Description

Positioning device for transport vehicles Technical Field

[0001] This utility model belongs to the field of transportation equipment, specifically a positioning device for a transport vehicle. Background Technology

[0002] In the semiconductor product manufacturing process, transport vehicles are needed to connect to corresponding equipment to move semiconductor products from one production equipment to another. For example, after the leads of a semiconductor product are bent, a transport vehicle needs to be connected to the bending equipment to move the semiconductor product on the bending equipment to the next process for further processing.

[0003] In existing technologies, the transport vehicle is positioned by brakes on its casters. During the process of moving semiconductor products from the docking equipment to the transport vehicle, the transport vehicle and the docking equipment are in a separate state, resulting in a high misalignment rate between the transport vehicle and the docking equipment. Summary of the Invention

[0004] Purpose of the utility model: To provide a positioning mechanism for a transport vehicle, which connects or separates the transport vehicle from the docking equipment through a positioning device, thus solving the problem of high misalignment rate between the transport vehicle and the docking equipment in the prior art.

[0005] The technical solution of this utility model is: a positioning device for a transport vehicle, which is installed on the positioning device and the docking equipment.

[0006] The positioning device includes: a positioning plate, a guide shaft, a power source, a locking component, and a position sensor.

[0007] The positioning plate is installed on the transport vehicle, and the guide shaft, power source, and position sensor are installed on the docking equipment.

[0008] The positioning plate is provided with a guide groove and a locking part.

[0009] The guide shaft cooperates with the guide groove and is used to guide the positioning plate in the lateral direction.

[0010] The locking component is installed on a power source, which is used to drive the locking component to connect or separate from the locking part. The locking component is used to limit the positioning plate in the longitudinal direction.

[0011] The position sensor is used to detect the position of the transport vehicle.

[0012] In a further embodiment, the positioning device further includes a first positioning block.

[0013] The first positioning block is installed on the docking equipment.

[0014] When the transport vehicle moves to the position where it connects with the first positioning block, the first positioning block and the locking component cooperate to limit the positioning plate in the longitudinal direction.

[0015] In a further embodiment, the locking element includes a hinge structure and a locking hook.

[0016] The power source is a linear power source extending longitudinally. The hinge structure and the locking hook are installed on the linear power source. The linear power source drives the locking hook to rotate through the hinge structure, so that the locking hook can be engaged or disengaged from the locking part. By rotating the locking hook and engaging with the locking part, the fitting accuracy of the locking part and the positioning plate can be reduced.

[0017] In a further embodiment, the position sensor is a non-contact position sensor.

[0018] In a further embodiment, the non-contact position sensor is a photoelectric position sensor or an electromagnetic induction sensor. Using a non-contact position sensor to detect the position of the transport vehicle reduces the probability of the sensor being damaged by a collision. Compared with the prior art that uses proximity switches to realize the positioning detection of the transport vehicle, it solves the problem that the proximity switch distance is difficult to adjust and the proximity switch is easily damaged by a collision.

[0019] In a further embodiment, the positioning device further includes a second positioning block and a pin.

[0020] The second positioning block is installed on the transport vehicle, and the second positioning block is provided with positioning holes.

[0021] The pin is installed on the docking device, and the pin extends longitudinally.

[0022] When the guide shaft mates with the guide groove, the pin is inserted into the positioning hole. The cooperation between the first positioning block and the pin enables the transport vehicle to be precisely positioned, while the guide shaft and guide groove are coarsely positioned, reducing the difficulty of mates between the guide shaft and guide groove.

[0023] In a further embodiment, the positioning hole and / or the pin is provided with a guide structure for guiding the pin.

[0024] The beneficial effects of this utility model are as follows: This application guides the positioning plate in the lateral direction by cooperating with the guide shaft and the guide groove, and after the position sensor detects the position of the transport vehicle in the lateral and longitudinal directions, the power source controls the locking part to connect or separate from the locking part. This enables the guide shaft to limit the positioning plate in the lateral direction and the locking part to limit the positioning plate in the longitudinal direction. It can connect with the docking equipment when the transport vehicle moves to the predetermined position, which solves the problem of high misalignment rate between the transport vehicle and the docking equipment in the prior art, where the transport vehicle and the docking equipment are in a separate state.

[0037] The positioning plate 1 is provided with a guide groove and a locking part. As shown in Figure 2, the guide groove of the positioning plate 1 is provided with an arc guide structure, and the locking part is a strip structure formed by openings at a predetermined distance from the side. In other embodiments, the guide groove can also be provided with an angled guide structure, and the locking part can also be a rod installed on the positioning plate 1.

[0038] The guide shaft 2 cooperates with the guide groove and is used to guide the positioning plate 1 in the lateral direction. As shown in Figure 1, the guide shaft 2 is a vertical shaft.

[0039] The locking component 4 is installed on the power source 3. The power source 3 is used to drive the locking component 4 to connect or separate from the locking part. The locking component 4 is used to limit the positioning plate 1 in the longitudinal direction.

[0040] The position sensor 5 is used to detect the position of the transport vehicle 9. The docking equipment 10 includes control devices such as a PLC. The position sensor 5 and the power source 3 can cooperate with the control devices such as the PLC of the docking equipment 10.

[0041] As shown in Figure 1, the positioning device also includes: a first positioning block 6.

[0042] The first positioning block 6 is installed on the docking device 10.

[0043] When the transport vehicle 9 moves to the position where it connects with the first positioning block 6, the first positioning block 6 and the locking member 4 cooperate to limit the positioning plate 1 in the longitudinal direction.

[0044] As shown in Figure 3, the locking component 4 includes a hinge structure 41 and a locking hook 42.

[0045] The power source 3 is a linear power source 3 that extends longitudinally. The hinge structure 41 and the locking hook 42 are installed on the linear power source 3. The linear power source 3 drives the locking hook 42 to rotate through the hinge structure 41, so that the locking hook 42 is connected or separated from the locking part. As shown in Figure 1, the linear power source 3 is a cylinder. In other embodiments, a combination of a motor and a lead screw mechanism can also be used to form the linear power source 3.

[0046] In other embodiments, a linear power source 3 can be connected to a vertical pin 8, so that the linear power source 3 drives the pin 8 to be inserted into the positioning plate 1 from the vertical direction.

[0047] Position sensor 5 is a non-contact position sensor.

[0048] The non-contact position sensor 5 is either a photoelectric position sensor or an electromagnetic induction sensor.

[0053] The positioning hole and / or the pin 8 are provided with a guide structure, which is used to guide the pin 8. As shown in Figure 4, the pin 8 is provided with a chamfer as a guide structure.

[0054] Instructions for use: When the transport vehicle 9 moves the guide groove of the positioning plate 1 to the position where it mates with the guide shaft 2, the guide shaft 2 guides the positioning plate 1 in the lateral direction, and in turn guides the transport vehicle 9 in the lateral direction.

[0055] While guiding the transport vehicle 9 in the lateral direction, the transport vehicle 9 is further moved in the longitudinal direction towards the docking device 10. When the transport vehicle 9 moves to the position where the guide shaft 2 and the positioning plate 1 are engaged as shown in Figure 2, the position sensor 5 detects that the transport vehicle 9 has moved to the positioning position. The position sensor 5 sends an electrical signal to the linear power source 3, causing the linear power source 3 to drive the hinge structure 41 and the locking hook 42 to move and rotate the locking hook 42 to the position where it engages with the locking part.

[0056] When it is necessary to move the transport vehicle 9 out, an electrical signal can be sent to the linear power source 3 through the button and control device of the docking device 10, so that the linear power source 3 drives the hinge structure 41 and the locking hook 42 to move and rotate the locking hook 42 to the position where it is separated from the locking part.

[0057] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
