DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The present invention provides Figures 1 to 5 The multi-directional and multi-type automatic clamping process shown includes the following steps:

[0031] S1. Installing clips in the upper clamping mechanism 2 and the lower clamping mechanism 3;

[0032] S2, separate the upper clamping mechanism 2 and the lower clamping mechanism 3 through the lifting mechanism 1;

[0033] S3, placing the product to be pressed into the mold cavity of the lower clamping mechanism 3;

[0034] S4. The upper clamping mechanism 2 is driven downward by the lifting mechanism 1 so that the upper clamping mechanism 2 contacts the product to be pressed and installs the clamp into the product. At the same time, the lower clamping mechanism 3 installs the clamp into the product.

[0035] S5. Install the clip into the side clamping mechanism 4, and move the side clamping mechanism 4 to install the clip to the side position of the product;

[0036] S6. After the clamping work is completed, the upper clamping mechanism 2 is moved up and restored to the original position, and the side clamping mechanism 4 returns to the original position, and then enters step S1 to perform a cyclic operation.

[0037] In step S1, the upper clamping mechanism 2 includes an upper slide plate 21, an upper template 22 is installed on the lower surface of the upper slide plate 21, an upper positioning plate 23 is installed on the lower surface of the upper template 22, an upper floating plate 24 is installed on the lower surface of the upper positioning plate 23, an upper buffer mechanism 25 is provided between the upper floating plate 24 and the upper positioning plate 23, an upper pre-pressing plate 26 is installed on the lower surface of the upper floating plate 24, an upper clamping mechanism 27 is installed on the lower surface of the upper positioning plate 23, and an upper through hole is provided on the surface of the upper floating plate 24 at a position corresponding to the upper clamping mechanism 27. The upper floating plate 24 is driven downward by the cooperation of the upper slide plate 21 and the upper positioning plate 23. When the upper positioning plate 23 moves downward, it can provide compression to the upper buffer mechanism 25. The upper pre-pressing plate 26 on the upper floating plate 24 is driven by the upper buffer mechanism 25 to pre-fix the product to be pressed. Then, the upper positioning plate 23 drives the upper clamping mechanism 27 to move downward to press the product to be pressed.

[0038] An upper mold cavity 271 is provided at the bottom end of the upper clamping mechanism 27 , in which a clip is placed. The clip to be used on the product can be assembled into the upper mold cavity 271 through the upper mold cavity 271 , making it convenient to press the product.

[0039] When the cam 33 is unlocked, the cam 33 is unlocked and the lock 32 is unlocked, so that the cam 33 can be unlocked and the lock 32 can be unlocked.

[0040] A lower mold cavity 321 is provided at the upper end of the lower clamping mechanism 32. A clip is placed in the lower mold cavity 321 in the same manner as in the upper mold cavity 271. The clip to be used on the product can be assembled into the lower mold cavity 321 through the setting of the lower mold cavity 321, thereby providing support and pressing effect for the lower end of the product.

[0041] In step S2, the lifting mechanism 1 includes a frame 101, an upper plate 102 is installed on the top of the frame 101, and a push rod cylinder 103 is installed at the center of the surface of the upper plate 102. The piston rod of the push rod cylinder 103 is fixedly connected to the upper surface of the upper slide 21. By setting up the frame 101, the upper clamping mechanism 2 and the lower clamping mechanism 3 can be conveniently installed separately up and down, and the push rod cylinder 103 provides a driving force to drive the upper clamping mechanism 2 to move up and down, thereby facilitating the placement and pressing process of the product.

[0042] The inner side of the frame 101 is fixedly connected with a positioning rod 5, and the surface of the positioning rod 5 is slidably connected with a sliding sleeve 6, which is embedded in the four sides of the upper slide 21. The positioning rod 5 is provided to enhance the limiting effect on the moving position of the upper clamping mechanism 2 installed on the upper slide 21, thereby enhancing the stability of the upper clamping mechanism 2.

[0043] The upper pre-pressing plate 26 is positioned at the outer end of the lower pre-pressing plate 35, and the upper clamping mechanism 27 and the lower clamping mechanism 32 are positioned relative to the side clamping mechanism 4, which can facilitate the upper pre-pressing plate 26 and the lower pre-pressing plate 35 to pre-position the product up and down.

[0044] In step S5, the side clamping mechanism 4 includes a driving seat 41, which is installed at the edge of the side of the lower fixed plate 31. A side clamping plate 42 is installed on the driving seat 41. A slot 43 is provided on the surface of the lower floating plate 34 at a position corresponding to the side clamping plate 42. The top of the side clamping plate 42 passes through the slot 43 and extends upward to contact the side part of the product to be pressed. The side clamping mechanism 4 set on the lower fixed plate 31 can position the side direction of the product, and the side clamping plate 42 is driven forward by the set driving seat 41, so that the side clamping plate 42 is moved in the slot 43 and fits in the side direction of the product.

[0045] The aperture of the card slot 43 is set to be rectangular, and the length range of the card slot 43 is set between 6cm and 10cm, in order to facilitate the movement of the side clamping plate 42, so that the side clamping plate 42 can achieve a lateral clamping effect on the product.

[0046] During specific use, the upper clamping mechanism 2 is first driven by the push rod cylinder 103 to move along the direction of the positioning rod 5, and then the upper clamping mechanism 2 and the lower clamping mechanism 3 are separated, thereby separating the upper mold cavity 271 and the lower mold cavity 321, and then the clamps that need to be clamped in each direction are installed in each mold cavity, and then the products to be pressed are placed in place, and then the pushed rod cylinder 103 that is started drives the upper clamping mechanism 2 to move downward. In the process of the upper clamping mechanism 2 moving downward, the cooperation of the upper slide plate 21 and the upper positioning plate 23 can drive the upper floating plate 24 to move downward. While the upper positioning plate 23 moves downward, it can provide compression to the upper buffer mechanism 25, thereby driving the upper pre-compression plate 26 on the upper floating plate 24 to pre-fix the product to be pressed through the upper buffer mechanism 25, and then the upper positioning plate 23 drives the upper clamping mechanism 27 to move downward. The product to be pressed is pressed down. Similarly, the lower clamping mechanism 3 can provide support and buffering for the lower floating plate 34 through the lower fixed plate 31 and the lower buffer mechanism 33, so that the lower floating plate 34 drives the lower pre-pressing plate 35 to pre-position the product, and then the lower end of the product is supported and clamped by the lower clamping mechanism 32 installed on the lower fixed plate 31, thereby cooperating with the upper clamping mechanism 2, so that the upper and lower positions of the upper clamping mechanism 2 and the lower clamping mechanism 3 correspond to each other. When the positions of the upper clamping mechanism 2 and the lower clamping mechanism 3 correspond to each other, the side clamping mechanism 4 set on the lower fixed plate 31 can then position the side direction of the product to complete the clamping work. After the clamping work is completed, the upper clamping mechanism 2 is moved up and restored to its original position, and the side clamping mechanism 4 returns to the original position, and the operation is cyclically performed.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
