Description

Technical Field

[0001] This invention relates to the field of positioning technology, and in particular to a positioning mechanism device. Background Technology

[0002] Currently, carriers, as product transfer platforms, are used in automated production lines across various industries. The processes on automated production lines require precise positioning of the carriers to complete each process.

[0003] Patent CN214358383U discloses a line lifting and positioning mechanism. This patent requires a receiving cavity for installing a solenoid valve assembly at the bottom of the support plate, which has the drawback of inconvenience in replacing and maintaining the solenoid valve assembly. In addition, the sensor mounting assembly of this patent is located on the outside of the mechanism, which may lead to inaccurate sensing by the sensor. Furthermore, a protective sheet metal is required on the top of the sensor mounting assembly for protection, which increases the economic cost.

The solenoid valve in this patent is installed on the side of the frame, which is at risk of being damaged by collision. In addition, this patent uses a pressing mechanism to press down an object and then performs a pressing detection. The detection sensor also detects the object at the same time. However, since the detection sensor is located at the bottom side of the pressing mechanism, there is a possibility that the detection sensor is not accurate, resulting in a defect of inaccurate positioning.

[0027] The invention can be further understood through the specific embodiments given below, but they are not intended to limit the invention.

[0028] like Figures 1 to 2As shown, a positioning mechanism includes a mounting plate 1, a first side plate 2, and a second side plate 3. The first side plate 2 and the second side plate 3 clamp the mounting plate 1. Specifically, the mounting plate 1 is fixed between the first side plate 2 and the second side plate 3. A first check seat 4 is fixedly connected to the front end of the first side plate 2. A second check seat 5, with the same structure as the first check seat 4, is fixedly connected to the front end of the mounting plate 1 and near the front end of the second side plate 3. The first check seat 4 and the second check seat 5 constitute a check seat assembly. The function of the check seat assembly is to allow a product-carrying carrier to pass through the top of the check seat assembly and enter the mounting plate 1. The carriers mentioned below are all product-carrying carriers. After both sides of the rear end of the carrier have completely passed through the check seat assembly, the components on the check seat assembly will... The vehicle bounces up, preventing it from sliding backward. A first blocking cylinder support 6 and a second blocking cylinder support 7, fixedly connected to the mounting plate 1, are installed on both sides of the rear end of the mounting plate 1. The positions of the first blocking cylinder support 6 and the second blocking cylinder support 7 are symmetrically arranged. A first blocking cylinder 8 is installed on the first blocking cylinder support 6, and a second blocking cylinder 9 is installed on the second blocking cylinder support 7. The first blocking cylinder 8 and the second blocking cylinder 9 constitute a blocking cylinder assembly. The function of the blocking cylinder assembly is to prevent the vehicle on the mounting plate 1 from continuously moving forward under the action of power and falling off the mounting plate 1. Therefore, the function of the blocking cylinder assembly is to block the two sides of the front end of the vehicle, preventing it from moving forward indefinitely. Thus, the two sides of the front end of the vehicle are blocked. With the air-stopping cylinder assembly blocking the rear sides of the vehicle, the vehicle rests on the mounting plate 1. A proximity switch 10 is fixedly installed on the mounting plate 1 near the first side plate 2. The proximity switch 10 senses the position of the vehicle on the mounting plate 1. A positioning gripper 11 is also installed on the mounting plate 1. The positioning gripper 11 grips and positions the vehicle on the mounting plate 1. A first guide rail 110 is installed through the bottom of one side of the positioning gripper 11, and a second guide rail 111, parallel to the first guide rail 110, is installed through the bottom of the other side. Both the first guide rail 110 and the second guide rail 111 are linear guide rails. The positioning gripper 11 can move on the first guide rail 110 and the second guide rail 111, thereby allowing movement... For precise reciprocating positioning, a baffle 12 is installed on the mounting plate 1 near the positioning gripper 11. The purpose of the baffle 12 is to block and fix the position of the vehicle when the positioning gripper 11 is positioning it, preventing the vehicle from shifting position and improving positioning accuracy. A U-shaped sheet metal 13 is fixedly installed at the front end of the mounting plate 1. The U-shaped sheet metal 13 can protect the device and prevent the positioning mechanism from being impacted. An air pipe connector 14 is provided at the rear end of the mounting plate 1. The positioning mechanism takes in air from the air pipe connector 14. A positioning cylinder 15 is installed at the bottom of the mounting plate 1 and is fixedly connected to the positioning gripper 11. The purpose of the positioning cylinder 15 is to improve the positioning efficiency of the positioning gripper 11 on the vehicle and reduce positioning time.At the bottom of mounting plate 1, a solenoid valve assembly consisting of two solenoid valves 16 is fixedly installed and communicates with mounting plate 1. An air pipe connector 14 is connected to the solenoid valve assembly, and the air intake state of the air pipe connector 14 is controlled by the solenoid valve assembly. The two solenoid valves 16 are arranged in close parallel contact to form the solenoid valve assembly. In this device, to control parameters such as direction and speed of the carrier during positioning, installing the solenoid valve assembly at the bottom of mounting plate 1 makes the overall layout of the positioning mechanism more reasonable. The space occupied by the solenoid valve assembly at the bottom of mounting plate 1 is significantly reduced compared to existing technologies, which also facilitates the overall design and assembly of the positioning mechanism. An aviation connector 18 for connecting various electrical lines is also fixedly installed at the bottom of mounting plate 1.

[0029] like Figure 3 and Figure 4 As shown, the first check valve 4 includes a seat body 400 and a spring plate 401. The spring plate 401 is inserted into the seat body 400. It should be noted that the second check valve 5 has the same structure as the first check valve 4, and will not be described again here. The spring plate 401 has a certain elasticity. The function of the spring plate 401 is to prevent the vehicle from entering the mounting plate 1 after passing completely through the top surface of the check valve assembly composed of the first check valve 4 and the second check valve 5, thus preventing the vehicle from sliding backward. Specifically, as shown... Figure 4 As shown, when the vehicle passes the top surface of the anti-return seat assembly, the return spring 401 is pressed down into the seat body 400 and remains in a flat state, as shown. Figure 3 As shown, when the vehicle has completely passed the top surface of the check seat assembly and entered the mounting plate 1, the rebound piece 401 bounces upward under pressure, thus preventing the vehicle from sliding backward.

[0030] like Figure 5 As shown, the base 400 is designed with a U-shaped groove. This design can more securely fix the spring sheet 401 and prevent the spring sheet 401 from flying off due to excessive pressure.

[0031] like Figure 1 As shown, the first blocking cylinder 8 is fixedly connected to the first blocking cylinder support 6 via the first fixing ring 801, and the second blocking cylinder 9 is fixedly connected to the second blocking cylinder support 7 via the second fixing ring 901. Specifically, the first fixing ring 801 can stably fix the first blocking cylinder 8 on the first blocking cylinder support 6, and similarly, the second fixing ring 901 can stably fix the second blocking cylinder 9 on the second blocking cylinder support 7.

[0032] like Figure 1As shown, a first wheel 800 made of rubber is fixedly embedded in the top of the first blocking cylinder 8, and a second wheel 900 with the same structure as the first wheel 800 is fixedly embedded in the top of the second blocking cylinder 9. When the vehicle is large in volume and high in height, in order to prevent the vehicle from being damaged by the blocking cylinder group composed of the first blocking cylinder 8 and the second blocking cylinder 9, the first wheel 800 and the second wheel 900 made of rubber are fixedly embedded in the top of the first blocking cylinder 8 and the second blocking cylinder 9, respectively. The first wheel 800 and the second wheel 900 are both made of soft rubber and have a certain degree of elasticity, which can protect the vehicle from damage.

[0033] like Figure 6 As shown, the proximity switch 10 includes a fixed base 100 and a support body 101 fixedly connected to the fixed base 100. A sensing probe 102 is provided at one end of the support body 101, and a start button 104 is provided on the surface of the support body 101. Specifically, when the positioning mechanism is started, the start button 104 on the proximity switch 10 is turned on, and the proximity switch 10 is in the running state. When the vehicle moves to the mounting plate 1, the probe 102 can sense it. The sensing probe 102 is installed in a telescopic spiral rod 103 fixedly connected to one end of the support body 101. Specifically, the sensing probe 102 can extend and retract together with the spiral rod 103, changing the length of the sensing probe 102. Thus, the sensing probe 102 can automatically change its length according to the size of the vehicle, thereby sensing the vehicle more accurately.

[0034] like Figure 2 As shown, the positioning cylinder 15 includes two cylinder valves 150. In order to further improve the positioning efficiency of the positioning gripper 11 on the carrier and reduce the positioning time, the positioning cylinder 15 is equipped with two cylinder valves 150. Similarly, in order to better control the direction, speed and other parameters of the carrier during positioning, each solenoid valve 16 is equipped with two regulating valves 17. Therefore, the solenoid valve group is equipped with two solenoid valves 16, and each solenoid valve 16 is equipped with two regulating valves 17.

[0035] like Figure 1 and Figure 2 As shown, the wiring of the positioning mechanism is electrically connected to the aviation connector 18. This arrangement can save a lot of wiring layout space and make the layout of the positioning mechanism more reasonable.

[0036] The working principle of the positioning mechanism in this embodiment is as follows:

[0037] When the positioning mechanism is activated, the carrier carrying the product enters the mounting plate 1 along the top surface of the check seat assembly consisting of the first check seat 4 and the second check seat 5. The front sides of the carrier are stopped by the blocking cylinder assembly consisting of the first blocking cylinder 8 and the second blocking cylinder 9. After the rear sides of the carrier are fully inside the mounting plate 1, the two spring plates 401 on the check seat assembly pop up instantly and abut against the rear sides of the carrier to prevent the carrier from sliding backward. After the blocking cylinder assembly stops the carrier, the sensing probe 102 on the proximity switch 10 immediately senses the position of the carrier. The positioning gripper 11 close to the proximity switch 10 grips and positions the carrier under the combined action of the positioning cylinder 15 and the solenoid valve assembly consisting of two solenoid valves 16. Under the action of the baffle 12, the carrier is fixed on the mounting plate 1, and the carrier is thus positioned.

[0038] The beneficial effects of this embodiment are as follows: ① The positioning mechanism can reduce material costs; ② The positioning mechanism can be modularly assembled, reducing assembly time and maintenance costs; ③ The connection between the mounting plate 1 and the solenoid valve group 14 reduces the overall size of the positioning mechanism, which is beneficial for its design and assembly; ④ The spatial layout of the positioning mechanism is reasonable, facilitating circuit layout and improving safety; ⑤ The design of the check seat group composed of the first check seat 4 and the second check seat 5 can prevent the carrier from slipping backward, reducing potential product damage; ⑥ The first The design of the blocking cylinder group consisting of blocking cylinder 8 and the second blocking cylinder 9 can effectively stop the vehicle and prevent it from falling off the mounting plate 1; ⑦ The setting of the first guide rail 110 and the second guide rail 111 can make the positioning gripper 11 move back and forth for precise reciprocating positioning; ⑧ The U-shaped sheet metal 13 can protect the device and prevent the positioning mechanism from being impacted; ⑨ The design of the first wheel 800 and the second wheel 900 can effectively protect the vehicle and prevent it from being damaged by collision; ⑩ The design of the sensing probe 102 and the screw rod 103 can improve the sensing accuracy of the proximity switch 10.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
