Abstract
Description
Technical Field
[0001] The utility model relates to a vacuum hole plugging machine for a PCB board, in particular to an automatic sealing door. Background Art
[0002] The PCB vacuum plugging machine needs to be configured with a vacuum environment. In order to facilitate the entry and exit of workpieces and close the machine door, an automatically controllable sealing door must be set for the PCB vacuum plugging machine. The existing sealing doors include two types: double-action closing structure and flip-type closing. Among them, the sealing door with a double-action closing structure has the problem of more components and complex control logic, while the flip-type closing structure requires more horizontal space, which is not conducive to the connection and matching of related mechanisms. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide an automatic sealing door with simple structure, space saving and simple control logic in view of the deficiencies of the prior art.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.
[0005] An automatic sealing door comprises a door body and a driving assembly arranged at both ends of the door body, the driving assembly comprises a bracket, a guide seat and a cylinder, the cylinder is vertically fixed on the bracket, and the driving end of the cylinder is transmission-connected to the door body, the bracket and the guide seat are both fixed on a preset frame, at least one guide groove is provided on the guide seat, the guide groove comprises a vertical groove and an oblique groove located at the upper end of the vertical groove, guide blocks corresponding to the guide seats are respectively fixed at both ends of the door body, the guide blocks are provided with guide wheels, the guide wheels are arranged in the guide groove and the two are rollingly matched.
[0006] Preferably, the guide seat is provided with two upper and lower guide grooves, and the guide block is provided with two upper and lower guide wheels.
[0007] Preferably, the bracket is an L-shaped bracket, a slot is formed on a side of the guide seat facing away from the door body, and the upper end of the bracket is clamped in the slot.
[0008] Preferably, the bracket and the guide seat are fixedly connected by screws.
[0009] Preferably, the cylinder is a pen-shaped cylinder.
[0010] Preferably, U-shaped supports are fixed to positions near both ends of the door body respectively, a hinged joint is hinged inside the U-shaped support, and the driving end of the cylinder is fixedly connected to the hinged joint.
[0011] In the automatic sealing door disclosed by the utility model, the driving assembly is used to drive the door body to move upward for a certain stroke and then flip obliquely, thereby opening the machine door. Specifically, two left-right symmetrical cylinders are used to simultaneously drive the two ends of the door body to rise, and at the same time, the guide wheel rolls upward along the vertical groove. When the guide wheel rolls into the oblique groove, it can drive the door body to flip obliquely, thereby realizing the door opening action. When the sealing door needs to be closed, it is only necessary to control the downward movement of the cylinder. The control logic of the whole process is simple and the reliability is better. At the same time, the utility model only needs one door body and the overall structure is simple. It can effectively save horizontal space and can be more reasonably matched with adjacent mechanisms to avoid mutual position interference. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 3 Decomposition of drive components Figure 2 . DETAILED DESCRIPTION
[0015] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0016] The utility model discloses an automatic sealing door, combined with Figures 1 to 3 As shown, it includes a door body 1 and a driving assembly 2 which is arranged at both ends of the door body 1, the driving assembly 2 includes a bracket 20, a guide seat 21 and a cylinder 22, the cylinder 22 is vertically fixed on the bracket 20, and the driving end of the cylinder 22 is transmission-connected to the door body 1, the bracket 20 and the guide seat 21 are both fixed on a preset frame, at least one guide groove 23 is provided on the guide seat 21, the guide groove 23 includes a vertical groove 230 and an oblique groove 231 located at the upper end of the vertical groove 230, guide blocks 10 corresponding to the guide seat 21 are respectively fixed at both ends of the door body 1, the guide block 10 is provided with a guide wheel 11, the guide wheel 11 is arranged in the guide groove 23 and the two are rollingly matched.
[0017] In the above structure, the driving assembly 2 is used to drive the door body 1 to move upward for a certain stroke and then flip obliquely, so as to open the machine door. Specifically, two left-right symmetrical cylinders 22 are used to simultaneously drive the two ends of the door body 1 to rise. At the same time, the guide wheel 11 rolls upward along the vertical groove 230. When the guide wheel 11 rolls into the oblique groove 231, it can drive the door body 1 to flip obliquely, so as to realize the door opening action. When the sealing door needs to be closed, it is only necessary to control the downward movement of the cylinder 22. The control logic of the whole process is simple and the reliability is better. At the same time, the utility model only needs one door body, and the overall structure is simple, which can effectively save horizontal space and can be more reasonably matched with adjacent mechanisms to avoid mutual position interference.
[0018] In order to ensure that the door body 1 is lifted and lowered smoothly, the present embodiment preferably provides two sets of guide grooves 23 and guide wheel 11 matching mechanisms, see Figure 2 and Figure 3 The guide seat 21 is provided with two upper and lower guide grooves 23, and the guide block 10 is provided with two upper and lower guide wheels 11.
