Description

A rotating laser cutting mechanism for glassware Technical Field

[0001] This invention relates to the field of glassware processing equipment technology, specifically a rotary glassware laser cutting mechanism. Background Technology

[0002] A glass stemmed glass is a common type of glass vessel used to hold liquids. During its production, after the glass body is demolded and formed in the mold, it needs to be cut in half horizontally by a corresponding cutting device to cut out the mouth of the glass. After cutting, it is divided into finished stemmed glass and waste glass, as shown in Figure 9 in the attached diagram of the instruction manual. In the industry, this is called "crack" or "break".

[0003] Existing patents include Chinese Patent Publication No. CN118270973A, entitled "A P-second Laser Bursting Machine for Glass Cups," which includes: a base frame; mechanical grippers; a loading station; a cutting station with a rotary seat for receiving the glass cup, on which the glass cup rotates around its own axis; a P-second laser arranged on one side of the rotary seat for irradiating the outer surface of the riser line of the glass cup on the rotary seat; a local heating station with a flame torch for heating the cut groove of the glass cup; an inspection station including a detector for inspecting the glass cup; and a unloading station.

[0004] Existing technical solutions include a horizontally arranged turntable that can rotate intermittently. Multiple mechanical grippers are evenly arranged around the circumference of the turntable. A loading station, a laser station, a local heating station, and an unloading station are arranged sequentially along the circumferential trajectory of the turntable. The loading station mainly uses a conveyor belt to transport an inverted glass goblet to the picking position of the mechanical grippers on the turntable. The foot of the glass goblet is positioned in the gripping area of ​​the mechanical grippers by manual operation or lifting equipment. The mechanical grippers hold the foot of the glass goblet tightly. Then, as the turntable rotates, the mechanical grippers reach the laser cutting position of the laser. When the glass goblet is at the laser cutting position, the mechanical grippers cause the glass goblet to rotate, so that the circumference of the glass goblet can be irradiated and cut by the laser, thereby achieving a ring cut to form the mouth of the glass goblet.

[0005] The shortcoming of the existing technology is that, since the glass goblet is rotating during the laser cutting process, the alignment between the axis of the goblet body and the axis of rotation is required to be high. Otherwise, the rim of the goblet may be skewed after cutting. The existing conveyor belt directly transports the goblet, which may result in the axis of the goblet body not being completely aligned with the axis of rotation. In order to ensure good cutting quality of the goblet rim, we propose a new technical solution to improve the above situation. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary glassware laser cutting mechanism to overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A rotary glassware laser cutting mechanism includes a mechanical gripper mounted on a turntable. The mechanical gripper has a material support platform at its loading position. The top of the material support platform has a positioning port that is adapted to be inserted into an inverted glass goblet. The positioning port can keep the extended line of the glass goblet's body axis and the rotation axis of the mechanical gripper on the same straight line. A telescopic drive unit is installed at the bottom of the material support platform. When the telescopic drive unit is extended, it can position the foot of the glass goblet on the material support platform within the gripping area of ​​the mechanical gripper.

[0009] Preferably, the telescopic drive unit includes a through-hole extending through the top of the material support platform, a ball screw sleeve is rotatably installed in the through-hole, a lead screw is adapted to pass through the ball screw sleeve, and a drive motor is driven to the bottom end of the lead screw.

[0010] Preferably, the material support platform includes a platform plate that is connected to the telescopic drive unit. A through opening is provided in the middle of the platform plate, and a rotating ring is rotatably installed in the through opening. The inner ring of the rotating ring forms a positioning opening. The rotating ring is connected to the ball screw sleeve through a transmission component. When the platform plate moves, the rotating ring can drive the glass goblet to rotate axially.

[0011] Preferably, the transmission assembly includes a first annular groove formed on the inner wall of the through-hole, the first annular groove being rotatably engaged with a rotating ring, a circumferential groove connected to the first annular groove being formed on the inner side wall of the through-hole, a first toothed ring being rotatably adapted to be fixedly sleeved with a ball thread sleeve in the circumferential groove, and a second toothed ring being fixedly fitted and meshed with the first toothed ring on the outer circumferential surface of the rotating ring.

[0012] Preferably, a second annular groove is formed on the annular wall of the first annular groove, and a protruding block fixed to the rotating ring is slidably adapted in the second annular groove. A blocking unit located on the movement trajectory line of the protruding block is installed in the second annular groove. When the protruding block contacts the blocking unit, the rotating ring is in a stop-rotation position.

[0013] Preferably, the blocking unit includes a recessed groove formed on the bottom surface of the second annular groove, and a stop post is adapted to be inserted into the recessed groove, the post being located on the movement trajectory line of the protruding block.

[0014] Preferably, one side of the stop post has a notch that allows the protruding block to pass through, and a backstop baffle is movably installed inside the notch. The top of the stop post extends movably out of the top surface of the platform. The stop post and the platform are connected by an elastic reset component. In its natural state, the elastic reset component keeps the post body located on the movement trajectory line of the protruding block.

[0015] Preferably, the elastic reset assembly includes a retaining ring plate located above the platform and fixedly sleeved with the retaining post. The retaining ring plate and the platform are connected and fixedly connected by a first spring, which is movably sleeved on the retaining post.

[0016] Preferably, a base plate is provided directly below the material support platform, a column is fixed on the base plate, and a horizontal stop bar is fixed on the column body. The horizontal stop bar is located on the trajectory line of the column's length direction.

[0017] Preferably, the inner wall of the through-hole is provided with a plurality of evenly distributed pin holes, each pin hole is screwed with a plug post, and each plug post is movably mounted with a universal ball at its end. The center of the circumference formed by the outer ends of each plug post is located on the axis of the through-hole.

[0018] In the above technical solution, the present invention provides a rotary glassware laser cutting mechanism. By providing a material support platform with a positioning port at the loading position of the mechanical gripper, the extended axis of the glass body of the stemmed glass is kept on the same straight line as the rotation axis of the mechanical gripper. Then, the material support platform is moved closer to the mechanical gripper by the push of the telescopic drive unit, so that the foot of the glass stemmed glass on the material support platform is in the gripping area of ​​the mechanical gripper. Throughout the process, it can ensure that the extended axis of the glass body of the stemmed glass is on the same straight line as the rotation axis of the mechanical gripper, which helps to ensure that the rim of the glass has good cutting quality after laser cutting and greatly reduces the occurrence of rim tilting of the glass stemmed glass.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Please refer to Figures 1-9. An embodiment of the present invention provides a rotary glassware laser cutting mechanism, including a mechanical gripper 1 mounted on a turntable. The mechanical gripper 1 has a material support platform 2 at its loading position. The top of the material support platform 2 has a positioning port 3 that is adapted to be inserted into an inverted glass goblet. The positioning port 3 can keep the extended line of the glass goblet's body axis and the rotation axis of the mechanical gripper 1 on the same straight line. The bottom of the material support platform 2 is equipped with a telescopic drive unit 4. When the telescopic drive unit 4 is extended, it can place the foot of the glass goblet on the material support platform 2 into the gripping area of ​​the mechanical gripper 1.

[0033] Specifically, the mechanical gripper 1 has its jaws facing downwards and can rotate axially. The mechanical gripper 1 can hold the stem of the glass goblet. The mechanical gripper 1 is an existing structure and will not be described in detail. The support platform 2 is located directly below the mechanical gripper 1. The platform surface of the support platform 2 is parallel to the horizontal plane. The outline of the positioning port 3 is circular. It should be noted that before the rim of the glass goblet is cut, its body is approximately a frustum. Therefore, the diameter of the positioning port 3 is smaller than the maximum diameter of the lower bottom surface of the frustum of the glass goblet, and the diameter of the positioning port 3 is larger than the minimum diameter of the upper bottom surface of the frustum of the glass goblet. This ensures that the glass goblet can be inserted into the positioning port 3 without falling out, and it plays a role in positioning the verticality of the glass goblet. The output direction line of the telescopic drive unit 4 is parallel to the axis of the positioning port 3. The telescopic drive unit 4 can drive the support platform 2 to move vertically.

[0034] In actual use, when the loading platform 2 is in the loading position, the inverted glass goblet is inserted into the positioning port 3. At this time, the inverted glass goblet is positioned in the positioning port 3, so that the extended line of the glass body axis is on the same straight line as the rotation axis of the mechanical gripper 1. Since the output direction line of the telescopic drive unit 4 is parallel to the axis of the positioning port 3, when the telescopic drive unit 4 is driven in the forward direction, the loading platform 2 lifts the glass goblet and moves it towards the position of the mechanical gripper 1 until the foot of the glass goblet on the loading platform 2 is in the gripping area of ​​the mechanical gripper 1. In the loading area, the material support platform 2 is in the unloading position. Then, the mechanical gripper 1 grips the stem of the glass goblet. At this time, the telescopic drive unit 4 performs reverse drive, which separates the glass goblet from the positioning port 3 until the material support platform 2 returns to the initial loading position, thus preparing for the next glass goblet to be inserted into the positioning port 3. Throughout the process, it can be ensured that the extended line of the glass body axis and the rotation axis of the mechanical gripper are on the same straight line, which helps to ensure that the rim of the glass has good cutting quality after laser cutting and greatly reduces the occurrence of rim tilting of the glass goblet.

[0035] In another embodiment of the present invention, the telescopic drive unit 4 includes a through-hole 4.1 penetrating the top of the material support platform 2. The axis of the through-hole 4.1 is perpendicular to the horizontal plane. A ball screw sleeve 4.2 is rotatably installed inside the through-hole 4.1. A lead screw 4.3 is adapted to pass through the ball screw sleeve 4.2. The axis of the lead screw 4.3 is parallel to the axis of the through-hole 4.1. A drive motor 4.4 is connected to the bottom end of the lead screw 4.3. Preferably, there are two through-holes 4.1. The drive motor 4.4 is a servo drive motor, and each servo motor can drive synchronously.

[0036] Furthermore, the material support platform 2 includes a platform 2.1 that is connected to the telescopic drive unit 4. A through-hole 4.1 is opened on the platform 2.1. A through-hole 2.2 is opened in the middle of the platform 2.1. The axis of the through-hole 2.2 is parallel to the axis of the through-hole 4.1. A rotating ring 2.3 is rotatably installed inside the through-hole 2.2. The axis of the rotating ring 2.3 coincides with the axis of the through-hole 2.2. The inner ring of the rotating ring 2.3 forms a positioning port 3. The rotating ring 2.3 is connected to the ball screw sleeve 4.2 through the transmission assembly 5. When the platform 2.1 moves, the rotating ring 2.3 can drive the glass goblet to rotate axially.

[0037] Furthermore, the transmission assembly 5 includes a first annular groove 5.1 formed on the inner wall of the through opening 2.2. The first annular groove 5.1 is rotatably engaged with the rotating ring 2.3. A circumferential groove 5.5 connected to the first annular groove 5.1 is formed on the inner side wall of the through opening 4.1. A first toothed ring 5.6 is rotatably adapted to be fixedly sleeved with the ball thread sleeve 4.2 in the circumferential groove 5.5. A second toothed ring 5.7 adapted to mesh with the first toothed ring 5.6 is fixed on the outer circumferential surface of the rotating ring 2.3.

[0038] Specifically, a second annular groove 5.2 is provided on the annular wall of the first annular groove 5.1. A protruding block 5.3 fixed to the rotating ring 2.3 is slidably fitted in the second annular groove 5.2. A blocking unit 5.4 located on the movement trajectory line of the protruding block 5.3 is installed in the second annular groove 5.2. When the protruding block 5.3 contacts the blocking unit 5.4, the rotating ring 2.3 is in a stop-rotation position.

[0039] In practical use, for example, when the material support platform 2 is in the initial loading position, after the inverted glass goblet is inserted into the positioning port 3 of the material support platform 2, the drive motor 4.4 drives the lead screw 4.3 to rotate in the forward direction. This causes the ball screw sleeve 4.2, which is helically connected to the lead screw 4.3, to drive the first toothed ring 5.6 to rotate in the forward direction within the circumferential groove 5.5. At this time, the material support platform 2 is still in the loading position in the vertical direction. Since the outer circumferential surface of the rotating ring 2.3 is fixed with a second toothed ring 5.7 that is adapted to mesh with the first toothed ring 5.6, and the rotation direction of the second toothed ring 5.7 is opposite to the rotation direction of the first toothed ring 5.6, the second toothed ring 5.7 also drives the rotating ring 2.3 to rotate in the same clockwise direction, causing the glass goblet on the rotating ring 2.3 to rotate axially. It should be noted that the clockwise rotation direction of the rotating ring 2.3 is opposite to the forward rotation direction of the first toothed ring 5.6.

[0040] During the clockwise rotation of the rotating ring 2.3, the protruding block 5.3, which is fixed to the side of the rotating ring 2.3, also slides forward along the annular line of the second annular groove 5.2. When the protruding block 5.3 slides to the position of the blocking unit 5.4, the protruding block 5.3 contacts the front of the blocking unit 5.4, thus the blocking unit 5.4 blocks the forward sliding of the protruding block 5.3. Consequently, the rotating ring 2.3 can no longer rotate clockwise and is in a stopped position. Therefore, the second toothed ring 5.7 can no longer rotate, which causes the first toothed ring 5.6, which meshes with the second toothed ring 5.7, to also be unable to continue rotating forward in the circumferential groove 5.5, and the ball screw sleeve 4.2 to also be unable to continue rotating forward in the through-hole 4.1.

[0041] As the drive motor 4.4 drives the lead screw 4.3 to continue rotating in the forward direction, the material support platform 2 moves vertically toward the direction of the mechanical gripper 1 until the material support platform 2 reaches the unloading position. At this time, the foot of the glass goblet on the material support platform 2 is in the gripping area of ​​the mechanical gripper 1.

[0042] Similarly, when the drive motor 4.4 drives the lead screw 4.3 to rotate in the opposite direction, the material support platform 2 returns from the unloading position to the loading position. The transmission principle is the same as that of the material support platform 2 moving from the loading position to the supporting position, but the direction of movement is opposite. For example, when the drive motor 4.4 drives the lead screw 4.3 to rotate in the opposite direction, the rotating ring 2.3 rotates counterclockwise. The protruding block 5.3, which is fixed to the side of the rotating ring 2.3, also slides in the opposite direction along the annular line of the second annular groove 5.2. As a result, the protruding block 5.3 moves away from the front of the blocking unit 5.4, and finally the protruding block 5.3 contacts the back of the blocking unit 5.4. Then the material support platform 2 moves from the unloading position to the loading position. Therefore, the material support platform 2 can reciprocate between the unloading position and the loading position. During the movement, it can provide driving force for the axial rotation of the glass goblet on the rotating ring 2.3.

[0043] In another embodiment of the present invention, an annular stepped groove 9 is provided on the inner ring surface of the top of the rotating ring 2.3. An inner liner ring 10 is adapted to be installed on the annular stepped groove 9. The inner ring diameter of the inner liner ring 10 is the same as the inner ring opening diameter of the rotating ring 2.3. An annular inclined portion 11 is provided on the inner side wall of the inner liner ring 10. The inclination of the annular inclined portion 11 is adapted to the inclination of the corresponding glass stem. A plurality of positioning holes 12 are provided on the bottom surface of the inner liner ring 10. A positioning protrusion 13 that can be adapted to be inserted into the positioning hole 12 is fixed on the groove wall of the annular stepped groove 9.

[0044] In practical use, the tilt angle of glass stems varies for different types and specifications. Based on the tilt angle of the glass stems of the actual specifications, the inner lining ring 10 of the corresponding annular beveled part 11 is selected. Then, the inner lining ring 10 is placed on the annular stepped groove 9, and the positioning hole 12 is matched with the positioning protrusion 13 to prevent the inner lining ring 10 from sliding relative to the annular stepped groove 9, thereby improving the compatibility of the positioning port 3 with the glass stems of different specifications.

[0045] In another embodiment of the present invention, a plurality of evenly distributed pin holes 6 are provided on the inner wall surface of the through-hole 2.2, for example, the number of pin holes 6 is 3. All pin holes 6 are located below the first annular groove 5.1. Each pin hole 6 is spirally inserted with a plug post 7. The extension line of the axis of the plug post 7 is perpendicular to the axis of the through-hole 2.2. Each plug post 7 is movably mounted with a universal ball 8 at its end. The center of the circumferential ring formed by the outer ends of each plug post 7 is located on the axis of the through-hole 2.2. That is to say, the end of the plug post 7 with the universal ball 8 forms a ring line with the center of the ring line on the axis of the through-hole 2.2.

[0046] In actual use, when the rotating ring 2.3 drives the glass goblet to rotate axially, the glass body of the rotating glass goblet is in rolling contact with the universal ball 8. It should be noted that the glass body part in rolling contact with the universal ball 8 is the recycled glass goblet waste part after subsequent cutting.

[0047] During the axial rotation of a glass goblet, under normal circumstances, the axis of the goblet's body is aligned with the axis of rotation. At this time, the rotating goblet's body is in rolling contact with the universal balls 8. However, if the goblet is tilted, the axis of the goblet's body and the axis of rotation are not completely aligned. Therefore, during rotation, the goblet's body cannot simultaneously contact all the universal balls 8, and the goblet's body is subjected to the force of the contacting universal balls 8, thus correcting the goblet's posture. Ultimately, the axis of the goblet's body and the axis of rotation are aligned, thus achieving a corrective effect on the goblet's body.

[0048] In another embodiment of the present invention, the blocking unit 5.4 includes a recessed groove 5.41 formed on the bottom surface of the second annular groove 5.2, and a stop post 5.42 is adapted to be inserted into the recessed groove 5.41. The length direction line of the stop post 5.42 is parallel to the length direction line of the lead screw 4.3, and the post body of the stop post 5.42 is located on the movement trajectory line of the protruding block 5.3.

[0049] Furthermore, a notch 5.43 is provided on one side of the stop post 5.42 to allow the protruding block 5.3 to pass through. A backstop baffle 5.45 is movably installed inside the notch 5.43. Specifically, the backstop baffle 5.45 includes a baffle body 5.451 that is movably hinged to the top surface of the notch 5.43. A limiting block 5.452 is provided on one side of the top of the baffle body 5.451 and is fixed to the top of the notch 5.43. The limiting block 5.452 can block the reverse deflection of the baffle body 5.451. Preferably, the baffle body... A torsion spring is installed between the interior of 5.451 and the notch 5.43. In its natural state, the baffle body 5.451 is in a state of blocking the notch 5.43. The top of the baffle post 5.42 extends movably from the top surface of the platform 2.1. The baffle post 5.42 and the platform 2.1 are connected by an elastic reset component 5.44. In its natural state, the elastic reset component 5.44 keeps the post 5.42 on the movement trajectory line of the protruding block 5.3. Preferably, the cross-sectional outline of the baffle post 5.42 is rectangular.

[0050] Specifically, the elastic reset assembly 5.44 includes a retaining ring plate 5.441 located above the platform 2.1 and fixedly sleeved with the retaining post 5.42. The retaining ring plate 5.441 and the platform 2.1 are connected and fixedly connected by a first spring 5.442, which is movably sleeved on the retaining post 5.42.

[0051] A base plate 14 is provided directly below the material support platform 2. The base plate 14 is fixed to the drive motor 4.4. A column 15 is fixed on the base plate 14. The number of columns 15 can be selected as multiple. The column 15 moves through the top of the material support platform 2 and guides the vertical movement of the material support platform 2. The axis of the column 15 is parallel to the axis of the lead screw 4.3. A horizontal stop bar 16 is fixed on the column body of the column 15. When the stop bar 5.42 moves vertically with the material support platform 2, the stop bar 5.42 can move along the length direction line of the stop bar 5.42. The horizontal stop bar 16 is located on the trajectory line of the length direction line of the stop bar 5.42.

[0052] In actual use, for example, when the material support platform 2 moves from the loading position to the unloading position, the stop post 5.42 moves closer to the horizontal stop bar 16. The column of the stop post 5.42 is located on the movement trajectory line of the protruding block 5.3. The protruding block 5.3 is in contact with the front of the stop post 5.42, and the stop post 5.42 blocks the protruding block 5.3.

[0053] As the material support platform 2 continues to move towards the unloading position, when the top of the stop post 5.42 is pressed against the bottom of the horizontal stop bar 16, the bottom end of the stop post 5.42 further inserts into the sinkhole 5.41. At this time, the first spring 5.442 undergoes elastic compression deformation between the retaining ring plate 5.441 and the platform 2.1. This causes the notch 5.43 to be positioned on the trajectory of the protruding block 5.3. As the screw 4.3 continues to rotate in the forward direction, the protruding block 5.3 can pass through the notch 5.43 and the stop post 5.42. At this time, the baffle body 5.451 of the anti-reverse baffle 5.45 is deflected in the forward direction under the squeezing action of the protruding block 5.3, so that the protruding block 5.3 moves from the front position of the stop post 5.42 to the back position of the stop post 5.42. When the protruding block 5.3 is in the back position of the stop post 5.42, the screw 4.3 immediately stops rotating in the forward direction, and the baffle body 5.451 also returns to the state of blocking the notch 5.43. At this time, the material support platform 2 also reaches the unloading position. During the process of the protruding block 5.3 passing through the notch 5.43, the material support platform 2 is in a vertical and stopped state.

[0054] When the material support platform 2 is about to move toward the loading position, the lead screw 4.3 rotates in the opposite direction. The protruding block 5.3, fixed to the side of the rotating ring 2.3, also slides in the opposite direction along the annular line of the second annular groove 5.2. When the sliding protruding block 5.3 passes through the notch 5.43, it is blocked by the anti-reverse baffle 5.45, preventing it from passing through. In other words, the protruding block 5.3 cannot pass through the notch 5.43 from the back of the stop post 5.42 to the front. The anti-reverse baffle 5.45 then blocks the protruding block 5.3, causing the lead screw 4.3 to rotate in the opposite direction. At this point, the material support platform 2 can immediately move toward the loading position without waiting for the rotating ring 2.3 to rotate counterclockwise, saving the return time of the material support platform 2.

[0055] When the material support platform 2 reaches the loading position, the horizontal stop bar 16 has already separated from the stop bar 5.42. At this time, under the elastic restoring force of the first spring 5.442, the column of the stop bar 5.42 is back on the movement trajectory line of the protrusion block 5.3, so it can block the forward sliding of the protrusion block 5.3 again.

[0056] In short, the application ensures that the extended axis of the glass stem is aligned with the rotation axis of the mechanical gripper, which helps ensure good cutting quality at the rim after laser cutting. Furthermore, as the support platform 2 moves the glass stem close to the mechanical gripper, it allows for further inspection and correction. Moreover, when the support platform 2 returns to the loading position, it can immediately move downwards, saving time and improving work efficiency.

[0057] In another embodiment of the present invention, the elastic reset component 5.44 includes a second spring 5.443 located in the sinking groove 5.41. The bottom end of the second spring 5.443 is fixed to the bottom of the sinking groove 5.41, and the top end of the second spring 5.443 is fixed to the bottom end of the stop post 5.42. When the top end of the stop post 5.42 is pressed against the horizontal stop bar 16, the stop post 5.42 penetrates further into the sinking groove 5.41. At this time, the second spring 5.443 is in an elastic compression deformation state. When the material support platform 2 reaches the loading position, the horizontal stop bar 16 has already separated from the stop post 5.42. At this time, under the action of the elastic restoring force of the second spring 5.443, the column of the stop post 5.42 is back on the movement trajectory line of the protrusion block 5.3.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
