Description

Technical Field

[0001] This utility model relates to the field of material supply devices, and more specifically, to a flux supply device. Background Technology

[0002] Flux is a chemical that needs to be applied to a workpiece before soldering to improve the quality of the solder. Most current supply devices use a lifting and movable structure to move a sponge block back and forth. When it descends, it is immersed in flux. Then, the sponge block with flux is lifted to a preset position, and an external device brings the workpiece into contact with the sponge block, so that flux adheres to the workpiece, thus achieving the supply effect.

[0003] While it can meet the supply requirements, there is still room for improvement. In particular, most of the current sponge blocks rely on simple soaking to apply flux, which can easily lead to insufficient adsorption. This will naturally affect the quality of flux adhesion to subsequent workpieces, and thus affect the soldering process of the workpieces. Therefore, it needs to be improved. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a flux supply device with a simple structure that can provide a squeezing action to the sponge block, so as to effectively absorb the flux and improve the quality of flux adhesion on subsequent workpieces.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a flux supply device, including a material tank, a bracket, a sponge block, and a cylinder; the sponge block is placed on the bracket, and the bracket is driven by the cylinder to move up and down to enter and exit the material tank; a pushing structure is installed on the bracket, and the pushing structure moves with the raising and lowering of the bracket to squeeze the sponge block.

[0007] In a preferred embodiment of this invention, the bracket includes a box with an open top, in which a sponge block is sandwiched, with its top surface higher than the top of the box. Multiple hooks, bent and folded outwards to the outside of the material trough, are fixedly provided on the box. These hooks are all connected to a pusher, which is connected to the piston rod end of a cylinder. First through holes for flux entry and exit are provided on both sides of the box. Support plates are fixedly provided on both ends of the box, with first guide holes on the support plates. The pushing structure includes a pusher and a spring. First guide rods are fixedly provided at both ends of the pusher's sidewalls, sliding through the first guide holes. Springs are sleeved on the first guide rods, providing an outward pushing force for the pusher. A protruding strip is provided on the inner wall of the material trough for pushing the pusher along its path, thus compressing the sponge block.

[0008] In a preferred embodiment of this invention, the pusher includes a pressure bar, and two first guide rods are fixedly disposed at both ends of the pressure bar. Multiple insert rods are fixedly disposed on the wall surface of the pressure bar near the first guide rods, with the insert rods corresponding to the positions of the first through holes on the same side, and the ends of the insert rods extending through the first through holes into the box body. The pressure bar converges and narrows towards the horizontal center plane in a direction away from the insert rods, forming a triangular prism structure with rounded edges. The cross-section of the convex strip is a semi-circular structure. During the lifting and lowering movement of the pusher, when the pressure bar passes through the convex strip, the pressure bar is subjected to force and moves towards the box body, and the insert rods squeeze the sponge block.

[0009] In the preferred embodiment of this utility model, the first through holes located on opposite sides of the box body are arranged in a staggered and spaced manner.

[0010] In a preferred embodiment of this invention, the bottom surface of the box is provided with a plurality of second through holes, which are evenly spaced along the length of the box.

[0011] In a preferred embodiment of this invention, the pusher is a cover structure with an open bottom, and the side of the pusher close to the material trough slides against the outer wall of the material trough; the cylinder is located inside the pusher, and the piston rod end of the cylinder is connected to the pusher, and the upward stroke of the cylinder driving the bracket is less than the depth of the pusher.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model provides a flux supply device, including a material tank, a bracket, a sponge block, and a cylinder. The sponge block is placed on the bracket, which is driven by the cylinder to move in and out of the material tank. A pushing structure is installed on the bracket, which moves with the lifting and lowering of the bracket to squeeze the sponge block, so that it can effectively absorb flux, thereby improving the quality of flux adhesion on subsequent workpieces. Moreover, this action is designed to match the lifting and lowering of the bracket, using the movement of the pushing frame as the external force for adjustment, eliminating the need for an additional drive structure and reducing costs.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown in the figure, a flux supply device is disclosed in a specific embodiment of the present invention, including a material tank 100, a bracket 200, a sponge block 300, and a cylinder 400; the sponge block 300 is disposed on the bracket 200, and the bracket 200 is driven by the cylinder 400 to move in and out of the material tank 100; a pushing structure 600 is installed on the bracket 200, and the pushing structure moves with the lifting and lowering of the bracket to squeeze the sponge block.

[0024] The aforementioned flux supply device effectively absorbs flux by squeezing a sponge block, which can improve the quality of flux adhesion on subsequent workpieces. Moreover, this action is designed to match the lifting of the bracket, using the movement of the pusher as the external force for adjustment, eliminating the need for an additional drive structure and reducing costs.

[0025] Furthermore, such as Figure 2 , Figure 3 As shown, the bracket 200 includes a box 220 with an open top, and a sponge block 300 is sandwiched inside the box 220 with its top surface higher than the top of the box. Multiple hooks 230, bent and folded outwards from the material trough, are fixedly provided on the box 220. Each hook 230 is connected to a pusher 500, which is connected to the piston rod end of a cylinder 400. The box 220 has first through holes 221 on both sides for flux entry and exit. These first through holes serve as the entry and exit points for flux, allowing the sponge block to absorb flux. The hooks and pusher are connected to the cylinder, driving the entire bracket to move vertically, allowing the sponge block to rise to the desired height.

[0026] Support plates 222 are fixedly provided on both ends of the box body 220, and the support plates 222 are provided with first guide holes 223; the push structure 600 includes a pusher 610 and a spring 620; the two ends of the side wall of the pusher 610 are fixedly provided with first guide rods 611, the first guide rods 611 slide through the first guide holes 223, and the spring 620 is sleeved on the first guide rods 611 to provide the pusher 610 with an outward pushing force; the inner wall of the material trough 100 is provided with a protrusion 110 for pushing the pusher 610 through, thereby squeezing the sponge block 300; the pusher moves along the first guide hole through the first guide rod, and when the pusher contacts the protrusion, it pushes the pusher to one side of the box body, overcoming the spring force, thereby squeezing the sponge block and making the sponge block better absorbent.

[0027] Furthermore, the pusher 610 includes a pressure strip 612, and two first guide rods 611 are respectively fixed at both ends of the pressure strip 612; multiple insert rods 613 are fixedly provided on the wall surface of the pressure strip 612 near the first guide rods 611, the insert rods 613 correspond to the positions of the first through holes 221 on the same side, and the ends of the insert rods 613 extend into the box body 220 through the first through holes 221; the cooperation between the first through holes and the insert rods can further limit the movement of the pusher, making it more stable; and by using the first through holes as the part where the insert rods enter and exit the box body, the insert rods can make full contact with the sponge block, satisfying the effect of squeezing the sponge block;

[0028] The pressure strip 612 converges and narrows towards the horizontal center plane in a direction away from the insertion rod 613, forming a triangular prism structure with rounded edges; the cross section of the protrusion 110 is a semi-circular structure, which allows the pressure strip and the protrusion to make effective contact, and the pressure strip can contact the protrusion from above or below and complete the push; thus, during the lifting and lowering movement of the push frame, when the pressure strip passes through the protrusion, the pressure strip is forced to move towards the box body, and the insertion rod squeezes the sponge block.

[0029] Furthermore, the first through holes 221 on opposite sides of the box 220 are arranged in a staggered manner, so that the part of the insert rod that pushes and squeezes the sponge block is staggered from the position of the first through hole on the other side, preventing or reducing the force on the sponge block and causing part of it to be squeezed out from the first through hole on the other side.

[0030] Furthermore, the bottom surface of the box 220 is provided with a plurality of second through holes 224, which are evenly spaced along the length of the box; this can further increase the conductive parts between the box and the material tank, making it easier for flux to enter and exit.

[0031] Furthermore, the pusher 500 is a cover structure with an open bottom. The side of the pusher 500 near the material trough 100 slides against the outer wall of the material trough 100. The cylinder 400 is located inside the pusher 500. The piston rod end of the cylinder is connected to the pusher. The upward stroke of the cylinder driving the bracket is less than the depth of the pusher. The material trough is bolted to the base plate, and the cylinder is mounted on the base plate via a stand. The base plate is equipped with second guide rods at both ends corresponding to the pusher. The pusher has sleeves fixed at both ends inside. The inner diameter of the sleeves matches the inner diameter of the second guide rods and their positions correspond. The pusher moves along the second guide rods through the sleeves. By setting the pusher, a barrier can be formed at the opening of the cylinder and the material trough to prevent flux from splashing onto the cylinder and affecting its use.

[0032] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
