[0041] See also Figure 1 The embodiment of the utility model provides a marking crimping structure 100, including a carrier 10, a driving assembly 20 and a pressing head assembly 30. The carrier 10 is provided with a plurality of first stations 11, and the plurality of first stations 11 are arranged along a first direction. The driving assembly 20 is provided at the first station 11 and is detachably connected to the carrier 10, and the pressing head assembly 30 is provided at the driving assembly 20, and the driving assembly 20 drives the pressing head assembly 30 to move in a direction close to or away from the carrier 10.

[0042] In an embodiment of the utility model, the driving component 20 can be detachably connected to the carrier 10 through the first station 11. The carrier 10 is provided with a plurality of first stations 11. By adjusting the driving component 20 to be located at different first stations 11, the position of the driving component 20 along the first direction can be adjusted, thereby adjusting the position of the pressure head assembly 30 provided on the driving component 20, thereby adapting to the crimping requirements of different marking positions and reducing the marking crimping cost.

[0043] Specifically, the carrier 10 is used to carry the product 200. The first station 11 is used for the drive assembly 20 to be detachably connected. There are many ways for the first station 11 to be detachably connected to the drive assembly 20. For example, in a certain embodiment, the first station 11 includes a plug-in protrusion arranged in the vertical direction, and the drive assembly 20 is provided with a plug-in groove that cooperates with the plug-in protrusion, and the drive assembly 20 maintains a connection relationship with the first station 11 under the action of gravity; in another embodiment, the first station 11 includes a card-connecting through hole, the card-connecting through hole is large at the top and small at the bottom, the drive assembly 20 is provided with a card-connecting protrusion, and a limiting groove is provided on the periphery of the card-connecting protrusion, the card-connecting protrusion can pass through the upper end of the card-connecting through hole, and the card-connecting protrusion can move downward so that the limiting groove cooperates with the card-connecting through hole, so as to realize the detachable connection between the drive assembly 20 and the first station 11. It can be understood that there are many ways for the first station 11 and the drive assembly 20 to be detachably connected, that is, there are many structures of the first station 11, and this application will not list them one by one.

[0044] The driving assembly 20 is used to drive the pressure head assembly 30 to move in a direction close to or away from the stage 10, so that when the product 200 needs to be marked, the pressure head assembly 30 can move in a direction close to the stage 10 to achieve crimping of the pressure head assembly 30 and the product 200. After the marking of the product 200 is completed, the pressure head assembly 30 can move in a direction away from the stage 10 to facilitate loading and unloading of the product 200. The driving assembly 20 may include a motor, a ball screw, a cylinder, and other driving devices, which are not specifically limited in this application.

[0045] The pressing head assembly 30 is used to press the product 200 to prevent the product 200 from shaking during the marking process, thereby ensuring the marking effect.

[0046] It is worth noting that the marking crimping structure 100 may include 1, 2, 3 or other number of carriers 10. The marking crimping structure 100 may include 1, 2, 3 or other number of drive assemblies 20. The marking crimping structure 100 may include 1, 2, 3 or other number of press head assemblies 30. It is understandable that the drive assembly 20 may correspond one-to-one with the carrier 10, or one drive assembly 20 may correspond to multiple carriers 10, and the present application does not make specific restrictions. The press head assembly 30 may correspond one-to-one with the carrier 10, or multiple press head assemblies 30 may correspond to one carrier 10, or multiple carriers 10 may correspond to one press head assembly 30. In a certain embodiment, the marking crimping structure 100 includes two carriers 10, two drive assemblies 20 and two press head assemblies 30, and the carriers 10, the drive assemblies 20 and the press head assemblies 30 correspond one-to-one. In this way, it is avoided that when the drive assembly 20 corresponds to multiple carriers 10, it is difficult to debug and align, and it is ensured that the pressure head assembly 30 driven by the drive assembly 20 can be crimped at the required position more accurately. In addition, since two pressure head assemblies 30 and two carriers 10 are provided, the efficiency of crimping and marking can be effectively accelerated. It is worth noting that the spacing between the two carriers 10 can be adjusted according to the spacing of the product 200 when it was unloaded in the previous process, so that the product 200 can be carried by the two carriers 10 as soon as it is unloaded. When the spacing between the two carriers 10 is not enough to install the drive assembly 20, the two drive assemblies 20 can be respectively located on the side of the two carriers 10 away from each other, so as to ensure that the two products 200 can be processed at the same time, while avoiding the drive assembly 20 affecting the loading and unloading efficiency of the product 200.

[0047] See also Figures 1 to 3 In the embodiment of the utility model, the first workstation 11 includes a plurality of first threaded holes 111, and the driving assembly 20 is provided with a driving mounting through hole 21, which is a waist-shaped hole arranged along the first direction. The driving mounting through hole 21 cooperates with the first threaded hole 111 to allow the driving assembly 20 to be bolted to the carrier 10.

[0048] In this way, the driving component 20 can be bolted to the first workstation 11 to achieve a detachable connection between the driving component 20 and the carrier 10. In addition, the relative position relationship between the driving component 20 and the carrier 10 can be adjusted through the waist-shaped hole, and the relative position relationship between the driving component 20 and the carrier 10 can be further adjusted to meet more marking and crimping requirements.

[0049] It can be understood that the first workstation 11 can include 1, 2, 3, 4 or other numbers of first threaded holes 111. The number of first threaded holes 111 included in the first workstation 11 can be adjusted according to factors such as the size of the drive assembly 20 and the weight of the drive assembly 20, and this application does not impose any specific restrictions.

[0050] It can be understood that the drive assembly 20 can be provided with 1, 2, 3, 4 or other number of drive mounting through holes 21, and the present application does not impose any specific limitation thereto.

[0051] See also Figures 1 to 3 In the embodiment of the utility model, the pressing head assembly 30 includes a crimping member 31 and a mounting member 33. The mounting member 33 is arranged on the driving assembly 20. The mounting member 33 is provided with a plurality of second stations 331. The plurality of second stations 331 are arranged along a second direction, and the second direction is perpendicular to the first direction. The crimping member 31 is detachably connected to the second station 331.

[0052] In this way, the crimping member 31 can be detachably connected to different second workstations 331 to achieve adjustment of the position of the crimping member 31 in the second direction, thereby adapting to different marking crimping requirements and reducing the crimping cost.

[0053] Specifically, there are many ways to detachably connect the crimping component 31 to the second station 331. The crimping component 31 can be detachably connected to the second station 331 by plugging, snapping, etc., and the crimping component 31 can also be bolted to the second station 331. This application does not make specific restrictions.

[0054] For further information, see Figures 1 to 3 The second station 331 includes a plurality of second threaded holes 3311, and the crimping piece 31 is provided with a crimping mounting through hole 311, which is a waist-shaped hole arranged along the second direction. The crimping mounting through hole 311 cooperates with the second threaded hole 3311 to allow the crimping piece 31 to be bolted to the mounting piece 33.

[0055] In this way, the crimping part 31 can be bolted to the second workstation 331 to achieve a detachable connection between the crimping part 31 and the mounting part 33. In addition, the relative position relationship between the crimping part 31 and the mounting part 33 can be adjusted through the waist-shaped hole, and the relative position relationship between the crimping part 31 and the carrier 10 can be further adjusted along the second direction to meet more marking crimping requirements.

[0056] It can be understood that the second workstation 331 may include 1, 2, 3, 4, etc. second threaded holes 3311, and the crimping part 31 may include 1, 2, 3, 4, etc. crimping mounting through holes 311, and the present application does not impose specific limitations.

[0057] For further information, see Figures 1 to 3 The crimping component 31 includes a crimping head 313 and a connecting member 315 , one end of the connecting member 315 is detachably connected to the crimping head 313 , the other end of the connecting member 315 is detachably connected to the mounting member 33 , and a crimping mounting through hole 311 is provided on the connecting member 315 .

[0058] In this way, since one end of the connecting piece 315 is detachably connected to the crimping head 313, and the other end of the connecting piece 315 is detachably connected to the mounting piece 33, when the crimping head 313 cannot be adjusted to the desired position through the second workstation 331 and the crimping mounting through hole 311, the connecting piece 315 can be conveniently removed and replaced to facilitate adjustment of the position of the crimping head 313 relative to the carrier 10 in the second direction, thereby adapting to the crimping requirements at different positions.

[0059] It can be understood that there are many ways to detachably connect the connector 315 and the crimping connector 313. The connector 315 can be detachably connected to the crimping connector 313 by means of threaded connection, bolted connection, or snap connection. There are many ways to detachably connect the connector 315 and the mounting member 33. The connector 315 and the mounting member 33 can be detachably connected by means of threaded connection, bolted connection, or snap connection, and this application does not impose any specific restrictions.

[0060] See also Figure 1 , Figure 4 and Figure 5 In the embodiment of the utility model, the pressure head assembly 30 includes a mounting seat 35, a crimping block 37, a guide member 38 and an elastic member 39. The mounting seat 35 is connected to the crimping block 37 through the guide member 38. The crimping block 37 can move closer to or away from the mounting seat 35 along the guide member 38. The two ends of the elastic member 39 are respectively abutted against the crimping block 37 and the mounting seat 35.

[0061] In this way, during the crimping process of the product 200, the elastic member 39 can provide elastic force for the crimping block 37 to ensure that the crimping block 37 can press the product 200. At the same time, since the elastic member 39 can be elastically deformed, the crimping block 37 can be prevented from crushing the product 200.

[0062] It can be understood that the crimping block 37 can move relative to the mounting seat 35 in a direction close to or away from the mounting seat 35 through the guide member 38, and the elastic member 39 provides elastic force for the crimping block 37 to press the crimping block 37 onto the product 200. When the pressure of the crimping block on the product 200 is too great, the elastic member 39 generates elastic force, so that the crimping block can move in a direction close to the mounting seat 35, thereby preventing the crimping block from crushing the product 200.

[0063] It is understandable that the elastic member 39 may include a spring, rubber, silicone or other elastic structure, and the present application does not impose any specific limitation thereto.

[0064] It is worth noting that the guide member 38 may include guide structures such as bearings and guide rails, and this application does not impose any specific restrictions.

[0065] For further information, see Figure 4 The pressure head assembly 30 includes two guide members 38, and the two guide members 38 are arranged in parallel and at intervals.

[0066] In this way, the two guide members 38 jointly limit the crimping block 37, further ensuring that the crimping block 37 moves in a straight line direction, and reducing the probability of shaking and deviation of the crimping block 37 during movement.

[0067] It can be understood that the structures of the two guide members 38 can be the same or different.

[0068] In the present utility model embodiment, please refer to Figure 4 and Figure 5 The guide member 38 includes a guide screw 381 and a linear bearing 383. The linear bearing 383 is disposed on the mounting seat 35. The guide screw 381 passes through the mounting seat 35 and is threadedly connected to the crimping block 37. The elastic member 39 is sleeved on the linear bearing 383.

[0069] and / or,

[0070] The guide member 38 includes a guide pin 385 and a bushing 387 . The guide pin 385 is disposed on the mounting seat 35 , and the bushing 387 is disposed on the crimping block 37 . The mounting seat 35 cooperates with the bushing 387 .

[0071] In this way, the cooperation between the guide screw 381 and the linear bearing 383 and / or the cooperation between the guide pin 385 and the bushing 387 can achieve the guiding effect of the movement of the crimping block 37.

[0072] It is understandable that the guide member 38 may include a guide screw 381 and a linear bearing 383, or may include a guide pin 385 and a bushing 387, or may include a guide screw 381, a linear bearing 383, a guide pin 385 and a bushing 387. The present application does not impose any specific restrictions.

[0073] It can be understood that the elastic member 39 can be sleeved on the guide pin 385.

[0074] See also Figures 4 to 7 In the embodiment of the utility model, the crimping block 37 includes two crimping protrusions 371, and the two crimping protrusions 371 are arranged at an interval.

[0075] In this way, the crimping protrusion 371 can crimp the product 200 to be marked to prevent the product 200 from shaking.

[0076] Understandable, see Figure 6 and Figure 7During the marking process of the product 200 whose area to be marked is a rectangle, the two crimping protrusions 371 can expose the two short sides of the rectangle of the product 200. Together with the exposed part of the long side of the rectangle, the visual sensor can locate the marking position through the two exposed short sides and part of the two long sides. In the related art, there are too many crimping positions, which block the two short sides, so that the visual sensor can only locate the marking position through the crimping block and the exposed long sides. When the crimping block shakes, the positioning of the visual sensor will be inaccurate. In contrast, in the present application, the visual sensor directly locates and marks through the area to be marked, which can avoid the influence of the shaking of the crimping block 37 on the marking positioning and achieve a better marking effect.

[0077] See also Figure 1 In the embodiment of the utility model, the carrier 10 includes a carrier 13 and two oppositely arranged supporting side plates 15. The two supporting side plates 15 are arranged in parallel along a first direction. The two supporting side plates 15 are respectively arranged on both sides of the carrier 13 to support the carrier 13. A plurality of first workstations 11 are arranged on the supporting side plates 15.

[0078] In this way, the driving assembly 20 can be arranged on the supporting side plate 15 so that there can be a certain height difference between the driving assembly 20 and the carrier 13, which facilitates the pressing head assembly 30 arranged on the driving assembly 20 to crimp the product 200 on the carrier 13, and avoids the problem that the height difference between the pressing head assembly 30 and the carrier 13 is too large, resulting in inaccurate crimping position of the pressing head assembly 30, shaking during movement, and other problems.

[0079] It is worth noting that the bearing member 13 may include a bottom plate and a limit plate, and two supporting side plates 15 are arranged on the bottom plate. The limit plate is used to carry the limit product 200, and the limit plate is detachably connected to the bottom plate. In this way, the limit plate can be conveniently replaced according to the different products 200 to achieve the limit of different products 200. Specifically, there are many ways to detachably connect the limit plate and the bottom plate, which can be the bottom plate and the limit plate. The limit plate can be connected by clamping, bolting, plugging, etc., and this application does not make specific restrictions. It is worth noting that the bottom plate can also be provided with a limit pin, and the limit plate is provided with a groove that cooperates with the limit pin. The limit pin and the groove cooperate to achieve the alignment of the limit plate and the bottom plate, which is convenient for the subsequent connection of the limit plate and the bottom plate.

[0080] See also Figure 1 and Figure 2 In the embodiment of the utility model, the driving assembly 20 includes a lifting driving member 23 and a rotating driving member 25. The lifting driving member 23 is used to drive the pressure head assembly 30 to move in a direction close to or away from the carrier 10, and the rotating driving member 25 is used to drive the pressure head assembly 30 to rotate.

[0081] In this way, not only can the ram assembly 30 be driven to move in a direction approaching or away from the carrier 10 to switch between the states of crimping the product 200 and releasing the crimping of the product 200, but the ram assembly 30 can also be driven to rotate to facilitate changing the position of the ram assembly 30 and facilitate loading and unloading of the product 200.

[0082] It can be understood that the lifting drive member 23 may include a linear motor, a cylinder or other drive device, and the rotating drive member 25 may include a motor, a rotating cylinder or other drive device, and the present application does not impose any specific restrictions.

[0083] An embodiment of the utility model also provides a marking device, which includes a marking crimping structure 100. The specific structure of the marking crimping structure 100 refers to the above embodiment. Since the marking device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0084] In the marking device in the embodiment of the utility model, the driving component 20 can be detachably connected to the carrier 10 through the first station 11. The carrier 10 is provided with multiple first stations 11. By adjusting the driving component 20 to be located at different first stations 11, the position of the driving component 20 along the first direction can be adjusted, thereby adjusting the position of the pressure head assembly 30 provided on the driving component 20, thereby adapting to the crimping requirements of different marking positions and reducing the marking crimping cost.
