Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape marking equipment, in particular to an external marking device. Background Art

[0002] In the production process of carriers, in order to identify the information of electronic components on the carriers, the carriers need to be marked. The marking equipment for carriers is divided into built-in and external types.

[0003] Built-in marking equipment is usually closely integrated with the carrier processing machine and seamlessly integrated with the production line to achieve automated production processes. However, once the built-in marking equipment is installed, it is difficult to change its position or reconfigure it. When the marking equipment needs to be replaced or upgraded, it may require a long downtime and may involve the modification of the production line, making it less flexible and difficult to maintain. External marking equipment refers to independent marking devices that are not directly integrated into the production line. Compared with built-in marking equipment, this type of equipment has higher flexibility and can be placed in different positions of the production line according to actual needs to meet specific marking requirements. At the same time, external marking equipment is easier to maintain and upgrade, will not have much impact on the entire production line, and can also be used as general equipment on multiple production lines.

[0004] In the current existing technology, a single type of carrier is generally marked from top to bottom using a machine-type external marking device, which occupies a large space, has high production and processing costs, and is prone to safety accidents due to lack of protection during marking. When marking is required on different production lines, not only is loading and unloading and transportation difficult, it is also not suitable for a variety of types of carriers, and the accuracy and stability of marking are low, affecting the quality of marking. Utility Model Content

[0005] The purpose of the utility model is to provide an external marking device, aiming to solve the technical problems existing in the prior art of external marking equipment, such as high production and processing cost, low safety factor, difficult loading and unloading and transportation, unsuitability for various types of carriers, low marking accuracy and stability, affecting the marking quality, etc.

[0006] In order to solve the above technical problems, the utility model provides an external marking device, including: a mounting support, including a base, a marking plate arranged above the base, and a protective plate and two side plates located between the base and the marking plate, the two side plates are arranged opposite to each other, and the protective plate is provided with a feed port near the marking plate; a width adjustment component, movably arranged on the mounting support, including two width adjustment blocks symmetrically arranged on both sides of the feed port, and the two width adjustment blocks can move toward or away from each other to adjust the size of the feed port; a marking mechanism, arranged on the mounting support and located between the two side plates, including a guide drive component and a marking component, the guide drive component is used to drive the marking component to approach or move away from the marking plate.

[0007] The two oppositely arranged side panels can, on the one hand, divide the direction in which the product enters and exits the mounting support, making it less likely for the device to make mistakes during installation; on the other hand, they can isolate the opposite sides of the mounting support from the outside world, which can play a certain role in protecting the internal marking mechanism of the mounting support, and at the same time, to a certain extent, prevent external people and objects from reaching into the mounting support and affecting its operation, thereby reducing the occurrence of safety accidents; when there are already two opposite side panels on the mounting support, the protective plate is further arranged on one of the remaining two sides of the mounting support, further enhancing the effect of protecting the internal marking mechanism of the mounting support and preventing safety accidents; the setting of the feed port further enhances the effect of dividing the direction in which the product enters and exits the mounting support, improving the accuracy of the installation of the device, and in addition, the products to be processed can be restricted to a small area to pass through and be marked;

[0008] The two width adjustment blocks can adjust the distance between them, and then adjust the size of the feed opening to adapt to different types of products to be processed, so that they can accurately enter the mounting support and be marked, which is beneficial to improve the stability and accuracy of the products to be processed passing through the mounting support, and then improve the accuracy and quality of marking; the external manifestation of the device is a mounting support with a small volume and simple structure. After the product enters the inside of the mounting support from the outside of the mounting support, it can be marked from bottom to top, abandoning the large machine required for top-down marking used in the prior art, so that the overall structure is simplified, and then it can effectively reduce the floor space and production and processing costs, and reduce the difficulty of loading and unloading and carrying of the device.

[0009] Preferably, the guide drive assembly includes a driving member arranged on the base, a header mounting seat connected to the output end of the driving member, and a plurality of guide shafts spaced between the base and the marking plate, the header mounting seat is movably clamped on the plurality of guide shafts, and the driving member is used to drive the header mounting seat to slide along the plurality of guide shafts.

[0010] On the one hand, the guide shaft can improve the stability of the moving path of the driving member driving the head mounting seat, prevent the head mounting seat from being offset due to accidents, and cause the marking position to be offset, thereby affecting the marking quality. On the other hand, it can reduce the jitter between the base and the marking plate caused by the outside world, and improve the overall stability and rigidity of the mounting support; multiple guide shafts are arranged at intervals, which can further improve their effect and the stability of the mounting seat when moving; multiple guide shafts can also prevent the displacement path of the head mounting seat from being offset due to the failure of one or more guide shafts, so that the marking accuracy of the marking head on the processed product is reduced, which is beneficial to improving the marking quality. At the same time, it can disperse the load of the head mounting seat, reduce the wear of each guide shaft, and increase the service life of the guide shaft.

[0011] Preferably, the plurality of guide shafts are detachably connected to the base and the marking plate.

[0012] When one of the guide shafts is worn or fails, it can be replaced individually without disassembling the entire device, effectively reducing the loss of downtime and the cost of subsequent maintenance; similarly, when it is necessary to adjust the structure of the device or add additional functions, the detachable guide shaft can be quickly rearranged, which is conducive to improving the expandability of the device.

[0013] Preferably, a plurality of guide sleeves are provided on the header mounting seat, and the plurality of guide sleeves are movably sleeved on the plurality of guide shafts respectively.

[0014] The guide shaft sleeve can be used as a contact piece between the guide shaft and the header mounting seat. On the one hand, it can reduce the wear caused by direct contact between the two. The use of materials with a lower friction coefficient can make the header mounting seat slide more smoothly on the guide shaft, further reducing wear, increasing the service life of the guide shaft and the moving seat, and reducing the maintenance cost caused by replacement of the guide shaft and the moving seat due to wear. On the other hand, it can fine-tune the gap between the guide shaft and the moving seat, improve the assembly accuracy between the guide shaft and the header mounting seat, and further improve the stability of the header mounting seat moving along the guide shaft.

[0015] Preferably, the marking assembly includes a header mounting plate and a plurality of marking heads spaced apart on the header mounting plate, the plurality of marking heads are opposite to the marking plate, and the plurality of marking heads and the header mounting plate, and the header mounting plate and the header mounting seat are all detachably connected.

[0016] When the device needs to be replaced on a different production line, or when the marking head needs to be replaced for different marking requirements, the marking head installation plate can replace all the marking heads at one time, which greatly reduces the time required to replace all the marking heads, effectively reduces the difficulty of replacing the marking heads, and improves the replacement efficiency of the marking heads; Multiple marking heads themselves can improve the efficiency of marking. The detachable function can, on the one hand, increase the types of marking heads that can be adapted to different marking requirements, and improve the applicability and expandability of the device; on the other hand, when the marking head fails or is damaged, it can be replaced quickly and easily without causing much impact on the product processing production line, effectively improving the loading and unloading efficiency of the marking head and reducing the difficulty of later maintenance;

[0017] The base is also provided with a plurality of positioning holes arranged at intervals.

[0018] Multiple positioning holes arranged at intervals can quickly align and fix the base, simplifying the installation process, thereby effectively improving the installation efficiency of the device, reducing the error rate, and facilitating subsequent maintenance; the installation position of the device can be quickly adjusted as needed, which can improve the flexibility of the installation of the device, and then the device can be easily and quickly installed at the required predetermined position, and the marking component can be aligned with the carrier, improving the accuracy and quality of marking; it can also provide a more stable connection to ensure that the device can be more secure and reliable when installed at the predetermined position.

[0019] Preferably, the connection relationship between the base, the marking plate, the two side plates, and the protective plate is a detachable connection.

[0020] This detachable connection is equivalent to the entire mounting bracket being able to be disassembled into a base, a marking plate, two side panels, and a protective plate. When the device is not needed, it can be disassembled to reduce the floor space. When the device is needed, the weight of a single transport can be reduced, the difficulty of transport can be reduced, and it can be assembled at any time. In addition, when the structure of the device needs to be adjusted or additional functions need to be added, these detachable parts can be replaced at will, which can effectively improve the flexibility and expandability of the device.

[0021] Preferably, the width adjustment block is provided with an elongated hole, and the width adjustment block is connected to the side plate by bolts, one end of the bolt passes through the elongated hole and is connected to the side plate, and the other end of the bolt can abut the width adjustment block.

[0022] By loosening the bolts and sliding the width adjustment block along the marking plate and the protective plate, the relative position between the width adjustment block and the side plate is changed. The distance between the two width adjustment blocks can be changed in a short time to adapt to products to be processed with different widths. There is no need to prepare multiple special components for items of different widths, which effectively reduces space occupancy, reduces the production and processing costs of the device, and improves the flexibility and expandability of the device.

[0023] Preferably, opposite ends of the two width adjustment blocks are each provided with a penetrating stepped groove, the stepped groove is opposite to the marking plate and forms a limiting groove with the marking plate, and the two limiting grooves are opposite to each other.

[0024] When the product to be processed passes through the two width adjustment blocks and enters the interior of the mounting support, it is clamped by the opposite ends of the two width adjustment blocks. Although it is restricted from deviating toward the end directions of the two width adjustment blocks, it may still deviate toward the base or the marking plate. Therefore, the limit groove provides vertical support and restriction for the product to be processed, so that the product to be processed can only slide along the limit groove into the interior of the mounting support, which is beneficial to improve the stability and accuracy of the product to be processed through the mounting support, thereby improving the accuracy and effect of marking.

[0025] Preferably, an end of the stepped groove away from the marking plate is provided with an inclined opening opened outward.

[0026] When the product to be processed is first passed through the mounting support or the height of the product to be processed is unstable when entering the mounting support, the inclined opening can guide the product to be processed to enter the interior of the mounting support more smoothly, automatically correct its position when entering the interior of the mounting support, effectively reduce unnecessary wear of the product to be processed due to the sharp groove, improve the stability and accuracy of the product to be processed passing through the mounting support, and thus improve the accuracy and effect of marking.

[0027] Compared with the prior art, the beneficial effects of the utility model are:

[0028] Instead of using a machine stand or other space-consuming pedestal, a mounting bracket that takes up less space is used, which effectively reduces the size of the device, reduces the production and processing costs, and reduces the difficulty of loading, unloading, and transportation. Two side panels and a protective plate are used to isolate the marking mechanism inside the mounting bracket, which can protect the normal marking process while improving the safety factor during operation. The width adjustment component can adjust the size of the feed port so that various types of carriers can enter the mounting bracket smoothly and accurately to be marked by the marking mechanism, effectively improving the stability and accuracy of marking, thereby improving the marking quality.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] In this embodiment, please refer to Figure 1 and Figure 2As shown, the present invention provides an external marking device, which includes a mounting support 10, a width adjustment component movably arranged on the mounting support 10, and a marking mechanism 20 arranged in the mounting support 10. The mounting support 10 includes a base 11, a marking plate 13, and two side plates 14. The two side plates 14 are arranged opposite to each other and are located on both sides of the base 11. The protective plate 15 is connected to the two side plates 14 and is located on one of the remaining two sides of the base 11. A feed port 151 is provided on the protective plate 15 near the marking plate 13; the width adjustment component includes two width adjustment blocks 30, and the two width adjustment blocks 30 can abut the marking plate 13 and the protective plate 15. They can move toward or away from the marking plate 13 and the protective plate 15 to shrink or expand the size of the feed port 151; the marking mechanism 20 is located between the two side plates 14, and includes a guide drive component and a marking component. The guide drive component is used to drive the marking component to move along the direction of its guide so that the marking component is close to or away from the marking plate 13 to complete repeated marking of the carrier.

[0038] It can be understood that the base 11, the marking plate 13, the two side plates 14, and the protective plate 15 of the mounting support 10 should be a rectangular parallelepiped structure in an ideal simplified state, with the bottom and top being the base 11 and the marking plate 13, the two opposite side plates 14 and the protective plate 15 connecting the base 11 and the marking plate 13 near the edge, and surrounding the marking mechanism 20 arranged inside the mounting support 10, the carrier tape enters the interior of the mounting support 10 from the feed port 151 on the protective plate 15, and the other side opposite to the protective plate 15 is not provided with a baffle. It can be used as an outlet for the marked carrier to leave the mounting bracket 10, and the guide direction of the driving component driving the marking mechanism 20 should be perpendicular to the marking plate 13; in addition, when the marking component marks the carrier, the carrier will abut the marking plate 13. If there is a step structure between the feed port 151 and the marking plate 13, it may cause damage to the carrier. Therefore, the shape of the feed port 151 is not restricted as long as it does not cover the marking plate 13 and allows different types of products to be processed to enter the interior of the mounting bracket 10.

[0039] The movement of the two width adjustment blocks 30 is jointly constrained by the protective plate 15 and the marking plate 13. In order to make the two width adjustment blocks 30 more convenient to adjust and move, they should be set on the inner side of the protective plate 15, abutting the inner side of the marking plate 13 against the inner side of the mounting support 10, and a groove compatible with the width adjustment block 30 is reserved on the side plate 14, so that the marking plate 13, the protective plate 15 and the side plate 14 can jointly limit the movement direction of the width adjustment block 30, and the inner side and the outer side are relative to the inside and the outside of the mounting support 10; the two width adjustment blocks 30 are used to adjust the opening width at the feed port 151 to adapt to the needs of different products entering and exiting the mounting support 10 and being processed. It is not important where they are connected themselves, so they can be movably connected only to the protective plate 15, or they can be movably connected to the protective plate 15 and the side plate 14 at the same time, and they can even be set on the marking plate 13 extending out of the outside of the protective plate 15.

[0040] In addition, according to actual needs, the side panel 14 can be designed to have other structures such as grids, reinforcing ribs, curved surfaces, folded surfaces, etc., to meet its strength, protection, or reduce other functions such as space occupancy; a corresponding plate structure can also be set on the opposite side of the protective plate 15, but a discharge port needs to be reserved; two width adjustment blocks 30 can also be set on the outer side of the protective plate 15, abutting the inner side of the marking plate 13 against the inside of the mounting bracket 10, and its movement direction is only constrained by the marking plate 13 and the protective plate 15.

[0041] In addition, the opposing surfaces of the base 11 and the marking plate 13 are not limited to rectangles, and may be circular, trapezoidal, annular, etc., and can adapt to various space occupation requirements without affecting the marking of the marking mechanism 20; the driving member 21 may not require spring reset, and the cylinder 211 may switch the direction of the airflow to complete the reciprocating linear motion of the header mounting seat 22, and a linear motor or other mechanism may be used as the power source for the reciprocating linear motion of the header mounting seat 22; the header mounting seat 22 may be provided with guide holes or guide grooves that cooperate with multiple guide shafts 12, and the guide grooves are located on the peripheral side of the header mounting seat 22; multiple marking heads 23 may also be arranged in multiple rows at intervals, or their directions may be changed to rows or multiple rows.

[0042] In one embodiment, please refer to Figure 1 and Figure 3As shown, the guide drive assembly includes a driving member 21 arranged on the base 11, a header mounting seat 22 connected to the output end of the driving member 21, and a plurality of guide shafts 12 arranged between the base 11 and the marking plate 13 at intervals. The plurality of guide shafts 12 are connected to the base 11 and the marking plate 13. The plurality of guide shafts 12 pass through the header mounting seat 22 and make the header mounting seat 22 movably clamped on the plurality of guide shafts 12, and the header mounting seat 22 can slide along the plurality of guide shafts 12. The driving member 21 is specifically a cylinder 211 and a piston rod 212. The header mounting seat 22 is fixedly connected to one end of the piston rod 212. The cylinder 211 drives the header mounting seat 22 to move along the plurality of guide shafts 12 through the piston rod 212, so that the marking assembly also moves close to or away from the marking plate 13 along the plurality of guide shafts 12 together with the header mounting seat 22.

[0043] It can be understood that the multiple guide shafts 12 should be perpendicular to the base 11 and the marking plate 13 when the mounting support 10 is in an ideal simplified state, that is, the moving path of the header mounting seat 22 and the marking assembly is perpendicular to the marking plate 13. When the base 11 is accurately installed in the specified position, the marking assembly can be accurately aligned with the product to be processed and processed; the header mounting seat 22 and the multiple guide shafts 12 only need to satisfy a sliding matching relationship. Therefore, without affecting the driving member 21 driving the header mounting seat 22 and the marking of the marking assembly, the multiple guide shafts 12 can pass through any position of the header mounting seat 22; in addition, linear motors, hydraulics, etc. can also be used as the driving member 21.

[0044] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the multiple guide shafts 12 are detachably connected to the base 11 and the marking plate 13, specifically, they are threaded. It is understandable that corresponding countersunk through holes or threaded holes should be provided on the base 11, the marking plate 13, and the multiple guide shafts 12, and the multiple guide shafts 12 are fixed between the base 11 and the marking plate 13 by bolts 33 or other threaded structures.

[0045] In addition, the guide shaft 12 itself can also be provided with threads at both ends, and correspondingly, thread grooves or holes are provided on the base 11 and the marking plate 13 .

[0046] Specifically, please refer to Figure 1 and Figure 3As shown, a plurality of guide sleeves 221 are provided on the header mounting seat 22. These guide sleeves 221 are in a "T"-shaped structure and are respectively sleeved on a plurality of guide shafts 12. It can be understood that the number of guide sleeves 221 should be greater than or equal to the number of guide shafts 12. The guide sleeves 221 serve as contact members between the header mounting seat 22 and the guide shafts 12. There is no relative movement between the guide sleeves 221 and the header mounting seat 22. Therefore, the guide sleeves 221 and the header mounting seat 22 are fixedly connected.

[0047] In addition, the guide shaft sleeve 221 can also be an “I” type, or a structure with pipe threads, and can be detachably connected to the header mounting seat 22 .

[0048] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the marking assembly includes a header mounting plate 24 arranged on a header mounting seat 22 and a plurality of marking heads 23 installed at intervals on the header mounting plate 24. The plurality of marking heads 23 are all opposite to the marking plate 13. The header mounting plate 24 and the header mounting seat 22, as well as the plurality of marking heads 23 and the header mounting plate 24 are all detachably connected. Specifically, the header mounting seat 22 is a "concave" structure, and the header mounting plate 24 is a "convex" structure. The header mounting plate 24 is installed in the groove of the header mounting seat 22. The plurality of marking heads 23 are arranged at intervals at the protruding position of the header mounting plate 24. The two sides of the protrusion are connected to the header mounting seat 22 by bolts 33 to fix the header mounting plate 24.

[0049] It can be understood that the arrangement of the multiple marking heads 23 is the same as the arrangement of the products to be processed when they enter the mounting bracket; at this time, the marking heads 23 are only connected to the marking head mounting plate 24 and will not contact the marking head mounting seat 22.

[0050] In addition, the threaded matching connection between the marking head 23 and the marking head mounting plate 24 can be that the marking head 23 is provided with a threaded column and the marking head mounting plate 24 is provided with a threaded slot, or vice versa; the detachable connection between the marking head mounting plate 24 and the marking head mounting seat 22 can be that the marking head mounting plate 24 and the marking head mounting seat 22 are clamped together; the concave and convex structure of the marking head mounting seat 22 and the marking head mounting plate 24 is to reduce the relative movement between them and accelerate positioning and loading and unloading, and both can also be other structures such as flat plate structures or further tooth surface structures.

[0051] In one embodiment, please refer to Figure 1 and Figure 2 As shown, the base 11 is further provided with a plurality of positioning holes 111 .

[0052] It can be understood that these positioning holes 111 are used to install the base 11 at a designated position where the device is required. Accordingly, the designated position should be provided with holes or grooves corresponding to and matching the plurality of positioning holes 111 .

[0053] In addition, the shape of the positioning hole 111 can be a strip, a circle, a square, etc., so as to realize the positioning of the base 11 and not cause the bottom plate to deviate from the specified position after installation.

[0054] Specifically, the connection relationship between the base 11, the marking plate 13, the two side plates 14, and the protective plate 15 are all detachable connections.

[0055] It can be understood that, by cooperating with the detachable connection between the multiple guide shafts 12 and the base 11 and the marking plate 13, the various plates of the mounting support 10 can be disassembled, and this feature can be utilized in transportation, loading and unloading, and modular design.

[0056] In addition, the width adjustment block 30 may also be detachably connected therebetween.

[0057] In this embodiment, please refer to Figure 2 and Figure 3 The width adjustment block 30 is also provided with a long strip hole, and the width adjustment block 30 is connected to the side plate 14 by bolts.

[0058] It can be understood that the width adjustment block 30 is also a rectangular parallelepiped structure and can be located on the inner side or the outer side of the protection plate 15 , and the inner and outer sides are related to the inner and outer sides of the mounting bracket 10 .

[0059] When the elongated hole faces the protective plate 15 and the width adjustment block 30 is located outside the protective plate 15, one end of the bolt 33 passes through the elongated hole and the protective plate 15 and is connected with the side plate 14, and the other end abuts against the width adjustment block 30 to fix the width adjustment block 30. When the width adjustment block 30 is located inside the protective plate 15, a through hole is provided on the protective plate 15, and a groove for accommodating the width adjustment block 30 is provided on the side plate 14. One end of the bolt 33 passes through the through hole and the elongated hole and is connected with the side plate 14, and the other end abuts against the width adjustment block 30 to fix the width adjustment block 30.

[0060] When the elongated hole faces the marking plate 13 and the width adjustment block 30 is located outside the protective plate 15, one end of the bolt 33 passes through the elongated hole and the marking plate 13, and the other end abuts the width adjustment block 30. When the width adjustment block 30 is located inside the protective plate 15, a through hole is provided on the marking plate 13, and a groove for accommodating the width adjustment block 30 is provided on the side plate 14. One end of the bolt 33 passes through the through hole and the elongated hole and is connected with the side plate 14, and the other end abuts the width adjustment block 30 to fix the width adjustment block 30.

[0061] When the distance between the two width adjustment blocks 30 needs to be adjusted, the bolts 33 can be unscrewed a certain distance to push the two width adjustment blocks 30 to move along the direction constrained by the protection plate 15 and the marking plate 13 to adjust the size of the feed port 151.

[0062] In addition, a locking bolt 33 may be provided on the marking plate 13 or the protection plate 15 , and the screwing depth may be adjusted to lock the two width adjustment blocks 30 .

[0063] Specifically, opposite ends of the two width adjustment blocks 30 are each provided with a penetrating stepped groove, the stepped groove is opposite to the marking plate 13 and forms a limiting groove 31 with the marking plate 13 , and the two limiting grooves 31 are opposite to each other.

[0064] It can be understood that the two width adjustment blocks 30 are both rectangular structures, and a rectangular block is cut out of the edges of the opposite surfaces that abut the marking plate 13. The cut-off part has a stepped structure, which is a step groove. The penetration direction of the step groove is the direction in which the product to be processed enters and exits the mounting support 10, and together with the marking plate 13, a limiting groove 31 is formed as a channel for the product to be processed to enter the interior of the mounting support 10.

[0065] More specifically, the end of the stepped groove away from the marking plate 13 is provided with an inclined opening 32 opened outward. It can be understood that the inclined opening 32 is used to guide the product to be processed to enter the interior of the mounting support 10 more smoothly, automatically correct the position of the product entering the interior of the mounting support 10, so as to reduce unnecessary wear of the product to be processed due to the sharp notch.

[0066] In addition, an inclined opening 32 opened outward may also be provided at the outer ends of the feed port 151 and the marking plate 13 .

[0067] The specific application process of the utility model is as follows:
