Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a double-suction and double-release manipulator for an automatic test line. Background Art

[0002] During the operation of the automatic test line, it is necessary to transport and move the products, samples or parts to be tested. The robot can accurately grab, move and place these materials to ensure that they are processed according to the predetermined steps and positions. There are often multiple test points or equipment on the test line. Each test point requires corresponding samples for testing. The robot can accurately place the samples to be tested on the designated test points or equipment to ensure the continuity and accuracy of the test.

[0003] Most existing manipulators are adsorption devices powered by a set of adsorption equipment, which use suction cups to absorb objects through negative pressure to achieve grasping and carrying. However, when such adsorption devices fail and lose their adsorption capacity, they cannot stably grasp the objects to be carried, which will cause the objects to fall or unstable handling, affecting the automatic detection line's detection of products. Therefore, those skilled in the art provide a double-suction and double-release manipulator for an automatic test line to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes a double-suction and double-release manipulator for an automatic test line.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-suction and double-release manipulator for an automatic test line, comprising a manipulator body, air pump one and air pump two, a mounting plate is provided on one side of the lower end of the manipulator body, air pump one and air pump two are provided on the upper end of the manipulator body, an outer suction cup is provided inside the mounting plate, an inner suction cup is provided inside the outer suction cup, an outer suction pipe is installed through the outer suction cup, and an inner suction pipe is installed through the inner suction cup, the suction end of the air pump one is connected to air pipe one, and the suction end of the air pump two is provided with air pipe two, a protective box is sleeved on the outer side of the mounting plate, a motor is provided on one side of the upper end of the mounting plate, a screw is provided on the output end of the motor, and a guide rod is provided on the upper end of the mounting plate away from the motor.

[0006] Preferably, the first and second air pipes are both provided with pressure-compensating pipes, and the pressure-compensating pipes are provided with electromagnetic valves. The pressure-compensating pipes compensate the pressure inside the first and second air pipes, and the opening and closing of the pressure-compensating pipes are controlled by the electromagnetic valves.

[0007] Preferably, the outer suction cup and the inner suction cup are symmetrically distributed inside the two ends of the mounting plate, the outer suction pipe and the air pipe 1 are mutually connected, the inner suction pipe and the air pipe 2 are mutually connected, and the lower ends of the outer suction cup and the inner suction cup are both located at the same horizontal height. The outer suction cup is connected to the air pipe 1 through the outer suction pipe, and the inner suction cup is connected to the air pipe 2 through the inner suction pipe. The suction force of the air pump 1 acts on the inside of the outer suction cup, and the suction force of the air pump 2 acts on the inside of the inner suction cup.

[0008] Preferably, the upper and lower ends of the protection box are open, and a limit ring is provided on the upper end of the screw rod. When the protection box moves longitudinally, the limit ring effectively limits the threaded slider through the mounting plate to prevent the threaded slider from completely separating from the outer wall of the screw rod.

[0009] Preferably, a sliding sleeve is provided on the inner wall of one side of the protection box, and the sliding sleeve is slidably connected to the outer wall of the guide rod. The protection box is slidably connected to the outer wall of the guide rod through the sliding sleeve, so as to guide the protection box to move longitudinally.

[0010] Preferably, a threaded block is provided on the inner wall of one side of the protection box, and one end of the screw is rotatably inserted into the threaded block. The screw is adapted to the thread inside the threaded block, and when the screw rotates, the protection box is guided by the sleeve to push the inside of the threaded block.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model arranges an inner suction cup inside the outer suction cup, and when the automatic test line detects the product, the same position is adsorbed with double adsorption force, thereby increasing the overall adsorption force. The inner suction cup and the outer suction cup work together to more firmly grasp the object and prevent it from being loosened due to vibration or other forces. Since the adsorption force is provided by two sets of independently operated devices, if one set fails or fails, the other set can still be used to provide adsorption force. The redundancy of adsorption force improves the reliability of the entire system and reduces the impact of potential interruptions and failures.

[0013] At the same time, when the product is adsorbed and transported by the robot, the protective box descends through the longitudinal drive device to protect the outside of the product and avoid damage to the product due to collision during the transportation process.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 4 As shown, the utility model proposes a double-suction and double-release manipulator for an automatic test line, comprising a manipulator body 1, an air pump 1 3 and an air pump 2 5, a mounting plate 2 is arranged on one side of the lower end of the manipulator body 1, an air pump 1 3 and an air pump 2 5 are arranged on the upper end of the manipulator body 1, an outer suction cup 7 is arranged inside the mounting plate 2, an inner suction cup 10 is arranged inside the outer suction cup 7, an outer suction pipe 8 is installed through the outer suction cup 7, and an inner suction pipe 9 is installed through the inner suction cup 10, the suction end of the air pump 1 3 is connected with the air pipe 1 4, the suction end of the air pump 2 5 is arranged with the air pipe 2 6, the air pipe 1 4 and the air pipe 2 6 are both provided with a pressure compensation pipe, and the pressure compensation pipe is provided with an electromagnetic valve, the outer suction cup 7 and the inner suction cup 10 are symmetrically distributed inside the two ends of the mounting plate 2, the outer suction pipe 8 and the air pipe 1 4 are mutually connected, the inner suction pipe 9 and the air pipe 2 6 are mutually connected, and the lower ends of the outer suction cup 7 and the inner suction cup 10 are both located at the same horizontal height.

[0022] Implementation steps based on Example 1: When the product is tested on the automatic test line, it is transported by a manipulator. During the transport process, the outer suction cup 7 and the inner suction cup 10 are simultaneously attached to both sides of the upper end of the product, and the air pump 1 3 and the air pump 2 5 operate to generate suction force. The suction force of the air pump 1 3 acts on the inside of the outer suction cup 7, and the suction force of the air pump 2 5 acts on the inside of the inner suction cup 10, and double adsorption is performed. When the object is transported to the testing equipment, the pressure compensation pipe is opened by the electromagnetic valve, so that the air pipe 1 4 and the air pipe 2 6 are connected to the outside world, and the outer suction cup 7 and the inner suction cup 10 connected thereto are filled with air pressure, and the product is adsorbed by contact;

[0023] During the process of automatic inspection of the product, double suction and double release are realized. The combined action of the inner suction cup 10 and the outer suction cup 7 can improve the stability of the object. When the manipulator is carrying the object, the adsorption force is more evenly distributed and the object is less likely to slip, thereby ensuring the stability of the grasping and carrying process. Even if the outer suction cup 7 loses its adsorption force due to unexpected factors or operational errors, the inner suction cup 10 can maintain the grasping state of the object to prevent the object from suddenly falling and affecting the inspection of the product by the automatic test line.

[0024] like Figure 1-Figure 4 As shown, compared with the first embodiment, the double suction and double release manipulator for automatic test line proposed by the utility model also includes: a protective box 11 is sleeved on the outer side of the mounting plate 2, a motor 12 is arranged on one side of the upper end of the mounting plate 2, a screw 13 is arranged on the output end of the motor 12, a guide rod 16 is arranged on the side of the upper end of the mounting plate 2 away from the motor 12, the upper and lower ends of the protective box 11 are open, a limiting ring 15 is arranged on the upper end of the screw 13, a sliding sleeve 17 is arranged on the inner wall of one side of the protective box 11, and the sliding sleeve 17 is slidably sleeved on the outer wall of the guide rod 16; a threaded block 14 is arranged on the inner wall of one side of the protective box 11, and one end of the screw 13 is rotatably inserted into the inside of the threaded block 14.

[0025] In this embodiment, after the product is adsorbed and lifted, the motor 12 drives the screw 13 to rotate, and the protective box 11 moves longitudinally. When the screw 13 rotates, because the protective box 11 is guided by the sleeve 17, the inside of the threaded block 14 is pushed, and the protective box 11 descends to shield the outside of the product. In the automatic test line, the product is protected during the process of the robot body 1 moving the product to avoid collision and damage to the product. In the automatic test line, the robot body 1 is safer for moving the product. Before the robot body 1 places the product, the protective box 11 is lifted to effectively place the product.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
