[0036] Specifically, the loading barrel 20 includes a barrel body 21 and a discharge pipe 23. The barrel body 21 is connected to the frame 10. A receiving cavity with an opening is formed in the barrel body 21. A discharge port is provided on a side wall of the receiving cavity near the bottom. The inlet of the discharge pipe 23 is connected to the discharge port. A receiving cavity with an opening is formed in the barrel body 21. A discharge port is provided on a side wall of the receiving cavity near the bottom. The discharge port can be set at the bottom wall of the receiving cavity or at the side wall of the receiving cavity. When the barrel body 21 is placed in a vertical direction, the discharge port is set at the bottom wall or side wall of the receiving cavity, which can facilitate the discharge of the solder paste inside the barrel body 21 from the bottom of the barrel body 21; when the barrel body 21 is placed in an inclined or horizontal direction, the discharge port is set at the bottom wall of the receiving cavity to avoid the problem of incomplete discharge due to the solder paste inside the barrel body 21 being far away from the discharge port. One end of the discharge pipe 23 is connected to the discharge port, and the other end is used for the output of the solder paste material.

The weighing instrument 41 can be arranged on the upper surface of the support plate or inside the support plate 43. The support plate 43 has the function of supporting and accommodating the weighing instrument 41, maintaining the position of the weighing instrument 41 and improving the measurement stability and accuracy of the weighing instrument 41. The weighing instrument 41 is electrically connected to the electric control mechanism 60. When the solder paste can or solder paste barrel is placed on the weighing instrument 41 and solder paste is added inside, the data measured by the weighing instrument 41 can be transmitted and communicated with the electric control mechanism 60 in real time to measure the weight of the solder paste can or solder paste barrel. The electric control mechanism 60 can obtain the measurement data of the weighing instrument 41, that is, the weight data of the solder paste can or solder paste barrel. When the measurement data of the weighing instrument 41 obtained by the electric control mechanism 60 reaches the preset weight value, the electric control mechanism 60 can control the pressing mechanism 30 to stop running, thereby stopping the material feeding.

[0038] Furthermore, the dividing mechanism 50 includes a second driving member 51 and a dividing member 53. The second driving member 51 can be a motor, a cylinder, etc., and the dividing member 53 can be a blade, a scraper, etc. One end of the second driving member 51 is connected to the frame 10 and is located on one side of the outlet of the discharge pipe 23.

After the loading, weighing and splitting processes, it is moved to the next process through the conveyor belt, thereby realizing the coordination of the solder paste dispensing device 1 with other processes and realizing automated solder paste production.

[0043] Furthermore, if Figures 1 to 5 As shown, a receiving groove 431 is provided on one side of the support plate 43 facing the discharge pipe 23, and the weighing instrument 41 is arranged in the receiving groove 431. The arrangement of the receiving groove 431 and the arrangement of the weighing instrument 41 in the receiving groove 431 can maintain the position of the weighing instrument 41 on the support plate 43, thereby maintaining the balance of the weighing instrument 41 and the support of the bottom, and also maintaining the stability of the weighing instrument 41 inside the support plate 43 to avoid shaking or swinging during the measurement process.

[0044] Furthermore, if Figures 1 to 4 As shown, the depth of the receiving groove 431 is the same as the height of the weighing meter 41; and / or, the width of the receiving groove 431 is the same as the width of the weighing meter 41.

In addition, when the solder paste dispensing device 1 is adapted and installed with the production line, it can be moved from the support plate 43 to the weighing meter 41 with the help of the conveyor belt, and then moved from the weighing meter 41 to the support plate 43. The moving surface is flat and the transportation process is smooth.

[0045] Furthermore, if Figure 1 , Figure 2 , Figure 5As shown, the weighing mechanism 40 also includes a movable arm 70 and a connecting column. One end of the movable arm 70 is rotatably connected to the frame 10, and the other end of the movable arm 70 is connected to the connecting column, and the connecting column is connected to the support plate 43. The movable arm 70 is provided, and after being connected to the support plate 43, the movement of the support plate 43 can be realized. There are multiple joints connected in the horizontal direction on the movable arm 70, so that the support plate 43 can be moved to different positions in the horizontal direction. When the charging barrel 20 or the pressing mechanism 30 needs to be replaced, repaired or debugged, the movable arm 70 can be rotated to move the support plate 43 and the weighing instrument 41 away. In addition, a locking piece is also provided on the movable arm 70. When the movable arm 70 is rotated to a suitable angle, it can be locked by the locking piece to maintain the rotation position of the movable arm 70 and the position of the support plate 43, and maintain the stability of the support plate 43 in the working state.

[0046] Furthermore, if Figures 1 to 5 As shown, the second driving member 51 is a motor, the dividing member 53 is a blade, the second driving member 51 is connected to the blade, the blade is arranged in the horizontal direction, and the second driving member 51 drives the blade to rotate so as to cut the solder paste at the outlet of the discharge pipe 23. In this embodiment, the motor and the blade cooperate, the driving part of the motor and the blade are arranged in parallel with the outlet of the discharge pipe 23, and the motor drives the blade to rotate through the outlet of the discharge pipe 23 to achieve the division of the solder paste.

[0047] Furthermore, if Figure 3 As shown, the second driving member 51 is connected to one end of the blade, and the second driving member 51 drives the blade to rotate so that the other end of the blade reciprocates through and cuts the solder paste at the outlet of the discharge pipe 23; or Figure 4As shown, the second driving member 51 is connected to the center of the blade, and the second driving member 51 drives the blade to rotate so that both ends of the blade circulate through and cut the solder paste at the outlet of the discharge pipe 23 in sequence. In one embodiment, the second driving member 51 is a single-phase asynchronous motor, a DC motor, a stepping motor, etc. The second driving member 51 is connected to one end of the blade, and the second driving member 51 drives the blade to rotate so that the other end of the blade reciprocates through and cuts the solder paste at the outlet of the discharge pipe 23, that is, the second driving member 51 drives the blade forward to rotate from one side of the outlet of the discharge pipe 23 through the outlet to the other side for the first cutting, and the second driving member 51 drives the blade backward to rotate from the other side through the outlet of the discharge pipe 23 back to one side for the second cutting, and repeated forward and reverse rotations can achieve multiple cutting of the outlet of the discharge pipe 23 by the blade. In another embodiment, the second driving member 51 is a DC motor, an AC asynchronous motor, etc. The second driving member 51 is connected to the center of the blade. The second driving member 51 drives the blade to rotate so that both ends of the blade 51 circulate through and cut the solder paste at the outlet of the discharge pipe 23 in turn, that is, the second driving member 51 drives one side of the blade to rotate from one side of the outlet of the discharge pipe 23 through the outlet for the first cutting, and the second driving member 51 continues to drive the other side of the blade to rotate from one side of the outlet of the discharge pipe 23 through the outlet for the second cutting. The blade can be driven to rotate multiple times to cut the outlet of the discharge pipe 23 multiple times. It can be understood that the amount of cutting for the discharge of solder paste can be adjusted by adjusting the gap between the first cutting and the second cutting.

[0048] Furthermore, the material of the partition 53 is aluminum, stainless steel, polyethylene or polypropylene. Polymer materials such as polyester, polyethylene, polypropylene, etc. have good tin resistance. Because of their large molecular weight, after being stained with tin, the tin will interact with the van der Waals force between molecules, making it difficult for the tin to penetrate into the polymer material. The partition 53 made of this material can avoid contamination of the solder paste. Furthermore, a material with a tin-resistant coating added to the metal surface can also be used, such as stainless steel with a tin-resistant oxidation layer, because a layer of oxide film will be formed on its surface, making it difficult for tin to adhere.

[0049] Furthermore, if Figures 1 to 5 As shown, the solder paste dispensing device 1 further includes a solenoid valve 80, which is connected to the discharge pipe 23 and electrically connected to the electric control mechanism 60, and the solenoid valve 80 is used to control the opening and closing of the discharge pipe 23. The solenoid valve 80 is connected to the inside of the discharge pipe 23, and can control the opening and closing of the outlet of the discharge pipe 23, the flow rate of the discharge channel, etc., to achieve discharge control of the discharge pipe 23.
