped integral limiting block, which can enclose and form adjacent two sides or adjacent three sides of the positioning area, and can be fixedly connected to the positioning fixture 100 through fasteners such as screws / bolts. Or, the pushing member 320 can also be in a straight shape or an X shape. For example, when the pushing member 320 is in a straight shape, it can be used in combination with the U-shaped first limiting component 200; when the pushing member 320 is in an X shape, it can be used in combination with the L-shaped first limiting component 200, and it is not limited to the Y shape.

[0039] In a possible implementation manner, the pushing member 320 includes a first clamping arm 321 and a second clamping arm 322. The first clamping arm 321 is rotatably connected to the driving member 310, and the second clamping arm 322 is also rotatably connected to the driving member 310.

[0040] In this embodiment, the specific configuration of the pushing member 320 is optimized. Specifically, the pushing member 320 is configured as a combined member including at least a first clamping arm 321 and a second clamping arm 322. The first clamping arm 321 can be a long rod or a long strip plate-like structure, one end of which can be connected to the output end of the driving member 310 through a rotating shaft, and the other end forms a free end and extends away from the driving member 310; the second clamping arm 322 can be a long rod or a long strip plate-like structure, one end of which can be connected to the driving member 310 through a rotating shaft, and the other end forms a free end and extends away from the driving member 310. For example, both the first clamping arm 321 and the second clamping arm 322 are long strip plate structures, the ends of the two are overlapped and connected to the output end of the driving member 310 through a rotating shaft to form a clamp-like structure. It can be understood that the inner wall surfaces on the two opposite sides when the first clamping arm 321 and the second clamping arm 322 are opened are the clamping surfaces of the pushing member 320, and the workpiece 1 to be processed can be clamped between the first clamping arm 321 and the second clamping arm 322. The structure of the pushing member 320 provided in this example is simple, and both the first clamping arm 321 and the second clamping arm 322 can rotate freely, with stronger flexibility in angle adjustment.

[0041] As Figure 2 and Figure 3 shown, in a preferred embodiment, the pushing member 320 includes a connecting portion 323, a first clamping arm 321 and a second clamping arm 322. The connecting portion 323 is rotatably connected to the driving member 310, and the first clamping arm 321 and the second clamping arm 322 are angularly connected to the connecting portion 323.

[0042] In this embodiment, the specific configuration of the pushing member 320 is optimized. Specifically, the pushing member 320 is configured as a combined member including at least a connecting portion 323, a first clamping arm 321 and a second clamping arm 322. The connecting portion 323 can be a block structure, which can be rotatably connected to the driving member 310 through a rotating shaft. The first clamping arm 321 can be a long rod or a long strip plate-like structure, one end of which is fixedly connected to the connecting portion 323, and the other end forms a free end and extends away from the connecting portion 323; the second clamping arm 322 can be a long rod or a long strip plate-like structure, one end of which is fixedly connected to the connecting portion 323, and the other end forms a free end and extends away from the connecting portion 323; and the second clamping arm 322 and the first clamping arm 321 are arranged at a fixed angle, for example, they can be vertically arranged at a right angle, or they can be arranged at an acute or obtuse angle. The integrity of the pushing member 320 provided in this example is stronger. By rotating one of the clamping arms, the other clamping arm can be driven to rotate synchronously, improving the rotation stability and reliability of the pushing member 320.

[0043] When the workpiece 1 to be processed is a quadrilateral, in a conventional embodiment, the second clamp arm 322 and the first clamp arm 321 are arranged at a fixed angle, and the push member 320 cannot rotate, so there will be a situation where only one clamp arm contacts the workpiece, that is, the push member 320 pushes only one side of the workpiece and only applies a force in one direction to the workpiece. For a relatively light workpiece, it is difficult to adjust the angle adaptively during the movement, and the workpiece will continue to deviate under the action of the force, so that only one side of the two sides of the workpiece 1 to be processed that are away from the push member 320 is close to the first limit assembly 200. Since the workpiece has not been completely pushed into place, when the push member 320 continues to push, it is easy to squeeze the workpiece away.

[0044] In the present embodiment, the push member 320 is rotatably connected to the driving member 310. When the push member 320 is pushed, when the adjacent two sides of the workpiece are offset from the two clamping arms, the push member 320 can adapt to the two sides of the workpiece to make a small range of rotation, so that the two clamping arms can contact the two sides of the workpiece. Then, at the time of final positioning, although the workpiece also contacts one side of the first limit assembly 200 first, since the two clamping arms continuously apply forces in two directions to the adjacent two sides of the workpiece, the push member 320 and the workpiece will be deflected and adjusted until the workpiece is close to both sides of the first limit assembly 200 to complete the positioning.

[0045] like Figure 2 and Figure 3 As shown, in a possible implementation manner, the push member 320 further includes a movable wheel 324 , and the movable wheel 324 is rotatably connected to the free ends of the first clamping arm 321 and the second clamping arm 322 .

[0046] In this embodiment, the specific configuration of the push member 320 is further optimized. Specifically, the push member 320 is configured as a composite component including at least a first clamping arm 321, a second clamping arm 322 and a movable wheel 324. The movable wheel 324 can be arranged below the first clamping arm 321 and the second clamping arm 322, and is used to abut against the workpiece 1 to be processed; since the movable wheel 324 has greater flexibility and freedom, it can reduce the friction between the workpiece 1 to be processed, and gradually correct the position between the movable wheel 324 and the workpiece 1 to be processed during the movement process until the workpiece 1 to be processed is correctly positioned against the edge, avoiding the situation where one movable wheel 324 pushes the workpiece 1 to be processed to move and position, reducing the risk of the workpiece 1 to be processed being squeezed and flying out, and improving the positioning accuracy. The push member 320 provided in this example has greater flexibility and freedom. The position of one of the force-bearing surfaces of the workpiece 1 to be processed can be adjusted by the first clamping arm 321 and the movable wheel 324 thereon. At the same time, the position of the other force-bearing surface of the workpiece 1 to be processed can be adjusted by the second clamping arm 322 and the movable wheel 324 thereon, and the single-sided adjustment accuracy is higher.

[0047] Alternatively, configure the pushing member 320 as a combined component including at least a connecting portion 323, a first clamping arm 321, a second clamping arm 322, and a movable wheel 324. The movable wheel 324 can be disposed below the first clamping arm 321 and the second clamping arm 322 for abutting against the workpiece 1 to be processed. Due to the greater flexibility and freedom of the movable wheel 324, it can reduce the friction with the workpiece 1 to be processed, gradually correct the position between the movable wheel 324 and the workpiece 1 to be processed during the movement until the edge positioning of the workpiece 1 to be processed is correct, avoid the situation where a movable wheel 324 pushes the workpiece 1 to be processed for movement and positioning, reduce the risk of the workpiece 1 to be processed being squeezed and flying out, and improve the positioning accuracy. The pushing member 320 provided in this example combines integrity and flexibility, has stronger reliability in angle adjustment, and higher adjustment efficiency.

[0048] As Figure 3 shown, in a possible implementation manner, the second limiting component 400 includes a second limiting member 410 and a third limiting member 420. The second limiting member 410 is spaced from the first clamping arm 321 and is located outside the first clamping arm 321. The third limiting member 420 is spaced from the second clamping arm 322 and is located outside the second clamping arm 322.

[0049] In this embodiment, the specific configuration of the second limiting component 400 is optimized. Specifically, configure the second limiting component 400 as a combined component including at least the second limiting member 410 and the third limiting member 420. The second limiting member 410 can be a limiting post, which can be connected to the driving member 310 by means of bonding, welding, or plugging. The third limiting member 420 can be a limiting post, which can be connected to the driving member 310 by means of bonding, welding, or plugging. At the same time, the second limiting member 410 and the third limiting member 420 are respectively disposed outside the first clamping arm 321 and the second clamping arm 322 to limit the maximum rotation range of the first clamping arm 321 and the second clamping arm 322, so that the pushing member 320 rotates within a suitable rotation angle range.

[0050] Of course, in other embodiments, the second limiting component 400 can also be an integral block structure, such as a C-shaped or U-shaped integral limiting block, which is disposed on the driving member 310. At this time, the connection portion between the pushing member 320 and the driving member 310 is received in the second limiting component 400, and the free end of the pushing member 320 extends out of the opening of the second limiting component 400, and the pushing member 320 is limited between the openings of the integral limiting block.

[0051] As Figure 2 shown, in a possible implementation manner, a sucking member 500 is further included. The sucking member 500 is disposed in the positioning area of the positioning jig 100.

[0052] In this embodiment, the specific configuration of the positioning mechanism is further optimized. Specifically, the positioning mechanism is configured as a combined component including at least a positioning fixture 100, a first limiting component 200, a pushing component 300, a second limiting component 400, and a sucking component 500. The sucking component 500 can be a vacuum negative pressure suction nozzle, which is arranged below the positioning area and is used to adsorb the workpiece 1 to be processed positioned on the positioning area, further enhancing the connection tightness between the workpiece 1 to be processed and the positioning fixture 100 and improving the positioning reliability of the positioning mechanism.

[0053] As Figure 1 shown, in a possible implementation manner, it further includes a position detection component 600, and the position detection component 600 is arranged above the positioning fixture 100.

[0054] In this embodiment, the specific configuration of the positioning mechanism is further optimized. Specifically, the positioning mechanism is configured as a combined component including at least a positioning fixture 100, a first limiting component 200, a pushing component 300, a second limiting component 400, and a position detection component 600. The position detection component 600 can be an industrial camera, which is arranged above the positioning fixture 100 and is used to obtain and detect whether the contour of the workpiece 1 to be processed completely coincides with the contour of the positioning area, and to monitor the positioning effect in real time. When the two contours do not completely overlap, the workpiece 1 to be processed can be further pushed by the pushing member 320 until the two completely coincide, timely correcting the position of the workpiece 1 to be processed and improving the positioning accuracy.

[0055] In addition, as Figure 1 , Figure 4 and Figure 5 shown, the present application also provides a processing device, including: a base 10, a processing platform 20, and a support 30. The processing platform 20 is movably arranged on the base 10, and the support 30 is arranged on the base 10 close to the processing platform 20; the positioning mechanism as described above, the positioning fixture 100 of the positioning mechanism is arranged on the processing platform 20, and the pushing component 300 of the positioning mechanism is arranged on the support 30.

[0056] In this embodiment, a processing device for positioning a workpiece 1 to be processed is provided. When the workpiece 1 to be processed is positioned, during the process of the pushing member 320 of the positioning mechanism pushing the workpiece 1 to be processed, the relative position between the pushing member 320 and the workpiece 1 to be processed is adjusted practically to eliminate the offset therebetween, making the clamping surface on the pushing member 320 more conformable to the stress surface on the workpiece 1 to be processed and improving the alignment accuracy between the pushing member 320 and the workpiece 1 to be processed; at the same time, the stress between the pushing member 320 and the workpiece 1 to be processed without offset is uniform, enabling the workpiece 1 to be processed to move in a preset direction, improving the positioning accuracy between the coded workpiece and the positioning area, and improving the positioning efficiency.

The base 10 is configured on the ground and is used to provide support for other components. The processing platform 20 can be a circular turntable structure, which is rotatably configured on the top of the base 10; the positioning and processing of the workpiece 1 to be processed can be realized by rotating the processing platform 20. The support 30 can be a support column, which can be connected to the base 10 through fasteners such as bolts / screws; the top end of the support 30 extends out of the top end of the processing platform 20 to provide sufficient support height for the positioning mechanism. For the specific structure of the positioning mechanism, refer to the above embodiment. It can include a cylinder and a pushing connecting rod arranged at the output end of the cylinder. The cylinder can be connected to the side wall of the support 30 through a horizontally arranged connecting plate. The output end of the cylinder faces the processing platform 20 and can drive the pushing connecting rod to press against the workpiece 1 to be processed and move it in the direction close to the first limiting component 200 until the workpiece 1 to be processed abuts against the first limiting component 200, so as to realize the positioning of the edge of the workpiece 1 to be processed and the positioning area; and, after the positioning is completed, the cylinder can drive the pushing connecting rod to release the workpiece 1 to be processed and move it in the direction away from the first limiting component 200 to realize the recovery and reset of the pushing connecting rod, so as to perform the positioning adjustment of the next workpiece 1 to be processed. The conveying unit 40 can include a belt line and guardrails arranged on both sides of the belt line, etc. The tray is placed on the belt line for transmission, and the guardrails can prevent the tray from being overturned during transmission. The loading unit 50 can adopt a SCARA four-axis robot with a picking fixture. The picking fixture is composed of a rotating motor module and a suction cup module. The suction cup module can be used for vacuum adsorption of the workpiece 1 to be processed, and the rotating motor module can drive the suction cup module to rotate and change direction; compared with the traditional rotating cylinder, the loading unit 50 provided in this example has higher precision, the rotation process is controllable and stable, and the risk of the workpiece 1 to be processed falling to the ground during rotation can be reduced; the loading unit 50 is arranged between the conveying unit 40 and the processing platform 20 to transfer the workpiece 1 to be processed on the conveying unit 40 to the positioning fixture 100 on the processing platform 20, and then move the workpiece 1 to be processed to the positioning area of the positioning fixture 100 through the pushing component of the positioning mechanism, and make the edge of the workpiece 1 to be processed close to the first limiting component 200, so as to improve the positioning accuracy of the workpiece 1 to be processed and the processing accuracy and yield of the subsequent workpiece 1 to be processed.The blanking unit 60 can adopt a SCARA four-axis robot with a material-taking fixture.

It is arranged between the processing platform 20 and the conveying unit 40 to transfer the finished workpieces such as those with coding, chip mounting, or dispensing processed on the processing platform 20 from the positioning fixture 100 on the processing platform 20 to the tray of the blanking unit 60, so as to enable them to enter the next process. The processing device 70 can be a coding machine, a chip mounter, a dispensing machine, etc., which is used for precisely processing the workpieces to be processed with fixed positions, improving the processing efficiency and processing effect, and improving the product yield. That is to say, the processing equipment provided in this application is not only applicable to the coding process of the workpiece 1 to be processed, but also applicable to the chip mounting process or the dispensing process of the workpiece 1 to be processed, etc., as long as it is a processing process that positions the workpiece 1 to be processed using the positioning mechanism provided in this application.

[0060] As Figure 1 and Figure 4 shown, in a possible implementation manner, a plurality of stations are provided on the processing platform 20, and the plurality of stations are arranged at intervals along the circumferential direction of the processing platform 20 on the edge of the processing platform 20. A plurality of positioning fixtures 100 are provided, and one positioning fixture 100 corresponds to one station. With such an arrangement, a plurality of positioning fixtures 100 can share a pushing component 300, saving costs; and at the same time, the assembly line production of a plurality of workpieces 1 to be processed can be realized, improving the production efficiency of the processing equipment.

[0061] In a possible implementation manner, the processing device 70 includes a coding unit 73 arranged close to the processing platform 20, and the coding unit 73 is located between the feeding unit 50 and the blanking unit 60.

[0062] Furthermore, the processing device 70 further includes a product cleanliness detection unit 71, a laser ranging unit 72, a code reading unit 74, and a recycling unit 75. The support 30, the product cleanliness detection unit 71, the laser ranging unit 72, the coding unit 73, the code reading unit 74, and the recycling unit 75 are arranged in sequence along the moving direction of the processing platform 20.

[0063] Specifically, the product cleanliness detection unit 71 can be a detection camera, which is arranged at the discharge end of the feeding unit 50 and is used to detect whether there are impurities such as dust on the workpiece 1 to be processed on the positioning jig 100. For example, when impurities are detected at the preset coding position, the subsequent coding unit 73 can be offset to a place without impurities according to the size of the impurities for coding, so as to avoid the influence of impurities on the coding effect and improve the coding yield. The laser ranging unit 72 is arranged at the discharge end of the product cleanliness detection unit 71 and mainly uses a laser rangefinder to accurately measure the height of the workpiece 1 to be processed in the vertical direction, which is convenient for subsequent coding and code reading. The coding unit 73 can be a laser coder, which is arranged between the discharge end of the laser ranging unit 72 and the discharging unit 60. It can adjust the coding according to the detection data of the position detector 600, the product cleanliness detection unit 71 and the laser ranging unit 72. It realizes its displacement in the vertical direction through a motor, a linear module, etc., and adjusts the light beam in the X and Y planes through a galvanometer scanner to realize the coding of the workpiece 1 to be processed. The code reading unit 74 can be a code reading detector, which is used to detect whether the label processed by the coding unit 73 is qualified; a micro electric slide table is configured on the code reading unit 74, and it can be lifted and lowered according to the vertical direction detection data of the laser ranging unit 72. When the detection result is qualified, the discharging unit 60 takes away the qualified finished products and places them in the tray in the discharging area 43 of the conveying unit 40 for the next process; when the detection result is unqualified, the discharging unit 60 takes away the unqualified defective products and places them in the defective product recycling unit 75 for recycling. The recycling unit 75 can be a drawer-type defective product bin, which is arranged on the base 10 and is located between the code reading unit 74 and the discharging unit 60, and is used to accommodate the defective products that appear during the coding process. The processing equipment provided in this example is used to realize the coding process of the workpiece 1 to be processed, and the obtained product has high coding accuracy and good coding effect.

[0064] Such as Figure 4 And Figure 5As shown, in one example, the conveying unit 40 may include a loading area 41, a buffer area 42 and a unloading area 43 which are arranged in sequence, the loading area 41 is correspondingly arranged at the feeding end of the processing platform 20, the unloading area 43 is correspondingly arranged at the discharging end of the processing platform 20, and the buffer area 42 is connected to the discharging end of the loading area 41. The material tray enters the conveying unit 40 from the starting end of the loading area 41 and moves along the conveying line. The end of the loading area 41 is a positioning area, in which a blocking cylinder and a side positioning cylinder are provided. After the material tray is transmitted to the positioning area, the blocking cylinder first stops the material tray, and then the side positioning cylinder pushes the material tray to the side to achieve positioning, and then the loading unit 50 places the products of the workpiece 1 to be processed in the positioned material tray in the positioning fixture 100 of the processing platform 20 in sequence; the starting end of the unloading area 43 is a positioning area, in which a blocking cylinder and a side positioning cylinder are provided. After the material tray is transmitted to the positioning area, the blocking cylinder first stops the material tray, and then the side positioning cylinder pushes the material tray to the side to achieve positioning, and then the unloading unit 60 places the qualified products in the positioned material tray in sequence.

[0065] Since defective products may appear during the coding process, when the defective products are placed in the recovery unit 75, the number of workpieces 1 to be processed in the loading area 41 may be different from the number of qualified products in the unloading area 43. Based on this, a buffer zone 42 is added between the loading area 41 and the unloading area 43. In this way, when the workpieces to be processed in the tray of the loading area 41 are taken out and the tray of the unloading area 43 is not full of qualified products, the tray of the loading area 41 continues to be transferred to the buffer zone 42, while the tray of the unloading area 43 does not move until it is full of products. The conveying unit 40 provided in this example has a higher tolerance rate for the number of workpieces 1 to be processed and a higher production efficiency.
