[0002] An open-top packaging box is assembled by a hinge connecting a box body and a box cover. When assembling the hinge, the prior art mainly assembles the hinge manually. A hinge fixing device is fixed on an assembly table through bolts. Workers neatly arrange a plurality of hinges on the fixing device, and then the workers hold a rubber hammer and press down on the hinges one by one in sequence, so as to realize the hinge assembly. However, this method requires workers to manually place the hinges and hold the rubber hammer to press down the hinges. Multiple hinges need to be pressed one by one. This method has low assembly efficiency. When pressing down the hinges manually with a hammer, the hinges are prone to being not assembled in place, the quality is uncontrollable, which affects the production efficiency and quality stability of hinge assembly. At the same time, the hinge fixing device is fixed to the assembly table through bolts. When the hinge model changes later, it is inconvenient to perform the corresponding model switching operation on the hinge fixing device. Content of the Utility Model

[0022] It further includes a moving seat 9 which is arranged between two adjacent locking columns 7 in the longitudinal direction. Symmetrically distributed first springs 8 are provided between the moving seat 9 and the adjacent grooves 6. The first springs 8 are movably sleeved on the outer sides of the adjacent locking columns 7. The front end of the vertical moving seat 15 is slidably connected with uniformly distributed second locking columns 17. The front ends of the second locking columns 17 are respectively provided with dial plates 19. Second jacks 20 are formed in the upper ends of the combined pressing blocks 16. The second locking columns 17 are inserted into the adjacent second jacks 20. Second springs 18 are provided between the dial plates 19 and the vertical moving seat 15. The second springs 18 are movably sleeved on the outer sides of the adjacent second locking columns 17.

[0023] Among them, it further includes a single-chip microcomputer 2 which is located outside the assembly table 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply. A support frame 12 is provided on the upper side of the assembly table 1. A linear motor 14 is provided at the telescopic end of a electro-hydraulic push rod 13 on the upper side of the support frame 12. The moving end of the linear motor 14 is fixedly connected to the upper end of the vertical moving seat 15. The input ends of the linear motor 14 and the electro-hydraulic push rod 13 are both electrically connected to the output end of the single-chip microcomputer 2. Two manual switches 10 are connected in series between the circuit of the electro-hydraulic push rod 13 and the single-chip microcomputer 2.

The laser rangefinder 21 is in two-way electrical connection with the single-chip microcomputer 2.

[0024] The working principle of the present utility model is as follows:

[0025] When assembling the hinge, first, a plurality of hinges are accurately fixed and placed through the fixed base 4 and the replaceable fixture 5. Subsequently, the single-chip microcomputer 2 starts the electro-hydraulic push rod 13 so that its telescopic end indirectly drives the combined pressing block 16 to move downward, thereby enabling the combined pressing block 16 to press down on a plurality of hinges at one time, which is convenient to use and has high hinge assembly efficiency. When the electro-hydraulic push rod 13 operates, the staff needs to press two manual switches 10 simultaneously, so as to establish an electrical connection between the electro-hydraulic push rod 13 and the single-chip microcomputer 2. The single-chip microcomputer 2 starts the linear motor 14 so that its moving end drives the vertical moving seat 15 to move horizontally, thereby adjusting the downward pressing position of the combined pressing block 16. The single-chip microcomputer 2 starts the laser rangefinder 21. The laser rangefinder 21 emits a light signal that irradiates the top wall of the support frame 12 and is reflected back to the initial position. By using the propagation time and speed of the light signal, the distance between the linear motor 14 and the top wall of the support frame 12 is obtained. The laser rangefinder 21 transmits the measured result to the single-chip microcomputer 2. The single-chip microcomputer 2 adjusts the downward pressing height of the combined pressing block 16 according to the measured result and the height of the support frame 12 itself as required.

[0026] When the hinge size changes, pull the dial plate 19 to drive the first locking post 7 to move towards one end away from the center of the device, thereby releasing the plug-in fixation of the first locking post 7 to the first jack 11. The first spring 8 is elastically stretched. Then, drive the fixed base 4 with the replaceable fixture 5 to move upward along the first slot 3 and take it out. And install and fix the fixed base 4 and the replaceable fixture 5 corresponding to the hinge size model quickly through the same principle. Through the stretching elastic force of the first spring 8, relative sliding and separation between the first locking post 7 and the adjacent first jack 11 during the plug-in process are avoided. At the same time, pull the dial plate 19 to drive the second locking post 17 away from the adjacent second jack 20, release the vertical movement limit between the combined pressure block 16 and the second slot, stretch the second spring 18, then take out the combined pressure block 16, and install and fix the replaced combined pressure block 16 corresponding to the hinge size model through the same principle. Through the stretching elastic force of the second spring 18, the second locking post 17 is plugged and locked with the adjacent second jack 20. The device can quickly replace the fixed base 4, the replaceable fixture 5 and the combined pressure block 16 according to the change of the hinge's own size model, which is convenient to use and has a wide range of applicability.

[0027] It should be noted that, in the above embodiments, the single-chip microcomputer 2 can adopt MSP430, the electro-hydraulic push rod 13 can adopt DYTZ-1000, the linear motor 14 can adopt GD magnetic axis micro linear motor, the laser rangefinder 21 can adopt WH-LRF laser rangefinder, and the single-chip microcomputer 2 controls the electro-hydraulic push rod 13, the linear motor 14 and the laser rangefinder 21 to work using the commonly used methods in the prior art.
