Description

Technical Field

[0001] This invention relates to the field of vehicle body VIN code imprinting technology, and more particularly to a vehicle body VIN code imprinting device. Background Technology

[0002] The Vehicle Identification Number (VIN) contains information such as the vehicle's manufacturer, year of manufacture, model, body style and code, engine code, and assembly location. It is crucial for accurately identifying the vehicle model and for proper diagnosis and repair. The VIN is typically printed on the lower edge of the right-side B-pillar. Two VINs are printed on each vehicle at the factory as part of the vehicle's documentation for subsequent registration and licensing.

[0003] In existing technology, a robot is used to bring the printing device to the right side of the vehicle body for printing. The printing device uses an adsorption plate to hold the printing paper, and then moves the mechanism containing the adsorption plate back and forth to make the printing paper adhere tightly to the vehicle body's VIN code for printing.

[0004] Existing rubbing devices only consider the movement and adjustment of the adsorption plate in the front-to-back direction (vehicle width direction), and the adsorption plate cannot be adjusted by swinging. If the vehicle body is not in the correct posture, the existing adsorption plate will have one end with the rubbing paper attached to the vehicle body, while the other end will not be attached to the vehicle body or may even separate from it, affecting the rubbing effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vehicle body VIN code imprinting device that can adaptively adjust according to the vehicle body posture, so as to improve the imprinting quality.

[0006] The present invention provides a vehicle body VIN code imprinting device, including a connecting fixture for connecting to a mobile device, a sliding seat that is slidably connected to the connecting fixture and can move longitudinally, a swing seat that is mounted on the sliding seat and can swing laterally, and an adsorption imprinting mechanism mounted on the swing seat.

[0007] The adsorption and printing mechanism is used to adsorb printing paper and print the vehicle body VIN code. The front part of the adsorption and printing mechanism has a printing paper adsorption plate extending laterally, and the printing paper adsorption plate has a center point of the printing paper.

[0008] The swing seat is connected to the sliding seat through a swing adjustment mechanism, and the swing center of the swing adjustment mechanism coincides with the center point of the printing paper.

[0009] In one optional technical solution, the swing adjustment mechanism includes two symmetrically arranged multi-link assemblies. Each multi-link assembly is connected to the swing seat by a swing return elastic element. The center point of the printing paper is located on the extension line of the symmetry line of the two multi-link assemblies, and the center point of the printing paper is the swing center of each multi-link assembly. In another optional technical solution, the multi-link assembly includes two spaced-apart first pivot members pivotally connected to the sliding seat and two spaced-apart second pivot members pivotally connected to the swing seat.

[0010] The extended lines connecting the two first pivots and the extended lines connecting the two second pivots intersect at the center point of the printing paper.

[0011] In one of the alternative technical solutions, the multi-link assembly includes a first link, a second link, a third link, and a fourth link. The front ends of the first link and the third link are respectively connected to the sliding seat via the first pivot member. The front ends of the second link and the fourth link are respectively connected to the swing seat via the second pivot member. The second link and the third link are arranged crosswise and pivotally connected. The rear end of the second link is pivotally connected to the rear end of the first link, and the rear end of the third link is pivotally connected to the rear end of the fourth link.

[0012] In one of the alternative technical solutions, a sliding limiting structure for limiting the forward and backward movement of the sliding seat is assembled between the connecting fixture and the sliding seat;

[0013] An actuating elastic element for driving the sliding seat forward is also connected between the connecting fixture and the sliding seat;

[0014] When the actuating elastic element is in its initial state, the sliding seat moves forward to its limit position.

[0015] In one of the alternative technical solutions, a swing locking mechanism is assembled between the sliding seat and the swing seat;

[0016] When the swing locking mechanism is in the swing locking state, the swing seat and the sliding seat remain relatively fixed.

[0017] When the swing locking mechanism is in the swing unlocked state, the swing seat can swing laterally relative to the sliding seat.

[0018] In one of the alternative technical solutions, the swing locking mechanism includes a locking plate with a T-shaped limiting groove, a locking member connected to the sliding seat and clearance-fitted with the T-shaped limiting groove, and a locking plate driving module connected to the swing seat and used to drive the locking plate to move longitudinally.

[0019] The T-shaped limiting groove includes a longitudinal limiting groove and a transverse limiting groove. The locking plate driving module drives the locking plate to move so that the locking member can switch between the longitudinal limiting groove and the transverse limiting groove.

[0020] In one of the alternative technical solutions, the adsorption printing mechanism includes a swing bracket pivotally connected to the swing seat and a bracket drive module for driving the swing bracket to swing up and down.

[0021] The swing bracket is provided with two printing paper adsorption plates spaced apart, and the two printing paper adsorption plates are arranged in a fan shape relative to the pivot axis of the swing bracket.

[0022] The bracket drive module drives the swing bracket to swing so that the two printing paper adsorption plates can alternately face forward.

[0023] In one of the alternative technical solutions, the adsorption printing mechanism includes a printing motor with a printing rotating head and a multi-directional adjustment drive module for driving the printing motor to perform multi-directional position adjustment relative to the printing paper adsorption plate.

[0024] The printing paper adsorption plate is provided with an adsorption plate opening for the printing rotating head to pass through, and the adsorption plate opening extends laterally.

[0025] When the rubbing paper adsorbs the rubbing paper, the rubbing paper covers the opening of the adsorption plate.

[0026] In one of the alternative technical solutions, the front end face of the printing rotating head is provided with multiple telescopic balls.

[0027] The above technical solution has the following beneficial effects:

[0028] The vehicle body VIN code imprinting device provided by this invention has a sliding seat that can drive the upper swing seat and adsorption imprinting mechanism to move and adjust longitudinally. The swing seat is connected to the sliding seat through a swing adjustment mechanism, so that the adsorption imprinting mechanism can adaptively swing and adjust according to the vehicle body posture, ensuring that the imprinting paper stays in contact with the vehicle body. Moreover, the swing center of the swing adjustment mechanism coincides with the center point of the imprinting paper. When the imprinting paper is in contact with the vehicle body, even if the adsorption imprinting mechanism swings, the imprinting paper will not rub against the vehicle body and will not wrinkle, thus ensuring the flatness of the imprinting paper and improving the imprinting quality.

[0047] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0048] like Figure 1-3 , Figure 6 , Figure 8 , Figure 10 , Figure 13 and Figure 17 As shown, an embodiment of the present invention provides a vehicle body VIN code imprinting device, including a connecting fixture 1 for connecting to a mobile device, a sliding seat 2 that is slidably connected to the connecting fixture 1 and can move longitudinally, a swing seat 3 that is mounted on the sliding seat 2 and can swing laterally, and an adsorption imprinting mechanism 4 that is mounted on the swing seat 3.

[0049] The adsorption and printing mechanism 4 is used to adsorb the printing paper 10 and to print the vehicle body VIN code. The front part of the adsorption and printing mechanism 4 has a printing paper adsorption plate 41 extending laterally, and the printing paper adsorption plate 41 has a printing paper center point O.

[0050] The swing seat 3 is connected to the sliding seat 2 through the swing adjustment mechanism 5, and the swing center of the swing adjustment mechanism 5 coincides with the center point O of the printing paper.

[0051] The vehicle body VIN code imprinting device provided by this invention is mainly used for imprinting the vehicle body VIN code on the side of the vehicle body.

[0052] In this invention, the longitudinal direction refers to the front-to-back direction; when imprinting the VIN code on the vehicle body, this longitudinal direction refers to the vehicle width direction. The lateral direction refers to the left-to-right direction; when imprinting the VIN code on the vehicle body, this longitudinal direction refers to the vehicle length direction.

[0053] The vehicle body VIN code imprinting device includes a connecting fixture 1, a sliding seat 2, a swing seat 3, an adsorption imprinting mechanism 4, and a swing adjustment mechanism 5.

[0054] The connecting fixture 1 is used to connect to a mobile device, which may be a robot. The connecting fixture 1 is installed on the robot's gripper. Specifically, the connecting fixture 1 includes a fixture base plate 11, two fixture side plates 12, and a fixture top plate 13. As needed, the fixture base plate 11 can be arranged at an angle to connect and fix it to the robot's gripper.

[0055] The sliding seat 2 is slidably connected to the connecting fixture 1, and can slide back and forth longitudinally (front and back) relative to the connecting fixture 1. Specifically, the sliding seat 2 is connected to the top plate 13 of the fixture, and a guide structure such as a linear guide rail and a linear groove is assembled between the two.

[0056] The swing seat 3 is mounted on the sliding seat 2 via the swing adjustment mechanism 5, and the swing seat 3 can swing back and forth laterally (left and right) relative to the sliding seat 2. The swing adjustment mechanism 5 can be a multi-link swing adjustment mechanism, etc.

[0057] The sliding seat 2 and the swing seat 3 in this invention can adopt a seat structure, a flat plate structure, a frame structure, etc.

[0058] The adsorption and printing mechanism 4 is mounted on the swing seat 3. The adsorption and printing mechanism 4 can be adjusted to a suitable position on the swing seat 3 to adsorb the printing paper 10 and perform vehicle body VIN code printing. The front of the adsorption and printing mechanism 4 has a printing paper adsorption plate 41, which is used to adsorb the printing paper 10. During printing, the printing paper adsorption plate 41 faces the side of the vehicle body to adhere the printing paper 10 to the side of the vehicle body. The printing paper adsorption plate 41 extends laterally, with adsorption ports 411 at both ends and a printing paper center point O in the middle. The printing paper center point O is the intersection of the center lines of the printing paper 10 along the length and width directions.

[0059] The swing center of the swing adjustment mechanism 5 coincides with the center point O of the printing paper, meaning that the swing adjustment mechanism 5 swings around the center point O of the printing paper. When the swing adjustment mechanism 5 drives the swing plate 3 and the adsorption printing mechanism 4 above to swing, the swing plate 3 and the adsorption printing mechanism 4 also swing around the center point O of the printing paper. The center point O of the printing paper is stationary relative to the swing adjustment mechanism 5, the swing plate 3, and the adsorption printing mechanism 4. During the rubbing process, the rubbing paper 10 contacts the side of the vehicle body. If the vehicle body is tilted, the rubbing paper adsorption plate 41 is subjected to the reaction force of the tilt during the forward movement of the adsorption rubbing mechanism 4. This force is transmitted to the swing adjustment mechanism 5 through the adsorption rubbing mechanism 4 and the swing plate 3. The swing adjustment mechanism 5 adjusts itself by swinging adaptively after being subjected to the force. At this time, the swing plate 3 and the adsorption rubbing mechanism 4 also swing accordingly. Throughout the process, the center point O of the rubbing paper does not move. The rubbing paper adsorption plate 41 swings with the rubbing paper 10 only around the center point O of the rubbing paper, without moving relative to the vehicle body. The rubbing paper 10 will not rub against the vehicle body and will not wrinkle, thus ensuring the flatness of the rubbing paper 10 and improving the rubbing quality.

[0060] If necessary, an adaptive adjustment mechanism for adjusting the position of the sliding seat 2 can be installed between the sliding seat 2 and the connecting fixture 1. When the mobile device moves the entire vehicle body VIN code imprinting device toward the side of the vehicle body, the sliding seat 2 is positioned forward on the connecting fixture 1. After the imprinting paper adsorption plate 41, carrying the imprinting paper 10, contacts the side of the vehicle body, under the reaction force, the sliding seat 2 moves backward a certain distance on the connecting fixture 1, so that the imprinting paper adsorption plate 41 presses against the vehicle body to facilitate subsequent imprinting operations.

[0061] The vehicle body VIN code imprinting device provided by the present invention has a sliding seat 2 that can drive the upper swing seat 3 and the adsorption imprinting mechanism 4 to move and adjust longitudinally. The swing seat 3 is connected to the sliding seat 2 through the swing adjustment mechanism 5, so that the imprinting paper adsorption plate 41 can adaptively swing and adjust according to the vehicle body posture, ensuring that the imprinting paper 10 remains in contact with the vehicle body. Moreover, the swing center of the swing adjustment mechanism 5 coincides with the center point O of the imprinting paper. When the imprinting paper 10 is in contact with the vehicle body, even if the imprinting paper adsorption plate 41 swings, the imprinting paper 10 will not rub against the vehicle body and will not wrinkle, thus ensuring the flatness of the imprinting paper 10 and improving the imprinting quality.

[0062] In one embodiment, such as Figure 8 and Figure 10-13 As shown, the swing adjustment mechanism 5 includes two sets of symmetrically arranged multi-link assemblies 51. Each set of multi-link assemblies 51 is connected to the swing seat 3 by a swing reset elastic element 8. The center point O of the rubbing paper is located on the extension line of the symmetry line of the two sets of multi-link assemblies 51, and the center point O of the rubbing paper is the swing center of each set of multi-link assemblies 51.

[0063] In this embodiment, the swing adjustment mechanism 5 adopts two sets of multi-link assemblies 51. The two sets of multi-link assemblies 51 are arranged symmetrically in a straight line passing through the center point O of the printing paper in the longitudinal direction. Each set of multi-link assemblies 51 swings with the center point O of the printing paper as the swing center, ensuring that the swing center of the swing adjustment mechanism 5 coincides with the center point O of the printing paper.

[0064] The swing-reset elastic element 8 is used to drive the multi-link assembly 51 to reset after swinging. The swing-reset elastic element 8 can be a spring, a sheet, etc. Preferably, the two swing-reset elastic elements 8 are arranged symmetrically.

[0065] In one embodiment, such as Figure 8 and Figure 10-13 As shown, the multi-link assembly 51 includes two spaced-apart first pivot members 515 pivotally connected to the sliding seat 2 and two spaced-apart second pivot members 516 pivotally connected to the swing seat 3.

[0066] The extended lines connecting the two first pivots 515 and the extended lines connecting the two second pivots 516 intersect at the center point O of the printing paper.

[0067] In this embodiment, the multi-link assembly 51 includes two first pivot members 515 and two second pivot members 516, with the two second pivot members 516 located on the side of the two first pivot members 515 away from the line of symmetry. The two first pivot members 515 and the two second pivot members 516 are arranged at intervals, front and back, and left and right, with a certain distance between them. The lines connecting the two first pivot members 515 and the two second pivot members 516 are inclined relative to the line of symmetry, and the extension of the line connecting the two first pivot members 515 passes through the center point O of the printing paper, as does the extension of the line connecting the two second pivot members 516, ensuring that the multi-link assembly 51 swings with the center point O of the printing paper as its swing center.

[0068] The pivot component in this invention can be a pivot shaft, on which a bearing can be mounted to reduce friction.

[0069] In one embodiment, such as Figure 8 and Figure 10-13 As shown, the multi-link assembly 51 includes a first link 511, a second link 512, a third link 513, and a fourth link 514. The front ends of the first link 511 and the third link 513 are respectively connected to the sliding seat 2 via a first pivot 515. The front ends of the second link 512 and the fourth link 514 are respectively connected to the swing seat 3 via a second pivot 516. The second link 512 and the third link 513 are arranged crosswise and pivotally connected. The rear end of the second link 512 is pivotally connected to the rear end of the first link 511, and the rear end of the third link 513 is pivotally connected to the rear end of the fourth link 514.

[0070] In this embodiment, the multi-link assembly 51 is a four-link structure, including a first link 511, a second link 512, a third link 513, and a fourth link 514. The front ends of the first link 511 and the third link 513 are each provided with a downwardly extending first pivot member 515, which can be pivotally connected to the sliding seat 2. The front ends of the second link 512 and the fourth link 514 are each provided with a second pivot member 516, which can be pivotally connected to the swing seat 3. The second link 512 and the third link 513 are arranged crosswise, and the second link 512 and the third link 513 are pivotally connected at the middle position via a third pivot member. The rear end of the second link 512 is pivotally connected to the rear end of the first link 511 via a fourth pivot member, and the rear end of the third link 513 is pivotally connected to the rear end of the fourth link 514 via a fifth pivot member.

[0071] During the swing, the multi-link assembly 51 first swings around the center point O of the printing paper as the swing center, while the second link 512 and the third link 513 can swing around the third pivot as the center to open or close, thereby adaptively adjusting the relative position between the swing seat 3 and the sliding seat 2.

[0072] In one embodiment, such as Figure 3-4 , Figure 8 and Figure 14-15 As shown, a sliding limit structure for limiting the forward and backward movement of the sliding seat 2 is assembled between the connecting fixture 1 and the sliding seat 2.

[0073] An actuating elastic element 6 for driving the sliding seat 2 forward is also connected between the connecting fixture 1 and the sliding seat 2.

[0074] When the actuating elastic element 6 is in its initial state, the sliding seat 2 moves forward to its limit position.

[0075] In this embodiment, a sliding limiting structure is assembled between the connecting fixture 1 and the sliding seat 2. This structure is used to limit the forward and backward movement of the sliding seat 2, or to limit the forward and backward extreme positions of the sliding seat 2. The sliding limiting structure can be a combination of a stop block, a stop pin, a limiting hole, a limiting groove, etc.

[0076] Specifically, the bottom of the sliding seat 2 is provided with a first limiting post 21, and the top plate 13 of the fixture is provided with a first limiting hole 131 extending back and forth. The first limiting post 21 is fitted with the first limiting hole 131 with clearance.

[0077] To further improve the limiting effect, the side of the sliding seat 2 is provided with a second limiting post 22, and the side plate 12 of the fixture is provided with a second limiting hole 121 extending back and forth. The second limiting post 22 is fitted into the second limiting hole 121 with clearance.

[0078] An actuating elastic element 6 is connected between the connecting fixture 1 and the sliding seat 2 to drive the sliding seat 2 forward. The actuating elastic element 6 is a type of adaptive adjustment mechanism, and can be a spring, sheet metal, etc. When the actuating elastic element 6 is in the initial state, the sliding seat 2 moves forward to its limit position.

[0079] When the mobile device moves the entire vehicle body VIN code imprinting device toward the side of the vehicle body, the actuating elastic element 6 is in its initial state, the sliding seat 2 is positioned forward on the connecting fixture 1, and the imprinting paper adsorption plate 41 is also positioned forward. After the imprinting paper adsorption plate 41, carrying the imprinting paper 10, contacts the side of the vehicle body, it overcomes the elastic force of the actuating elastic element 6 and moves the sliding seat 2 backward a certain distance on the connecting fixture 1. At the same time, under the action of the actuating elastic element 6, the imprinting paper adsorption plate 41 can press against the vehicle body to facilitate subsequent imprinting operations.

[0080] In one embodiment, such as Figure 1 , Figure 3 and Figure 7As shown, a swing locking mechanism 7 is assembled between the sliding seat 2 and the swing seat 3. When the swing locking mechanism 7 is in the swing locked state, the swing seat 3 and the sliding seat 2 remain relatively fixed. When the swing locking mechanism 7 is in the swing unlocked state, the swing seat 3 can swing laterally relative to the sliding seat 2.

[0081] In this embodiment, a swing locking mechanism 7 is provided between the sliding seat 2 and the swing seat 3. The swing locking mechanism 7 can be a locking pin mechanism, a locking buckle mechanism, etc.

[0082] The swing locking mechanism 7 has a swing locked state and a swing unlocked state. When the swing locking mechanism 7 is in the swing locked state, it locks the swing seat 3 to the sliding seat 2, preventing the swing seat 3 from swinging. The swing locking mechanism 7 is needed to lock the swing seat 3 during loading of the vehicle body VIN code imprinting device and during the movement of the vehicle body VIN code imprinting device by the mobile equipment, preventing it from swinging, so as to facilitate loading and movement. After the swing locking mechanism 7 locks the swing seat 3, the swing seat 3 can move back and forth along with the sliding seat 2.

[0083] During the rubbing process, when the rubbing paper adsorption plate 41 contacts the vehicle body and pushes the sliding seat 2 back into place, the swing locking mechanism 7 is unlocked, and the swing seat 3 can swing.

[0084] In one embodiment, such as Figure 7 and Figure 9-10 As shown, the swing locking mechanism 7 includes a locking plate 71 with a T-shaped limiting groove 711, a locking member 72 connected to the sliding seat 2 and in clearance fit with the T-shaped limiting groove 711, and a locking plate drive module 73 connected to the swing seat 3 and used to drive the locking plate 71 to move longitudinally.

[0085] The T-shaped limiting groove 711 includes a longitudinal limiting groove 7111 and a transverse limiting groove 7112. The locking plate drive module 73 drives the locking plate 71 to move so that the locking member 72 can switch between the longitudinal limiting groove 7111 and the transverse limiting groove 7112.

[0086] In this embodiment, the swing locking mechanism 7 includes a locking plate 71, a locking member 72, and a locking plate drive module 73.

[0087] The locking plate 71 has a T-shaped limiting groove 711, which is located between the sliding seat 2 and the swing seat 3, and at the rear end. The T-shaped limiting groove 711 includes a longitudinal limiting groove 7111 and a transverse limiting groove 7112. The longitudinal limiting groove 7111 is preferably located on a longitudinal straight line passing through the center point O of the printing paper, and the transverse limiting groove 7112 is connected to the rear end of the longitudinal limiting groove 7111. Preferably, the T-shaped limiting grooves 711 are symmetrically arranged along the aforementioned longitudinal straight line. The front side walls of the transverse limiting groove 7112 can be set as inclined surfaces to provide clearance space for the swing of the locking member 72.

[0088] The locking element 72 is fixedly connected to the top of the sliding seat 2. The locking element 72 passes through the T-shaped limiting groove 711, the width of which is greater than the diameter of the locking element 72. The locking plate 71 can slide relative to the locking element 72, or the locking element 72 can slide within the T-shaped limiting groove 711. The locking element 72 can be a locking pin, locking post, etc. Preferably, a bearing is provided on the locking element 72 to reduce friction. Preferably, the locking element 72 is located on a longitudinal straight line passing through the center point O of the printing paper.

[0089] The locking plate drive module 73 is connected to the swing seat 3 via a bracket and is used to drive the locking plate 71 to move longitudinally. The locking plate drive module 73 is a telescopic drive mechanism, which can be a cylinder, hydraulic cylinder or similar mechanism. The rear end of the locking plate 71 is connected to the telescopic end of the locking plate drive module 73. When the locking plate drive module 73 drives the locking plate 71 to move back and forth, the locking member 72 can switch between the longitudinal limiting groove 7111 and the transverse limiting groove 7112.

[0090] When the locking plate drive module 73 is in its initial state, it pulls the locking plate 71 backward, causing the locking member 72 to be in the longitudinal limiting groove 7111. At this time, the swing locking mechanism 7 is in the swing locking state. When the locking member 72 is in the longitudinal limiting groove 7111, it restricts the swing of the swing seat 3 on the one hand, and provides guidance for the forward and backward movement of the sliding seat 2 on the other hand.

[0091] When the locking plate drive module 73 is in the extended state, the locking plate drive module 73 pushes the locking plate 71 forward, so that the locking member 72 is in the transverse limiting groove 7112. At this time, the swing locking mechanism 7 is in the swing unlocking state. When the locking member 72 is in the transverse limiting groove 7112, the swing seat 3 can swing, and the locking member 72 can swing with the swing seat 3 in the transverse limiting groove 7112.

[0092] Preferably, such as Figure 10 and Figure 12 As shown, the swing reset elastic element 8 is connected between the locking element 72 and the first connecting rod 511. A connecting rod 517 is provided at the bottom of the middle position of the first connecting rod 511. One end of the swing reset elastic element 8 is connected to the connecting rod 517, and the other end is connected to the locking element 72.

[0093] In one embodiment, such as Figure 1-3 He Ru Figure 6 As shown, the adsorption printing mechanism 4 includes a swing bracket 42 pivotally connected to the swing seat 3 and a bracket drive module 43 for driving the swing bracket 42 to swing up and down.

[0094] Two rubbing paper adsorption plates 41 are spaced apart on the swing bracket 42, and the two rubbing paper adsorption plates 41 are arranged in a fan shape relative to the pivot axis of the swing bracket 42.

[0095] The bracket drive module 43 drives the swing bracket 42 to swing so that the two printing paper adsorption plates 41 can alternately face forward.

[0096] In this embodiment, the adsorption printing mechanism 4 includes a swing bracket 42 and a bracket drive module 43. At least one end of the swing bracket 42 is pivotally connected to the swing base 3. The bracket drive module 43 is mounted on the swing base 3 and is used to drive the swing bracket 42 to swing up and down. The bracket drive module 43 can be a motor or a telescopic drive mechanism. The motor drives the swing bracket 42 to swing up and down by rotating the pivot shaft of the swing bracket 42. The telescopic end of the telescopic drive mechanism is hinged to the connecting arm 422 of the swing bracket 42 to drive the swing bracket 42 to swing up and down.

[0097] A pivot hole 421 is provided at the lower rear of the swing bracket 42 for engaging with the pivot shaft.

[0098] The swing bracket 42 is provided with two printing paper adsorption plates 41. The two printing paper adsorption plates 41 are arranged in a fan shape relative to the pivot axis of the swing bracket 42, and the central angle of the fan shape is preferably between 30° and 60°.

[0099] The bracket drive module 43 drives the swing bracket 42 to swing so that the two printing paper adsorption plates 41 can alternately face forward to meet the needs of printing two printing papers 10.

[0100] Specifically, during the printing process, the support drive module 43 drives the swing support 42 to its initial position. At this time, one printing paper adsorption plate 41 faces forward, and after the printing of one printing paper 10 is completed, the mobile device moves the vehicle body VIN code printing device backward. Then, the support drive module 43 drives the swing support 42 to swing at a preset angle, which is approximately the central angle of a sector, so that another printing paper adsorption plate 41 faces forward. After the second printing paper adsorption plate 41 adsorbs another printing paper 10 and completes the printing, two printing papers 10 are printed. Printing of two printing papers 10 can be completed with a single material pickup, improving printing efficiency.

[0101] In one embodiment, such as Figure 1-6 As shown, the adsorption printing mechanism 4 includes a printing motor 44 with a printing rotating head 441 and a multi-directional adjustment drive module 45 for driving the printing motor 44 to perform multi-directional position adjustment relative to the printing paper adsorption plate 41.

[0102] The printing paper adsorption plate 41 is provided with an adsorption plate opening 412 for the printing rotating head 441 to pass through, and the adsorption plate opening 412 extends laterally.

[0103] When the rubbing paper adsorption plate 41 adsorbs the rubbing paper 10, the rubbing paper 10 covers the opening 412 of the adsorption plate.

[0104] In this embodiment, the adsorption printing mechanism 4 includes a printing motor 44 and a multi-directional adjustment drive module 45. The front end of the printing motor 44 has a printing rotating head 441, which is used to press against the printing paper 10 and rotate for printing. The printing motor 44 is located above the swing seat 3 and is driven by the multi-directional adjustment drive module 45, which can perform multi-directional position adjustment, mainly involving lateral adjustment and longitudinal adjustment.

[0105] The multi-directional adjustment drive module 45 includes a lateral adjustment drive module 451 connected to the swing seat 3, a connecting seat 452 connected to the output end of the lateral adjustment drive module 451, a longitudinal adjustment drive module 453 connected to the connecting seat 452, and a connecting frame 454 connected to the output end of the longitudinal adjustment drive module 453. The printing motor 44 is connected to the connecting frame 454.

[0106] The lateral adjustment drive module 451 can drive the connecting seat 452, the longitudinal adjustment drive module 453, the connecting frame 454, and the printing motor 44 to move laterally. The longitudinal adjustment drive module 453 can drive the connecting frame 454 and the printing motor 44 to move longitudinally.

[0107] The printing paper adsorption plate 41 has a horizontally extending adsorption plate opening 412, which is rectangular. Adsorption ports 411 are located at both ends of the adsorption plate opening 412. The center point O of the printing paper is located in the middle of the adsorption plate opening 412. When the printing paper adsorption plate 41 adsorbs the printing paper 10, the printing paper 10 covers the front side of the adsorption plate opening 412. The adsorption plate opening 412 allows the printing rotating head 441 to pass through and press the printing paper 10 against the front side for printing.

[0108] Specifically, during the printing process, after the printing paper 10 is attached to the vehicle body, the longitudinal adjustment drive module 453 actuates first, causing the printing motor 44 to move forward with the printing rotating head 441 until it presses the printing paper 10 firmly. Then, the lateral adjustment drive module 451 actuates, causing the printing motor 44 to move laterally with the printing rotating head 441. It can move back and forth as needed, so that the printing rotating head 441 can rotate one side and move laterally along the suction plate opening 412 to complete the printing. After the printing is completed, the multi-directional adjustment drive module 45 drives the printing motor 44 to reset.

[0109] When each piece of printing paper adsorption plate 41 is in front, the printing rotating head 441 faces the adsorption plate opening 412 of the printing paper adsorption plate 41.

[0110] In one embodiment, such as Figure 5As shown, the front end face of the printing rotating head 441 is provided with multiple telescopic balls 442. When the printing rotating head 441 presses the printing paper 10 for printing, the telescopic balls 442 are forced to retract backward. Meanwhile, the balls inside the printing rotating head 441 press against the spring to counteract the telescopic balls 442, so that the telescopic balls 442 can better press the printing paper 10 and rotate and move laterally on the rear side of the printing paper 10, which helps to complete the printing quality.

[0111] In one embodiment, such as Figure 16 As shown, the vehicle body VIN code imprinting device is equipped with a protective cover 9, which is connected to the swing seat 3. The protective cover 9 covers the multi-directional adjustment drive module 45 and the bracket drive module 43, thus providing protection.

[0112] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0113] The above are merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
