Description

Technical Field

[0002] In the automated production process of circuit boards, a clamping frame is used to clamp the circuit board. The entire clamping frame is automatically transported between various processes as a small unit and the circuit boards on it are processed for production. Usually, a robot grabs the circuit board and puts it on the clamping frame. However, when producing some circuit boards with thinner thickness, the robot cannot complete the action of grabbing the board and automatically putting it on the clamping frame. At this time, the thin circuit board is usually clamped on the clamping frame manually. Simply clamping the thin circuit board on the clamping frame manually requires manually opening the clamping frame and then putting the board on. This is not only inefficient, but also easily causes damage to the thin circuit board during the boarding process, resulting in the scrapping of the circuit board and reducing the production yield.

DETAILED DESCRIPTION

[0016] In order to better understand the purpose, structure and function of the present invention, the specific embodiment of the "an auxiliary board loading device" of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] See also Figure 1-Figure 8In this embodiment, the auxiliary boarding device includes a base 100 and an upper board platform 200 directly above the base 100; an opening and closing cylinder 101 electrically connected to the central controller is provided on the base 100, and an upper board area 201 and an insertion frame assembly 202 are provided on the upper board platform 200, and the movable end of the opening and closing cylinder 101 is hinged to the insertion frame assembly 202; the opening and closing cylinder 101 can drive the insertion frame assembly 202 to rotate to a vertical state, and then the splint frame 300 can be vertically inserted into the insertion frame assembly 202 automatically by manual or mechanical hands; then the opening and closing cylinder 101 drives the insertion frame assembly 202 to rotate to a horizontal state, driving the splint frame 300 to rotate and lay flat on the upper board area 201; a rotating and telescopic assembly electrically connected to the central controller is provided at the edge of the upper board area 201 203, when the clamping frame 300 is laid flat on the upper plate area 201, the rotating telescopic assembly 203 abuts against and presses the clamping frame 300 to prevent the clamping frame 300 from moving; a plate clamping assembly 302 is arranged on the frame 301 of the clamping frame 300, and a clamping cylinder 102 electrically connected to the central controller is arranged on the base 100, and the movable end of the clamping cylinder 102 is fixedly connected to the clamping platform 103, and a clamping piece 104 corresponding to the plate clamping assembly 302 is arranged on the clamping platform 103, and the clamping cylinder 102 drives the clamping piece 104 to move upward to abut against the plate clamping assembly 302 to open the plate clamping assembly 302 on the frame 301, or drives the clamping piece 104 to move downward away from the plate clamping assembly 302, and the plate clamping assembly 302 on the frame 301 will be automatically clamped closed.

[0018] As an illustration, the device is preferably arranged near the robot to cooperate with automated production. When the auxiliary upper plate device is used, the opening and closing cylinder 101 first causes the insertion frame assembly 202 to rotate to a vertical state, and then the robot vertically inserts the splint frame 300 into the insertion frame assembly 202, and then the opening and closing cylinder 101 controls the insertion frame assembly 202 to drive the splint frame 300 to rotate to a horizontal state, and the splint frame 300 will lie face up in the upper plate area 201, and only the rotating and telescopic assembly 203 at the edge of the upper plate area 201 begins to telescope and rotate to abut and fix the splint frame 300, preventing the splint frame from 300 moves, then the clamping cylinder 102 will tend to force the clamping piece 104 to abut the board clamping assembly 302 on the frame 301 to open the board clamp. The operator only needs to place the thin circuit board on the clamping position of the clamping frame 300, and then the central controller will perform the above operation in reverse to complete the placement of the thin circuit board on the clamping frame 300. The whole process only requires manual horizontal board placement, which is convenient and fast to operate, improves efficiency, and reduces the number of manual operation steps. The board is placed horizontally, which can prevent the board placement process from causing damage to the circuit board, thereby improving the yield of product production.

[0019] More specifically, in the present embodiment, the rotating and telescopic assembly 203 includes a rotating and telescopic cylinder 2031 electrically connected to the central controller, the movable end of the rotating and telescopic cylinder 2031 is fixedly connected to one end of the abutment claw 2032, and a flexible abutment block 2033 is provided at the bottom of the other end of the abutment claw 2032; the rotating and telescopic cylinder 2031 controls the abutment block 2033 to rotate to directly above the frame 301 of the splint frame 300, and controls the abutment block 2033 to retract to abut and press the splint frame 300.

[0020] See also Figure 1 and Figure 2 In this embodiment, the base 100 is fixedly connected to the upper plate platform 200 through the support column 105, and the four edges of the base 100 and the upper plate platform 200 are connected through the side panels 106 to form an isolation space to protect the components set on the base 100 and below the upper plate platform 200; and a control switch 107 electrically connected to the central controller is provided on the front side panel 106, and there are two control switches, so that when starting and stopping manually, both hands need to be pressed at the same time to play a protective role against accidental touch. A reset switch and an emergency stop switch electrically connected to the central controller can also be provided on the front side panel 106.

[0021] See also Figure 7 In this embodiment, a roller 108 is provided at the top of the clamping member 104. The roller 108 abuts against the plate clamping assembly 302 and rolls to open the clamp, converting the sliding friction into rolling friction, which can reduce the friction loss of the plate clamping assembly 302, increase the service life, and reduce the noise during use.

[0022] See also Figure 5 In this embodiment, a vertical oil pressure buffer 204 and a horizontal oil pressure buffer 205 are provided on the upper plate platform 200. When the insertion frame assembly 202 is rotated to a vertical state, it abuts against the vertical oil pressure buffer 204, and when the insertion frame assembly 202 is rotated to a horizontal state, it abuts against the horizontal oil pressure buffer 205. This can provide a buffering protection for the insertion frame assembly 202 when rotating vertically and horizontally, thereby increasing the service life of the equipment.

The push-up cylinder 109 drives the push-up platform 110 to move up and down to support the bottom of the circuit board; since the thin circuit board itself has insufficient supporting tension, in order to better clamp the edge of the board when placing it, the bottom of the center of the circuit board can be supported by the push-up cylinder 109, and then retracted after clamping, which can improve the board loading efficiency and board loading yield.
