[0001] The utility model relates to the technical field of tray - plate limiting and fixing, and particularly relates to a tray - plate clamping device. Background Art

[0002] A tray plate generally refers to a plastic plate used in the semiconductor industry for placing semiconductor chips. The tray plate is generally flat, square and has a certain height, and can be used to hold semiconductor chips. After the staff places the semiconductor chips on the tray plate, it is necessary to stack the tray plates with chips placed on them.

[0003] During the stacking process of tray plates, in order to ensure that each tray plate can fall in the same position, it is necessary to position the tray plates. The existing positioning method is manual alignment through the edge of the tray plate. This positioning method requires workers to accurately place the tray plates on the one hand, and on the other hand, the manual placement efficiency and alignment efficiency are relatively low, and it is not suitable for large - batch placement.

Specific embodiments

[0022] The following further details the specific embodiments of the present utility model with reference to the accompanying drawings.

[0023] Provided by Figures 1 to 5 A tray clamping device includes a frame body 1, a transverse clamping mechanism and a driving mechanism arranged on the frame body 1. The transverse clamping mechanism clamps and limits the tray transversely. The driving mechanism drives the transverse clamping mechanism to approach or move away from the tray. Under the action of the transverse clamping mechanism, on the one hand, centering treatment is performed on the tray, and on the other hand, at

[0024] The transverse clamping mechanism includes a left clamping plate 2, a right clamping plate 3 and a transverse opposite movement component. The left clamping plate 2 and the right clamping plate 3 are connected by the transverse opposite movement component. A hollow frame is formed between the left clamping plate 2 and the right clamping plate 3. The tray is located inside the hollow frame formed between the left clamping plate 2 and the right clamping plate 3. The opposite movement component is used to change the distance between the left clamping plate 2 and the right clamping plate 3. The tray is located inside the hollow frame, so that the left clamping plate 2 and the right clamping plate 3 can clamp and limit the tray.

[0025] The driving mechanism includes a first cam 4 and a first tension spring 5. The circumferential surface of the first cam 4 acts on the transverse clamping mechanism. One end of the first tension spring 5 is connected to the frame body 1, and the other end of the first tension spring 5 is connected to the transverse clamping mechanism. The first cam 4 is used to push the transverse clamping mechanism, and the first tension spring 5 is used to pull the transverse clamping mechanism. Under the combined action of the first cam 4 and the first tension spring 5, the transverse clamping mechanism can move reciprocally.

[0026] The horizontal opposite movement assembly includes a gear 6, a left rack 7 and a right rack 8. The gear 6 rotates with the frame 1. The left rack 7 and the right rack 8 are located on both sides of the gear 6 and mesh with the gear 6. The left rack 7 is fixedly connected to the left clamping plate 2, and the right rack 8 is connected to the right clamping plate 3. The gear 6 is located between the left rack 7 and the right rack 8. During the movement of the left rack 7 or the right rack 8, the movement is synchronously transmitted to the right rack 8 or the left rack 7 through the gear 6, so that the left clamping plate 2 and the right clamping plate 3 can move synchronously;

[0027] At the same time, the horizontal opposite movement assembly can adopt a rod-shaped structure arranged obliquely, so that the left clamping plate 2 and the right clamping plate 3 can move relatively or away from each other synchronously.

[0028] It also includes a longitudinal clamping mechanism. The longitudinal clamping mechanism includes an upper clamping plate 9 and a lower clamping plate 10. The upper clamping plate 9 and the lower clamping plate 10 are slidably connected to the horizontal clamping mechanism. The upper clamping plate 9 and the lower clamping plate 10 are slidably connected to the horizontal clamping mechanism through sliders. Among them, the upper clamping plate 9 or the lower clamping plate 10 can be synchronously arranged on the left clamping plate 2, or can be synchronously arranged on the right clamping plate 3, or can be separately arranged on the left clamping plate 2 or the right clamping plate 3;

[0029] A longitudinal clamping space for cooperating with the hollow frame body is formed between the upper clamping plate 9 and the lower clamping plate 10. Under the action of the left clamping plate 2, the right clamping plate 3, the upper clamping plate 9 and the lower clamping plate 10, the tray can be completely surrounded and clamped and fixed.

[0030] The longitudinal clamping mechanism also includes a longitudinal opposite movement assembly. The longitudinal opposite movement assembly includes a push plate 11, a first driving surface 12 and a second driving surface 13. The push plate 11 is slidably connected to the horizontal clamping mechanism. The first driving surface 12 and the second driving surface 13 are arranged in a stepped manner and are both arranged on the upper clamping plate 9 and the lower clamping plate 10. The push plate 11 contacts the first driving surface 12 and the second driving surface 13 in sequence along the parallel direction of the longitudinal clamping mechanism. The push plate 11 pushes the first driving surface 12 and the second driving surface 13. At the same time, because the first driving surface 12 and the second driving surface 13 are arranged in a stepped manner, when the push plate 11 contacts the first driving surface 12 and the second driving surface 13 in sequence, it will cause the upper clamping plate 9 or the lower clamping plate 10 to move relatively.

[0031] The driving mechanism further includes a second cam 14 and a second tension spring 15. The second cam 14 acts on the push plate 11 to drive the push plate 11 to slide. There is a 90-degree angle between the first cam 4 and the second cam 14. One end of the second tension spring 15 is fixed to the frame 1, and the other end of the second tension spring 15 is connected to the push plate 11. The angle between the first cam 4 and the second cam 14 enables the longitudinal clamping mechanism and the transverse clamping mechanism to act separately but also simultaneously. Between the second cam 14 and the second tension spring 15 is used to enable the push plate 11 to move reciprocally.

[0032] The driving mechanism further includes a first driving roller 16 rotatably connected to the transverse mechanism and a second driving roller 17 rotatably connected to the push plate 11. The circumferential surface of the first cam 4 acts on the circumferential surface of the first driving roller 16, and the circumferential surface of the second cam 14 acts on the circumferential surface of the second driving roller 17. The first driving roller 16 and the second driving roller 17 are used to assist the first cam 4 and the second cam 14 in acting on the push plate 11, the left clamping plate 2, or the right clamping plate 3.

[0033] When the present utility model is in use, the tray is located inside the hollow frame formed between the left clamping plate 2, the right clamping plate 3, the upper clamping plate 9, and the lower clamping plate 10. When it is necessary to clamp the tray, the first cam 4 and the second cam 14 rotate synchronously. Among them, the first cam 4 first contacts the left clamping plate 2 through the first driving roller 16, and the convex part of the first cam 4 presses the left clamping plate 2, causing the left clamping plate 2 to move towards the right clamping plate 3. At the same time, under the action of the left rack 7, the gear 6, and the right rack 8, the right clamping plate 3 moves towards the left clamping plate 2, thereby clamping the tray in the left-right direction. When the first cam 4 rotates a certain angle, the second cam 14 simultaneously pushes the push plate 11. The push plate 11 squeezes the upper clamping plate 9 or the lower clamping plate 10 under the stepped action of the first driving surface 12 and the second driving surface 13, causing relative movement between the upper clamping plate 9 and the lower clamping plate 10.

[0034] The present utility model adopts the structural combination among the first cam 4, the left rack 7, the gear 6, and the right rack 8 to automatically clamp the tray in the left-right direction, and automatically center the tray in the left-right direction during the clamping process;

[0035] At the same time, under the action of the second cam 14, the push plate 11, the first driving surface 12, and the second driving surface 13, the tray is automatically clamped in the up-down direction, and the tray is automatically clamped as a whole under the action of the above structure.
