Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically a glass plate clamp. Background Technology

[0002] During the production and processing of glass sheets, large glass sheets often need to be cut into smaller pieces, and then the smaller pieces are moved to a designated location by a hoisting mechanism to facilitate subsequent secondary processing.

[0003] In related technologies, clamps are generally used to lift glass plates. However, since glass plates are relatively smooth, existing clamps can only lift a single glass plate at a time, resulting in low carrying efficiency. Moreover, existing lifting clamps can only hold conventional rectangular glass plates and cannot stably hold glass plates of other shapes, such as round glass plates. When clamping, round glass plates are prone to slipping off the clamp. Therefore, a glass plate clamp is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide a glass plate clamp to solve the problems of low lifting efficiency and inability to clamp glass plates of various shapes mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glass plate clamp, including a worktable, wherein at least one set of rotating lifting mechanisms and a mechanical arm that slides up and down along the lifting mechanisms are provided on the worktable, and a clamping mechanism is provided on the mechanical arm.

[0006] As a further preferred embodiment of this technical solution: a rotating wheel is provided on the workbench, and the lifting mechanism is located on the wheel.

[0007] As a further preferred embodiment of this technical solution: the lifting mechanism includes a support block, a sliding rod, a lead screw, and a slider. The support block is located on the wheel, the sliding rod and the lead screw are located on the support block, the slider is slidably connected to the sliding rod, and the robotic arm is located on the slider.

[0008] As a further preferred embodiment of this technical solution: the robotic arm is provided with a rotating connecting column, and the connecting column is provided with a clamping mechanism.

[0009] As a further preferred embodiment of this technical solution: the clamping mechanism includes a crossbar and a clamping plate, a groove is formed at the bottom of the crossbar, and a sliding clamping plate is provided in the groove of the crossbar.

[0010] As a further preferred embodiment of this technical solution: the inner side of the clamping plate is slotted, and a rotating bearing plate is provided in the slot of the clamping plate. When the bearing plate is placed in the slot of the clamping plate or when it is supporting a glass plate, the bearing plate is perpendicular to the clamping plate.

[0011] As a further preferred embodiment of this technical solution: the clamping mechanism consists of at least two sets, with each pair of clamping mechanisms symmetrically arranged on both sides of the connecting column.

[0012] As a further preferred embodiment of this technical solution, the inner side of the clamping plate is provided with a suction cup.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a rotating lifting mechanism to drive the robotic arm and its clamping mechanism to descend and clamp the glass plate. The lifting mechanism is rotated again to move the glass plate to the designated area. At this time, another set of robotic arms and their clamping mechanisms continue to clamp the glass plate, which improves the speed of glass plate clamping and hoisting and reduces labor costs.

[0015] 2. By setting up a clamping mechanism, this utility model can adapt to clamping glass plates of different sizes. It can clamp multiple glass plates regardless of whether the glass plates are placed vertically or horizontally. Even when the shape of the glass plate is irregular, the clamping mechanism on the connecting column can be rotated to adapt to the placement position and shape of the glass plate, thereby further improving work efficiency.

[0016] 3. This utility model has suction cups on the inner side of the clamping plate, which can lift and clamp multiple glass plates or a single large glass plate. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1

[0024] Please see Figures 1-2 This utility model provides a technical solution: a glass plate clamp, including a worktable 1, a wheel 11 connected to the worktable 1, and a lifting mechanism provided on the wheel 11. In this embodiment, the worktable 1 is a circular boss structure, and a gear motor is provided on one side of the wheel 11. A belt is sleeved on the output shaft of the gear motor and the wheel 11. The rotation of the gear motor drives the wheel 11 to rotate, and the lifting mechanism rotates accordingly. The distance between the gear motor and the wheel 11 is not limited, as long as it does not interfere with the rotation of the lifting mechanism. The transmission through the output shaft of the gear motor and the belt sleeved on the wheel 11 is only one way of rotating the lifting mechanism, and does not mean that the lifting mechanism provided in this embodiment can only rotate in the above way. Other mechanisms that can make the lifting mechanism rotate can also be applied to the glass plate clamp of this utility model.

[0025] like Figures 1-2 As shown, the lifting mechanism includes a support block 21, a sliding rod 22, a lead screw 23, and a slider 24. The support block 21 is located on the wheel 11, and the sliding rod 22 and the lead screw 23 are disposed on the support block 21. The lead screw 23 is driven to rotate spirally by a motor, and the slider 24 is slidably connected to the sliding rod 22. In this embodiment, there are two sliding rods 22 in each lifting mechanism, which are located on both sides of the lead screw 23, so that the slider 24 can slide smoothly on the sliding rod 22.

[0026] like Figures 1-2 As shown, a robotic arm 3 is fixedly connected to the slider 24, for example by bolts.

[0027] like Figures 1-4 As shown, a connecting column 31 is connected to the robotic arm 3. Specifically, the connecting column 31 rotates on the robotic arm 3. The rotation method of the connecting column 31 can be the same as that of the wheel 11, and it can be rotated by connecting a belt to the output shaft of the gear motor and the connecting column 31.

[0028] like Figures 1-4 As shown, a clamping mechanism is provided on the connecting column 31. Specifically, the clamping mechanism includes a crossbar 41 and a clamping plate 42. A groove is formed at the bottom of the crossbar 41, and the clamping plate 42 is slidably connected to the groove of the crossbar 41. In this embodiment, there are at least two sets of clamping mechanisms, and the two sets of clamping mechanisms are symmetrically arranged on both sides of the connecting column 31 to ensure stable clamping of the glass plate. Since the clamping plate 42 can slide on the crossbar 41, it can adapt to glass plates of different sizes. During use, the distance between the two clamping plates 42 can be adjusted according to the size of the glass plate.

[0029] Considering production needs, when the glass plate is circular or other irregular in shape, two sets of clamping mechanisms are insufficient to stably hold the glass plate, posing a risk of the glass plate slipping off the clamp. Therefore, the clamping mechanism can also be four sets, located around the connecting column 31. Since the connecting column 31 is rotatable, when the glass plate is not placed in a standard position or has an irregular shape, the clamping mechanism on the connecting column 31 can be rotated to adapt to the placement position and shape of the glass plate, thereby reducing manpower and material resources. Furthermore, the placement position of the glass plate can be adjusted according to actual usage requirements.

[0030] Considering that the glass plate will slip off between the clamping plates 42 when it is held by clamping plates 42 alone, a support plate 43 is provided on the inner bottom of the clamping plates 42. The support plate 43 is used to support the glass plate, and can support it whether the glass plate is placed horizontally or vertically.

[0031] The working principle of this embodiment is as follows:

[0032] In this embodiment, the lifting mechanism is preferably in two sets. During operation, the drive wheel 11 and the lifting mechanism on the wheel 11 rotate. Preferredly, one set of lifting mechanisms drives the robotic arm 3 and its clamping mechanism to descend and clamp the glass plate. Then, the wheel 11 continues to rotate, and the lifting mechanism of the set of glass plates lifts and lowers to transport the glass plate to a designated position for use. At this time, the other set of lifting mechanisms clamps the glass plate again, thus achieving simultaneous clamping and placement of the glass plate. This cycle repeats, saving a lot of labor costs and increasing the clamping speed.

[0033] Example 2

[0034] like Figure 4 As shown, a suction cup 44 is provided on the inner side of the clamping plate 42, preferably an electro-permanent magnet suction cup. An electro-permanent magnet suction cup refers to a suction cup that relies on a permanent magnet to generate attraction force and uses an excitation coil to control the attraction force of the magnet, thus acting as a suction force switch.

[0035] The magnetic circuit is closed by changing the direction of the current in the electromagnetic coil, thereby achieving the purpose of holding or unloading the workpiece. Since the electro-permanent magnet chuck is existing technology, its structure will not be described in detail.

[0036] When a single glass plate is being held, especially a large glass plate, the clamping plates 42 on opposite sides slide inward on the crossbar 41 to clamp the large glass plate. The glass plate is then adsorbed by the suction cup 44, thereby improving the stability of the glass plate adsorption and clamping. At this time, there is interference with the support plate 43. Therefore, the inner side of the clamping plate 42 is slotted, and the support plate 43 is rotatably connected to the slot of the clamping plate 42. When only one large glass plate needs to be clamped, the support plate 43 is stored in the slot of the clamping plate 42.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
