Description

Technical Field

[0001] This utility model belongs to the field of suction cup holder technology, and in particular relates to a suction cup holder with high safety. Background Technology

[0002] A vacuum suction cup holder is a device used to fix and support vacuum suction cups, usually made of metal. Its main function is to provide a stable platform so that the vacuum suction cup can be accurately attached to the surface of an object, thereby performing various operations such as handling, positioning, and spraying.

[0003] Chinese utility model patent with publication number CN201952010U discloses a suction cup frame for a glass stacker. During the glass handling process, if the glass collides with another glass, the suction cup frame cannot detect the collision and take appropriate action. This causes the suction cup frame to continue running after the collision, which can easily damage both the glass and the suction cup frame, reducing the safety of the suction cup frame.

[0004] Therefore, it is necessary to improve the suction cup holder in the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a suction cup holder with high safety, thereby improving the safety of the suction cup holder.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a highly secure suction cup holder is as follows:

[0007] A high-safety suction cup holder includes a mounting frame, on which a plurality of vacuum suction cups are evenly distributed. A first direction is defined as the direction perpendicular to the plane of the mounting frame. The vacuum suction cups are slidably connected to the mounting frame along the first direction. An elastic connector is provided between the vacuum suction cups and the mounting frame.

[0008] The mounting bracket is also slidably provided with a top rod along a first direction, and an elastic reset member is provided between the top rod and the mounting bracket. The mounting bracket is provided with a sensor for detecting the position of the end of the top rod.

[0009] Preferably, the vacuum suction cup is fixedly connected to a vent pipe distributed along a first direction, and a mounting sleeve that is fixedly connected to the mounting bracket is slidably fitted on the vent pipe. The elastic connector is disposed between the mounting sleeve and the vacuum suction cup.

[0010] Preferably, a cylinder is provided on the mounting sleeve along the first direction, the front end of the vent pipe is connected to the vacuum suction cup, a limiting gasket is fixedly connected to the end of the vent pipe, a transmission component that slides with the vent pipe is provided between the limiting gasket and the mounting sleeve, and the transmission component is connected to the telescopic end of the cylinder.

[0011] Preferably, the transmission member has a notch for the vent pipe to enter, and the width of the limiting gasket is greater than the width of the notch.

[0012] Preferably, the elastic connector is a first spring, which is sleeved on the vent pipe. The first spring is in a compressed state, and its two ends abut against the mounting sleeve and the vacuum suction cup, respectively.

[0013] Preferably, a sliding sleeve that is fixedly connected to the mounting bracket is slidably fitted on the top rod, and the elastic reset member is disposed between the sliding sleeve and the top rod.

[0014] Preferably, a flexible anti-collision block is fixedly connected to the front end of the top rod.

[0015] Preferably, the mounting frame includes mutually perpendicular horizontal beams and vertical beams, with multiple vertical beams arranged at equal intervals along the extension direction of the horizontal beams, and each vacuum suction cup arranged at equal intervals on each of the vertical beams.

[0016] Preferably, multiple top rods are provided, and each top rod is evenly distributed on the mounting frame.

[0017] Preferably, the bottom of the vacuum suction cup is provided with an anti-slip block.

[0018] The high-safety suction cup holder of this utility model has the following advantages: During the process of the suction cup holder moving glass, if a collision occurs, the glass will push the top rod to move under the force of the collision. When the sensor detects the displacement of the top rod, it is determined that the glass has collided, and the suction cup holder will stop, thereby avoiding damage to the glass and the suction cup holder and improving the safety of the suction cup holder. At the same time, under the buffering effect of the elastic connector, the impact force on the glass can be absorbed, thereby reducing the probability of glass damage. Attached Figure Description

Detailed Implementation

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the suction cup holder and are only for the purpose of facilitating the description of this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] like Figure 1-4 As shown, a high-safety suction cup holder includes a mounting frame 1. Multiple vacuum suction cups 204 are evenly distributed on the mounting frame 1. The direction perpendicular to the plane of the mounting frame 1 is the first direction. The vacuum suction cups 204 are slidably connected to the mounting frame 1 along the first direction. An elastic connecting member is provided between the vacuum suction cups 204 and the mounting frame 1. The mounting frame 1 is also slidably provided with a push rod 303 along the first direction. An elastic reset member is provided between the push rod 303 and the mounting frame 1. The mounting frame 1 is provided with a sensor 305 for detecting the position of the end of the push rod 303.

[0027] The aforementioned suction cup holder is suitable for handling glass. During use, each vacuum suction cup 204 adheres to the glass, securing the suction cup holder to the glass. The suction cup holder then moves the glass, enabling the handling operation. During handling, if the glass collides with the side away from the mounting bracket 1, the impact force causes the glass to move towards the mounting bracket 1. At this time, the glass pushes the push rod 303 towards the sensor 305. When the sensor 305 detects the push rod 303, it sends a signal to the suction cup holder's control system, which then... The suction cup holder is controlled to stop moving to prevent further aggravation of the collision, reduce the probability of damage to the glass and the suction cup holder, and improve the safety of the suction cup holder. The elastic connector on the vacuum suction cup 204 generates enough elastic force to offset the weight of the glass, so that the weight of the glass is not enough to cause the push rod 303 to be falsely triggered, thereby improving the accuracy of the suction cup holder in collision detection. In addition, the elastic connector also plays a buffering role. When the glass collides, the elastic force of the elastic connector can offset part of the impact force to reduce the impact force on the glass and reduce the probability of glass damage.

[0028] Further improvements include, for example Figure 2 As shown, a vacuum suction cup 204 is fixedly connected to a vent pipe 202 distributed along a first direction. A mounting sleeve 201, which is fixedly connected to the mounting bracket 1, is slidably fitted on the vent pipe 202. An elastic connector is disposed between the mounting sleeve 201 and the vacuum suction cup 204. A cylinder 205 is disposed on the mounting sleeve 201 along the first direction. The front end of the vent pipe 202 is connected to the vacuum suction cup 204. A limiting gasket 207 is fixedly connected to the end of the vent pipe 202. A transmission component 206, which is slidably fitted with the vent pipe 202, is disposed between the limiting gasket 207 and the mounting sleeve 201. The transmission component 206 is connected to the telescopic end of the cylinder 205.

[0029] Specifically, the mounting sleeve 201 is used to connect the vent pipe 202 to the mounting bracket 1, and also provides support and guidance for the movement of the vent pipe 202. A limiting gasket 207 is provided at the end of the vent pipe 202 to prevent it from falling out of the mounting sleeve 201 under the action of the first spring 203. One end of the vent pipe 202 is connected to the inside of the suction cup 204, and the other end is connected to the vacuum pump. The vacuum pump can extract the air inside the vacuum suction cup 204 to achieve the adsorption of the glass by the vacuum suction cup 204.

[0030] The suction cup holder is typically moved by a robotic arm. When adsorbing glass from a conveyor belt, the movement of the suction cup holder needs to be synchronized with the movement of the glass, and relative to the glass as well. Precise control of the suction cup holder's movement in multiple directions simultaneously places high demands on the robotic arm, requiring the purchase of a high-precision robotic arm, which increases the production cost of the suction cup holder. To address this, a cylinder 205 and a first spring 203 are used in combination to control the vent pipe 202 to move axially along the mounting sleeve 201, thereby controlling the vacuum suction cup 204. The movement of the vacuum suction cup 204, when the suction cup holder moves synchronously with the glass, can replace the movement of the robotic arm along the axial direction of the ventilation pipe 202, thereby reducing the requirement for the control precision of the robotic arm, thus saving the purchase cost of the robotic arm and reducing the usage cost of the suction cup holder; the combination of the first spring 203 and the cylinder 205 can increase the speed of the vacuum suction cup 204 moving along the axial direction of the ventilation pipe 202 by selecting a cylinder 205 with a faster response speed, thereby accelerating the docking speed between the vacuum suction cup 204 and the glass, reducing the displacement of the robotic arm and improving work efficiency.

[0031] The transmission component 206 is slidably connected to the vent pipe 202, so that the vent pipe 202 can not only be moved by the cylinder 205, but also move independently under the action of external force. Thus, when the glass is hit, the movement of the vent pipe 202 can be coordinated with the push rod 303 to trigger the action.

[0032] Further improvements include, for example Figure 3 As shown, the transmission component 206 has a notch 209 for the vent pipe 202 to enter, and the width of the limiting gasket 207 is greater than the width of the notch 209. The notch 209 improves the ease of disassembly and assembly between the transmission component 206 and the vent pipe 202, thereby improving the ease of equipment maintenance.

[0033] Further improvements include, for example Figure 2 As shown, the elastic connector is a first spring 203, which is sleeved on the vent pipe 202. The first spring 203 is in a compressed state, and its two ends abut against the mounting sleeve 201 and the vacuum suction cup 204, respectively. The first spring 203 can act as a buffer during the process of the vacuum suction cup 204 adsorbing the glass, thereby reducing the interaction force between the glass and the vacuum suction cup 204 and reducing the probability of glass damage. During the process of glass collision, it can also act as a buffer for the glass, further reducing the probability of glass damage. In addition, the first spring 203, in cooperation with the cylinder 205, can also control the movement of the vent pipe 202, thereby adjusting the position of the vacuum suction cup 204.

[0034] Further improvements include, for example Figure 4As shown, a sliding sleeve 304 is slidably fitted on the top rod 303 and fixedly connected to the mounting bracket 1, and an elastic reset member is disposed between the sliding sleeve 304 and the top rod 303. A limit nut is provided at the end of the push rod 303 to prevent the push rod 303 from falling out of the sliding sleeve 304. The elastic reset element is a second spring 302, which is sleeved on the outer periphery of the push rod 303. The second spring 302 is in a compressed state, and its two ends abut against the front end of the push rod 303 and the sliding sleeve, respectively. When the glass collides, the glass pushes the push rod 303 to move in the direction of the sensor 305. When the end of the push rod 303 moves to the front of the detection end of the sensor 305, the sensor 305 detects the push rod 303 and sends a signal to the control system of the suction cup frame. The control system controls the suction cup frame to stop at the current position. If the glass being transported does not collide, the second spring 302 controls the push rod 303 to reset. In the reset state, the end of the push rod 303 moves away from the front of the detection end of the sensor 305, and the sensor 305 is in the detection state and will not be triggered.

[0035] Further improvements include, for example Figure 4 As shown, a flexible anti-collision block 301 is fixedly connected to the front end of the top rod 303. The flexible anti-collision block 301 can be a rubber block, which can protect the end of the top rod 303 and reduce the mutual wear between the top rod 303 and the glass.

[0036] Further improvements include, for example Figure 1 As shown, the mounting frame 1 includes mutually perpendicular horizontal beams 101 and vertical beams 102. Multiple vertical beams 102 are provided and are arranged at equal intervals along the extension direction of the horizontal beams 101. Vacuum suction cups 204 are equally spaced on each vertical beam 102. Both the horizontal beams 101 and the vertical beams 102 are made of aluminum profiles and are fixed to each other with bolts. This increases the strength of the mounting frame 1, reduces its weight, and improves the ease of use of the suction cup holder; it also facilitates the disassembly and maintenance of the mounting frame 1.

[0037] Further improvements include, for example Figure 1 As shown, multiple push rods 303 are provided, and each push rod 303 is evenly distributed on the mounting frame 1. The multiple evenly distributed push rods 303 have a wider distribution range on the suction cup frame, which can detect glass of different sizes adsorbed at different positions on the suction cup frame, thereby improving the accuracy of the suction cup frame for collision detection and further improving the safety of the suction cup frame.

[0038] Further improvements include, for example Figure 3 As shown, the bottom of the vacuum suction cup 204 is provided with an anti-slip block 208. The anti-slip block 208 increases the friction between the vacuum suction cup 204 and the glass, reduces the chance of the glass slipping after being sucked up, thereby reducing the chance of the glass falling off and improving the firmness of the suction cup holder in adhering to the glass.
