Description

Technical Field

[0001] The present application relates to the technical field of marking equipment, and in particular to a marking device. Background Art

[0002] In the field of automotive electronics assembly, many products (such as high-voltage relays) need to be surface-marked before assembly. That is, the production date, manufacturer, national standard number, size specifications and other information need to be marked on the outer surface of the product through laser or inkjet printing to facilitate product traceability.

[0003] When marking, it is sometimes necessary to mark different surfaces of a single product, or sometimes to mark multiple products in batches. When marking different surfaces of a single product, the traditional method is for a person or a robot to flip the product over, then grab the marking head and print marks on different surfaces of the product. When marking multiple products separately, a person or a robot picks up each product one by one for marking. In these marking methods, manual operation is inefficient, prone to fatigue and errors, and has high labor costs. Robot operation requires space for installation, occupies a large area, and is also expensive to install, increasing the production cost of the equipment. Utility Model Content

[0031] The present application provides a marking device that can automatically mark different sides of a single product, or can automatically mark one side surface of different products, thereby solving the problem in the prior art of relying on manual flipping of products or manual picking up each product one by one for marking, which easily affects marking efficiency.

[0032] The following describes the structure of the marking device in this application using a high-voltage relay for a new energy vehicle as an example. It is understood that in other embodiments, the marking device in this application is not limited to marking the surface of a high-voltage relay, but can also mark the surface of any product, without limitation.

[0033] See Figure 1 , Figure 1A schematic diagram of a marking device 10 provided in an embodiment of the present application is shown. The marking device 10 provided in an embodiment of the present application includes a carrying mechanism 100 and a marking mechanism 200. The carrying mechanism 100 is used to carry a product 60 to be marked. The marking mechanism 200 is arranged on one side of the carrying mechanism 100 along a first horizontal direction (i.e., the X direction shown in the figure). It is used to print a mark on the side of the product 60, that is, to print information such as the production date, manufacturer, national standard number, size specifications, etc. on the side of the product 60 to facilitate people to trace the product 60.

[0034] Specifically, in one embodiment, Figure 2 As shown, the carrying mechanism 100 includes a carrying component 110, a rotating drive member 120 and a carrying platform 130, wherein the rotating drive member 120 is arranged on the carrying component 110, and the carrying platform 130 is connected to the rotating drive member 120. Under the drive of the rotating drive member 120, the carrying platform 130 can carry the product 60 and rotate around a central axis extending in a vertical direction (Z direction shown in the figure), so that when the carrying platform 130 carries only one product 60, different sides of the product 60 can be printed and marked by the printing mechanism, or when the carrying platform 130 carries a plurality of products 60 arranged along the circumference of the carrying platform 130, the side surface of each product 60 facing away from the central axis can be printed and marked by the marking mechanism 200.

[0035] Preferably, if Figure 3 As shown, a carrier 300 is provided on the supporting platform 130, and the carrier 300 is provided with a limiting groove 301 for accommodating the product 60, so that the product 60 will not be displaced relative to the carrier 300 when placed on the carrier 300, thereby preventing the product 60 from falling from the carrier 300. In the embodiment shown in the figure, the carrier 300 is provided with four limiting grooves 301, and the four limiting grooves 301 are distributed at intervals along the circumference of the carrier 300, so that the carrier 300 can carry four products 60. When the supporting platform 130 rotates 180° around the central axis extending in the vertical direction, one of the surfaces of all products 60 on the carrier 300 can face the marking mechanism 200 and can be printed and marked by the marking mechanism 200. Of course, it is understandable that the number of limit slots 301 opened on the carrier 300 is not limited, and can be one or more than two. When the number of limit slots 301 is multiple, the multiple limit slots 301 are distributed at intervals along the circumference of the carrier 300, so that when the supporting platform 130 drives the carrier 300 to rotate together, one of the surfaces of all products 60 can face the marking mechanism 200 and can be printed and marked by the marking mechanism 200.

[0036] Please continue reading Figure 2In a preferred embodiment, a positioning pin 131 is provided on the carrier platform 130, and a positioning hole (not shown in the figure) is opened on the bottom wall of the carrier 300. The positioning pin 131 is used to be inserted into the positioning hole to fix the carrier 300 on the carrier platform 130, thereby ensuring that there is no relative movement between the carrier 300 and the carrier platform 130, and further ensuring that the carrier 300 does not fall from the carrier platform 130.

[0037] More preferably, in order to realize automatic loading and circulation of product 60, as Figure 1 As shown, the marking device 10 provided by the present application further includes a conveyor line 400, which extends along a second horizontal direction (the Y direction shown in the figure) perpendicular to the first horizontal direction, and the carrier 300 is slidably arranged on the conveyor line 400. In this way, the conveyor line 400 can transport the carrier 300 carrying the product 60 from the upstream workstation to one side of the marking mechanism 200, so that the marking mechanism 200 can conveniently mark the product 60. After the marking is completed, the conveyor line 400 can transport the carrier 300 carrying the marked product 60 to the downstream workstation, so that the products 60 can be transported and circulated in a cyclical manner, thereby improving the degree of automation of the marking device 10.

[0038] Furthermore, in some embodiments, the marking mechanism 200 includes a marking machine 210, such as Figure 4 As shown, the marking machine 210 has a marking head (not shown) on the side facing the carrier mechanism 100. The marking head can print a mark on the product 60 by emitting a laser or spraying a code. Therefore, when the conveyor line 400 delivers the carrier 300 carrying the product 60 to a position (i.e., when it is delivered to the side of the marking mechanism 200 along the first horizontal direction), in order to stop the carrier 300 from being further conveyed by the conveyor line 400 and to enable the side of the product 60 on the carrier 300 to face the marking head so that it can be printed with a mark, in the embodiment provided in this application, the carrier assembly 110 can lift the carrier 300 to a certain height, thereby achieving the purpose of achieving the purpose of separating the carrier 300 from the conveyor line 400 and facing the marking head.

[0039] For details, please refer to Figure 2 and Figure 3The carrying assembly 110 includes a fixed seat 111, a first driving member (not shown in the figure) and a lifting plate 112. The first driving member is installed on the fixed seat 111, and the lifting plate 112 is movably arranged above the fixed seat 111 and connected to the first driving member. The rotating driving member 120 is arranged on the lifting plate 112, so that the first driving member can drive the lifting plate 112, the rotating driving member 120 and the carrying platform 130 to rise and fall relative to the fixed seat 111. Therefore, when the lifting plate 112 rises, the carrier 300 can rise together and separate from the conveyor line 400, and then can stop on one side of the marking mechanism 200 along the first horizontal direction, and can face the marking head; when the lifting plate 112 descends, the carrier 300 can descend together and be placed on the conveyor line 400, and then can be transported by the conveyor line 400.

[0040] Furthermore, in order to ensure that the first driving member does not deviate when lifting the lifting plate 112, the bearing assembly 110 further includes a second guide assembly 113, and the second guide assembly 113 includes two second guide shafts 1131 spaced apart. Each second guide shaft 1131 is connected to the lifting plate 112 and slidably penetrates the fixing seat 111. Figure 2 In the embodiment shown in , there are two sets of second guide assemblies 113, which are spaced apart along the first horizontal direction or along the second horizontal direction. Of course, the number of second guide assemblies 113 is not limited, and can be one or more sets. This ensures that when the lifting plate 112 is driven to move by the first driving member, the lifting plate 112 can only move in the vertical direction under the guidance of the second guide shaft 1131, thereby preventing deviation.

[0041] Please continue reading Figure 2 In an improved embodiment, the two second guide shafts 1131 of each second guide assembly 113 are further connected to each other by a second connecting plate 1132 at the end away from the lifting plate 112, and a second buffer 1133 is provided on the second connecting plate 1132. The second connecting plate 1132 and the second buffer 1133 are located below the fixed seat 111. The function of the second buffer 1133 is to provide a buffering effect. It is configured to abut against the fixed seat 111 when the lifting plate 112 rises, so as to slow down the lifting speed of the lifting plate 112 until the lifting plate 112 stops, so as to limit the vertical movement distance of the lifting plate 112 and avoid the lifting plate 112 from suddenly stopping when it is lifted to the maximum stroke, thereby preventing the product 60 carried on the carrier 300 from being subjected to a large inertial force and suddenly falling.

[0042] It is worth noting that in some working conditions, there is a high requirement for the cleanliness of the marking environment, that is, the product 60 needs to be marked in an environment with less dust. Therefore, in one embodiment, Figure 4 As shown, the marking mechanism 200 further includes a connecting shield 220 , which is disposed around an axis extending along a first horizontal direction and covers the marking head, so as to reduce the influence of dust in the environment on the marking head.

[0043] In order to further ensure the cleanliness of the marking environment, in an improved embodiment, Figure 1 and Figure 5 As shown, the marking device 10 also includes a cleaning mechanism 500, which includes a support frame 510, a second driving member 520 and a cleaning shield 530. The support frame 510 is a "door"-shaped structure, which includes a top plate 511 located above the carrier 130, and the cleaning shield 530 is open to one side of the marking mechanism 200. The cleaning shield 530 is movably located between the top plate 511 and the carrier 130. The second driving member 520 is installed on the top plate 511 and connected to the cleaning shield 530, so that the cleaning shield 530 can Driven by the second driving member 520, it descends relative to the support frame 510 to cover the carrier 130 and is connected to the connecting shield 220, so that the product 60 carried on the carrier 300 can be marked by the marking head in a closed space, thereby reducing the dust in the external environment from sticking to the product 60; or the cleaning shield 530 can rise relative to the support frame 510, so that the carrier 130 is exposed to the external environment, thereby avoiding the carrier 300, and facilitating the conveyor line 400 to transport the carrier 300 to the downstream workstation after the marking is completed.

[0044] Please continue reading Figure 5Similar to the carrying assembly 110, in order to guide the cleaning shield 530 when it moves in the vertical direction, the cleaning mechanism 500 also includes a first guide assembly 540. In the embodiment shown in the figure, the first guide assembly 540 has two groups, and the two groups of first guide assemblies 540 are arranged at intervals along the first horizontal direction or along the second horizontal direction. Similar to the second guide assembly 113, the number of first guide assemblies 540 can also be unlimited. Each first guide assembly 540 includes two first guide shafts 541, each of which is connected to the cleaning shield 530 and slides through the top of the support frame 510 (that is, through the top plate 511 of the support frame 510), and the two first guide shafts 541 are connected to each other at one end away from the cleaning shield 530 through a first connecting plate 542. Correspondingly, a stop block 544 is installed on the top plate 511 of the support frame 510, which is spaced apart from the first connecting plate 542 in the vertical direction, so that when the cleaning shield 530 moves downward a certain distance, the first connecting plate 542 can abut against the stop block 544, thereby limiting the moving distance of the cleaning shield 530 in the vertical direction. Furthermore, a first buffer 543 is also installed on the first connecting plate 542. The function of the first buffer 543 is the same as that of the second buffer 1133 described above, and it also serves as a buffer. It is configured to abut against the top of the support frame 510 when the cleaning shield 530 descends relative to the support frame 510, so as to slow down the descending speed of the cleaning shield 530 until the cleaning shield 530 stops, thereby avoiding the first connecting plate 542 from violently colliding with the stop block 544 and generating a large collision force.

[0045] In addition, although the cleaning shield 530 is covered on the carrier 300 so that the impact of external dust on the product 60 can be reduced during marking, a large amount of dust will also be generated during the marking process. Therefore, a dust exhaust element 560 of a blowing joint 550 is further provided on the cleaning shield 530. The dust exhaust element 560 is provided with a dust exhaust channel connected to the inner cavity of the cleaning shield 530. The blowing joint 550 is used to connect the air pipe. When the air pipe is connected to the blowing joint 550, it can blow air into the inner cavity of the cleaning shield 530. The dust exhaust channel is used to discharge the dust in the inner cavity of the cleaning shield 530 to the outside of the cleaning shield 530 when the air pipe blows air into the inner cavity of the cleaning shield 530, so that the cleanliness of the surface of the product 60 and the inner cavity of the cleaning shield 530 can be maintained to meet the cleanliness requirements during marking.

[0046] The following combined Figures 1 to 5 , the action flow of the marking device 10 provided in this application is introduced.

[0047] In the first step, the conveyor line 400 conveys the carrier 300 carrying the product 60 to the bottom of the cleaning module, and the first driving member drives the lifting plate 112 to move upward in the vertical direction, so that the positioning pin 131 of the lifting plate 112 is inserted into the positioning hole opened on the bottom wall of the carrier 300, and the carrier 300 is lifted to the set position.

[0048] In the second step, after the carrier 300 is lifted into place, the second driving member 520 drives the cleaning shield 530 to move downward in the vertical direction, so that the cleaning shield 530 covers the carrier 300 and is connected to the connecting shield 220 of the marking mechanism 200, so as to place the product 60 on the carrier 300 in a closed space.

[0049] In the third step, the marking mechanism 200 starts to mark one side surface of the product 60. During marking, the air pipe blows air into the inner cavity of the cleaning shield 530 through the blowing joint 550, and the dust generated during the marking process and the dust in the cleaning shield 530 are discharged through the dust exhaust channel of the dust exhaust element 560.

[0050] Step 4: After the marking is completed, the second driving member 520 drives the cleaning shield 530 to rise and return to its original position.

[0051] In the fifth step, the rotary drive member 120 drives the carrier 300 to rotate 180° around an axis extending in the vertical direction. In this way, when the carrier 300 carries only one product 60, the other opposite side surface of the product 60 can face the marking head of the marking mechanism 200. When the carrier 300 carries multiple products 60 (for example, four), after one side surface of two products 60 is printed and marked, one side surface of the remaining two products 60 can face the marking head.

[0052] Repeat steps 2 to 4. When the carrier 300 carries only one product 60, the marking can be completed on the other opposite side of the product 60. When the carrier 300 carries multiple products 60 (for example, four), after the marking is printed on one side of two products 60, the marking can be completed on the other side of the remaining two products 60.

[0053] In the sixth step, the first driving member drives the lifting plate 112 to descend, and places the carrier 300 back on the conveyor line 400 .

[0054] In the seventh step, the conveyor line 400 transports the carrier 300 carrying the marked product 60 to the downstream workstation, and the carrier 300 at the upstream workstation carries the new product 60 to the side of the marking mechanism 200, repeating the process from the first step to the seventh step.

[0055] It can be seen that the marking device provided in this application only needs to set up one marking station to achieve marking on different surfaces of a single product, or can achieve marking on one side surface of multiple products. The entire process is completed automatically without manual intervention or the installation of a robot. Therefore, it can reduce errors, improve marking speed and marking efficiency, and can reduce the overall equipment footprint of the marking device, effectively reducing hardware costs. When marking multiple products, multiple products can be marked at the same time, which can greatly meet the needs of product changes.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
