Simple rosin dipping mechanism

Abstract

The invention provides a simple rosin dipping mechanism, which comprises a rosin groove arranged on a supporting seat, and further comprises at least one lifting plate, a plurality of rosin cups arranged on the lifting plate at intervals, a first driver, a plurality of clamping devices for clamping terminals and a second driver. When operation is started, a first driver can drive a lifting plate and a rosin cup to be completely immersed in rosin liquid of a rosin tank firstly, so that a small liquid storage tank is full of the rosin liquid and is lifted to the position above the rosin tank; then the second driver drives the clamping device to get close to the small liquid storage tank, so that the terminal is dipped with the rosin liquid; as the small liquid storage tank only stores a certain amount of rosin liquid, the situation that the rosin liquid splashes to the coil in the process of dipping the rosin liquid is avoided; and the rosin cup is arranged to elastically move along the vertical direction, so that the terminal moves downwards along the vertical direction and presses the rosin cup so as to enable the rosin cup to be compressed in a small stroke, thereby ensuring that the part of the terminal, which needs to be dipped with rosin, can be completely dipped with the rosin.

Description

Technical Field

[0001] The invention relates to the technical field of processing equipment, in particular to a simple rosin dipping mechanism. Background Art

[0002] Currently in the electronic components industry, tinning or soldering of terminals is a very common production process. Depending on the product structure and application field, the methods of rosin dipping on the market are also different.

[0003] In some electronic component fields, there are very strict quality requirements for the tinning of coil terminals. Therefore, rosin is added before tinning, and the rosin can only adhere to the terminals and cannot splash onto the product. Manual rosin dipping is not only inefficient, but the quality of the rosin dipping is affected by the proficiency of the operator and cannot be guaranteed. Although there are some automated production equipment for automatic rosin dipping, the quality of the rosin dipping is often not well guaranteed for coil products with very short exposed terminals and no splashing; and in order to ensure the quality of the rosin dipping, the structure of the automated rosin dipping is often complex and costly. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a simple rosin dipping mechanism to solve the above-mentioned problem.

[0005] The present invention adopts the following scheme:

[0006] The present application provides a simple rosin dipping mechanism, comprising a rosin groove arranged on a support seat, and also comprising at least one lifting plate, a plurality of rosin cups arranged at intervals on the lifting plate, a first drive, a plurality of clamping devices for clamping terminals, and a second drive;

[0007] The upper end surface of the rosin cup is provided with a small liquid storage groove, the height of which is adapted to the height of the terminal to be dipped in rosin liquid; and the rosin cup can be elastically moved in the vertical direction; the first drive is used to drive the lifting plate to move, so that the small liquid storage groove can be filled with rosin liquid from the rosin groove, and the small liquid storage groove filled with rosin liquid is located above the rosin groove; the second drive is used to drive the clamping device to move, so that the terminal clamped on the clamping device approaches and presses down the small liquid storage groove to complete the rosin dipping.

[0008] Furthermore, the rosin cup is movably arranged on the lifting plate in a vertical direction; and a compression spring is arranged between the rosin cup and the lifting plate.

[0009] Furthermore, the rosin cup is provided with a sliding rod, and the lifting plate is provided with a sliding groove adapted to the sliding rod.

[0010] Furthermore, the first drive is connected to a lifting horizontal plate, and connecting pieces connected to the two ends of the lifting plate are arranged on both sides of the lifting horizontal plate. Linear bearings and guide rods connected to the linear bearings are also arranged at both ends of the lifting horizontal plate.

[0011] Furthermore, a limiting member is arranged above the lifting horizontal plate.

[0012] Furthermore, the first drive is a cylinder.

[0013] Furthermore, a liquid level sensor is also provided on the rosin tank.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0015] The present invention provides a simple rosin dipping mechanism, wherein the first drive drives the lifting plate and the rosin cup to be completely immersed in the rosin liquid of the rosin tank at the beginning of operation, so that the small liquid storage tank is filled with rosin liquid and lifted to the top of the rosin tank; then the second drive drives the clamping device to approach the small liquid storage tank, so that the terminal clamped on the clamping device moves down to dip the rosin liquid in the small liquid storage tank; since the small liquid storage tank only stores a certain amount of rosin liquid, the rosin liquid will not splash onto the coil during the process of dipping the rosin liquid; and the rosin cup can be elastically moved in the vertical direction, so that after the terminal moves down in the vertical direction into the small liquid storage tank, the rosin cup is pressed down so that the rosin cup can be compressed with a small stroke, thereby ensuring that the part of the terminal that needs to be dipped in rosin can be completely dipped in rosin.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0024] Example

[0025] Combination Figures 1 to 5 As shown, this embodiment provides a simple rosin dipping mechanism, including a rosin groove 2 arranged on a support base 1, and also includes at least one lifting plate 3, a plurality of rosin cups 4 arranged at intervals on the lifting plate 3, a first drive 5, a plurality of clamping devices 6 for clamping a terminal 13, and a second drive (not shown in the drawings);

[0026] The upper end surface of the rosin cup 4 is provided with a small liquid storage groove 7, and the height of the small liquid storage groove 7 is adapted to the height of the terminal 13 that needs to be dipped in rosin liquid; and the rosin cup 4 can be elastically moved in the vertical direction; the first drive 5 is used to drive the lifting plate 3 to move, so that the small liquid storage groove 7 can be filled with rosin liquid from the rosin groove 2, and the small liquid storage groove 7 filled with rosin liquid is located above the rosin groove 2; the second drive is used to drive the clamping device 6 to move, so that the terminal 13 clamped on the clamping device 6 approaches and presses down the small liquid storage groove 7 to complete the rosin dipping.

[0027] Specifically, in this embodiment, Figures 1 to 4As shown, the first drive 5 adopts a cylinder, the piston rod of which is connected to a lifting horizontal plate 8, and the two sides of the lifting horizontal plate 8 are provided with connectors 9 connected to the two ends of the lifting plate 3, and the two ends of the lifting horizontal plate 8 are also provided with linear bearings 10 and guide rods 11 connected to the linear bearings 10; through the drive of the cylinder, the lifting horizontal plate 8 is driven to move in the vertical direction, thereby driving the lifting plate 3 to move in the vertical direction, so that the lifting plate 3 and the rosin cup 4 can be completely immersed in the rosin tank 2, and after the liquid storage tank 7 on the rosin cup 4 is full of rosin liquid, it is lifted to the top of the rosin tank 2, that is, the liquid storage tank 7 exposes the rosin liquid level in the rosin tank 2. The arrangement of the linear bearings 10 and the guide rods 11 can ensure that the lifting plate 3 can be lifted horizontally, and then ensure that the multiple rosin cups 4 arranged on the lifting plate 3 can be lifted horizontally synchronously, ensuring that the multiple rosin cups 4 are not skewed. Since the liquid storage tank 7 only stores a certain amount of rosin liquid, the rosin liquid will not splash onto the coil 12 during the process of taking the rosin liquid.

[0028] like Figure 1 and Figure 5 As shown, the bottom of the rosin cup 4 is provided with a sliding rod 14, and the lifting plate 3 is provided with a sliding groove adapted to the sliding rod 14; so that the rosin cup 4 can move in the vertical direction on the lifting plate 3; and a compression spring 15 is provided between the rosin cup 4 and the lifting plate 3, so that the rosin cup 4 can move elastically. The upper end surface of the rosin cup 4 is provided with a liquid storage groove 7, and the height of the liquid storage groove 7 is adapted to the height of the terminal 13 that needs to be dipped in rosin liquid, that is, the groove height of the liquid storage groove 7 is set within the height tolerance range of the terminal 13 that needs to be dipped in rosin liquid. The clamping device 6 clamps the terminal 13 to the top of the liquid storage tank 7, then moves down into the liquid storage tank 7, and presses down so that the rosin cup 4 moves a small stroke under the action of the compression spring 15, thereby ensuring that the part of the terminal 13 that needs to be dipped in rosin can be completely dipped in rosin, avoiding the terminal 13 from not moving down to a position and failing to completely dip in rosin liquid. At the same time, with the buffering assistance of the compression spring 15, the splashing of rosin liquid during the process of taking up rosin liquid is further avoided.

[0029] Preferably, a limiter 16 is provided above the lifting horizontal plate 8 to ensure that the rosin cup 4 can be lifted to a suitable position, thereby ensuring that the liquid storage tank 7 exposes the rosin liquid level in the rosin tank 2. Furthermore, a liquid level sensor 17 is provided on the rosin tank 2 to monitor the liquid level of the rosin tank 2 in real time, so as to determine when the rosin liquid needs to be added.

[0030] It should be noted that the number of the lifting plates 3 and the rosin cups 4 can be set according to actual conditions. For example, in this embodiment, since the terminals 13 at both ends of the coil 12 need to be dipped in rosin, two lifting plates 3 are provided, and six rosin cups 4 are provided on each lifting plate 3, so that the terminals 13 at both ends of the six coils 12 can be dipped in rosin at the same time.

[0031] This mechanism is designed for coils 12 with short exposed terminals 13 and no splashing. It not only realizes fully automated rosin dipping, but also has a simple structure and can realize high-precision and stable rosin dipping of multiple coils 12 at the same time, thus achieving high-efficiency production operations. It occupies a small space, has wide applicability and strong compatibility, and can be widely used in automated production rosin dipping equipment, and can also be used in fully automated production lines in other fields such as components.

[0032] The following is a detailed description of the agency's operating process:

[0033] At the beginning of the operation, the first drive 5 will drive the lifting plate 3 and the rosin cup 4 to be completely immersed in the rosin liquid in the rosin tank 2, so that the small liquid storage tank 7 is filled with rosin liquid and lifted to the top of the rosin tank 2; then the second drive will drive the clamping device 6 to approach the small liquid storage tank 7, so that the coil terminal 13 clamped on the clamping device 6 moves down, and presses down the rosin cup 4 so that the rosin cup 4 can be compressed with a small stroke, thereby completing the terminal 13 to dip in rosin; when the rosin is successfully dipped, the first drive 5 drives the lifting plate 3 and the rosin cup 4 to be immersed in the rosin liquid in the rosin tank 2 again, and this cycle is repeated.
