Description

Technical Field

[0001] This utility model belongs to the field of glass tube processing technology, and specifically relates to a glass tube drilling and positioning device. Background Technology

[0002] During the glass tube processing, the glass tubes are usually detachably placed in the grooves on the surface of the conveyor belt and transported sequentially to each processing station along the preset process path. When the glass tubes are transported to the drilling station, the positioning device moves multiple glass tubes on the conveyor belt to the top of the drilling equipment at the same time. Then the drilling equipment performs drilling operations on the glass tubes by outputting needle-shaped flames.

[0003] However, in actual operation, it was found that some glass tubes may be damaged for various reasons before reaching the drilling process and fall off the conveyor belt. Since the positioning device usually moves multiple glass tubes to the drilling position at the same time, when there are missing or fallen glass tubes, the needle-shaped flame output by the drilling equipment will not be able to accurately act on the target glass tube, resulting in the waste of flame energy during the glass tube drilling process.

[0026] This utility model provides a glass tube drilling and positioning device, including an induction switch and a first positioning mechanism 100.

[0027] The following combination Figures 1-5 The structure and shape of the glass tube drilling and positioning device are described in detail:

[0028] The first positioning mechanism 100 includes a transverse structure 110 and a positioning tray 121. A sensor switch is configured to control the conveyor belt to transport the glass tube above the positioning tray 121 when a glass tube is detected in a groove on the surface of the conveyor belt. The positioning tray 121 is configured to move vertically to lift and release the glass tube above it from the groove of the conveyor belt during the upward movement. A positioning slot is provided on the side of the positioning tray 121 facing the glass tube, which is used to clamp and position the glass tube when it is lifted. The transverse structure 110 is configured to drive the positioning tray 121 to move along the extension direction of the conveyor belt, thereby moving the glass tube clamped by the positioning tray 121 to the drilling station.

[0029] In this embodiment, after the inductive switch detects the presence of a glass tube in the groove on the surface of the conveyor belt, it controls the conveyor belt to transport the glass tube to the top of the positioning tray. Then, the positioning tray 121 moves vertically upward to lift the glass tube above it out of the groove of the conveyor belt. During this process, the positioning groove on the positioning tray 121 clamps and positions the glass tube. Then, the transverse moving structure 110 drives the positioning tray 121 to move along the extension direction of the conveyor belt to move the glass tube clamped by the positioning tray 121 to the drilling station.

[0030] In order for the inductive switch to control the conveyor belt to transport the glass tube above the positioning tray 121:

[0031] The glass tube drilling and positioning device also includes a controller; when the conveyor belt drives the glass tube past the detection end of the sensing element, the sensing element is triggered and transmits a trigger signal to the controller. The controller determines that the glass tube is in the groove on the conveyor belt according to the trigger signal, and controls the conveyor belt to move the groove containing the glass tube to the top of the positioning tray 121. The type of sensing switch includes, but is not limited to, proximity switches.

[0032] To drive the positioning plate 121 to move vertically upward:

[0033] like Figure 2 and Figure 4 As shown, the first positioning mechanism 100 also includes a clamping structure 120 and a lifting structure 130; the clamping structure 120 includes a positioning tray 121, a bearing frame 122 and mounting bolts 123; the positioning tray 121 is installed in the bearing frame 122 by the mounting bolts 123, and its surface is provided with a positioning guide hole extending in the vertical direction; the mounting bolts 123 are inserted into the positioning guide hole and can slide along the length direction of the positioning guide hole; the lifting structure 130 is configured to drive the positioning tray 121 to move vertically upward.

[0034] In this embodiment, when the positioning plate 121 causes the glass tube to detach from the conveyor belt, the lifting structure 130 causes the positioning plate 121 to move upward. During this process, the positioning guide hole moves along the mounting bolt 123, thereby restricting the movement of the positioning plate 121 except in the vertical direction.

[0035] When the positioning plate 121 moves the glass tube back to the conveyor belt, the lifting structure 130 moves the positioning plate 121 downward. During this process, the positioning guide hole moves along the mounting bolt 123, thereby restricting the movement of the positioning plate 121 except in the vertical direction.

[0036] In order to enable the lifting structure 130 to drive the positioning plate 121 to move:

[0037] like Figures 4-5As shown, the lifting structure 130 includes a lifting frame 131, a drive motor 132, a lifting rail 133, a lifting screw 134, and a lifting push plate 135. The lifting rail 133 is connected to the support frame 122 and is slidably inserted into the lifting push plate 135. The lifting screw 134 is inserted into the lifting push plate 135 and is threadedly connected to the lifting push plate 135. The lifting push plate 135 is located below the positioning support plate 121. The drive motor 132 is mounted on the lifting frame 131, and its rotation shaft is connected to the lifting screw 134. It is used to drive the lifting push plate 135 to move vertically, so that the lifting push plate 135 is in contact with the positioning support plate 121 and drives the positioning support plate 121 to move vertically upward.

[0038] In this embodiment, when it is necessary to move the positioning plate 121 vertically upward, the drive motor 132 drives the lifting screw 134 to rotate around its own axis. The rotating lifting screw 134, with the cooperation of the thread, drives the lifting push plate 135 to move upward along the lifting circular rail 133. The upward-moving lifting push plate 135 is in contact with the positioning plate 121 and drives the positioning plate 121 to move vertically upward.

[0039] When it is necessary to move the positioning plate 121 vertically downward, the drive motor 132 drives the lifting screw 134 to rotate around its own axis. The rotating lifting screw 134, with the help of the thread, drives the lifting push plate 135 to move downward along the lifting circular rail 133. During this process, the positioning plate 121 moves downward with the lifting push plate 135 under the action of gravity.

[0040] To drive the positioning plate 121 to move the glass tube to the drilling station:

[0041] like Figure 3 As shown, the transverse structure 110 includes a transverse support 111 and a transverse push cylinder 112; the transverse push cylinder 112 is installed on the transverse support 111 and its telescopic end is connected to the bearing frame 122, which is used to drive the clamping structure 120 and the lifting structure 130 to move along the extension direction of the conveyor belt.

[0042] In this embodiment, the transverse push cylinder 112 drives the bearing frame 122 to move along the extension direction of the conveyor belt. The bearing frame 122 drives the positioning plate 121 to move through the mounting bolts 123. The positioning plate 121 drives the glass tube to the drilling station.

[0043] To reduce the stress on the transverse push cylinder 112 in the vertical direction:

[0044] like Figure 3 As shown, the transverse structure 110 also includes a support guide rod 113 and a support base 114; one end of the support guide rod 113 is connected to the transverse support 111, and the other end is inserted into the support base 114 and slidably connected to the support base 114; the support base 114 is connected to the load-bearing frame 122.

[0045] In this embodiment, the transverse push cylinder 112 drives the support seat 114 to move along the support guide rod 113 through the bearing frame 122. During this process, the stress generated by the clamping structure 120 and the lifting structure 130 in the vertical direction is transmitted to the support guide rod 113 in real time through the support seat 114. The stress on the support guide rod 113 is transmitted to the installation position through the transverse support 111.

[0046] To synchronously drive multiple glass tubes to the drilling station:

[0047] like Figure 2 , Figure 4 and Figure 5 As shown, the clamping structure 120 includes multiple positioning trays 121 and multiple limiting components 124; the starting area where the lateral movement structure 110 drives the positioning trays 121 to move towards the drilling station is set as a buffer zone; the inductive switch controls the conveyor belt to sequentially transport the glass tubes in multiple slots to the top of the multiple positioning trays 121; the first positioning mechanism 100 also includes an adjusting structure 140; the adjusting structure 140 is configured to drive the lifting structure 130 to move along the extension direction of the conveyor belt, so that the lifting structure 130 moves to the bottom of the corresponding positioning tray 121 and drives the positioning tray 121 to move vertically upward; the multiple limiting components 124 are all installed on the support frame 122 and are respectively located on one side of the multiple positioning trays 121, for locking the positioning trays 121 with the support frame 122 when they rise to the set position, so that the glass tubes are temporarily stored in the buffer zone.

[0048] In this embodiment, the adjustment structure 140 drives the lifting structure 130 to move in the opposite direction of the conveyor belt, so that the lifting push plate 135 in the lifting structure 130 moves to the bottom of the positioning tray 121. After the conveyor belt drives the glass tube to move above the positioning tray 121, the positioning tray 121 moves vertically upward so that the glass tube is disengaged from the conveyor belt and clamped and positioned. Then the limiting component 124 locks the positioning tray 121 to the bearing frame 122. The above steps are repeated until multiple positioning trays 121 drive a set number of glass tubes to converge in the buffer zone. Then the transverse moving structure 110 drives the glass tubes in the buffer zone to the drilling station through the clamping structure 120.

[0049] The type of the aforementioned limiting component 124 includes, but is not limited to, a push-pull electromagnet. When the type of the limiting component 124 is a push-pull electromagnet, a limiting hole is provided on the lifting push plate 135. After the positioning plate 121 moves the glass tube to a set height, the telescopic end of the push-pull electromagnet is inserted into the limiting hole so that the lifting push plate 135 is fixed to the bearing frame 122. The aforementioned limiting hole is a strip-shaped hole, and the length direction of the strip-shaped hole is the same as the length direction of the lifting push plate 135. After the telescopic end of the push-pull electromagnet is inserted into the limiting hole, the lifting push plate 135 moves the positioning plate 121 downward so that one end of the limiting hole abuts against the telescopic end of the push-pull electromagnet, thereby reducing the requirements for the movement accuracy of the lifting push plate 135.

[0050] In order for the adjustment structure 140 to drive the lifting structure 130 to move along the extension direction of the conveyor belt:

[0051] like Figure 5 As shown, the adjustment structure 140 includes an adjustment screw 141 and an adjustment motor 142; the adjustment motor 142 is mounted on the support frame 122, and its rotation shaft is connected to the adjustment screw 141; one end of the lifting frame 131 is fitted against the inner wall of the support frame 122, and the other end is threaded onto the adjustment screw 141.

[0052] In this embodiment, the adjusting motor 142 drives the adjusting screw 141 to rotate along its own axis. The rotating adjusting screw 141, with the engagement of the thread, drives the lifting frame 131 to move along the length direction of the bearing frame 122, thereby driving the lifting structure 130 to move along the extension direction of the conveyor belt. During the above process, the lifting frame 131 is in contact with the inner wall of the bearing frame 122 to limit the rotational movement of the lifting frame 131.

[0053] To reduce friction between the lifting frame 131 and the load-bearing frame 122:

[0054] like Figure 4 As shown, the lifting structure 130 also includes a guide pin 136; the mating surfaces of the support frame 122 and the lifting frame 131 are provided with offset guide holes extending along the conveyor belt extension direction; one end of the guide pin 136 is connected to the support frame 122, and the other end is inserted into the offset guide hole, and can slide along the length direction of the offset guide hole.

[0055] In this embodiment, the lifting frame 131 drives the guide pin 136 to slide along the length direction of the offset guide hole, so that the contact point between the lifting frame 131 and the bearing frame 122 is supported in the vertical direction, thereby reducing the friction between the lifting frame 131 and the bearing frame 122.

[0056] To improve the efficiency of drilling holes in glass tubes:

[0057] like Figure 1As shown, it also includes a second positioning mechanism 200; the components of the first positioning mechanism 100 and the second positioning mechanism 200 and their interrelationships are the same; when the glass tube on the first positioning mechanism 100 is being drilled, the second positioning mechanism 200 simultaneously drives the glass tube to detach from the conveyor belt and completes clamping and positioning; conversely, when the glass tube on the second positioning mechanism 200 is being drilled, the first positioning mechanism 100 simultaneously drives the glass tube to detach from the conveyor belt and completes clamping and positioning.

[0058] In this embodiment, when the glass tube on the first positioning mechanism 100 is being drilled, the second positioning mechanism 200 simultaneously drives the next batch of glass tubes to detach from the conveyor belt and completes clamping and positioning; conversely, when the glass tube on the second positioning mechanism 200 is being drilled, the first positioning mechanism 100 simultaneously drives the glass tube to detach from the conveyor belt and completes clamping and positioning. By alternating the use of the first positioning mechanism 100 and the second positioning mechanism 200, the positioning time of the glass tube is reduced, thereby improving the drilling efficiency of the glass tube.

[0059] To improve stability during the glass tube drilling process:

[0060] like Figure 1 As shown, it includes two first positioning mechanisms 100 and two second positioning mechanisms 200; the two first positioning mechanisms 100 are respectively arranged at both ends of the glass tube; the two second positioning mechanisms 200 are respectively arranged at both ends of the glass tube.

[0061] In this embodiment, two first positioning mechanisms 100 or two second positioning mechanisms 200 are used simultaneously to drive the glass tube to move vertically at both ends, so that both ends of the glass tube that are separated from the conveyor belt are supported, thereby improving the stability of the glass tube during the drilling process.

[0062] Regarding how to reset the glass tube to the conveyor belt:

[0063] In this embodiment, the transverse structure 110 moves the glass tube to the top of the groove on the conveyor belt via the clamping structure 120. Then, the drive motor 132 drives the lifting screw 134 to rotate, so that the lifting push plate 135 moves along the lifting circular rail 133. After the lifting push plate 135 is in contact with the positioning plate 121, the limiting component 124 separates the positioning plate 121 from the bearing frame 122. Then, the lifting push plate 135 moves the glass tube vertically downward via the positioning plate 121, so that the glass tube is inserted into the groove on the conveyor belt.

[0064] The first embodiment of the transverse moving structure 110 moving the glass tube via the clamping structure 120 is as follows:

[0065] In this embodiment, after the glass tube is punched, the transverse structure 110 moves the glass tube to the gap between adjacent needle flames on the punching station through the clamping structure 120. Then, the clamping structure 120 moves the glass tube back to the set groove of the conveyor belt. During this process, the needle flame continuously heats the punched part of the glass tube, thereby slowing down the rate at which the temperature of the punched part of the glass tube decreases, thus avoiding sudden cooling damage to the punched part of the glass tube.

[0066] The second embodiment of the transverse moving structure 110 moving the glass tube via the clamping structure 120 is as follows:

[0067] In this embodiment, after the glass tube is punched, the transverse structure 110 drives the glass tube to move along the conveying direction of the conveyor belt through the clamping structure 120, so that the glass tube is removed from the punching station. Then, the clamping structure 120 drives the glass tube to return to the set groove of the conveyor belt. Then, the transverse structure 110 drives the clamping structure 120 to move to the buffer zone. During this process, the first positioning mechanism 100 or the second positioning mechanism 200 drives the next batch of glass tubes to move to the punching station.

[0069] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent in such process, method, article, or apparatus / device.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments.
