[0002] In the process of PCB sheet processing, the PCB sheet is generally fixed on the processing table by pins, and then processed by PCB sheet processing equipment. After the processing is completed, the pins are removed and the PCB sheet is processed subsequently. This method has the following problems:

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 3 As shown, a positioning and locking mechanism for PCB processing includes a positioning component 1 and a locking component 2, wherein the positioning component 1 extends into the locking component 2 by moving downward, and the locking component 2 includes a locking cylinder 21 provided with a locking piston rod 211, and a locking seat 22 is provided on the locking cylinder 21, and a locking piece 23 extending to the inner side of the locking seat 22 is provided at one end of the locking seat 22 away from the locking cylinder 21, and the locking piston rod 211 is connected to the locking piece 23 and drives the locking piece 23 to move up and down in the locking seat 22, and when the positioning component 1 extends to the inner side of the locking piece 23 by moving downward, the locking piece 23 locks the positioning component 1 as the locking piston rod 211 moves downward.

[0023] In this embodiment, the positioning assembly 1 includes a positioning connection disk 11 and a tapered handle 12 disposed below the positioning connection disk 11 .

[0024] In this embodiment, a locking through hole 221 is formed inside the locking seat 22 , and the locking member 23 moves up and down inside the locking through hole 221 as the locking piston rod 211 moves up and down.

[0025] In this embodiment, the locking member 23 includes a locking cylinder 231, and a locking portion 232 is provided at one end of the locking cylinder 231 away from the locking seat 22. The locking portion 232 is provided with a locking cavity 233 that matches the shape and size of the conical handle 12. When the conical handle 12 extends to the inner side of the locking cavity 233 by moving downward, the locking cavity 233 locks the conical handle 12 as the locking piston rod 211 moves downward.

[0026] In this embodiment, the locking portion 232 has a plurality of auxiliary locking grooves 234 extending downward to the middle of the locking column 231 and communicating with the locking cavity 233 on the top thereof. The auxiliary locking grooves 234 divide the locking portion 232 into a plurality of independent locking petals 235 .

[0027] In this embodiment, the outer diameter of the locking column 231 is smaller than the inner diameter of the locking through hole 221 , and the outer diameter of the locking portion 232 is larger than the inner diameter of the locking through hole 221 .

[0028] This mechanism is used for positioning and locking during the processing of PCB sheets, and it needs to be used with a device such as a bakelite board base to fix the PCB sheets during the processing of PCB sheets. The positioning component 1 is installed on the bottom of the bakelite board base through the positioning connection plate 11, and the locking component 2 is installed on the main body of the PCB processing equipment through the cylinder body of the locking cylinder 21. Before processing the PCB sheets, the bakelite board base with the PCB sheets installed is first transported to the top of the main body of the PCB processing equipment by a handling device such as a manipulator to ensure that the positioning component 1 is aligned with the locking component 2. Subsequently, the handling device moves downward to insert the cone handle 12 into the locking piece 23; since the locking auxiliary groove 234 divides the locking portion 232 into several independent locking petals 235, it is easier to insert the cone handle 12 into the locking piece 23. After the cone handle 12 is inserted into the locking member 23, the locking piston rod 211 of the locking cylinder 21 moves downward, and at the same time drives the locking member 23 to move downward. During the downward movement of the locking member 23, the outer wall of the locking column 231 contacts the inner wall of the locking seat 22 and completes the locking of the cone handle 12. During the locking process, the position of the cone handle 12 is relatively fixed, and the positioning of the bakelite base is also completed at the same time.

[0029] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
