[0029] See also Figures 1 to 3 In the specific embodiment shown, the utility model discloses a positioning device for resin grinding of printed circuit boards, comprising: a positioning frame 10, wherein the positioning frame 10 is mounted on a resin grinding loading table 40, and the positioning frame 10 is provided with a positioning adjustment component 20 in the discharge direction, wherein the positioning adjustment component 20 comprises a first positioning block 21 and a second positioning block 22, wherein the first positioning block 21 and the second positioning block 22 are slidably connected to the positioning frame 10, and a positioning area is formed between the first positioning block 21 and the second positioning block 22.

[0030] Specifically, the resin grinding loading table 40 is located in front of the grinder, and the positioning frame 10 is arranged in front of the resin grinding loading table 40, that is, it is installed on the resin grinding loading table 40 through the positioning frame 10, and the positioning frame 10 is provided with a positioning adjustment component 20 in the discharge direction, and the positioning adjustment component 20 includes a first positioning block 21 and a second positioning block 22, and the first positioning block 21 and the second positioning block 22 are slidably connected to the positioning frame 10, and a positioning area is formed between the first positioning block 21 and the second positioning block 22, so that the corresponding positioning area can be adjusted according to the size of the circuit board, so that each time the material is discharged, it is placed along the positioning area, and then the circuit board is moved along the resin grinding loading table 40 to the grinder, so that the placed circuit board reaches the predetermined position each time, which solves the problem of circuit board placement position deviation caused by manual placement of the board, so as to improve the grinding effect of the circuit board.

[0031] Specifically, the grinding machine adopts the existing public technology, which will not be elaborated here.

[0032] In one embodiment, the positioning frame 10 includes a transverse portion 11, and the positioning adjustment assembly 20 is disposed on the transverse portion 11. The upper surface of the transverse portion 11 and the upper surface of the resin grinding loading platform 40 are in the same horizontal plane.

[0033] Specifically, the transverse portion 11 is arranged in the left-right direction, and by arranging the transverse portion 11 and the resin grinding loading platform 40 at the same horizontal plane, the problem of circuit board position deviation caused by imbalance can be effectively avoided after the circuit board is placed. Therefore, this design can improve the accuracy and stability of circuit board placement, thereby further improving the grinding effect and production efficiency.

[0034] In one embodiment, connecting legs 12 are disposed on both sides of the positioning frame 10 , and the connecting legs 12 are fixed to the side surfaces of the resin grinding loading platform 40 .

[0035] Specifically, the connecting pins 12 are fixed to the side of the resin grinding loading platform 40 to ensure a stable connection between the positioning frame 10 and the resin grinding loading platform 40. The presence of the connecting pins 12 enables the positioning frame 10 to be firmly fixed to the side of the resin grinding loading platform 40, thereby providing stable support and positioning during the process of unloading the circuit board, thus avoiding the problem of circuit board position deviation caused by looseness or instability of the positioning frame 10 during the unloading process.

[0036] In one embodiment, the connecting foot 12 is fixed to the side of the resin grinding loading platform 40 by means of screws 13 .

[0037] Specifically, by using the screws 13 to fix the connecting pins 12, a more firm and reliable connection can be provided, thereby avoiding the problem of circuit board position deviation caused by loose or unstable connection of the positioning frame 10 during the circuit board discharge process.

[0038] In one embodiment, a timer 30 is further disposed on the side of the positioning frame 10 .

[0039] Specifically, when placing circuit boards manually, it is difficult to ensure that the time intervals between placing circuit boards are uniform due to the limitations of operation control. It is often the case that the time distances between placed circuit boards are too close to each other, which will not only cause the grinder to alarm, but also require the grinder to reverse and eject the placed circuit boards, resulting in a waste of time and being detrimental to the intelligent operation of the production line. Therefore, by setting a timer 30, the timing starts when the previous circuit board is placed, and when the set time is reached, the timer 30 automatically issues a reminder, and the next circuit board can be placed to solve the rework problem caused by the short time distance between circuit boards due to the limitations of operation, that is, the time distance between circuit boards can be made continuous and stable, reducing the number of resin grinding reworks, improving mechanization capabilities, reducing labor, and also improving labor efficiency, reducing quality problems caused by circuit board grinding rework.

[0040] In one embodiment, the resin grinding loading platform 40 is provided with an infrared sensor (not shown in the figure) and a controller (not shown in the figure), and the timer 30 and the infrared sensor are electrically connected to the controller.

[0041] Specifically, according to production requirements, an interval time (for example, 20 seconds or 30 seconds) is set on the controller in advance. After the previous circuit board is placed, the infrared sensor senses the circuit board and sends a sensing signal to the controller. The controller transmits the signal to the timer 30, and the timer 30 starts timing. When the circuit board moves out of the sensing of the infrared sensor, the infrared sensor sends a non-sensing signal to the controller. The controller transmits the signal to the timer 30, and the timer 30 automatically issues a reminder (for example, a ringing sound or a flashing light). At this time, the next circuit board can be placed.

[0042] In one embodiment, the timer 30 is electrically connected to the controller via a wire.

[0043] Specifically, the role of this design is to achieve electrical connection between the timer 30 and the controller, so that the controller can monitor and control the operation of the timer 30.

[0044] In one embodiment, the resin grinding loading platform 40 is provided with a pressure sensor (not shown in the figure) and a controller, and the timer 30 and the pressure sensor are electrically connected to the controller.

[0045] Specifically, after the previous circuit board is placed, the pressure sensor senses the circuit board and sends a sensing signal to the controller, which transmits the signal to the timer 30, and the timer 30 starts timing; when the circuit board moves out of the pressure sensor sensing, the pressure sensor sends a non-sensing signal to the controller, and the controller transmits the signal to the timer 30, and the timer 30 automatically issues a reminder (for example: a ringing sound or a flashing light), and the next circuit board can be placed at this time.

[0046] In one embodiment, a support beam (not shown in the figure) is provided in the middle of the resin grinding loading platform 40, and the pressure sensor is provided on the support beam.

[0047] Specifically, the support beam plays a supporting role during the movement of the circuit board. The pressure sensor is arranged on the support beam to accurately detect the gravity of the circuit board to control the interval time of unloading the circuit board.

[0048] In one embodiment, a plurality of rollers 50 arranged side by side are provided on the resin grinding loading platform 40, and the rollers 50 rotate to drive the printed circuit board to move.

[0049] Specifically, when the size of the circuit board is large, the resin grinding loading table 40 can be provided with several roller groups along the left and right directions, each roller group is composed of several front and rear rollers 50, and the support beam can be provided between adjacent roller groups. When the circuit board is placed along the positioning area, the roller 50 rotates to drive the circuit board to move forward until it enters the grinding machine.

[0050] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
