Description

Technical Field

[0001] This utility model relates to the field of glass processing tools, and in particular to a positioning device. Background Technology

[0002] In the glass trimming process on a manual production line, the glass is fixed on a turntable for processing. After trimming, the turntable needs to be locked in a designated position for the robotic arm to grasp. The traditional method is to use photoelectric sensors to detect the sensing module on the turntable to trigger the air brake disc. However, the trimming process requires multiple rotations of the turntable, causing the sensing module to repeatedly pass through the sensor, resulting in frequent release of the air brake disc, which restricts the increase in production capacity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a positioning device to prevent the brake from starting during the trimming process.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a positioning device, including a brake, wherein the brake has a rotating shaft.

[0005] A turntable, which is connected to a rotating shaft, and a trigger block is provided on the turntable;

[0006] A switch having a trigger end that moves toward a trigger block, the switch being electrically connected to a brake.

[0007] Furthermore, the aforementioned positioning device also includes a linear reciprocating device, which has a movable end that moves toward the trigger block, and the trigger end of the switch is hinged to the movable end of the linear reciprocating device.

[0008] Furthermore, the linear reciprocating device includes a driver and a push block; the push block is connected to the driving end of the driver, and the trigger end of the switch is hinged to the push block.

[0009] Furthermore, the linear reciprocating device also includes a guide rail, and the push block is slidably connected to the guide rail.

[0010] Furthermore, the aforementioned positioning device also includes a limiting block, which forms a limiting space with the trigger end of the switch.

[0011] Furthermore, the switch consists of two conductive strips, with a conductive space formed between the trigger ends of the two conductive strips, and the trigger block is a conductive conductor.

[0012] Furthermore, the switch has at least an arcuate surface at its trigger end, and the trigger block is provided with a metal bearing capable of contacting the arcuate surface.

[0013] Furthermore, a vacuum suction cup is provided on the end face of the turntable away from the brake.

[0014] Furthermore, the vacuum suction cup is equipped with a pressure sensor, which is electrically connected to the brake.

[0015] Furthermore, the brake is an FZK type magnetic powder brake.

[0016] The beneficial effects of this utility model are as follows: a trigger block is set on the turntable, and a switch electrically connected to the brake is configured. During the trimming process, the trigger end of the switch is moved to a clearance position so that the trigger block cannot contact the trigger end when the turntable rotates, thereby preventing the brake from being accidentally activated; after the trimming is completed, the trigger end of the switch is moved to the trigger position. When the turntable rotates to the specified position, the trigger block contacts the trigger end, which triggers the brake to apply the brakes. Attached Figure Description

[0027] To explain in detail the purpose and effects achieved by the technical content of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 3As shown, the present invention provides a positioning device, including a brake 1, a turntable 2 and a switch 3. The brake 1 has a rotating shaft 11, the turntable 2 is connected to the rotating shaft 11, and the turntable 2 is provided with a trigger block 21. The switch 3 has a trigger end that moves toward the trigger block 21, and the switch 3 is electrically connected to the brake 1.

[0029] Working principle: A trigger block 21 is set on the turntable 2, and a switch 3 electrically connected to the brake 1 is configured. During the trimming process, the trigger end of the switch 3 is moved to the avoidance position so that the trigger block 21 cannot contact the trigger end when the turntable 2 rotates, thereby preventing the brake 1 from being activated accidentally. After the trimming is completed, the trigger end of the switch 3 is moved to the trigger position. When the turntable 2 rotates to the specified position, the trigger block 21 contacts the trigger end, which triggers the brake 1 to brake.

[0030] It is worth noting that brake 1 preferably uses an FZK type magnetic powder brake. The rotor of the FZK type magnetic powder brake is subjected to a magnetic field, which makes the rotor evenly stressed and the braking smoother. Of course, brake 1 can also use air brake discs or other braking devices.

[0031] Please refer to Figure 1 As shown, the positioning device further includes a linear reciprocating device 4, which has a movable end that moves toward the trigger block 21, and the trigger end of the switch 3 is hinged to the movable end of the linear reciprocating device 4.

[0032] As can be seen from the above description, the linear reciprocating device 4 controls the movement of the switch 3.

[0033] Please refer to Figures 2 to 4 As shown, the linear reciprocating device 4 further includes a driver 41 and a pusher block 42; the pusher block 42 is connected to the driving end of the driver 41, and the trigger end of the switch 3 is hinged to the pusher block 42.

[0034] As can be seen from the above description, the linear reciprocating device 4 drives the push block 42 to move through the driver 41, thereby realizing the swinging activity of the switch 3.

[0035] Please refer to Figures 2 to 4 As shown, the linear reciprocating device 4 further includes a guide rail 43, and the push block 42 is slidably connected to the guide rail 43.

[0036] As can be seen from the above description, the guide rail 43 ensures the direction of movement of the push block 42.

[0037] Please refer to Figure 2 and Figure 3 As shown, the positioning device further includes a limiting block 5, which forms a limiting space with the trigger end of the switch 3.

[0038] As described above, during the trimming process, the retraction of the trigger end of switch 3 maximizes the width of the limiting space between the limiting block 5 and the trigger end of switch 3, allowing trigger block 21 to pass directly through the limiting space without affecting the normal rotation of turntable 2. When positioning turntable 2, the extension of the trigger end of switch 3 minimizes the width of the limiting space between the limiting block 5 and the trigger end of switch 3, ensuring that trigger block 21 can contact the trigger end of switch 3 to trigger brake 1.

[0039] Please refer to Figure 2 and Figure 3 As shown, the switch 3 further comprises two conductive strips, with a conductive space 6 formed between the trigger ends of the two conductive strips, and the trigger block 21 is a conductive conductor.

[0040] As described above, during the positioning turntable 2 process, the trigger block 21 moves into the conductive space 6, connecting the circuit between the two conductive strips to trigger the brake 1 to perform braking operation.

[0041] Please refer to Figure 3 As shown, the switch 3 has at least an arc surface at its trigger end, and the trigger block 21 is provided with a metal bearing 211 that can contact the arc surface.

[0042] As described above, during the positioning of the turntable 2, the metal bearing 211 rolls on the switch 3 to increase the resistance to the rotation of the turntable 2, so that the operator knows that the trigger block 21 is about to enter the conduction space 6, so that the operator can reduce the rotation speed of the turntable 2 and ensure that the brake 1 can be smoothly triggered to brake in the future.

[0043] Please refer to Figure 1 As shown, the turntable 2 is further provided with a vacuum suction cup 22 on the end face away from the brake 1.

[0044] As can be seen from the above description, the glass is fixed on the turntable 2 by the vacuum suction cup 22.

[0045] Furthermore, the vacuum suction cup 22 is equipped with a pressure sensor (not shown in the figure), which is electrically connected to the brake 1.

[0046] As described above, a pressure sensor is used to detect the working pressure of the vacuum suction cup 22 to determine whether the vacuum suction cup 22 is effectively adsorbing the glass, so as to prevent the turntable 2 from rotating if the glass is not effectively adsorbed.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
