Description

Technical Field

[0001] The present invention relates to automatic production equipment for circuit boards, and particularly to an auxiliary board loading device. Background Art

[0002] In the automatic production process of circuit boards, a clamping frame is used to hold the circuit board, and the entire clamping frame is automatically transported between various processes as a small unit and the circuit board thereon is processed; usually, a manipulator grabs the circuit board and loads it onto the clamping frame. However, when producing some circuit boards with a smaller thickness, the manipulator cannot complete the action of grabbing the board and automatically loading it onto the clamping frame. At this time, the thin circuit board is usually manually clamped onto the clamping frame. Simply manually clamping the thin circuit board onto the clamping frame requires manually opening the clamping frame and then loading the board. This not only has low efficiency, but also easily damages the thin circuit board during the loading process, resulting in circuit board scrapping and reducing the production yield.

[0029] In order to better understand the purpose, structure and function of the present invention, the following further describes in detail specific embodiments of the "auxiliary upper plate device" of the present invention with reference to the accompanying drawings.

[0030] See Figures 1 - 8, in this embodiment, the auxiliary upper plate device includes a base 100 and an upper plate 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 plate area 201 and a plug-in frame assembly 202 are provided on the upper plate platform 200. The movable end of the opening and closing cylinder 101 is hinged to the plug-in frame assembly 202; the opening and closing cylinder 101 can drive the plug-in frame assembly 202 to rotate to a vertical state, and then the clamping plate frame 300 can be vertically inserted into the plug-in frame assembly 202 manually or automatically by a manipulator; then the opening and closing cylinder 101 drives the plug-in frame assembly 202 to rotate to a horizontal state, driving the clamping plate frame 300 to rotate and flatten onto the upper plate area 201; a rotary telescopic assembly 203 electrically connected to the central controller is provided at the edge position of the upper plate area 201. When the clamping plate frame 300 is flattened onto the upper plate area 201, the rotary telescopic assembly 203 abuts and presses the clamping plate frame 300 to prevent the clamping plate frame 300 from moving; clamping plate assemblies 302 are provided on the frame 301 of the clamping plate frame 300, and an opening clamp cylinder 102 electrically connected to the central controller is provided on the base 100. The movable end of the opening clamp cylinder 102 is fixedly connected with an opening clamp platform 103, and an opening clamp member 104 corresponding to the clamping plate assembly 302 is provided on the opening clamp platform 103. The opening clamp cylinder 102 drives the opening clamp member 104 to move upward to abut against the clamping plate assembly 302 to open the clamping plate assembly 302 on the frame 301, or drives the opening clamp member 104 to move downward away from the clamping plate assembly 302, and the clamping plate assemblies 302 on the frame 301 will automatically clamp and close.

[0031] As an illustration, this device is preferably arranged near the manipulator to cooperate with automated production. When using this auxiliary upper plate device, the opening and closing cylinder 101 first drives the plug-in frame assembly 202 to rotate to a vertical state, and then the manipulator vertically inserts the clamping plate frame 300 into the plug-in frame assembly 202. Then the opening and closing cylinder 101 controls the plug-in frame assembly 202 to drive the clamping plate frame 300 to rotate to a horizontal state. The clamping plate frame 300 lies flat face up in the upper plate area 201. Only the rotary telescopic assembly 203 at the edge of the upper plate area 201 starts to expand and rotate to abut and fix the clamping plate frame 300 to prevent the clamping plate frame 300 from moving. Then the opening clamp cylinder 102 will drive the opening clamp member 104 to abut against the clamping plate assembly 302 on the frame 301 to open the clamp. At this time, the operator only needs to place the thin circuit board at the clamping position of the clamping plate frame 300. Then, through the central controller, the above operations are executed in reverse to complete placing the thin circuit board on the clamping plate frame 300; during the whole process, only manual horizontal upper plate is required, which is convenient and fast, improves efficiency, and reduces the number of manual operation steps. Moreover, since it is horizontal plate placement, it can prevent damage to the circuit board during the upper plate process and improve the yield of product production.

[0032] More specifically, in this embodiment, the rotary telescopic assembly 203 includes a rotary telescopic cylinder 2031 electrically connected to the central controller. The movable end of the rotary telescopic cylinder 2031 is fixedly connected to one end of the abutting claw 2032. A flexible abutting block 2033 is provided at the bottom of the other end of the abutting claw 2032. The rotary telescopic cylinder 2031 controls the abutting block 2033 to rotate to directly above the frame 301 of the clamping plate frame 300, and controls the abutting block 2033 to retract to abut and press the clamping plate frame 300 tightly.

[0033] Further refer to 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 peripheral edges of the base 100 and the upper plate platform 200 are connected by side plates 106 to form an isolation space to protect the components arranged 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 plate 106. There are two control switches. In this way, when starting or stopping manually, both hands need to be pressed simultaneously, which plays a role in protecting against accidental touch. And a reset switch and an emergency stop switch electrically connected to the central controller can also be provided on the front side plate 106.

[0034] Further refer to 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, changing the sliding friction into rolling friction, which can reduce the frictional loss of the plate clamping assembly 302, improve the service life, and can also reduce the noise during use.

[0035] Further refer to Figure 5 In this embodiment, a vertical hydraulic buffer 204 and a horizontal hydraulic buffer 205 are provided on the upper plate platform 200. When the insertion frame assembly 202 rotates to the vertical state, it abuts against the vertical hydraulic buffer 204. When the insertion frame assembly 202 rotates to the horizontal state, it abuts against the horizontal hydraulic buffer 205, which can play a buffering and protecting role for the insertion frame assembly 202 when rotating vertically and horizontally, and improve the service life of the equipment.

[0036] More specifically, in this embodiment, a limiting member 206 is further provided at the edge position of the upper plate area 201. A guiding inclined surface 207 facing the upper plate area 201 is provided on the limiting member 206 to guide the clamping plate frame 300 to be aligned into the upper plate area 201 when it rotates and lies flat. A limiting cylinder 208 electrically connected to the central controller is also provided on the upper plate platform 200. An abutting angle member 209 is fixedly connected to the movable end of the limiting cylinder 208. The limiting cylinder 208 controls the telescopic movement of the abutting angle member 209 to abut against the angle of the clamping plate frame 300 to prevent the clamping plate frame 300 on the insertion frame assembly 202 from loosening.

[0037] Further refer toFigure 6 , in this embodiment, a pushing cylinder 109 electrically connected to the central controller is further provided on the base 100. A pushing platform 110 is fixedly connected to the movable end of the pushing cylinder 109. The pushing platform 110 is located within the upper plate area 201. The pushing cylinder 109 drives the pushing platform 110 to move up and down to support the bottom of the circuit board. Since the thin circuit board has insufficient self-supporting tension, in order to better clamp the board edge during placement, the pushing cylinder 109 can support the bottom of the center of the circuit board and then retract after clamping, which can improve the upper plate efficiency and the upper plate yield.

[0038] Further refer to Figure 3 and Figure 4 , in this embodiment, a sliding frame bar 303 is further provided on the clamping plate frame 300. A positioning hole 304 and a plate clamping assembly 302 are provided on the sliding frame bar 303. Sliding grooves 3011 are provided on the frame edges 301 on both the left and right sides of the clamping plate frame 300. Fixed racks 3012 are provided on the sides of the sliding grooves 3011. Both ends of the sliding frame bar 303 slide along the sliding grooves 3011 through sliding members 305 to adjust the distance between the sliding frame bar 303 and the parallel frame edge 301, so as to adjust the size of the clamping plate area to clamp circuit boards of different sizes. A locking member 306 sliding along the sliding member 305 is sleeved on the sliding member 305. A moving rack 307 is provided at the front end of the locking member 306. An elastic member 308 and an unlocking inclined surface 309 are provided on the locking member 306. The elastic member 308 has a tendency to drive the locking member 306 to slide and abut against the sliding groove 3011, so that the moving rack 307 meshes with the fixed rack 3012 to lock the sliding frame bar 303. Abutting against the unlocking inclined surface 309 can drive the locking member 306 to slide away from the sliding groove 3011, so that the moving rack 307 is separated from the fixed rack 3012 to unlock the sliding frame bar 303.

[0039] Refer to again Figure 6 and Figure 8, in this embodiment, a slide module 111 electrically connected to the central controller is further provided on the base 100. An unlocking cylinder 113 is provided on the slide 112 of the slide module 111. A positioning head 114 and an unlocking head 115 are provided at the movable end of the unlocking cylinder 113. The unlocking cylinder 113 drives the positioning head 114 to penetrate into the positioning hole 304 on the sliding frame bar 303 to position the sliding frame bar 303. The unlocking cylinder 113 drives the unlocking head 115 to abut against the unlocking inclined surface 309 to unlock the sliding frame bar 303. Then, the slide module 111 drives the slide 112 to slide, thereby driving the unlocked sliding frame bar 303 to slide along the chute 3011, completing the automated operation of adjusting the size of the clamping plate area of the clamping plate frame 300. And a clamping cylinder 102 is also provided on the slide 112 of the slide module 111. A clamping platform 103 is fixedly connected to the movable end of the clamping cylinder 102. A clamping member 104 corresponding to the plate clamping assembly 302 on the sliding frame bar 303 is provided on the clamping platform 103. A roller 108 is also provided at the top of the clamping member 104 to open the plate clamping assembly 302 on the sliding frame bar 303.

[0040] Moreover, in this embodiment, a laser sensor and a position sensor electrically connected to the central controller are provided on the slide module 111. Through the signals fed back by the laser sensor and the position sensor, the central controller can control the slide 112 to move directly below the sliding frame bar 303 to ensure the accuracy of the process of automatically adjusting the size of the clamping plate area.
