Description

Technical Field

[0001] The utility model relates to the technical field of watercolor pen production equipment, and particularly relates to an automatic assembly device for watercolor pens. Background Art

[0002] Watercolor pens are commonly used painting tools for children, usually packaged in boxes or bags. The pen tips are generally round, large, or soft. The advantages are sufficient moisture and rich and bright colors. The disadvantages are that it is not easy to replenish ink and the performance of gradient colors is not good. Generally, it is suitable for drawing children's paintings and can also be used as a marker pen. Watercolor pens usually need to be assembled and produced by an assembly machine. An assembly machine refers to a mechanical device that combines several parts of a product together through methods such as tight fitting, snap fitting, screw connection, adhesion, riveting, and welding to obtain a finished product (semi-finished product) that meets the predetermined dimensional accuracy and functions. During the production process of watercolor pens, automatic assembly needs to be carried out through a fully automatic assembly machine.

[0003] However, after the existing assembly machine finishes assembling the watercolor pens, they freely fall after passing through the conveyor belt. During the transmission process, the watercolor pens are placed in a mess. After discharging, the staff still needs to re-organize the watercolor pens, which not only causes waste of human resources but also affects the production efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic assembly device for watercolor pens to solve the problems mentioned in the above background art.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions: An automatic assembly device for watercolor pens includes a frame. Above the frame, there are an assembly mechanism and a conveyor belt. On one side of the frame, there is a first connecting frame. The conveyor belt extends towards the first connecting frame to one end of the frame. On the first connecting frame, there is a flipping seat. The end of the flipping seat away from the conveyor belt is rotatably connected to the first connecting frame. It also includes a driving device for driving the flipping seat to rotate. The height of the flipping seat is lower than that of the conveyor belt and it is inclined upwards towards the conveyor belt. Above the first connecting frame, there is a supporting block. The bottom of the flipping seat abuts against the supporting block. Above the flipping seat, there is a "C"-shaped enclosure with an opening facing the conveyor belt. On the side of the enclosure away from the conveyor belt, there is a pressure sensing device. Inside the flipping seat, there is a cavity. On the side wall of the flipping seat, there is an air passage communicating with the cavity, and on the top wall, there are several air holes communicating with the cavity. It also includes an air pump, which is connected to the air passage through a hose. It also includes a controller. The pressure sensing device and the driving device are both electrically connected to the controller. On the side of the first connecting frame away from the frame, there is a second connecting frame. Above the second connecting frame, there is a collection box. The height of the collection box is lower than that of the flipping seat.

[0006] By adopting the above technical scheme, after the watercolor pen is assembled in the assembly mechanism, it enters the top of the conveyor belt. After being sent to the end of the frame by the conveyor belt, the watercolor pen enters the top of the flip seat. The watercolor pen slides down to the lower side wall position of the enclosure under the action of gravity. Multiple watercolor pens are close to each other under the action of gravity, so as to be neatly arranged. When the pressure sensing device senses that the pressure generated by multiple watercolor pens reaches a preset value, the pressure sensing device sends a signal to the controller, and the controller controls the air pump to evacuate the inside of the cavity, thereby generating negative pressure at the air hole, and adsorbing the watercolor pen on the flip seat. Then the controller controls the driving device to drive the flip seat to deflect upward. When the flip seat deflects upward to above the collection box, the controller controls the air pump to inflate the cavity. At this time, the negative pressure disappears, and multiple watercolor pens fall into the collection box and are neatly arranged in a row, thereby eliminating the step of re-arranging the watercolor pens by staff after discharging, avoiding waste of human resources and improving production efficiency.

[0007] As a further optimization of the utility model, a pair of support seats are provided above the first connecting frame, a rotating shaft is fixed to the end of the flip seat, the rotating shaft is rotatably connected to the pair of support seats, the driving device is a motor, and the output end of the motor is connected to the rotating shaft.

[0008] With the above technical solution, the flip seat is rotatably connected to the support seat via the rotating shaft, and the motor drives the rotating shaft to rotate, thereby driving the flip seat to rotate.

[0009] As a further optimization of the utility model, a mounting frame is provided on both sides of the conveyor belt above the frame near the first connecting seat, a cylinder is provided above the mounting frame, the movable end of the cylinder faces downward and is connected to a baffle, and the cylinder is electrically connected to the controller.

[0010] With the above technical solution, when the pressure sensing device sends a signal to the controller, the controller controls the movable end of the cylinder to extend, thereby causing the baffle to move downward, blocking the watercolor pen on the conveyor belt and stopping it from moving.

[0011] As a further optimization of the present invention, the top of the support block is in an arc shape, and a groove is provided at the bottom of the flip seat, and the shape of the groove is adapted to the shape of the top of the support block.

[0012] By adopting the above technical solution, when the support block is reversely deflected and reset, the support block abuts and cooperates with the groove, which can support the flip plate more stably.

[0013] As a further optimization of the utility model, a plurality of arc-shaped grooves are equidistantly arranged on the inner bottom of the collection box, and the diameter of the arc-shaped grooves is the same as the outer diameter of the watercolor pen.

[0014] By adopting the above technical solution, when the watercolor pens fall into the collection box, the bottom row of watercolor pens can be fixed to the card slot, reducing the rolling deviation of the watercolor pens, so that the collected watercolor pens can remain neat when stacked in rows.

[0015] The utility model has the following beneficial effects: after the watercolor pen is assembled in the assembly mechanism, it enters the top of the conveyor belt, and after being sent to the end of the frame by the conveyor belt, it enters the top of the flip seat, and the watercolor pen slides down to the lower side wall position of the enclosure under the action of gravity. Multiple watercolor pens are pressed against each other under the action of gravity, so as to be neatly arranged. When the pressure sensing device senses that the pressure generated by multiple watercolor pens reaches a preset value, the pressure sensing device sends a signal to the controller, and the controller controls the air pump to evacuate the inside of the cavity, thereby generating negative pressure at the air hole, and adsorbing the watercolor pen on the flip seat, and then the controller controls the driving device to drive the flip seat to deflect upward, and when the flip seat deflects upward to above the collection box, the controller controls the air pump to inflate the inside of the cavity, and the negative pressure disappears at this time, and multiple watercolor pens fall into the collection box and are neatly arranged in a row, thereby eliminating the step of having the staff re-arrange the watercolor pens after discharging, avoiding waste of human resources, and improving production efficiency.

[0022] A flipping seat 3 is arranged on the first connecting frame 2, and one end of the flipping seat 3 away from the conveyor belt is rotatably connected to the first connecting frame 2; further includes a driving device 4 for driving the flipping seat 3 to rotate. Specifically, a pair of supporting seats 21 are arranged above the first connecting frame 2, a rotating shaft 32 is fixed at the end of the flipping seat 3, and the rotating shaft 32 is rotatably connected to the pair of supporting seats 21. The driving device 4 is a motor, and the output end of the motor is connected to the rotating shaft 32;

[0023] The height of the flipping seat 3 is lower than that of the conveyor belt and is inclined upwards towards the conveyor belt. A supporting block 22 is arranged above the first connecting frame 2, and the bottom of the flipping seat 3 abuts against the supporting block 22. Specifically, the top of the supporting block 22 is arc-shaped, and a groove 34 is opened at the bottom of the flipping seat 3, and the shape of the groove 34 is adapted to the shape of the top of the supporting block 22;

[0024] A retaining wall 31 in a "C" shape with an opening facing the conveyor belt is arranged above the flipping seat 3. A pressure sensing device 311 is arranged on the side of the retaining wall 31 away from the conveyor belt. A cavity 35 is opened inside the flipping seat 3. An air duct 33 communicating with the cavity 35 is arranged on the side wall of the flipping seat 3, and a plurality of air holes 36 communicating with the cavity 35 are opened on the top wall; further includes an air pump 6, and the air pump 6 is connected to the air duct 33 through a hose 61; further includes a controller 7, and the pressure sensing device 311 and the motor are both electrically connected to the controller 7;

[0025] A second connecting frame 5 is arranged on the side of the first connecting frame 2 away from the frame 1. A collection box 51 is arranged above the second connecting frame 5, and the height of the collection box 51 is lower than that of the flipping seat 3. Further, a plurality of arc-shaped grooves 511 are equidistantly arranged at equal intervals on the inner bottom of the collection box 51, and the diameter of the arc-shaped grooves 511 is the same as the outer diameter of the watercolor pen;

[0026] Further, mounting frames 8 are arranged on both sides of the conveyor belt near the first connecting seat above the frame 1. A cylinder 81 is arranged above the mounting frame 8, and the movable end of the cylinder 81 faces downwards and is connected to a baffle 9. The cylinder 81 is electrically connected to the controller 7.

[0027] The principle of the utility model is as follows: after the watercolor pen is assembled in the assembly mechanism 11, it enters the top of the conveyor belt. After being sent to the end of the frame 1 by the conveyor belt, the watercolor pen enters the top of the flip seat 3. The watercolor pen slides down to the lower side wall position of the enclosure 31 under the action of gravity. Under the action of gravity, multiple watercolor pens are closely attached to each other, so as to be neatly arranged. When the pressure sensing device 311 senses that the pressure generated by the multiple watercolor pens reaches a preset value, the pressure sensing device 311 sends a signal to the controller 7, and the controller 7 controls the air pump 6 to press the pressure in the cavity 35. The air is sucked out from the inside, thereby generating negative pressure at the air hole 36, and the watercolor pen is adsorbed on the flip seat 3. Then the controller 7 controls the driving device 4 to drive the flip seat 3 to deflect upward. When the flip seat 3 deflects upward to above the collection box 51, the controller 7 controls the air pump 6 to inflate the cavity 35. At this time, the negative pressure disappears, and multiple watercolor pens fall into the collection box 51 and are neatly arranged in a row. The bottom row of watercolor pens can be fixed with the card slot, reducing the rolling deviation of the watercolor pens, so that the collected watercolor pens can be kept neat when they are stacked in rows.

[0028] When the watercolor pen falls into the collection box 51 and is flipped and deflected back to reset, the support block 22 abuts against the groove 34, which can support the flip plate more stably;

[0029] Furthermore, when the pressure sensing device 311 sends a signal to the controller 7, the controller 7 can also control the movable end of the cylinder 81 to extend, so that the baffle 9 moves downward to block the watercolor pen on the conveyor belt and stop it from moving;

[0030] Through the above scheme, the step of requiring staff to re-arrange the watercolor pens after discharging is eliminated, thereby avoiding waste of human resources and improving production efficiency.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
