Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0025] According to embodiments of the present invention, in one aspect, an alignment mechanism is provided, such as... Figure 1 and Figure 2As shown, the alignment mechanism includes a frame 1, a first clamp 2 mounted on the frame 1, a lifting assembly 5, a second clamp 3, and an adjusting assembly 4. The second clamp 3 is detachably connected to the first clamp 2, and the adjusting assembly 4 is mounted on the second clamp 3. It should be noted that... Figure 1 The illustration only shows the state when the second clamp 3 is installed on the first clamp 2, and the adjustment component 4 is not shown. Figure 2 The diagram shows a schematic of the structure of the second clamp 3 and the adjustment component 4.

[0026] Specifically, the lifting assembly 5 has a lifting seat 51, which is vertically oriented and located below the first clamp 2. The lifting seat 51 is used to place the pad printing plate 8 and move the pad printing plate 8 up and down. The adjusting assembly 4 is positionally adjustable to the second clamp 3. In the height direction Z, the second clamp 3 and the adjusting assembly 4 are located between the first clamp 2 and the lifting seat 51. The adjusting assembly 4 is used to install the adhesive head 7 and adjust the installation position of the adhesive head 7 on the second clamp 3 according to the pad printing plate 8.

[0027] In this embodiment, the lifting component 5 simulates the position of the pad printing steel plate 8, and the adjusting component 4 adjusts the position of the pad printing head 7 in advance according to the position of the pad printing pattern on the pad printing steel plate 8. During the changeover, only the second clamp 3 is removed from the first clamp 2 and installed on the pad printing mechanism, realizing "offline debugging + inline instant cutting", which greatly shortens the changeover time, thereby shortening the downtime of the pad printing equipment and improving the production efficiency of the product.

[0028] Furthermore, in some embodiments, the alignment mechanism further includes a first pneumatic actuator, the first clamp 2 includes a first clamping part, and the second clamp 3 includes a second clamping part. The first pneumatic actuator is connected to the first clamping part and / or the second clamping part, and is used to drive the first clamping part and the second clamping part to clamp and release each other. In this embodiment, by using the first pneumatic actuator to drive the first clamping part and the second clamping part to clamp and release each other, the pneumatic clamping or releasing of the first clamp 2 and the second clamp 3 is achieved, resulting in high assembly and disassembly efficiency, further shortening changeover time, and improving product production efficiency.

[0029] Specifically, the first pneumatic actuator may include a pneumatic element, an air source, and a control element. The air source provides compressed gas to the pneumatic element, and the control element is electrically connected to the pneumatic element. The control element controls the movement of the pneumatic element to achieve mutual clamping and releasing between the first clamping part and the second clamping part. Exemplarily, the pneumatic element may be a cylinder, a cylinder and a slider, or a cylinder and a ball bearing structure, etc. Exemplarily, the control element may be a pneumatic solenoid valve, a pneumatic directional valve, etc. Exemplarily, the first pneumatic actuator may be connected to the first clamping part, which may be a gripper, and the second clamping part may be a groove matching the gripper. Exemplarily, the first pneumatic actuator may be connected to the second clamping part, which may be a gripper, and the first clamping part may be a groove matching the gripper. Exemplarily, the first clamping part may also have a portion of its structure connected to the first clamping part and a portion of its structure connected to the second clamping part.

[0030] It should be noted that this utility model does not specifically limit the structure of the first clamp 2, the second clamp 3, and the first pneumatic actuator, as long as the pneumatic clamping function of the first clamp 2 and the second clamp 3 can be realized.

[0031] Of course, in some cases, the first clamp 2 and the second clamp 3 can also be connected by other structures such as fasteners or manual clamping structures, as long as the detachable function of both can be achieved.

[0032] Furthermore, such as Figure 1 As shown, in some embodiments, the lifting assembly 5 includes a lifting drive 52. The lifting drive 52 is mounted on the frame 1 and is connected to the lifting seat 51 via a transmission connection. The lifting drive 52 is used to drive the lifting seat 51 to rise and fall. Using the lifting drive 52 to drive the lifting seat 51 to rise and fall, the lifting is smooth, and the lifting position can be adjusted at any time.

[0033] Specifically, the lifting drive component 52 may include a threaded rod 521 and a rotating component 522. The rotating component 522 is connected to one end of the threaded rod 521 and is used to drive the threaded rod 521 to rotate. The lifting seat 51 is provided with a transmission connection part 514, which has an internal threaded hole that extends along the height direction. The threaded rod 521 passes through and is threaded into the internal threaded hole.

[0034] For example, the rotating member 522 can be a rotating handle, which is rotated by external force to drive the threaded rod 521 to rotate. In this case, the lifting drive member 52 also includes a locking structure 523, which may include a locking block disposed on the rotating member 522 and a locking member passing through the locking block. When the locking member is tightened, the locking block restricts the rotation of the rotating member 522; when the locking member is loosened, the locking block allows the rotating member 522 to rotate.

[0035] For example, the rotating component 522 can be a rotary motor, such as a stepper motor, which can automatically drive the threaded rod 521 to rotate or stop rotating, resulting in higher lifting efficiency and better stability.

[0036] In some embodiments, the lifting assembly 5 includes a guide 53, which is disposed on the frame 1 and slidably connected to the lifting seat 51 along the height direction Z. The guide 53 guides the lifting of the lifting seat 51, preventing lifting jamming due to uneven load on the lifting seat 51 and improving the reliability of equipment operation.

[0037] For example, the guide member 53 may include at least one guide rail extending along the height direction Z, and the lifting seat 51 is slidably connected to the guide rail by its own structure or a slider. For example, the guide member 53 may include two guide rails, with the two guide rails and the threaded rod 521 located on the same side of the lifting seat 51, and the two guide rails located on opposite sides of the threaded rod 521.

[0038] Furthermore, the frame 1 includes a top plate 11 and a bottom plate 12 opposite each other in the height direction Z, and a side plate 13 connecting the top plate 11 and the bottom plate 12. Figure 1 As shown, the side plate 13 connects the top plate 11 and the bottom plate 12, and is located on one side of the top plate 11 and the bottom plate 12 along the second direction Y. The other side of the top plate 11 and the bottom plate 12 along the second direction Y, as well as both sides of the top plate 11 and the bottom plate 12 along the first direction X, are open to facilitate the adjustment of the position of the rubber head 7 by the debugging personnel. The first direction X and the second direction Y both intersect the height direction Z. In some cases, the first direction X is the length direction of the alignment mechanism, the second direction Y is the width direction of the alignment mechanism, and the first direction X and the second direction Y are perpendicular to the height direction Z.

[0039] Furthermore, the aforementioned lifting drive component 52 can be connected to the top plate 11; the aforementioned guide component 53 can be connected to the side plate 13, and the threaded rod 521 of the guide component 53 and the lifting drive component 52 is located on the same side of the lifting seat 51 along the second direction Y. The aforementioned first clamp 2 can be connected to the side of the top plate 11 facing the bottom plate 12, and the lifting seat 51 moves up and down between the first clamp 2 and the bottom plate 12.

[0040] Furthermore, in some embodiments, the lifting seat 51 includes a plate 511, a first positioning member 512, and a second positioning member 513. The first positioning member 512 and the second positioning member 513 are connected to the top of the plate 511 and are respectively located on the edges of adjacent sides of the plate 511. Specifically, the first positioning member 512 is located on the edge of the plate 511 along the second direction Y, and the second positioning member 513 is located on the edge of the plate 511 along the first direction X. The first positioning member 512 and the second positioning member 513 can position the pad printing plate 8, accurately defining the placement position of the pad printing plate 8 on the plate 511, thereby improving the accuracy and reliability of the pad printing head 7 adjustment.

[0041] For example, the plate 511 can be constructed as a flat plate structure, such as a rectangular flat plate structure. For example, the first positioning member 512 and the second positioning member 513 can be constructed as strip structures.

[0042] Furthermore, in some embodiments, the lifting seat 51 includes a magnetic suction element embedded within the plate 511. The magnetic suction element attracts and fixes the pad printing steel plate 8, further ensuring the accuracy of the position of the pad printing steel plate 8 under the cooperative action of the first positioning element 512 and the second positioning element 513; moreover, the magnetic suction element is highly efficient and simple to operate. Exemplarily, multiple magnetic suction elements can be provided, and these multiple magnetic suction elements can be evenly or unevenly spaced on the plate 511. Exemplarily, the magnetic suction element can be a magnet.

[0043] Furthermore, such as Figures 2-4 As shown, the second clamp 3 includes a clamp body 31 and a crossbeam 32 connected together. The clamp body 31 is used to achieve a detachable connection with the first clamp 2. In some embodiments, the second clamp 3 includes the aforementioned second clamping portion, which is disposed on the clamp body 31 and located on the side of the clamp body 31 away from the crossbeam 32. The crossbeam 32 extends along a first direction X, and the adjusting assembly 4 is adjustablely mounted on the crossbeam 32 along the first direction X.

[0044] Multiple adjustment components 4 can be provided, and the multiple adjustment components 4 are arranged at intervals along the first direction X on the crossbeam 32, preferably at uniform intervals.

[0045] Specifically, the adjusting assembly 4 includes a first adjusting member 41 and a first locking member. The first adjusting member 41 is adjustablely connected to the crossbeam 32 along the first direction X. The first locking member passes through the first adjusting member 41 and / or the crossbeam 32. The first locking member is used to restrict or allow the relative movement of the first adjusting member 41 and the crossbeam 32. Preferably, the first direction X intersects the height direction Z, or is perpendicular to the height direction Z. In this embodiment, the crossbeam 32 of the second clamp 3 and the first adjusting member 41 are adjustable along the first direction X, thereby adjusting the position of the rubber head 7 in the first direction X; and cooperating with the first locking member to achieve quick fixation. When the first locking member is not locked, the first adjusting member 41 is allowed to move relative to the crossbeam 32. At this time, by adjusting the installation position of the first adjusting member 41 along the first direction X on the crossbeam 32, the position of the rubber head 7 in the first direction X is adjusted. After adjustment, the first locking member is locked, thereby restricting the relative movement of the first adjusting member 41 and the crossbeam 32, and achieving fixation of both.

[0046] In some embodiments, the first locking member passes through the first adjusting member 41. For example, as shown... Figure 3 and Figure 4 As shown, the first adjusting member 41 has a first sliding groove 411 and a first hole 412. The first sliding groove 411 extends along the first direction X and is located at the top of the first adjusting member 41. The crossbeam 32 is slidably connected to the first sliding groove 411. The first hole 412 is a through hole provided on one side of the first adjusting member 41 along the second direction Y, and the first hole 412 communicates with the first sliding groove 411. The first hole 412 is provided with an internal thread, and the first locking member can be a screw, bolt, etc., and the first locking member is threadedly connected to the first hole 412. When the first locking member is tightened, the first locking member presses against the crossbeam 32, thereby restricting the relative movement of the first adjusting member 41 and the crossbeam 32; when the first locking member is loosened, the first adjusting member 41 and the crossbeam 32 can move relative to each other along the first direction X.

[0047] In some embodiments not shown in the figures, the first locking member passes through the crossbeam 32. Exemplarily, the crossbeam 32 is also provided with a first hole 412 communicating with the first slide groove 411. The first locking member is threaded into the first hole 412 and presses against the first adjusting member 41 when tightened, thereby restricting the relative movement of the first adjusting member 41 and the crossbeam 32.

[0048] Alternatively, in some embodiments not shown in the figures, the first locking member passes through the first adjusting member 41 and the crossbeam 32. Exemplarily, both the first adjusting member 41 and the crossbeam 32 are provided with first holes 412, and the first holes 412 of both are directly opposite each other. The first locking member passes through and is threadedly connected to the first holes 412 of the first adjusting member 41 and the crossbeam 32, thereby restricting the relative movement of the first adjusting member 41 and the crossbeam 32.

[0049] For example, the adjusting assembly 4 may further include a tensioning piece 42, which is located on the side of the first slide groove 411 near the first hole 412 and connected to the groove wall of the first slide groove 411. In this case, when the first locking member is tightened, the first locking member abuts against the tensioning piece 42, and the tensioning piece 42 is used to press the crossbeam 32 against it.

[0050] For example, the tensioning plate 42 is provided with at least one protrusion 421, and the inner wall of the first sliding groove 411 is provided with at least one second hole 413. The protrusion 421 is embedded in the second hole 413 to prevent the tensioning plate 42 from moving and to ensure the reliability of the fixation between the first adjusting member 41 and the crossbeam 32. The number of protrusions 421 and second holes 413 is the same, and there may be one, two, three or other numbers of protrusions 421 and second holes 413.

[0051] Further, in some embodiments, the adjusting component 4 includes a second adjusting member 43 and a second locking member 44. The second adjusting member 43 is adjustablely connected to the first adjusting member 41 along the second direction Y. The second locking member 44 passes through the first adjusting member 41 and / or the second adjusting member 43; the second locking member 44 is used to restrict or allow relative movement between the first adjusting member 41 and the second adjusting member 43. The second direction Y intersects with the first direction X and the height direction Z; preferably, the second direction Y is perpendicular to both the first direction X and the height direction Z. In this embodiment, the addition of the second adjusting member 43 enables adjustment of the rubber head 7 in the second direction Y, and works with the second locking member 44 to achieve rapid fixation. The first adjusting member 41 and the second adjusting member 43 cooperate to adjust the position of the rubber head 7 in two-dimensional space, improving the accuracy of adjustment. When the second locking member 44 is not locked, the first adjusting member 41 and the second adjusting member 43 are allowed to move relative to each other. At this time, by adjusting the relative position of the second adjusting member 43 and the first adjusting member 41 along the second direction Y, the position of the adjusting head 7 in the second direction Y is achieved. After the adjustment is completed, the second locking member 44 is locked, thereby restricting the relative movement of the first adjusting member 41 and the second adjusting member 43, and fixing the two together.

[0052] In some embodiments, the second locking member 44 passes through the first adjusting member 41. For example... Figure 3 and Figure 4As shown, exemplarily, the second adjusting member 43 is provided with a second sliding groove 431, which extends along the second direction Y and is located at the top of the second adjusting member 43. The bottom of the first adjusting member 41 is slidably connected to the second sliding groove 431. The first adjusting member 41 is provided with a third hole 414 and a fourth hole 415, which intersect and communicate with each other, and the fourth hole 415 communicates with the second sliding groove 431. The third hole 414 is provided with an internal thread, and the second locking member 44 can be a screw, bolt, etc., and the second locking member 44 is threadedly connected to the third hole 414. The fourth hole 415 is provided with a tensioning post 46, which can abut against the groove wall of the second sliding groove 431 through the fourth hole 415. When the second locking member 44 is tightened, the second locking member 44 abuts against the tensioning post 46, and the tensioning post 46 abuts against the groove wall of the second sliding groove 431. At this time, the second locking member 44 uses the tensioning column 46 to press against the second adjusting member 43, restricting the relative movement of the first adjusting member 41 and the second adjusting member 43. When the second locking member 44 is loosened, the first adjusting member 41 and the second adjusting member 43 can move relative to each other.

[0053] In some embodiments not shown in the figures, the first locking member may also be inserted into the second adjusting member 43, or into the first adjusting member 41 and the second adjusting member 43, as long as the setting position of the third hole 414 or the fourth hole 415 is adjusted accordingly, which will not be described in detail here.

[0054] Further, in some embodiments, the adjusting assembly 4 includes a third adjusting member 45 and a third locking member. The third adjusting member 45 is used to connect with the adhesive head 7, and the third adjusting member 45 is adjustablely connected to the second adjusting member 43 along the height direction Z. The third locking member passes through the second adjusting member 43 and / or the third adjusting member 45. The third locking member is used to restrict or allow relative movement between the second adjusting member 43 and the third adjusting member 45. In this embodiment, the addition of the third adjusting member 45 realizes the adjustment of the height direction Z of the adhesive head 7, and works with the third locking member to achieve quick fixation. The first adjusting member 41, the second adjusting member 43, and the third adjusting member 45 cooperate to realize the adjustment of the position of the adhesive head 7 in three-dimensional space, further improving the accuracy of adjustment. When the third locking member is not locked, the relative movement between the second adjusting member 43 and the third adjusting member 45 is allowed. At this time, by adjusting the relative position of the second adjusting member 43 and the third adjusting member 45 along the height direction Z, the position of the adhesive head 7 in the height direction Z is adjusted. Once the adjustment is complete, the third locking member locks in place, thereby restricting the relative movement of the second adjusting member 43 and the third adjusting member 45, thus fixing them in place.

[0055] In some embodiments, the third locking member passes through the second adjusting member 43. For example... Figure 3 and Figure 4As shown, exemplarily, the second adjusting member 43 has a fifth hole 432 on one side along the second direction Y, and a sixth hole at its bottom. The fifth hole 432 intersects with and communicates with the sixth hole. The sixth hole is a non-circular hole, which can be a square hole, a polygonal hole, etc. The third adjusting member 45 includes a connected rod portion 451 and a connecting portion 452. The rod portion 451 is a non-circular rod, which can be a square rod, a polygonal rod, etc. The rod portion 451 is movably inserted into the sixth hole along the height direction Z, and its shape is adapted to the shape of the sixth hole. The fifth hole 432 has an internal thread, and the third locking member can be a screw, bolt, etc., threadedly connected to the fifth hole 432. When the third locking member is tightened, it abuts against the rod portion 451 inserted into the sixth hole, thereby locking the second adjusting member 43 and the third adjusting member 45 and restricting the relative movement of the first adjusting member 41 and the second adjusting member 43. When the second locking member 44 is loosened, the rod portion 451 can move along the sixth hole, thereby allowing the first adjusting member 41 and the second adjusting member 43 to move relative to each other. Exemplarily, the connecting portion 452 can be constructed as a plate-like structure, used to connect the rubber head 7, such as by fasteners like bolts or self-tapping screws, or by welding.

[0056] In some embodiments not shown in the figures, the third locking member may also be inserted into the third adjusting member 45, or into the third adjusting member 45 and the second adjusting member 43, as long as the setting position of the fifth hole 432 or the sixth hole is adjusted accordingly, which will not be described in detail here.

[0057] For example, such as Figure 4 The first adjusting member 41 can be in the form of an "X" shaped frame, the second adjusting member 43 can be in the form of a "Y" shaped frame, and the third adjusting member 45 can be in the form of a "T" shaped frame.

[0058] The installation process of the adjustment component 4 of this utility model is as follows: the rubber head 7 is installed on the connecting part 452 of the third adjustment component 45, the rod part 451 of the third adjustment component 45 is inserted into the sixth hole of the second adjustment component 43, and the third locking member passes through the fifth hole 432 and presses against the rod part 451; the second adjustment component 43 and the first adjustment component 41 are slidably connected in the second direction Y. After being adjusted to the required position, the second locking member 44 presses against the tensioning column 46 through the third hole 414 and the fourth hole 415 to fix it; the first adjustment component 41 and the crossbeam 32 are slidably connected in the first direction X. After being adjusted to the required position, the first locking member passes through the first hole 412 to press against the tensioning piece 42 to fix it.

[0059] In some embodiments, the alignment mechanism further includes a target element that is positioned relative to the pad printing pattern on the pad printing plate 8 in the height direction Z. The target element indicates the position of the pad printing pattern on the pad printing plate 8, facilitating visual positioning of the pad printing head 7 and improving adjustment accuracy. For example, the target element may be a crosshair laser target.

[0060] The application process of the alignment mechanism of this utility model is as follows:

[0061] The first clamp 2 pneumatically clamps the second clamp 3; wherein, the second clamp 3 is equipped with an adjustment component 4 and a rubber head 7.

[0062] The pad printing steel plate 8 is placed on the lifting seat 51; wherein the position of the pad printing steel plate 8 is determined by the first positioning member 512 and the second positioning member 513, and the pad printing steel plate 8 is magnetically fixed by the magnetic suction member.

[0063] The lifting drive component 52 is used to raise the lifting seat 51 to the position of the rubber head 7.

[0065] According to an embodiment of the present invention, another aspect provides a pad printing apparatus, including a pad printing mechanism and the aforementioned alignment mechanism. For example... Figure 5 As shown, the pad printing mechanism includes a third clamp 6, which is detachably connected to the second clamp 3. This invention utilizes an alignment mechanism to adjust the position of the printing head 7 offline. When changing the pad printing pattern, the original second clamp 3 on the pad printing mechanism is removed and replaced with the second clamp 3 that has been aligned offline, thus completing the changeover. This process significantly shortens the changeover time, thereby reducing downtime of the pad printing equipment and improving product production efficiency.

[0066] In some embodiments, the pad printing mechanism includes a second pneumatic actuator, and the third clamp 6 includes a third clamping portion. The second pneumatic actuator is connected to the third clamping portion and / or the second clamping portion, and is used to drive the third clamping portion and the second clamping portion to clamp and release each other. The second pneumatic actuator has the same structure as the first pneumatic actuator, and the third clamping portion has the same structure as the second clamping portion, which will not be described further here.

[0067] The replacement process of the pad printing device of this utility model is as follows:

[0068] Alignment mechanism: Place the pad printing steel plate 8 on the lifting seat 51; install the second clamp 3 on the first clamp 2; the lifting seat 51 drives the pad printing steel plate 8 to rise; adjust the position of the glue head 7; remove the second clamp 3 for later use.

[0069] Pad printing mechanism: Remove the original pad printing steel plate 8; remove the original second clamp 3; install the second clamp 3, which has been aligned and removed from the alignment mechanism, onto the third clamp 6; install the corresponding pad printing steel plate 8.

[0070] In practice, the alignment mechanism of this invention operates smoothly with a repeatability accuracy within ±0.1mm. The pad printing mechanism also operates smoothly with a repeatability accuracy within ±0.1mm. The changeover efficiency of the pad printing device is significantly improved, with a changeover CT time (Cycle Time, the total time required to complete one product or service) ≤5min; and the machine uptime of the pad printing device is significantly improved, with an uptime ≥98% (excluding the influence of material factors).

[0071] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
