Description

Technical Field

[0001] The invention belongs to the technical field of hot stamping equipment, and in particular relates to an automatic hot stamping machine for producing cosmetic packaging bottles. Background Art

[0002] The hot stamping process uses the principle of heat transfer to transfer the aluminum layer from anodized aluminum to the substrate surface, creating a unique metallic effect. Because the primary material used for hot stamping is anodized aluminum foil, hot stamping is also called anodized aluminum hot stamping. Anodized aluminum foil is typically composed of multiple layers of material, with a base material often consisting of polyethylene (PE), followed by a release coating, a color coating, a metal coating (aluminum plating), and an adhesive coating.

[0003] In the processing of cosmetic packaging bottles, in order to increase the added value of the product, hot stamping is usually used to decorate the surface of the cosmetic packaging bottles with gold patterns. However, existing hot stamping machines generally require manual loading and unloading operations, and the hot stamping efficiency is low. In particular, for cosmetic packaging bottles that require multiple patterns to be hot stamped, after manual loading, the cosmetic packaging bottles need to be manually rotated to correct the hot stamping position, which further reduces the hot stamping efficiency and the accuracy of the hot stamping position correction is also poor. To this end, the present application provides a fully automated hot stamping machine for the production of cosmetic packaging bottles, based on the premise of realizing automatic hot stamping processing of cosmetic packaging bottles and improving hot stamping processing efficiency.

It should be understood that the numbers used in this way are interchangeable where appropriate for the embodiments of the present application described herein. Example 1

[0022] like Figure 1 As shown, the automatic hot stamping machine for producing cosmetic bottle packaging bottles provided by the present invention includes a feeding mechanism 100, a feeding mechanism 200, a detection mechanism 300, a hot stamping mechanism 400 and a discharging mechanism 500.

[0023] Continue to refer Figure 1 As shown, in the automatic hot stamping machine of the present invention, the feeding mechanism 200 is set to a rotary cycle feeding, and the feeding station a, the feeding detection station b, the hot stamping station c, the discharging detection station d and the discharging station e are arranged in a manner around the central axis of rotation of the feeding mechanism 200 (as shown in FIG. Figure 4 shown).

[0024] Continue to refer Figure 4As shown, the feeding mechanism 200 includes a feeding base plate 201, a positioning module 202 and a driving module. Five positioning modules 202 are installed on the feeding base plate 201 to respectively correspond to the above-mentioned five workstations. Specifically: the driving module drives the feeding base plate 201 to rotate through the main driving component 203; the driving module also drives the positioning module 202 to rotate through the auxiliary driving component 204. In this embodiment, the main driving component 203 preferably adopts a stepping motor installed on the frame, the auxiliary driving component 204 preferably adopts a stepping motor installed on the back side of the feeding base plate 201, and the positioning module 202 is as shown in FIG. Figure 5 The main rod 2021 shown includes a positioning sleeve 2026 on the outside, and the end of the positioning sleeve 2026 forms a positioning inclined surface 2027 that abuts against the opening of the workpiece.

[0025] Based on the above-mentioned feeding mechanism 200, the automated hot stamping process of the automatic hot stamping machine of this embodiment is described in detail as follows: (1) Automatic feeding Continue to refer Figure 2 and Figure 3 As shown, the feeding mechanism 100 includes a feeding conveyor belt 101, a feeding guide rail 102, a feeding push plate 103 and a feeding drive mechanism 104; the feeding guide rail 102 includes a base 1021 and a track 1022 that can be raised and lowered relative to the base 1021, and a V-shaped guide groove 1023 is provided on the top of the track 1022; the feeding push plate 103 is driven by the feeding drive mechanism 104 to move back and forth in the V-shaped guide groove 1023.

[0026] The cosmetic packaging bottles (hereinafter referred to as workpieces) are placed on the feed conveyor belt 101 in a manner such that the central axis thereof is parallel to the feed guide rail 102 . Figure 2 In the process, the feed conveyor belt 101 conveys the workpiece from left to right ( Figure 1 The feeding mechanism 100 realizes feeding from right to left) until the rearmost workpiece falls into the V-shaped guide groove 1023 at the top of the track 1022. The feeding drive mechanism 104 (a linear track drive mechanism as shown in the figure) is activated to push the feeding push plate 103 to move in the V-shaped guide groove 1023, and push the workpiece in the V-shaped guide groove 1023 until the workpiece is inserted into the main rod 2021 located at the feeding station a. At the same time, the push of the feeding push plate 103 also makes the opening of the workpiece contact the positioning inclined surface 2027 at the end of the positioning sleeve 2026, thereby achieving positioning of the workpiece during the feeding process.

[0027] In addition, during the overall automatic loading process, the track 1022 can also be raised and lowered relative to the base 1021 through manual adjustment (such as a manual adjustment screw) or automatic adjustment (such as an electric adjustment screw), thereby changing the height of the track 1022 relative to the feeding station a, ensuring that after the workpiece falls into the V-shaped guide groove 1023, its center axis is at the same height as the center of the feeding station a, that is, the center axis of the workpiece and the center axis of the main rod 2021 at the feeding station a are on the same straight line, thereby ensuring that the workpiece can be smoothly inserted into the main rod 2021, and enabling the overall feeding mechanism 100 to flexibly adapt to the automatic loading of workpieces of different diameters.

[0028] In addition, the end of the main rod 2021 is set to a conical structure or an arc structure to achieve automatic guidance when loading the workpiece.

[0029] (2) Automatic positioning detection Continue to refer Figure 4 As shown, the detection mechanism 300 includes a feed detection module that is arranged at the feed detection station. The figure shows that the feed detection module includes a mounting support and a detection camera fixed on the mounting support.

[0030] After the workpiece is automatically loaded using the feeding mechanism 100, the main drive assembly 203 drives the feeding base plate 201 to rotate counterclockwise, so that the workpiece is transferred from the feeding station to the feeding inspection station. At the feeding inspection station: the auxiliary drive assembly 204 drives the main rod 2021 with the workpiece inserted therein to rotate: The main rod 2021 and the workpiece initially rotate through at least 360°. During this rotation, a detection camera captures an image of the workpiece surface and transmits the captured image to a processing system connected to the automatic hot stamping machine. The processing system processes the image to determine the angular difference between the workpiece's current positioning angle and the target hot stamping angle. Based on this angular difference, the auxiliary drive assembly 204 then drives the main rod 2021 for rotational correction, thereby achieving automatic positioning correction of the workpiece. Workpiece positioning through image processing is a well-known technique (e.g., comparing a captured image with a standard positioning image to obtain an angular difference) and will not be described in detail here.

[0031] (3) Automatic hot stamping Continue to refer Figure 9 As shown, the hot stamping mechanism 400 includes a foil conveying module 401, a hot stamping head module 402, and a hot stamping support module 403. The hot stamping head module 402 and the hot stamping support module 403 are respectively located on the upper and lower sides of the hot stamping station. In this embodiment, the hot stamping mechanism 400 adopts a round-pressing flat hot stamping structure, but the present disclosure is not limited to this. In other embodiments of the present disclosure, the hot stamping mechanism 400 may also adopt a round-pressing round hot stamping structure or a flat-pressing flat hot stamping structure.

[0032] Figure 10 The foil film conveying module 401 is shown to include a discharge roller 4011, a guide roller 4012, and a winding roller 4013. The guide rollers 4012 are symmetrically arranged on the left and right sides of the hot stamping station to enable the hot stamping foil film to be horizontally conveyed at the hot stamping station.

[0033] Figure 11 The ironing head module 402 shown on the upper side of the hot stamping station includes a Z-axis lifting mechanism 4021, a Y-axis moving mechanism 4022, an X-axis moving mechanism 4023, and an ironing head 4024, which are connected in sequence. In this embodiment, the ironing head 4024 adopts a flat structure. The Z-axis lifting mechanism 4021 preferably adopts a linear Z-axis lifting motor. The Y-axis moving mechanism 4022 and the X-axis moving mechanism 4023 both include a drive motor, a lead screw, a nut, a guide rail, and other structures, thereby enabling the ironing head 4024 to achieve flexible linear movement along the Z, Y, and X axes.

[0034] Figure 12 The hot stamping support module 403, shown below the hot stamping station, includes hot rollers 4032 that are raised and lowered by a lifting cylinder 4031. In the figure, the lifting cylinder 4031 is fixed to a bracket. A mounting base is fixed to the top of the lifting cylinder 4031, and two hot rollers 4032 are rotatably mounted on the mounting base. Auxiliary telescopic guides are also connected between the mounting base and the bracket to ensure stable lifting and lowering of the hot rollers 4032.

[0035] After the automatic positioning detection and correction are completed by the feed detection module of the detection mechanism 300 and the auxiliary drive component 204 of the feeding mechanism 200, the main drive component 203 drives the feeding base plate 201 to rotate counterclockwise, so that the workpiece is transferred from the feed detection station to the hot stamping station.

[0036] At the hot stamping station: the two guide rollers 4012 are used to limit the hot stamping foil and ensure that it can be attached to the surface of the workpiece; the Z-axis lifting mechanism 4021 drives the hot stamping head 4024 to descend until it is pressed on the top surface of the hot stamping foil, and the lifting cylinder 4031 drives the hot stamping roller 4032 to rise until it contacts the bottom of the workpiece; the X-axis moving mechanism 4023 drives the hot stamping head 4024 to move to the right, and the auxiliary drive component 204 drives the main rod 2021 and the workpiece to rotate clockwise between the two hot stamping rollers 4032 to complete the hot stamping.

[0037] After completing one round of hot stamping, the hot stamping head 4024 and the hot stamping roller 4032 are both moved back to their original positions, and the hot stamping foil film is wound up by the winding roller 4013, thereby ensuring that the hot stamping foil film can be effectively kept in a flat state.

[0038] As mentioned above, the Y-axis movement 4022 is mainly used to adjust the hot stamping head 4024 and the corresponding hot stamping position along the axial direction of the workpiece to flexibly adapt to the hot stamping requirements of different positions.

[0039] (4) Automatic quality inspection Continue to refer Figure 4 As shown, the detection mechanism 300 includes a discharge detection module that is arranged at the discharge detection station. The figure shows that the discharge detection module includes a mounting support and a detection camera fixed on the mounting support.

[0040] After the workpiece is stamped using the stamping mechanism 400, the main drive assembly 203 drives the feed base plate 201 to rotate counterclockwise, so that the workpiece is transferred from the stamping station to the discharge inspection station. At the discharge inspection station: the auxiliary drive assembly 204 drives the main rod 2021 with the workpiece inserted therein to rotate: The main rod 2021 and the workpiece initially rotate through at least 360°. During this rotation, an inspection camera captures an image of the workpiece surface and transmits the captured image to a processing system connected to the automatic hot stamping machine. The processing system processes the image to determine whether the target pattern stamped on the workpiece surface is qualified (this determination corresponds to the subsequent discharge of the discharge mechanism 500), thereby achieving quality inspection of the workpiece. The use of image processing to inspect the workpiece surface is a known technique (e.g., comparing a captured image with a standard positioning image to determine whether the captured pattern is qualified) and will not be described in detail here.

[0041] (5) Automatic discharging Continue to refer Figure 13 As shown, the discharging mechanism 500 includes a discharging conveyor belt 501, a discharging slide 502 and a discharging drive mechanism 503; a negative suction head 504 capable of performing negative suction on the workpiece at the discharging station is fixedly installed on the discharging slide 502, and the discharging drive mechanism 503 drives the discharging slide 502 to move back and forth so that the workpiece can be transferred from the discharging station to the discharging conveyor belt 501.

[0042] Discharging mechanism 500 Figure 1 The illustrated mounting position cooperates with the feed mechanism 200, ensuring that the reciprocating path of the discharge carriage 502 is parallel to the central axis of the main rod 2021. Consequently, when the discharge carriage 502 is driven toward the discharge station by the discharge drive mechanism 503 (e.g., a linear track-type drive mechanism shown in the figure), the negative suction head 504 contacts the end of the workpiece, thereby enabling negative suction of the workpiece. When the discharge carriage 502 returns to above the discharge conveyor 501, the negative suction head 504 releases the negative suction, allowing the workpiece to fall onto the discharge conveyor 501, thereby achieving automatic discharge of the workpiece after hot stamping.

[0043] In addition, a material separation mechanism is provided on the discharge conveyor belt 501, which separates the workpieces according to the detection results of the above-mentioned discharge detection module. The width of the discharge conveyor belt 501 is preferably set to be suitable for only one workpiece to pass through. The material separation mechanism includes a push cylinder and a material separation port respectively provided on both sides of the discharge conveyor belt 501. In addition, a defective product box is provided below the material separation port, and a secondary discharge conveyor belt is provided at the discharge end of the discharge conveyor belt 501. Thus: When the quality inspection result is unqualified (for example, there are stains on the hot stamping pattern), the corresponding workpiece on the discharge conveyor 501 is pushed to the material distribution port by the pushing cylinder, so that the unqualified workpiece falls into the defective box; When the quality inspection result is qualified, the push cylinder is not started, and the qualified workpiece is transported to the secondary discharge conveyor through the discharge conveyor 501 to facilitate the conveyance of the qualified workpiece to the next processing step.

[0044] Example 2 (This example is based on the above example 1) like Figure 1 As shown, the automatic hot stamping machine for producing cosmetic bottle packaging bottles provided by the present invention includes a feeding mechanism 100, a feeding mechanism 200, a detection mechanism 300, a hot stamping mechanism 400 and a discharging mechanism 500.

[0045] Continue to refer Figure 1 As shown, in the automatic hot stamping machine of the present invention, the feeding mechanism 200 is set to rotary circular feeding, and the feeding station a, feeding detection station b, hot stamping station c, discharging detection station d and discharging station e are arranged around the central axis of rotation of the feeding mechanism 200.

[0046] Continue to refer Figure 4 As shown, the feeding mechanism 200 includes a feeding base plate 201, a positioning module 202 and a driving module. Five positioning modules 202 are installed on the feeding base plate 201 to respectively correspond to the above-mentioned five workstations. Specifically: the driving module drives the feeding base plate 201 to rotate through the main driving component 203; the driving module also drives the positioning module 202 to rotate through the auxiliary driving component 204. In this embodiment, the main driving component 203 is preferably a stepper motor installed on the frame; the auxiliary driving component 204 is preferably installed on the frame and forms a detachable assembly connection with the positioning module 202; the positioning module 202 is as shown Figure 5 The main rod 2021 shown includes a positioning sleeve 2026 on the outside, and the end of the positioning sleeve 2026 forms a positioning inclined surface 2027 that abuts against the opening of the workpiece.

[0047] Continuing with reference to Figure 8 , the auxiliary drive assembly 204 includes a drive cylinder 2041, a guide rail 2042, a slide 2043, a drive motor 2044, a connecting plug 2045, and a connecting sleeve 2046. The slide 2043 is slidably mounted on the guide rail 2042 and driven for movement by the drive cylinder 2041. The connecting plug 2045 is rotatably mounted on the slide 2043 and driven for rotation by the drive motor 2044. The main rod 2021 is rotationally damped and mounted on the feed base 201 via a connecting sleeve 2046. The connecting sleeve 2046 defines a cavity capable of inserting at least a portion of the connecting plug 2045. In this embodiment, the auxiliary drive assembly 204 is installed only at the corresponding feed inspection station, the hot stamping station, and the discharge inspection station, while a connecting sleeve 2046 is fixedly mounted on each main rod 2021.

[0048] Based on the above-mentioned feeding mechanism 200, the automated hot stamping process of the automatic hot stamping machine of this embodiment is described in detail as follows: (1) Automatic feeding: The feeding method is the same as that of the above embodiment 1.

[0049] (2) Automatic positioning detection After the workpiece is automatically loaded by the feeding mechanism 100, the main driving assembly 203 drives the feeding base plate 201 to rotate counterclockwise, so that the workpiece is transferred from the feeding station to the feeding inspection station. At the feeding inspection station: the slide 2043 is driven on the guide rail 2042 by the driving cylinder 2041. Figure 5 The connecting plug 2045 is moved to the right side in the middle of the connecting rod 2021, thereby making the connecting plug 2045 approach the connecting sleeve 2046 and driving the connecting plug 2045 to be inserted into the plug cavity in the connecting sleeve 2046, thereby completing the connection between the auxiliary drive assembly 204 and the main rod 2021 at the feeding detection station; then the connecting plug 2045, the connecting sleeve 2046 and the main rod 2021 with the workpiece inserted therein are driven by the driving motor 2044 to rotate: In an executable implementation of this embodiment, in order to improve the stability of the driving motor 2044 when driving the main rod 2021 and the workpiece to rotate, the Figure 6 As shown, a negative suction cavity 2028 is opened inside the main rod 2021, and a negative pressure generator 2047 is fixedly installed on the slide 2043, and the negative pressure generator 2047 is connected to a negative suction channel that can pass through the connecting plug 2045 and the connecting sleeve 2046 and communicate with the negative suction cavity 2028 (that is, the connecting plug 2045 and the connecting sleeve 2046 are preferably set as hollow structures).

[0050] In this embodiment, if Figure 8As shown, the driving motor 2044 and the connecting plug 2045 are connected by a meshing gear set. The connecting plug 2045 is rotatably mounted on the negative pressure generator 2047 (and connects the negative suction channel with the negative pressure generator 2047). The driving motor 2044 is fixedly mounted on the slide 2043. The output shaft of the driving motor 2044 is connected to a driving gear, and the external sleeve of the connecting plug 2045 is provided with a driven gear sleeve. Therefore, when the driving motor 2044 is started, the driving gear is driven to rotate, and the driving gear and the driven gear sleeve are meshed with each other, thereby driving the connecting plug 2045 to rotate. At the same time, the negative pressure generator 2047 is started to form a negative pressure in the negative suction channel and the negative suction chamber 2028, and combined with Figure 6 As shown, the negative suction cavity 2028 is connected to the internal space of the workpiece through the port at the end of the main rod 2021, so that the workpiece is fixed on the main rod 2021 by negative suction, thereby improving the connection stability between the main rod 2021 and the workpiece during rotation.

[0051] The main rod 2021 and the workpiece initially rotate through at least 360°. During this rotation, a detection camera captures an image of the workpiece surface and transmits the captured image to a processing system connected to the automatic hot stamping machine. The processing system processes the image to determine the angular difference between the workpiece's current positioning angle and the target hot stamping angle. Based on this angular difference, the auxiliary drive assembly 204 then drives the main rod 2021 for rotational correction, thereby achieving automatic positioning correction of the workpiece. Workpiece positioning through image processing is a well-known technique (e.g., comparing a captured image with a standard positioning image to obtain an angular difference) and will not be described in detail here.

[0052] After completing the rotation positioning detection and rotation positioning correction, the negative pressure generator 2047 and the drive motor 2044 are turned off, and the slide 2043 is driven to move on the guide rail 2042 by the drive cylinder 2041. Figure 5 Move to the left side in the middle, so that the connecting plug 2045 is withdrawn from the connecting socket 2046, completing the disassembly of the auxiliary drive assembly 204 and the main rod 2021, so that the feeding base plate 201 can be restored to a rotatable state.

[0053] (3) Automatic hot stamping After the automatic positioning detection and correction are completed by the feed detection module of the detection mechanism 300 and the auxiliary drive component 204 of the feeding mechanism 200, the main drive component 203 drives the feeding base plate 201 to rotate counterclockwise, so that the workpiece is transferred from the feed detection station to the hot stamping station.

[0054] At the hot stamping station: The two guide rollers 4012 are used to ensure that the hot stamping foil can be attached to the surface of the workpiece. The Z-axis lifting mechanism 4021 drives the hot stamping head 4024 down to press on the top surface of the hot stamping foil. The lifting cylinder 4031 drives the hot stamping roller 4032 up to contact the bottom of the workpiece. The slide 2043 is driven to move on the guide rail 2042 by driving the cylinder 2041, thereby connecting the auxiliary driving assembly 204 and the main rod 2021; By activating the negative pressure generator 2047 to generate negative pressure in the negative suction chamber 2028, the workpiece is negatively sucked and fixed on the main rod 2021; The ironing head 4024 is driven to move rightward by the X-axis moving mechanism 4023, and the main rod 2021 and the workpiece are driven to rotate clockwise between the two ironing rollers 4032 by the driving motor 2044, thereby completing the hot stamping.

[0055] After completing one hot stamping operation, the negative pressure generator 2047 and the drive motor 2044 are turned off, the hot stamping head 4024, the hot stamping roller 4032 and the slide 2043 are all moved back to their original positions, and the hot stamping foil is wound up by the winding roller 4013 to ensure that the hot stamping foil can be effectively kept in a flat state.

[0056] (4) Automatic quality inspection After the workpiece is stamped using the hot stamping mechanism 400, the main drive assembly 203 drives the feed base plate 201 to rotate counterclockwise, transferring the workpiece from the hot stamping station to the discharge inspection station. At the discharge inspection station: the cylinder 2041 is driven to move the slide 2043 on the guide rail 2042 to connect the auxiliary drive assembly 204 to the main rod 2021; the negative pressure generator 2047 is activated to create a negative pressure in the negative suction chamber 2028, thereby negatively sucking and fixing the workpiece to the main rod 2021; the motor 2044 is driven to rotate the connecting plug 2045, the connecting socket 2046, and the main rod 2021 with the workpiece inserted therein: The main rod 2021 and the workpiece initially rotate through at least 360°. During this rotation, an inspection camera captures an image of the workpiece surface and transmits the captured image to a processing system connected to the automatic hot stamping machine. The processing system processes the image to determine whether the target pattern stamped on the workpiece surface is qualified (this determination corresponds to the subsequent discharge of the discharge mechanism 500), thereby achieving quality inspection of the workpiece. The use of image processing to inspect the workpiece surface is a known technique (e.g., comparing a captured image with a standard positioning image to determine whether the captured pattern is qualified) and will not be described in detail here.

[0057] (5) Automatic discharging: The discharging method is the same as that of the above embodiment 1.

[0058] Example 3 (This example is based on the above example 2) like Figure 1 As shown, the automatic hot stamping machine for producing cosmetic bottle packaging bottles provided by the present invention includes a feeding mechanism 100, a feeding mechanism 200, a detection mechanism 300, a hot stamping mechanism 400 and a discharging mechanism 500.

[0059] Continue to refer Figure 1 As shown, in the automatic hot stamping machine of the present invention, the feeding mechanism 200 is set to rotary circular feeding, and the feeding station a, feeding detection station b, hot stamping station c, discharging detection station d and discharging station e are arranged around the central axis of rotation of the feeding mechanism 200.

[0060] Continue to refer Figure 4 As shown, the feeding mechanism 200 includes a feed base 201, a positioning module 202, and a drive module. Five positioning modules 202 are mounted on the feed base 201, corresponding to the five aforementioned workstations. Specifically, the drive module rotates the feed base 201 via a main drive assembly 203; the drive module also rotates the positioning modules 202 via a secondary drive assembly 204. In this embodiment, the main drive assembly 203 is preferably a stepper motor mounted on a frame; the secondary drive assembly 204 is preferably mounted on the frame and forms a detachable assembly connection with the positioning modules 202.

[0061] Continue to refer to 6 and Figure 7 As shown, the positioning module 202 includes a main rod 2021, a piston 2022, a telescopic rod 2023 and a positioning sleeve 2026. The telescopic rod 2023 is fixed to one side of the piston 2022, and the telescopic rod 2023 can be retracted into the positioning cavity in the main rod 2021 by the movement of the piston 2022 in the main rod 2021 (combined with Figure 6 As shown, the positioning cavity and the negative suction cavity 2028 do not interfere with each other). The center of the end of the telescopic rod 2023 is recessed to form a positioning groove 2024. The telescopic rod 2023 is provided with an air guide hole 2025 connecting the positioning groove 2024 and the positioning cavity. The positioning sleeve 2026 is fixedly mounted on the outside of the main rod 2021, and the end of the positioning sleeve 2026 forms a positioning inclined surface 2027 that abuts the workpiece opening.

[0062] Based on the above-mentioned feeding mechanism 200, the automated hot stamping process of the automatic hot stamping machine of this embodiment is described in detail as follows: (1) Automatic feeding The driving mechanism 104 drives the feed push plate 103 to move in the V-shaped guide groove 1023 and pushes the workpiece in the V-shaped guide groove 1023, so that the workpiece is inserted into the positioning module 202. During this process, one end of the workpiece will first collide with the end of the telescopic rod 2023, so that a sealed space is formed in the positioning groove 2024; Figure 6 and Figure 7 As shown, as the workpiece moves, the telescopic rod 2023 and the piston 2022 are pushed to the left, so that the telescopic rod 2023 gradually retracts into the inside of the main rod 2021, thereby gradually increasing the space on the left side of the piston 2022, thereby causing a certain degree of negative pressure to be formed in the space on the left side of the piston 2022 and the air guide hole 2025 and the positioning groove 2024, that is, the workpiece will be negatively sucked and positioned at the end of the telescopic rod 2023 until the opening of the workpiece contacts the positioning slope 2027 at the end of the positioning sleeve 2026, thereby realizing the positioning of the workpiece during the loading process.

[0063] As described above, based on the extension and retraction of the telescopic rod 2023, it can be ensured that the workpiece opening can effectively contact the positioning inclined surface 2027 at the end of the positioning sleeve 2026, thereby making the positioning module 202 of this embodiment flexibly applicable to the automatic loading of workpieces of different depths.

[0064] (2) Automatic positioning detection: The detection method is the same as that of the above-mentioned embodiment 2.

[0065] (3) Automatic hot stamping: The hot stamping operation is the same as that in the above-mentioned embodiment 2.

[0066] (4) Automatic quality detection: The detection method is the same as that of the above-mentioned embodiment 2.

[0067] (5) Automatic discharging Discharging mechanism 500 Figure 1 The installation position shown is coordinated with the feeding mechanism 200, that is, it ensures that the reciprocating movement path of the discharge slide 502 is parallel to the central axis of the main rod 2021. Therefore, when the discharge slide 502 is driven to approach the discharge station by the discharge drive mechanism 503 (the linear track drive mechanism shown in the figure), the negative suction head 504 can be made to abut against the end of the workpiece, thereby enabling the negative suction of the workpiece to be achieved with the help of the negative suction head 504.

[0068] When the workpiece is moved toward the discharge conveyor 501 by the negative suction head 504 and the discharge carriage 502, the telescopic rod 2023 moves synchronously with the workpiece through the negative suction in the positioning groove 2024, that is, it can pull the telescopic rod 2023 out of the main rod 2021. During this process, the space on the left side of the piston 2022 gradually decreases, causing the negative pressure in the space on the left side of the piston 2022 and in the air guide hole 2025 and the positioning groove 2024 to gradually decrease until the telescopic rod 2023 returns to its normal position. Figure 6 In the state shown, the negative pressure in the positioning groove 2024 disappears, and the workpiece can be easily separated from the telescopic rod 2023. When the discharge carriage 502 moves back to the top of the discharge conveyor 501, the negative suction head 504 releases the negative suction and the workpiece falls onto the discharge conveyor 501, thereby realizing automatic discharge of the workpiece after hot stamping.

[0069] Preferably, in this embodiment, regarding the sliding between the piston 2022 , the telescopic rod 2023 and the main rod 2021 , damping sliding is provided, thereby effectively achieving automatic positioning of the piston 2022 and the telescopic rod 2023 .

[0070] In summary, the automatic hot stamping machine provided by the present invention can fully automatically realize workpiece loading, feeding, positioning detection, hot stamping, quality inspection and discharge. The entire process does not require manual operation, ensuring the accuracy of the hot stamping position and improving the hot stamping efficiency.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
