Description

Technical Field

[0001] The utility model relates to the field of glass production, in particular to a clamping and transporting device with good adaptability for processing ultra-thin-wall glassware. Background Art

[0002] During the production process of glassware, sometimes different production lines and production stations are involved. Therefore, when transferring between different production lines and production stations, transfer equipment is needed. One of the main functions of the transfer equipment is to clamp and fix the glassware. Because glass is a fragile item, especially for ultra-thin-walled glass, the wall thickness is thinner and the pressure it can withstand is smaller, so it is more easily damaged.

[0003] In actual use, since the maximum pressure that the glass can withstand is known, the transfer device needs to apply sufficient pressure to the glassware to ensure smooth clamping. At the same time, it is also necessary to ensure that the pressure applied by the transfer device is less than or equal to the maximum pressure that the glass can withstand. Utility Model Content

[0004] In order to solve the technical problem that thin-walled glassware is easily broken when clamped, the utility model provides a clamping and transferring device for processing ultra-thin-walled glassware with good adaptability.

[0005] The utility model adopts the following technical scheme to realize: a gripping and transferring device for processing ultra-thin-wall glassware with good adaptability, comprising a conveyor belt, a base is arranged on one side of the conveyor belt, and the base is provided with:

[0006] A rotating disk, the rotating disk is rotatably mounted on the base;

[0007] A slide plate, the slide plate is movably mounted on the rotating disk, and the slide plate can reciprocate on the rotating disk;

[0008] A mounting frame, the mounting frame being fixedly connected to one side of the slide plate;

[0009] A rotating clamping plate, the rotating clamping plate is movably mounted on the mounting frame, and a clamping claw is mounted on one end of the rotating clamping plate;

[0010] A clamping spring is provided between the mounting frame and the rotating clamping plate;

[0011] A limiting mechanism is arranged on the mounting frame, and is used to limit the rotation angle of the rotating clamping plate.

[0012] Through the above technical solution, when the glassware reaches the specified position via the conveyor belt, the slide is controlled to move back and forth in a straight line, so as to adjust the distance between the two mounting frames until the rotating clamp cooperates with the clamping claw to clamp the glassware. Since the clamping spring is stretched during the clamping process, the pressure of the clamping claw on the glassware comes from the stretched spring. Therefore, when the stretched length of the spring is fixed, the pressure on the product is also fixed, so there is no need to worry about crushing the glassware.

[0013] As a further improvement of the above solution, a rotating shaft is fixedly connected to the bottom of the rotating disk, one end of the rotating shaft is connected to a motor, and the motor is fixedly installed on the bottom of the base.

[0014] As a further improvement of the above solution, the rotating disk is provided with a driving mechanism, and the driving mechanism is used to drive the slide plate to move back and forth, and the driving mechanism includes:

[0015] A bidirectional screw rod, the bidirectional screw rod is rotatably mounted on the rotating disk, one end of the bidirectional screw rod is connected to a motor, and a movable sleeve on the bidirectional screw rod is provided with two slide plates;

[0016] A guide rod is fixedly mounted on the rotating disk, a corresponding guide hole is opened on the slide plate, and the guide rod passes through the slide plate.

[0017] Through the above technical solution, two ends of the bidirectional lead screw are respectively provided with two sections of threads in opposite directions. Therefore, when the motor drives it to rotate forward and reverse, the two slides can be driven to move back and forth in a straight line in cooperation with the guiding and limiting function of the guide rod.

[0018] As a further improvement of the above solution, a limiting sleeve is sleeved on the guide rod, and a fastening screw is connected to the limiting sleeve.

[0019] Through the above technical solution, when the fastening screw is tightened, the limit sleeve is fixed on the guide rod, and when the fastening screw is loosened, the limit sleeve can slide along the guide rod. Therefore, different limiting effects can be achieved on the slide plate by changing the position of the limit sleeve.

[0020] As a further improvement of the above solution, the mounting frame is fixedly connected to a first fixed shaft, and the rotating clamp is sleeved on the first fixed shaft.

[0021] As a further improvement of the above solution, the limiting mechanism includes:

[0022] A fixed limit block, the fixed limit block is fixedly mounted on the inner side of the mounting frame;

[0023] A movable limiting rod, wherein a through limiting hole is provided on the mounting frame, and the movable limiting rod is inserted into the limiting hole;

[0024] A control paddle, the control paddle is rotatably mounted on the mounting frame, and one end of the movable limiting rod is fixedly connected to the control paddle;

[0025] A fastening nut is threadedly mounted on one end of the movable limiting rod.

[0026] Through the above technical solution, because when the mounting frame is fixed, the movable limit rod rotates around the first fixed axis, and the rotatable angle of the rotating clamp is limited by the fixed limit block and the movable limit block, when the rotating clamp rotates, the length of the clamping spring will be changed, and the rotation angle of the rotating clamp is limited. Therefore, the changed length of the clamping spring is limited, and the position of the movable limit rod is adjustable.

[0027] As a further improvement of the above solution, a baffle is provided at one end of the conveyor belt.

[0028] Through the above technical solution, the baffle is used to stop the glassware at one end of the conveyor belt, making it easier for the gripper to grab the glassware.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] When the utility model clamps the glassware by the clamping claw, the clamping plate and the mounting frame are rotated to stretch the clamping spring. Since the clamping force of the clamping claw on the glassware mainly comes from the stretched clamping spring, the stretched length of the clamping spring can be controlled to remain unchanged, so that the clamping force of the clamping claw remains almost unchanged, especially when clamping thin-walled glass (the pressure that the glassware can withstand is known), it can prevent the glassware from being damaged due to excessive pressure.

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0039] Please combine Figure 1 - Figure 6 The present embodiment is a gripping and transferring device for processing ultra-thin-walled glassware with good adaptability, including a conveyor belt 1, which is used to transfer glassware. A baffle 15 is also installed at one end of the conveyor belt 1, and the baffle 15 is used to position and block the glassware to facilitate the subsequent gripping mechanism to grip it. This is the prior art.

[0040] When the glassware needs to be transferred to the next production line or for other operations after passing through the conveyor belt 1, the clamping and transferring device described in this embodiment is needed. Specifically, a base 2 is first provided on one side of the conveyor belt 1, a motor is installed at the bottom of the base 2, and a rotating disk 3 is rotatably installed on the base 2. The rotating disk 3 is connected to the motor, and the motor can drive the rotating disk 3 to rotate.

[0041] In addition, a mounting groove (not marked in the figure) is provided on the rotating disk 3, and two slide plates 4 and a driving mechanism 5 are arranged in the mounting groove, wherein the driving mechanism 5 can drive the two slide plates 4 to move back and forth in a straight line in the mounting groove, specifically:

[0042] The driving mechanism 5 includes a motor, a bidirectional screw rod 51 and a guide rod 52. First, the bidirectional screw rod 51 is provided with two sections of threads in opposite directions, and one end is connected to the motor, and the other end is fixedly connected to the rotating disk 3. Two guide rods 52 are provided, and the two guide rods 52 are fixedly installed in the mounting groove of the rotating disk 3. At the same time, the two slides 4 are provided with corresponding through holes, that is, the bidirectional screw rod 51 and the guide rod 52 are integrally penetrated through the slide 4. Therefore, when the motor and the bidirectional screw rod 51 are controlled to rotate, the two slides 4 can be driven to move relative to or toward each other, and the distance between the two slides 4 can be adjusted.

[0043] In addition, a limiting sleeve 6 is provided on the guide rod 52, wherein both ends of the limiting sleeve 6 are provided with through holes, and the limiting sleeve 6 is integrally sleeved on the two guide rods 52, and a fastening screw 7 is connected to the limiting sleeve 6, so when the fastening screw 7 is tightened, the limiting sleeve 6 is fixed on the guide rod 52, and when the fastening screw 7 is loosened, the limiting sleeve 6 can slide along the guide rod 52, and two limiting sleeves 6 are provided, so different limiting effects can be played on the slide plate 4 by changing the position of the limiting sleeve 6.

[0044] A mounting frame 8 is fixedly connected to the slide plate 4 , and a first fixed shaft 9 is fixedly connected inside the mounting frame 8 . A rotating clamping plate 10 is provided inside the mounting frame 8 and outside the first fixed shaft 9 , that is, the rotating clamping plate 10 can rotate around the first fixed shaft 9 .

[0045] One end of the rotating clamp 10 extends out of the mounting frame 8 and is connected to a clamp 11 by a screw. The clamp 11 is used to fix the glassware, so a V-shape is provided on the inner side of the clamp 11 to facilitate fixing the glassware. In actual use, a soft sponge pad (not marked in the figure) can also be laid on the inner side to further protect the glass.

[0046] In addition, a clamping spring 12 is connected between the rotating clamping plate 10 and the mounting frame 8, that is, one end of the clamping spring 12 is fixed to the mounting frame 8, and the other end is fixed to the rotating clamping plate 10. Moreover, as described above, the rotating clamping plate 10 can rotate around the first fixed axis 9. At this time, after the clamping spring 12 is installed, when the rotating clamping plate 10 rotates again, the clamping spring 12 will be stretched.

[0047] In summary, with the cooperation of the driving mechanism 5, the slide plate 4 can be driven to move back and forth along the direction of the guide rod 52 to adjust the distance between the two slide plates 4. When the distance between the two slide plates 4 gradually decreases, the two mounting frames 8 approach each other, driving the two rotating clamps 10 and the two clamping claws 11 to approach each other. When gradually contacting the glassware, the clamping claw 11 with the V-shaped groove first clamps the glassware.

[0048] If the two mounting frames 8 and the two rotating clamping plates 10 continue to approach, the rotating clamping plate 10 will rotate around the first fixed axis 9, and the clamping spring 12 will be stretched. Since the stretched clamping spring 12 has a tendency to return to the initial state, the restoring force of the stretched clamping spring 12 acts on the clamping jaws 11 through the rotating clamping plate 10, so that the clamping jaws 11 only clamp the glassware.

[0049] Therefore, the clamping force of the clamping jaw 11 for clamping the glassware mainly comes from the stretched clamping spring 12. Within a certain range, if the stretched length of the clamping spring 12 is kept constant, the clamping force of the clamping jaw 11 will also remain almost constant. By controlling the size of the clamping force, it can be kept within an appropriate range to avoid damage to the glassware.

[0050] Further, in the above description, when the rotating clamping plate 10 rotates around the first fixed axis 9, the clamping spring 12 is stretched. In order to further control the rotation angle of the rotating clamping plate 10, a limiting mechanism 13 is also provided on the mounting frame 8. Specifically, the limiting mechanism 13 includes a fixed limiting block 131 and a movable limiting rod 132 with adjustable position. First, the fixed limiting block 131 is fixedly installed on the inner side of the mounting frame 8.

[0051] In order to install the movable limit rod 132, a through arc-shaped limit hole 14 is opened on the mounting frame 8, and the movable limit rod 132 is inserted in the limit hole 14, and a control paddle 133 is rotatably connected to the mounting frame 8. At the same time, one end of the movable limit rod 132 is fixedly connected to the control paddle 133, and a section of thread is opened at the other end of the movable limit rod 132, and a fastening nut 134 is connected. Therefore, when the fastening nut 134 is not locked, rotating the control paddle 133 can drive the movable limit rod 132 to move along the arc-shaped limit hole 14, thereby adjusting its position relationship with the rotating clamp 10. When the fastening nut 134 is tightened, that is, the fastening nut 134 is tightly fitted to one side of the mounting frame 8, the movable limit rod 132 cannot move.

[0052] Therefore, the fixed limiting block 131 and the movable limiting rod 132 limit the rotating clamping plate 10 from two directions respectively, and the area between the fixed limiting block 131 and the movable limiting rod 132 is the range in which the rotating clamping plate 10 can rotate freely.

[0053] The implementation process and principle of a gripping and transferring device for processing ultra-thin-walled glassware with good adaptability in the embodiment of the present application are as follows:

[0054] When the glass easily reaches the baffle 15 at one end of the conveyor belt 1, the slide plate 4 is driven to move by the driving mechanism 5, thereby driving the two sets of mounting frames 8 to approach each other, so that the rotating clamping plate 10 and the clamping claw 11 gradually approach the glassware until the clamping claw 11 fits the glassware;

[0055] At this time, if the two sets of mounting frames 8 continue to approach each other, the clamping jaws 11 clamp the glassware, and at the same time, the rotating clamping plate 10 rotates around the first fixed axis 9, and the clamping spring 12 is stretched. Since the clamping force of the clamping jaws 11 on the glassware mainly comes from the stretched clamping spring 12, the reason why the clamping spring 12 is stretched is the rotation of the rotating clamping plate 10, and the limiting mechanism 13 can control the maximum rotation angle of the rotating clamping plate 10, so the extension length of the clamping spring 12 can be controlled;

[0056] When the elongated length of the clamping spring 12 is controlled to remain unchanged, the clamping force of the clamping jaw 11 is also almost unchanged. Therefore, it can be said that the clamping force can be ultimately controlled to remain within a suitable range through the limiting mechanism 13 to avoid damage to the glassware, especially for thin-walled glass (the pressure that the glassware can withstand is known), which can prevent the glassware from being damaged due to excessive pressure.

[0057] After the clamping jaws 11 clamp the glassware, the position of the glassware is changed by controlling the rotation of the rotating disk 3.

[0058] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
