Description

Technical Field

[0001] This invention relates to the field of industrial CT technology, and in particular to a high-energy industrial CT system with a composite scanning mode. Background Technology

[0002] Currently, most mainstream high-energy industrial CT inspection equipment on the market adopts a layout scheme of horizontal and vertical linear movement for its X-ray generating unit and signal receiving detector. The corresponding workpiece movement modes are mainly rotation and linear translation. This type of imaging architecture imposes strict constraints on the placement and motion adaptability of the inspected parts: if the parts cannot complete the rotation due to structural, shape, or assembly limitations, or cannot be placed vertically due to their own weight or shape, conventional CT equipment will expose obvious application shortcomings. Especially for ultra-large workpieces (outer diameter ≥ 1500mm), the existing equipment has rigid bottlenecks in motion stroke, bearing fixtures, and X-ray penetration coverage, making it difficult to meet the CT inspection requirements of ultra-large workpieces. Summary of the Invention

[0003] Based on the above analysis, the present invention aims to provide a high-energy industrial CT system with a composite scanning mode to solve one of the problems of existing technologies that are difficult to meet the CT inspection requirements of ultra-large workpieces, the center of gravity of the equipment is prone to deviate from the rotation axis during rotational scanning, and the CT inspection efficiency of ultra-large workpieces is not high.

[0004] The objective of this invention is mainly achieved through the following technical solutions: A high-energy industrial CT system with a composite scanning mode is characterized by comprising a scanning unit, a transport unit, and a carrier plate. The scanning unit is used to perform central scanning or offset scanning on a workpiece. The carrier plate is used to carry the workpiece and is located on the transport unit. The transport unit is used to transport the carrier plate carrying the workpiece to the scanning unit, so that the workpiece passes through the scanning area of ​​the scanning unit for CT inspection of the workpiece.

[0005] Furthermore, the scanning unit includes a base, a rotating bracket, a rotating drive assembly, and a scanning assembly.

[0006] Furthermore, the scanning assembly is mounted on a rotating bracket, the rotating bracket is rotatably mounted on a base, and the rotation drive assembly is mounted on the base and connected to the rotating bracket.

[0007] Furthermore, the conveying unit includes a first conveying assembly and a second conveying assembly.

[0008] Furthermore, the first and second input assemblies are located on either side of the scanning unit.

[0009] Furthermore, the first conveyor assembly and the second conveyor assembly are arranged opposite each other along the conveying direction of the workpiece.

[0010] Furthermore, the first conveying assembly includes a first conveying drive motor and a first conveying device.

[0011] Furthermore, the first conveyor drive motor is connected to the first conveyor device via a transmission connection.

[0012] Furthermore, the second conveyor assembly includes a second conveyor drive motor and a second conveyor device.

[0013] Furthermore, the second conveyor drive motor is connected to the second conveyor device via a transmission connection.

[0014] The technical solution of this invention can achieve at least one of the following effects: (1) This invention provides a high-energy industrial CT system with a composite scanning mode, comprising a scanning unit, a transport unit, and a carrier plate. The scanning unit is used to perform central scanning or offset scanning on the workpiece; the carrier plate is used to carry the workpiece and is located on the transport unit; the transport unit is used to transport the carrier plate carrying the workpiece to the scanning unit, allowing the workpiece to pass through the scanning area of ​​the scanning unit for CT inspection. This invention enables flexible selection of central scanning or offset scanning mode according to the specific size of the workpiece, thereby meeting the CT inspection requirements of ultra-large workpieces.

[0015] (2) The scanning unit of the present invention includes a center of gravity adjustment assembly, which is used to adjust the center of gravity position of the scanning unit so that the center of gravity of the scanning unit is always located on the rotation axis of the scanning unit when performing center scanning or offset scanning on the workpiece. In other words, the center of gravity of the scanning unit is always located on the rotation axis of the rotating support, thereby reducing the eccentric torque during the rotation process, reducing the jitter and resonance of the scanning unit during rotation, and improving the scanning imaging quality.

[0016] (3) The high-energy industrial CT system of the composite scanning mode of the present invention also includes a loading and unloading unit. Multiple carrier plates are installed on the loading and unloading unit. The loading and unloading unit has a loading station, a scanning station, an unloading station and a waiting station. The loading and unloading unit is used to drive the carrier plates to circulate between the loading station, the scanning station, the unloading station and the waiting station, breaking the traditional single-process serial operation mode, realizing multi-station parallel operation, and eliminating the need to wait for the scanning operation to be completed before loading and / or unloading operations can be performed, thereby greatly shortening the detection cycle, realizing efficient and continuous CT detection of ultra-large workpieces, and improving CT detection efficiency.

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0022] Example 1 To address the limitation of existing technologies in meeting the CT inspection requirements of ultra-large workpieces (outer diameter ≥ 1500 mm), a specific embodiment of this invention discloses a high-energy industrial CT system with a composite scanning mode, such as... Figure 1 As shown, the device includes a scanning unit 1, a transport unit 2, and a carrier plate 3. The scanning unit 1 is used to perform center scanning or offset scanning on the workpiece 100. The carrier plate 3 is used to carry the workpiece 100. The carrier plate 3 is located on the transport unit 2, which can transport the workpiece 100 to the scanning unit 1 and make the workpiece 100 pass through the scanning area of ​​the scanning unit 1 for CT detection of the workpiece 100. Compared with the prior art, this embodiment can flexibly select the center scanning or offset scanning mode according to the specific size of the workpiece 100, thereby adapting to the CT detection requirements of ultra-large workpieces 100.

[0023] Furthermore, such as Figure 2 As shown, the scanning unit 1 includes a base 11, a rotating bracket 12, a rotating drive assembly 13, and a scanning assembly 14. The scanning assembly 14 is mounted on the rotating bracket 12, and the rotating bracket 12 is rotatably mounted on the base 11. The rotating drive assembly 13 is mounted on the base 11 and connected to the rotating bracket 12 to drive the rotating bracket 12 to rotate the scanning assembly 14 around the workpiece 100, and cooperates with the transport unit 2 to perform spiral CT scanning on the workpiece 100.

[0024] Furthermore, the rotary drive assembly 13 adopts a mature rotary drive assembly in the prior art, and this embodiment does not limit the rotary drive assembly 13.

[0025] Furthermore, such as Figure 3 As shown, the scanning assembly 14 includes a radiation source device 141 and a detector device 142. Both the radiation source device 141 and the detector device 142 are slidably mounted on the rotating bracket 12, and the positional relationship between the center beams of the radiation source device 141 and the detector device 142 and the rotation axis of the rotating bracket 12 can be adjusted. When the center beams of the radiation source device 141 and the detector device 142 intersect the rotation axis of the rotating bracket 12, the workpiece 100 is centrally scanned; when the center beams of the radiation source device 141 and the detector device 142 deviate from the rotation axis of the rotating bracket 12, the workpiece 100 is offsetly scanned. This allows for flexible switching between central scanning and offset scanning modes by adjusting the position of the radiation source device 141 and the detector device 142 on the rotating bracket 12 according to the specific size of the workpiece 100, thereby meeting the needs of scanning ultra-large workpieces 100 of different specifications.

[0026] Furthermore, the X-ray source device 141 includes a X-ray source body 1411, a first slide block 1412, a first guide rail 1413, a first drive motor 1414, and a first transmission screw. The X-ray source body 1411 is fixedly mounted on the first slide block 1412, the first slide block 1412 is slidably mounted on the first guide rail 1413, the first guide rail 1413 is fixedly mounted on the rotating bracket 12, the first transmission screw is rotatably mounted on the rotating bracket 12 and threadedly connected to the first slide block 1412, the first drive motor 1414 is mounted on the rotating bracket 12 and connected to the first transmission screw. The first drive motor 1414 drives the first transmission screw to rotate, thereby causing the first slide block 1412 to slide along the first guide rail 1413, and then causing the X-ray source body 1411 to move on the rotating bracket 12, realizing precise and stable displacement adjustment of the X-ray source body 1411 and improving the accuracy of scanning mode switching.

[0027] Furthermore, the detector device 142 includes a detector body 1421, a second slide block 1422, a second guide rail 1423, a second drive motor 1424, and a second transmission screw. The detector body 1421 is fixedly mounted on the second slide block 1422, the second slide block 1422 is slidably mounted on the second guide rail 1423, the second guide rail 1423 is fixedly mounted on the rotating bracket 12, the second transmission screw is rotatably mounted on the rotating bracket 12 and threadedly connected to the second slide block 1422, the second drive motor 1424 is mounted on the rotating bracket 12 and connected to the second transmission screw. The second drive motor 1424 drives the second transmission screw to rotate, thereby causing the second slide block 1422 to slide along the second guide rail 1423, and thus causing the detector body 1421 to move on the rotating bracket 12, realizing precise and stable displacement adjustment of the detector body 1421 and improving the accuracy of scanning mode switching.

[0028] Furthermore, through the coordinated control of the first drive motor 1414 and the second drive motor 1424, the positions of the X-ray source body 1411 and the detector body 1421 on the rotating bracket 12 are adjusted in a coordinated manner. This allows for the adjustment of the positional relationship between the central beam of the X-ray source body 1411 and the detector body 1421 and the rotation axis of the rotating bracket 12 according to the size of the workpiece 100 and the scanning requirements. This enables flexible switching of scanning modes to accurately match different scanning conditions, improves the alignment accuracy between the beam and the detector, and enhances the scanning imaging quality and detection accuracy.

[0029] Furthermore, such as Figure 4 As shown, the bearing plate 3 is provided with a first limiting guide groove 31 and a rack 32, with the rack 32 disposed in the first limiting guide groove 31.

[0030] Furthermore, such as Figure 5As shown, the conveying unit 2 includes a first conveying assembly 21 and a second conveying assembly 22. The first conveying assembly 21 and the second conveying assembly 22 are located on both sides of the scanning unit 1, and the first conveying assembly 21 and the second conveying assembly 22 are arranged opposite to each other along the conveying direction of the workpiece 100. The first conveying assembly 21 and the second conveying assembly 22 work together to convey the workpiece 100 to the scanning area of ​​the scanning unit 1 or remove it from the scanning area of ​​the scanning unit 1.

[0031] Furthermore, to address the issue of insufficient stability during workpiece transport, the first transport assembly 21 includes a first transport drive motor 211 and a first transport device 212. Two first transport devices 212 are provided and arranged side-by-side, enabling them to connect synchronously with the carrier plate 3. The first transport drive motor 211 is connected to the two first transport devices 212, driving them to operate synchronously and thus moving the carrier plate 3 along the transport direction. The synchronous transmission of the two first transport devices 212 ensures that the carrier plate 3 experiences uniform force at multiple points when connected to the two first transport devices 212, improving the stability of the carrier plate 3 during transport, reducing tilting and shaking during workpiece transport, and ultimately improving the scanning imaging quality.

[0032] Furthermore, such as Figure 6 As shown, the first conveying device 212 includes a first frame 2121 and a first conveying assembly 2122. The first conveying drive motor 211 is mounted on the first frame 2121. The first conveying assembly 2122 includes a first gear frame 21221, a first drive gear 21222, and a first drive screw 21223. The first gear frame 21221 is mounted on the first frame 2121. The first drive gear 21222 is rotatably mounted on the first gear frame 21221 and can mesh with the rack 32. The first drive screw 21223 is rotatably mounted on the first gear frame 21221 and meshes with the first drive gear 21222. One end of the first drive screw 21223 is connected to the first conveying drive motor 211. The first drive screw 21223 is driven to rotate by the first conveying drive motor 211, thereby driving the first drive gear 21222 to rotate, thereby driving the bearing plate 3 to move along the conveying direction, thus realizing the smooth conveying of the workpiece 100.

[0033] Furthermore, the first gear frame 21221 can be engaged in the first limiting guide groove 31 to guide and limit the bearing plate 3, so as to prevent the bearing plate 3 from shifting or shaking during movement, thereby further improving the stability of the conveying workpiece 100.

[0034] Furthermore, to address the issue of insufficient stability during further workpiece transport, the second transport assembly 22 includes a second transport drive motor 221 and a second transport device 222. Two second transport devices 222 are provided and arranged side-by-side, enabling them to connect synchronously with the carrier plate 3. The second transport drive motor 221 is connected to the two second transport devices 222 via a transmission connection. The first transport drive motor 211 drives the two second transport devices 222 to operate synchronously, thereby driving the carrier plate 3 to move along the transport direction. Through the synchronous transmission of the two second transport devices 222, the carrier plate 3 is subjected to uniform force at multiple points when connected to the two second transport devices 222, improving the stability of the carrier plate 3 transport, reducing tilting and shaking during workpiece transport, and thus improving the scanning imaging quality.

[0035] Furthermore, the second conveying device 222 includes a second frame 2221 and a second conveying assembly 2222. The second conveying drive motor 221 is mounted on the second frame 2221. The second conveying assembly 2222 includes a second gear frame 22221, a second drive gear 22222, and a second drive screw 22223. The second gear frame 22221 is mounted on the second frame 2221. The second drive gear 22222 is rotatably mounted on the second gear frame 22221 and can mesh with the rack 32. The second drive screw 22223 is rotatably mounted on the second gear frame 22221 and meshes with the second drive gear 22222. One end of the second drive screw 22223 is connected to the second conveying drive motor 221. The second drive screw 22223 is driven to rotate by the second conveying drive motor 221, thereby driving the second drive gear 22222 to rotate, thereby driving the bearing plate 3 to move along the conveying direction, thus realizing the smooth conveying of the workpiece 100.

[0036] Furthermore, the second gear frame 22221 can be engaged in the first limiting guide groove 31 to guide and limit the bearing plate 3, so as to prevent the bearing plate 3 from shifting or shaking during movement, thereby further improving the stability of the conveying workpiece 100.

[0037] Example 2 To address the issue of the device's center of gravity easily deviating from the rotation axis during rotary scanning, Embodiment 2 is a further improvement upon Embodiment 1, such as... Figure 2As shown, the scanning unit 1 includes a center of gravity adjustment assembly 15, which is mounted on the rotating bracket 12. The center of gravity adjustment assembly 15 is used to adjust the center of gravity position of the scanning unit 1. When performing center scanning or offset scanning on the workpiece 100, the center of gravity of the scanning unit 1 is always located on the rotation axis of the scanning unit 1, that is, the center of gravity of the scanning unit 1 is always located on the rotation axis of the rotating bracket 12. This reduces the eccentric torque during rotation, reduces the jitter and resonance of the scanning unit 1 during rotation, and improves the scanning imaging quality. In addition, it can also reduce the impact load on the rotating components and driving components in the scanning unit 1, reduce wear, and extend service life.

[0038] Furthermore, the center of gravity adjustment assembly 15 includes a counterweight 151, a third slide 152, a third guide rail, a third drive motor 153, and a third transmission screw. The counterweight 151 is fixedly mounted on the third slide 152, the third slide 152 is slidably mounted on the third guide rail, the third guide rail is fixedly mounted on the rotating bracket 12, the third transmission screw is rotatably mounted on the rotating bracket 12 and threadedly connected to the third slide 152, and the third drive motor 153 is mounted on the rotating bracket 12 and connected to the third transmission screw, driving the third drive motor 153. The rotation of the third transmission screw drives the third slide block 152 to slide along the third guide rail, thereby moving the counterweight block 151 on the rotating bracket 12. This adjusts the position of the counterweight block 151 on the rotating bracket 12, accurately compensating for the center of gravity shift caused by the positional changes of the X-ray source body 1411 and the detector body 1421. This ensures that the center of gravity of the scanning unit 1 is always located on the rotation axis of the rotating bracket 12, accurately adapting to various scanning offset conditions. This reduces the eccentric torque during rotation, lowers the jitter and resonance of the scanning unit 1 during rotation, and improves the scanning imaging quality.

[0039] Example 3 In existing technologies, when performing CT inspection on ultra-large workpieces, the workpiece 100 is typically fixed to a support plate 3 in a safe area, and then the support plate 3 carrying the workpiece 100 is hoisted onto the transport unit 2 by an overhead crane to complete the loading operation. Then, the transport unit 2 and scanning unit 1 are started, and the workpiece 100 is transported to the scanning area of ​​the scanning unit 1 by the transport unit 2 for scanning. After scanning, the support plate 3 carrying the workpiece 100 is removed from the scanning area of ​​the scanning unit 1 by the transport unit 2 to complete the scanning operation of the workpiece 100. Then, the transport unit 2 and scanning unit 1 are shut down, and the support plate 3 carrying the workpiece 100 is hoisted off the transport unit 2 to a safe area by an overhead crane, where the workpiece 100 is unloaded from the support plate 3 to complete the unloading operation. This process is cumbersome and requires multiple start-ups and shutdowns of the equipment, resulting in low CT inspection efficiency. Therefore, to solve the problem of low CT inspection efficiency for ultra-large workpieces in existing technologies, Embodiment 3 is a further improvement based on Embodiment 1 or Embodiment 2, such as... Figure 7 As shown, the high-energy industrial CT system with composite scanning mode also includes a loading and unloading unit 4. Multiple carrier plates 3 are installed on the loading and unloading unit 4. The loading and unloading unit 4 has a loading station, a scanning station, an unloading station, and a waiting station. The loading and unloading unit 4 is used to drive the carrier plates 3 to circulate between the loading station, the scanning station, the unloading station, and the waiting station, so as to realize multi-station parallel operation, break the traditional single-process serial operation mode, and eliminate the need to wait for the scanning operation to be completed before loading and / or unloading operations can be performed, thereby greatly shortening the detection cycle and realizing efficient and continuous CT detection of ultra-large workpieces 100, thus improving CT detection efficiency.

[0040] Specifically, the loading / unloading unit 4 moves the carrier plate 3 from the waiting station to the loading station. The carrier plate 3 at the loading station is in a safe area, where the operator loads the workpiece 100 onto the carrier plate 3, completing the loading operation. The loading / unloading unit 4 then moves the carrier plate 3 to the scanning station. The carrier plate 3 at the scanning station can be separated from or connected to the loading / unloading unit 4, and can also be connected to or separated from the conveying unit 2. Specifically, after being separated from the loading / unloading unit 4, the carrier plate 3 is connected to the conveying unit 2. The conveying unit 2 transports the carrier plate 3 carrying the workpiece 100 to the scanning area of ​​the scanning unit 1 for scanning. After scanning, the conveying unit 2 removes the carrier plate 3 carrying the workpiece 100 from the scanning area of ​​the scanning unit 1. The system separates the support plate 3 carrying the workpiece 100 from the transport unit 2 and reconnects it to the loading and unloading unit 4. The loading and unloading unit 4 then moves the support plate 3 to the unloading station. The support plate 3 at the unloading station is in a safe area where the operator unloads the workpiece 100 from the support plate 3, completing the unloading operation. The loading and unloading unit 4 then moves the support plate 3 to the waiting station. This breaks the traditional single-process serial operation mode, enabling parallel processing of CT scanning, loading, and unloading operations. There is no need to wait for the scanning operation to be completed before loading and / or unloading operations can be performed, thus significantly shortening the single inspection cycle and achieving efficient and continuous CT scanning inspection of large or ultra-large workpieces, thereby improving inspection efficiency.

[0041] Furthermore, the first conveying assembly 2122 is slidably mounted on the first frame 2121, thereby protruding or retracting into the first frame 2121. When the first conveying assembly 2122 retracts into the first frame 2121, the first drive gear 21222 separates from the rack 32, and the support plate 3 is disconnected from the conveying unit 2. At this time, the first conveying assembly 2122 will not interfere with the movement of the support plate 3, making it easier for the loading and unloading unit 4 to drive the support plate 3 to move. When the first conveying assembly 2122 protrudes from the first frame 2121, the first drive gear 21222 meshes with the rack 32, and the support plate 3 establishes a power connection with the conveying unit 2, which drives the support plate 3 into the scanning area. In addition, when the first conveying assembly 2122 protrudes from the first frame 2121, the first gear frame 21221 engages with the first limiting guide groove 31 to laterally limit the support plate 3, preventing it from shifting or shaking during scanning and improving scanning stability.

[0042] Furthermore, to address the issue of insufficient stability in the continuous power transmission during workpiece conveying, the first conveying assembly 21 further includes a gear post 213 and a transition gear 214. Both the gear post 213 and the transition gear 214 are mounted on the first frame 2121. The transition gear 214 meshes with the first drive screw 21223 and simultaneously with the gear post 213, and can move axially along the gear post 213. One end of the gear post 213 is connected to the first conveying drive motor 211, thereby ensuring that the power of the first conveying drive motor 211 can always be transmitted to the first drive screw 21223, improving the continuity and stability of power transmission.

[0043] Furthermore, to address the issue of insufficient continuity in the operation of the carrier plate at the scanning station, the loading and unloading unit 4 includes a transposition assembly 41, a transposition drive assembly 42, and a linkage assembly 43. The linkage assembly 43 is mounted on the first frame 2121 and connected to the first conveyor assembly 2122. The linkage assembly 43 can also be driven by the transposition assembly 41 and the carrier plate 3, thereby accurately controlling the first conveyor assembly 2122 to protrude or retract into the first frame 2121 according to the timing of the actions of the transposition assembly 41 and the carrier plate 3. The first conveyor assembly 2122 is used to carry the carrier plate 3. The shift drive assembly 42 is connected to the shift assembly 41 and is used to drive the shift assembly 41 to operate, thereby enabling the carrier plate 3 to be smoothly switched and accurately positioned between various workstations. The linkage assembly 43 can accurately control the first conveyor assembly 2122 to protrude or retract into the first frame 2121 according to the action sequence of the shift assembly 41 and the carrier plate 3, thereby realizing the orderly disengagement and reconnection of the carrier plate 3 between the shift assembly 41 and the shift drive assembly 42, improving the continuity of the scanning workstation operation.

[0044] Furthermore, to address the issue of insufficient smoothness in the switching of the carrier plate 3 between different workstations, the transposition assembly 41 includes a first carrying device and a second carrying device. The first and second carrying devices have identical structures and are symmetrically arranged on both sides of the conveying unit 2. The transposition drive assembly 42 includes a transposition drive motor 421 and a transmission shaft 422. The transposition drive motor 421 is mounted on the first carrying device. The output shaft of the transposition drive motor 421 is connected to the transmission shaft 422, and the transmission shaft 422 is connected to the first and second carrying devices via a transmission connection. The motor 421 drives the transmission shaft 422 to rotate, thereby driving the first carrying device and the second carrying device to operate synchronously, realizing the smooth switching and precise positioning of the bearing plate 3 between each workstation. The first carrying device and the second carrying device are symmetrically arranged on both sides of the conveying unit 2. The first carrying device and the second carrying device jointly carry the bearing plate 3, thereby making the bearing plate 3 subject to balanced force, suppressing the offset tendency caused by unilateral force when the bearing plate 3 switches between each workstation, reducing the risk of offset or shaking, and thus improving the smoothness of the bearing plate 3 switching between each workstation.

[0045] Furthermore, such as Figure 8 and Figure 9 As shown, both the first and second carrying devices include a carrying mechanism 411 and a carrying block 412. The carrying block 412 can be connected to the support plate 3. Multiple carrying blocks 412 are provided, each corresponding to one of the support plates 3. The carrying mechanism 411 includes a support shell 4111, a driving gear 4112, a driven gear 4113, and a chain 4114. The driving gear 4112 and the driven gear 4113 are rotatably mounted in the support shell 4111, and the driving gear 4112 and the driven gear 4113 are connected by the chain 4114. The support shell 4111 is provided with a second limiting guide groove 41111. The carrying block 412 is installed in the second limiting guide groove 41111 and is fixedly connected to the chain 4114. The transmission shaft 422 is connected to the drive gear 4112. The drive gear 4112 is driven to rotate by the shift drive motor 421, which in turn drives the carrying block 412 to move along the second limiting guide groove 41111 in the support shell 4111 through the chain 4114. This drives the carrier plate 3 to move, so as to realize the smooth switching and precise positioning of the carrier plate 3 between various work stations.

[0046] Furthermore, the carrying block 412 is also provided with a slot, and the bearing plate 3 is also provided with a locking block 33. The locking block 33 can be locked into or slide out of the slot. When the locking block 33 slides out of the slot, the bearing plate 3 is disengaged from the carrying block 412 so that the bearing plate 3 can be connected to the conveying unit 2, thereby realizing the separation of the bearing plate 3 from the loading and unloading unit 4 and the connection with the conveying unit 2. When the locking block 33 is locked into the slot, the bearing plate 3 is connected to the carrying block 412, thereby realizing the separation of the bearing plate 3 from the conveying unit 2 and the reconnection with the loading and unloading unit 4, thereby realizing the loading and unloading unit 4 driving the bearing plate 3 to move between each workstation.

[0047] It should be noted that the power for the card block 33 to engage or disengage from the card slot is provided by the conveying unit 2.

[0048] Furthermore, the slot is an arc-shaped slot structure, and the block 33 is an arc-shaped block structure that matches the slot, thereby preventing the bearing plate 3 from shifting laterally or falling off accidentally during the movement of the carrier block 412, improving the stability of the connection between the bearing plate 3 and the carrier block 412, and improving the connection stability between the bearing plate 3 and the carrier block 412 during the repositioning process.

[0049] Furthermore, a locking spring (not shown in the figure) is provided in the slot. The locking spring can undergo elastic deformation and generate pre-tightening force when the card block 33 is inserted into the slot, so as to enhance the connection between the card block 33 and the slot and prevent the carrier plate 3 and the carrier block 412 from loosening or disengaging during the repositioning process, thereby further improving the stability and reliability of the carrier plate 3 during the repositioning process.

[0050] Furthermore, the locking spring is made of rubber or polyurethane material.

[0051] Furthermore, the carrying block 412 in the first carrying device is also provided with a positioning block (not shown in the figure). The positioning block is set in the slot and is used to brake the carrying plate 3 when the carrying plate 3 is inserted into the slot and reaches a specific position (i.e., the position after the carrying plate 3 carries the workpiece 100 to complete the scanning and reset). It also works with the locking spring to ensure the positioning accuracy and connection stability of the carrying plate 3 after it is in place.

[0052] Furthermore, the first frame 2121 is fixedly connected to the support shell 4111 in the first carrying device and / or the second carrying device.

[0053] Furthermore, in order to further address the issue of insufficient continuity of the carrier plate 3 during scanning operations, such as... Figure 10As shown, the linkage assembly 43 includes a linkage execution device 431 and a reset device 432. The linkage execution device 431 is mounted on the first frame 2121 and connected to the first conveying assembly 2122. The linkage execution device 431 can also be connected to the carrying block 412 in the first carrying device. When the carrying block 412 moves to the scanning station, the linkage execution device 431 drives the first conveying assembly 2122 to protrude from the first frame 2121, realizing the power connection between the carrier plate 3 and the conveying unit 2. The reset device 432 is mounted on... The linkage execution device 431 can be connected to the carrier plate 3 during the reset process to drive the linkage execution device 431 to reset, thereby driving the first conveying component 2122 to reset and retract the first conveying component 2122 into the first frame 2121, realizing the power separation between the carrier plate 3 and the conveying unit 2. This achieves the automatic connection and separation between the carrier plate 3 and the conveying unit 2 at the scanning station, as well as the automatic separation and reconnection between the carrier plate 3 and the loading and unloading unit 4, thereby improving the continuity of the scanning station operation.

[0054] Furthermore, the linkage actuator 431 includes a linkage rail 4311, a limiting sleeve 4312, a first linkage rod 4313, a linkage spring 4314, a second linkage rod 4315, a position lock 4316, a linkage slide plate 4317, and a third linkage rod 4318. The linkage rail 4311 is fixedly installed on the carrying block 412 in the first carrying device, and the limiting sleeve 4312 is fixedly installed on the first frame 2121. The first linkage rod 4313, the linkage spring 4314, and the second linkage rod 4315 are all slidably disposed within the limiting sleeve 4312, and the first linkage rod 4313, the linkage spring 4314, and the second linkage rod 4318 are all slidably disposed within the limiting sleeve 4312. Linkage rods 4315 are fixedly connected in sequence; position lock 4316 is installed on limit sleeve 4312 to lock the second linkage rod 4315 so that the second linkage rod 4315 can be locked in the first position or the second position; one end of the first linkage rod 4313 can abut against the linkage rail 4311; one end of the second linkage rod 4315 is fixedly connected to the linkage slide plate 4317; the linkage slide plate 4317 is slidably installed on the first frame 2121 and can slide along the length direction of the first frame 2121; both ends of the third linkage rod 4318 are hinged to the linkage slide plate 4317 and the first gear frame 21221 respectively; Specifically, when the carrier block 412 moves from the loading station to the scanning station, one end of the first linkage rod 4313 can abut against the linkage rail 4311 and slide under pressure. At this time, the position lock 4316 stably locks the second linkage rod 4315 in the first position, and the linkage spring 4314 is compressed and stores energy synchronously with the sliding of the first linkage rod 4313. After the carrier block 412 moves to the scanning station, the linkage spring 4314 is compressed to the preset energy storage state. At this time, the elastic force of the linkage spring 4314 can overcome the first position locking constraint force of the position lock 4316, push the second linkage rod 4315 to slide smoothly to the second position, and the position lock 4316 completes the second position locking and positioning. During this process, the movement of the second linkage rod 4315 drives the linkage slide plate 4317 to slide along the length direction of the first frame 2121, and then pushes the third linkage rod 4318. The first gear frame 21221 moves, causing the first gear frame 21221 and the first drive gear 21222 to protrude synchronously from the first frame 2121. During the protrusion process, the first gear frame 21221 precisely engages with the first limiting guide groove 31, completing the lateral limiting correction of the support plate 3. At the same time, the first drive gear 21222 precisely meshes with the rack 32 of the support plate 3, stably establishing a power connection between the conveying unit 2 and the support plate 3. Subsequently, the conveying unit 2 can drive the support plate 3 to carry the workpiece 100 smoothly into the scanning area to complete the scanning operation. Thus, after the support plate 3 is in place at the scanning station, it can automatically complete the precise docking and power coupling with the conveying unit 2, as well as the automatic separation from the loading and unloading unit 4. This makes the timing of the action of conveying the workpiece 100 to the scanning area of ​​the scanning unit 1 precise and continuous, thereby improving the orderliness and continuity of the scanning station operation.

[0055] Furthermore, such as Figure 11As shown, to address the reliability issue of insufficient dynamic coupling between the conveying unit and the carrier plate, the position lock 4316 includes a first magnetic block 43161, a second magnetic block 43162, and a third magnetic block 43163. The first magnetic block 43161 and the second magnetic block 43162 are fixedly mounted on the second linkage rod 4315, and the distance between the first magnetic block 43161 and the second magnetic block 43162 precisely matches the first and second position strokes of the second linkage rod 4315. The third magnetic block 43163 is fixedly mounted on the limiting sleeve 4312. When the second linkage rod 431... When the second linkage rod 4315 is in the first position, the first magnetic block 43161 and the third magnetic block 43163 magnetically attract each other, locking the second linkage rod 4315 in the first position; when the second linkage rod 4315 moves to the second position, the second magnetic block 43162 and the third magnetic block 43163 magnetically attract each other, locking the second linkage rod 4315 in the second position, thereby achieving precise positioning and reliable locking of the second linkage rod 4315 in the first and second positions, thereby achieving stable holding of the first conveying component assembly 2122 in the protruding or retracted state, and improving the reliability of the dynamic coupling between the conveying unit and the bearing plate.

[0056] Furthermore, such as Figure 12 As shown, the reset device 432 includes a reset sliding sleeve 4321, a support rod 4322, a reset connecting plate 4323, and a reset driving plate 4324. The reset sliding sleeve 4321 is sleeved on the limiting sleeve 4312 and can slide along the axial direction of the limiting sleeve 4312. The reset sliding sleeve 4321 can also be fixedly connected to the middle part of the linkage spring 4314 through the clearance hole on the limiting sleeve 4312, thereby dividing the linkage spring 4314 into a first spring segment and a second spring segment. One end of the support rod 4322 is fixedly connected to the reset sliding sleeve 4321, and the other end is connected to the reset connecting plate 4323. The reset driving plate 4324 is fixedly installed on the locking block 33 corresponding to the first carrying device and can move synchronously with the locking block 33. Specifically, when the carrier block 412 moves from the loading station to the scanning station, one end of the first linkage rod 4313 can abut against the linkage rail 4311 and slide under pressure. At this time, the position lock 4316 locks the second linkage rod 4315 in the first position, the linkage spring 4314 is compressed, and the reset sleeve 4321 slides synchronously along the axial direction of the limiting sleeve 4312, thereby driving the reset connecting plate 4323 to move synchronously. The reset connecting plate 4323 and the reset drive plate 4324 are misaligned and do not interfere. After the carrier block 412 moves to the scanning station and is in place, a power connection is established between the conveying unit 2 and the bearing plate 3, driving the bearing plate 3 to carry the workpiece 100 to the scanning area of ​​the scanning unit 1. During this process, the reset... The position drive plate 4324 slides smoothly with the support plate 3, while the reset connecting plate 4323 avoids it in one direction. The reset drive plate 4324 passes through the reset connecting plate 4323 without any structural interference, and the reset drive plate 4324 and the reset connecting plate 4323 are not connected. After scanning, the input unit 2 continues to work. When the drive support plate 3 moves out of the scanning area to reset, the reset drive plate 4324 moves in the opposite direction with the support plate 3, forming rigid interference with the reset connecting plate 4323, so that the reset connecting plate 4323 and the reset drive plate 4324 are connected, thereby pushing the reset connecting plate 4323 and the reset sliding sleeve 4321 to slide axially synchronously. Since the position locker 4316 locks the second linkage rod 4315 in the second position, the linkage spring 4324 is thus activated. In section 314, the first spring segment compresses and stores energy, while the second spring segment extends and stores energy. After the bearing plate 3 returns to its reset position, the second spring segment is stretched to a preset energy storage state. At this time, the elastic force of the second spring segment overcomes the constraint force applied by the position lock 4316 to the second linkage rod 4315. Under the action of the elastic force, the second linkage rod 4315 moves to the first position and is locked again by the position lock 4316. Simultaneously, it drives the first conveying assembly 2122 to retract into the first frame 2121. The bearing plate 3 and the conveying unit 2 complete the power separation, and the bearing plate 3 and the loading and unloading unit 4 reconnect. The loading and unloading unit 4 drives the bearing plate 3 to move towards the unloading station. At this time, the reset drive plate 4324 moves relative to the reset connecting plate 4323, but the reset connection... The connecting plate 4323 remains connected to the reset drive plate 4324, and the reset sleeve 4321 remains in the axial position on the limiting sleeve 4312, thereby keeping the first spring segment in a compressed state. This keeps the first linkage rod 4313 in contact with the linkage rail 4311 until the loading and unloading unit 4 drives the bearing plate 3 completely away from the scanning station. At this point, the first linkage rod 4313 resets, and the reset connecting plate 4323 disengages from the reset drive plate 4324. This allows the automatic separation of the bearing plate 3 from the conveying unit 2 and the reconnection with the loading and unloading unit 4 when the workpiece moves out of the scanning area of ​​the scanning unit 1 and returns to the initial position. This improves the orderliness and continuity of the scanning station operation. Further, the reset connecting plate 4323 includes a fixed plate 43231, a movable plate 43232, and a reset torsion spring (not shown in the figure). The fixed plate 43231 is fixedly mounted on the support rod 4322, and the movable plate 43232 is rotatably connected to the fixed plate 43231 through the reset torsion spring. When the drive bearing plate 3 carries the workpiece 100 to the scanning area of ​​the scanning unit 1, the reset drive plate 4324 moves with the latch 33. After the reset drive plate 4324 contacts the movable plate 43232, it pushes the movable plate 43232 to rotate, thereby avoiding the movement of the reset drive plate 4324, so that the reset drive plate 4324 passes over the reset connecting plate 4323 without connecting with the reset connecting plate 4323. After connecting plate 4323, under the action of reset torsion spring, movable plate 43232 rotates and resets; when the workpiece 100 carried by drive bearing plate 3 returns from the scanning area of ​​scanning unit 1 and resets, reset drive plate 4324 moves in the opposite direction with block 33, and reset drive plate 4324 contacts movable plate 43232. Since movable plate 43232 has rotated and reset, it can no longer avoid the workpiece, and reset drive plate 4324 rigidly interferes with movable plate 43232, thereby connecting reset connecting plate 4323 with reset drive plate 4324, and then pushing reset connecting plate 4323 to move, which in turn drives reset sliding sleeve 4321 to slide in the opposite direction along the axial direction of limit sleeve 4312, realizing unidirectional avoidance and reverse locking connection, so that the equipment operation is orderly and cyclical.
