[0027] Specifically, the electromagnetic relay 5 is placed in the shell 41, the force transmission assembly 6 pushes the push rod 43, the push rod 43 drives the clamping part 42 to move, so that the two clamping parts 42 move towards each other to clamp and fix the electromagnetic relay 5, the spring 44 is arranged to drive the push rod 43 to reset, and then drive the two clamping parts 42 to reset, so as to release the fixation of the electromagnetic relay 5.

[0028] The clamping part 42 has two inclined clamping arms 421 and a connecting block 422 between the two clamping arms 421 and used for connecting the two clamping arms 421. The clamping arm 421 linearly fits the vertical edge of the electromagnetic relay 5 and pushes the electromagnetic relay 5 to rotate around its center of gravity and to be adjusted to a preset posture.

[0029] The two clamping arms 421 are symmetrically arranged on the two sides of the connecting block 422 with the vertical center line of the front face of the connecting block 422 as the axis of symmetry. The angle between the clamping arm 421 and the front face of the connecting block 422 is obtuse. By arranging the two outwardly inclined clamping arms 421, when the two clamping parts 42 move towards each other, the four clamping arms 421 successively fit the four vertical edges of the electromagnetic relay 5 in the shape of a rectangular block and then push the electromagnetic relay 5 to rotate around its center of gravity, until the four clamping arms 421 are in close contact with the four vertical edges. At this time, the electromagnetic relay 5 is adjusted to a preset posture.

[0030] The opposite faces of the two clamping arms 421 are coated with a coating layer 423. The material of the coating layer 423 is polytetrafluoroethylene. By arranging the coating layer 423, the friction between the vertical edges of the electromagnetic relay 5 and the clamping arms 421 is reduced, so as to prevent scratches.

The two sides of the force transmission plate 61 are provided with inclined guide plates 62 extending outward. By arranging the guide plates 62, the end of the push rod 43 is conveniently transitioned along the guide plates 62 to the force transmission plate 61. One end of the push rod 43 is pressed by the force transmission plate 61, so that the push rod 43 drives the two clamping parts 42 to move towards each other.

[0033] The inner wall of the groove is provided with a sliding groove 7, the inner wall of the sliding groove 7 is rotatably connected with two sliding blocks 8 respectively, the top end of the sliding block 8 is rotatably connected with one end of the guide plate 62 away from the force transmission plate 61, the inner wall of the sliding groove 7 is provided with a threaded hole penetrating through the seat body 1, the inner wall of the threaded hole is threadedly connected with a screw rod 9, one end of the screw rod 9 is rotatably connected with the force transmission plate 61, the other end of the screw rod 9 is fixedly connected with a hand wheel 10, the screw rod 9 is driven to rotate by rotating the hand wheel 10, and then the one end of the screw rod 9 generates displacement along the axis direction of the screw rod 9, and then the force transmission plate 61 is driven to move, the advancing distance of the force transmission plate 61 to the push rod 43 is adjusted to adapt to electromagnetic relays 5 of different sizes.

[0034] The one end of the push rod 43 away from the clamping part 42 is fixedly connected with a fixed seat 47, the inner wall of the fixed seat 47 is rotatably connected with a roller 46, one end of the spring 44 is fixedly connected with the shell 41, the other end of the spring 44 is fixedly connected with the fixed seat 47, the stability of the push rod 43 when it transitions to the position of the force transmission plate 61 is improved by arranging the roller 46.

[0035] Working principle: when the laser marking device of the electronic product is used, the user first adjusts the position of the force transmission plate 61, the specific method is: first, place the electromagnetic relay 5 in one of the shells 41, then start the conveying assembly 3, so that the shell 41 carrying the electromagnetic relay 5 moves to the position corresponding to the force transmission plate 61, then rotate the hand wheel 10, the hand wheel 10 drives the screw rod 9 to rotate, so that the one end of the screw rod 9 generates displacement along the axis direction of the screw rod 9, the screw rod 9 drives the force transmission plate 61 to move towards the roller 46, when the force transmission plate 61 contacts the roller 46, the transmission plate drives the roller 46 and the push rod 43 to move, the push rod 43 drives the clamping part 42 to move to clamp and fix the electromagnetic relay 5 and align it, at this time, the rotation of the hand wheel 10 is stopped, and the self-locking of the screw rod 9 is realized to keep the force transmission plate 61 at the position;

[0036] The second step is laser marking, starting the conveying assembly 3 and the laser marking assembly 2, and then placing the electromagnetic relay 5 in the shell 41, the conveying assembly 3 drives the electromagnetic relay to the bottom of the laser marking assembly 2, at this time, the conveying assembly 3 stops, and the laser marking assembly 2 marks the electromagnetic relay 5. In this process, the roller 46 first contacts the guide plate 62, the guide plate 62 extrudes the roller 46, so that the roller 46 transitions along the guide plate 62 to the force transmission plate 61, the force transmission plate 61 extrudes one end of the push rod 43, so that the push rod 43 pushes the two clamping parts 42 to generate opposite displacement, the four clamping arms 421 are in turn fitted with the four vertical edges of the rectangular block-shaped electromagnetic relay 5 and then push the electromagnetic relay 5 to rotate around its center of gravity, until the four clamping arms 421 are tightly fitted with the four vertical edges, the electromagnetic relay 5 is adjusted to the preset posture to maintain the consistency of marking. After marking is completed, the conveying assembly 3 is started again, so that the placing unit 4 moves, until the roller 46 is separated from the force transmission plate 61, the spring 44 is reset to drive the fixed seat 47 to move away from the placing unit 4, the fixed seat 47 drives the push rod 43, the push rod 43 drives the clamping part 42 to reset, so as to facilitate the user to take down the electromagnetic relay 5. In this way, the electromagnetic relay 5 is marked in batches. Compared with the prior art which needs to manually pull the pull plate, the automatic clamping and releasing of the electromagnetic relay 5 are realized through the cooperation of the force transmission assembly 6, the push rod 43 and the spring 44, and the production efficiency is improved.
