Description

Technical Field

[0001] The utility model relates to the technical field of plug-in machines, in particular to a gusset plate mechanism for a plug-in machine. Background Art

[0002] With the rapid development of electronic technology, the use of electronic products is becoming more and more widespread. PCB circuit boards are an important carrier of electronic products. Insertion machines are processing equipment that inserts various electronic components into designated positions on PCB circuit boards. During the insertion machine processing, the electronic components are generally first transported to the top of the PCB board by a clamping device for positioning. The clamping device then moves down and accurately inserts the electronic components into the preset pin sockets on the PCB circuit board. The clamping device then resets to facilitate the clamping of new electronic components for the next insertion process. The already inserted electronic components remain on the PCB circuit board and move with the PCB circuit board to the next position for welding and reinforcement operations.

[0003] In order to improve the insertion quality of electronic components, it is necessary to transport the PCB circuit board to the set position of the insertion machine and fix the PCB circuit board for accurate insertion. The conventional fixing method is that the positioning pins slide on the PCB circuit board during the movement of the PCB circuit board. When the PCB circuit board moves to the set position, the positioning pins are just embedded in the positioning holes of the PCB circuit board. Since the positioning pins slide on the PCB circuit board, it is easy to cause damage to the PCB circuit board, which greatly affects the processing quality of the PCB circuit board and has obvious defects. Therefore, a new type of clip plate mechanism for the insertion machine is urgently needed. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0025] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0026] Example 1:

[0027] Combine Figure 1-5 As shown, this embodiment provides a pinch plate mechanism for an inserter, including: a main body mechanism 100 and an adjustment mechanism 200.

[0028] Among them, the main mechanism 100 includes side panels 110 symmetrically arranged on both sides, a conveyor belt 120 installed on the side panels 110, a lifting member 130 fixed at the top of the side panel 110, a base 140 fixed at the bottom of the lifting member 130, a movable seat 160 symmetrically and slidingly arranged at the bottom of the base 140, a first adjusting rod 150 rotatably installed in the inner cavity of the base 140 and passing through the movable seat 160, a positioning cylinder 170 slidingly arranged on the movable seat 160, a collision sensor 180 fixed on the inner top wall of the positioning cylinder 170, and a positioning rod 190 movably arranged in the inner cavity of the positioning cylinder 170 and extending downward from the positioning cylinder 170.

[0029] The side panel 110 is used to install the conveyor belt 120 to ensure the stability of the conveyor belt 120. The conveyor belt 120 is used to transport PCB boards and move the PCB boards to the bottom of the plug-in machine. The lifting member 130 is used to install the base 140 and drive the base 140 to move up and down. It includes a gantry 131 fixed to the top of the side panel 110 and an electric telescopic rod 132 symmetrically installed on the gantry 131. The gantry 131 is used to fix the electric telescopic rod 132. The electric telescopic rod 132 is used to install the base 140 and drive the base 140 to move up and down.

[0030] The base 140 is used to install the movable seat 160. A groove 141 is opened at the bottom end of the base 140. The first adjusting rod 150 includes a first threaded rod 151 rotatably installed on the inner wall of the groove 141 and a first knob 152 provided on one side of the base 140 and fixedly connected to the first threaded rod 151 at its end. The threads on the first threaded rod 151 are symmetrically arranged. At the same time, the movable seat 160 includes a first threaded sleeve 162 slidingly engaged in the groove 141 and a U-shaped frame 161 fixed at the bottom end of the first threaded sleeve 162. The first threaded rod 151 passes through the first threaded sleeve 162, and the first threaded rod 151 and the first threaded sleeve 162 are engaged with each other, so that when the first knob 152 rotates, it drives the first threaded rod 151 to rotate. The rotation of the first threaded rod 151 drives the first threaded sleeves 162 on both sides to move toward each other, that is, drives the U-shaped frames 161 on both sides to move toward each other, thereby adjusting the distance between the relative positioning rods 190.

[0031] The U-shaped frame 161 is used to install the positioning cylinder 170. The positioning cylinder 170 includes a support 171 slidably set on the U-shaped frame 161 and a cylinder 172 fixed to the top of the support 171. Slide grooves 1611 are opened on the opposite inner side surfaces of the U-shaped frame 161, and slide bars 1711 are fixed on both sides of the support 171. The slide bars 1711 are slidably engaged in the slide grooves 1611 to ensure the stability of the support 171 when moving on the U-shaped frame 161. The cylinder 172 is used to install the collision sensor 180 and the positioning rod 190, and to limit the movement of the positioning rod 190.

[0032] The positioning rod 190 is used to be inserted into the positioning hole on the PCB board to position the PCB board. The positioning rod 190 includes a T-shaped rod 191 that is movably set in the inner cavity of the positioning cylinder 170 and extends downward from the positioning cylinder 170, and a spring 192 connecting the T-shaped rod 191 and the inner top wall of the positioning cylinder 170. The T-shaped rod 191 can pass through the positioning hole on the PCB board to ensure the stability of the PCB board when it is plugged in. The spring 192 can keep the T-shaped rod 191 in an extended state, and at the same time, when the T-shaped rod 191 encounters resistance, the T-shaped rod 191 can be easily retracted into the inner cavity of the cylinder 172.

[0033] The collision sensor 180 can detect a collision signal. When the positioning rod 190 retracts into the inner cavity of the cylinder 172 and collides with the collision sensor 180 , it can be determined that the positioning rod 190 has not been accurately inserted into the positioning hole of the PCB board.

[0034] The adjustment mechanism 200 is used to adjust the lateral position of the positioning rod 190, and includes a second threaded sleeve 210 fixed on the top of the base 140, a second adjustment rod 220 arranged through the second threaded sleeve 210, a sleeve 230 rotatably installed at the end of the second adjustment rod 220, and a movable rod 240 that is slidably engaged on both sides of the sleeve 230 and whose ends are fixedly connected to the positioning cylinder 170.

[0035] The second adjusting rod 220 includes a second threaded rod 221 that passes through the second threaded sleeve 210 and a second knob 222 that is fixed to the end of the second threaded rod 221. The second threaded rod 221 and the second threaded sleeve 210 are engaged with each other, so that when the second knob 222 drives the second threaded rod 221 to rotate, the second threaded rod 221 rotates in the second threaded sleeve 210 and can be extended and retracted forward and backward, thereby driving the sleeve 230 to extend and retract.

[0036] A bearing 231 is fixed in the middle of the sleeve 230, and the end of the second threaded rod 221 is fixed to the inner ring of the bearing 231 to prevent the rotation of the second threaded rod 221 from affecting the sleeve 230. Sockets 232 are opened on both sides of the sleeve 230, and the movable rod 240 is slidably engaged in the sockets 232 to avoid affecting the movement between the positioning cylinders 170 on both sides.

[0037] The working principle and use process of the utility model are as follows: when in use, the conveyor belt 120 moves the PCB board to the specified position, the electric telescopic rod 132 is started, and the base 140 is driven to move downward, and the downward movement of the base 140 drives the movable seat 160 to move downward, and the downward movement of the movable seat 160 drives the positioning rod 190 to move downward, so that the positioning rod 190 is inserted into the positioning hole on the PCB board to position the PCB board. When the position of the PCB board is offset, the positioning rod 190 contacts the top of the PCB board during the downward movement. At this time, the positioning rod 190 retracts into the positioning cylinder 170 and collides with the collision sensor 180. The collision sensor 180 detects the collision signal, determines that the position of the PCB board is offset, and sends an alarm to the upper computer. The signal reminds the personnel to correct the position of the PCB board in time. When it is necessary to correct PCB boards of different sizes, the first knob 152 is turned to drive the first threaded rod 151 to rotate. The rotation of the first threaded rod 151 drives the first threaded sleeves 162 on both sides to move toward each other, that is, drives the U-shaped frames 161 on both sides to move toward each other, and adjusts the distance between the relative positioning rods 190. The second knob 222 is turned to drive the second threaded rod 221 to rotate. The second threaded rod 221 rotates in the second threaded sleeve 210, driving the sleeve 230 to move laterally. The movement of the sleeve 230 drives the positioning cylinder 170 to move laterally, that is, drives the positioning rod 190 to move laterally, and adjusts the lateral position of the positioning rod 190.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
