DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5The utility model is an automatic bending device for PC boards, comprising an operating table 1 and a supporting table 2. Four positioning rods 14 are evenly arranged at the four corners of the operating table 1. The four positioning rods 14 are correspondingly connected to the four corners of the bending plate 4. The positioning rods 4 can control the accuracy of the up and down movement of the bending plate 4. The front and rear ends of the operating table 1 are connected with a limit block 13. The limit blocks 13 arranged at the front and rear ends of the operating table 1 are used to position the PC board so that the PC board can be accurately transported out after bending.

[0025] The utility model: the operating platform 1 and the supporting platform 2 are connected vertically up and down. The outer top of the operating platform 1 is equipped with two first brake cylinders 3, the action ends of the two first brake cylinders 3 pass through the top of the operating platform 1, and the action ends are arranged inside the operating platform 1. The action ends of the two first brake cylinders 3 are connected to a bending plate 4, which makes it easier to accurately control the shape and size of the PC board, so that higher accuracy and repeatability can be achieved, and it is not affected by the thickness difference of the PC board. Two sliding bars 12 are laterally connected to the inner bottom of the operating table 1, and the outer ends of the two sliding bars 12 are slidably connected to a movable plate 5, and the movable plate 5 is provided with a first clamping plate 6 for clamping the PC board; the inner ends of the two sliding bars 12 are fixed with a fixed plate 8, and the fixed plate 8 is provided with a second clamping plate 9 for clamping the PC board. The first clamping plate 6 and the second clamping plate 9 are arranged in a counterposition manner. The two clamping plates have the advantages of firm fixation and high precision, and can also effectively insulate and prevent the PC board from generating static electricity to interfere with the intelligent bending operation, thereby avoiding data deviation in the operation.

[0026] On the one hand, the staff places the PC board to be processed between the movable plate 5 and the fixed plate 8, wherein the movable plate 5 is connected to two second brake cylinders 7, and the two second brake cylinders 7 are assembled on the inner side of the operating table 1. The two second brake cylinders 7 are electrically connected to two controllers 10 respectively. The two second brake cylinders 7 are started by the two controllers 10 to drive the movable plate 5 to move close to the fixed plate 8, so as to clamp and position the PC board. Then, the bending parameters are set by the controller 1, and the set parameters include DWELL time, height, position and material bending angle, etc. After completing all the data, the two first brake cylinders 3 are started to control the bending plate 4 to move downward. When the lower surface contacts the PC board, pressure is applied to it to perform the bending operation. After the bending operation in the set data is completed, the bent PC board is exported through the discharge plate 11, and the bent PC board is measured by the bending angle detector. If the detected size meets the standard, it can be discharged.

[0027] On the other hand, if the inspection size fails to meet the standard due to setting errors, the two second brake cylinders 7 connected by the mobile plate 5 will continue to push the mobile plate 5 to dock with the fixed plate 8. After a plane is formed between the two, the PC board that has just been bent and does not meet the standard is placed flat on the mobile plate 5 and the fixed plate 8, and the two first brake cylinders 3 are started to control the bending plate 4 to move downward to restore the bending part of the PC board that does not meet the standard after the bending process to a flat state. After taking it out, repeat the bending process until it is qualified. Reworking the PC board after bending errors helps to reduce the scrap rate of PC boards and reduce total costs.

[0028] The two controllers 10 are symmetrically arranged at the front of the operating table 1 so that the staff can operate with both hands to maintain balanced bending and improve bending accuracy.

[0029] A discharge plate 11 is disposed between the two controllers 10 , and the discharge plate 11 is connected to the fixed plate 8 in sequence. The PC board after the bending process is recovered by the provided discharge plate 11 , so that the processing flow is smooth.

[0030] The operating table 1 is composed of three side baffles and two upper and lower horizontal plates. The three side baffles are connected in sequence between the upper and lower horizontal plates, which is convenient for disassembly, assembly and replacement. The matching plates of appropriate sizes can be selected according to actual conditions, and the operating table has strong versatility.

[0031] The support platform 2 is composed of two upper and lower planar plates and four connecting columns. The four connecting columns are sequentially connected between the upper and lower planar plates, which is convenient for disassembly, assembly and replacement. The supporting plate of suitable size can also be selected according to actual conditions, and it has strong versatility.

[0032] A power supply box 16 is provided at the inner bottom of the support platform 2. The power supply box 16 is electrically connected to a voltage stabilizer 15. The power supply box 16 continuously provides power for driving the cylinder.

[0033] Support legs 18 are connected to the four corners of the support platform 2. Universal wheels 17 are arranged on the inner side of each support leg 18. Each universal wheel 17 adopts a foldable structure and is connected to the bottom of the support platform 2, so as to facilitate switching between the moving state and the positioning state of the support platform 2.

The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
