Embodiment 1

[0035] This embodiment provides a flipping and clamping device for a soldering device, as Figure 1As shown in the figure, it is a schematic structural diagram of this embodiment. The flipping and clamping device for a soldering equipment provided in this embodiment includes: a flipping bracket 1, a strip-shaped material plate 2, a rotating motor 3, and a first synchronous belt assembly 31.

[0036] Among them, in this embodiment, the part to be soldered 5 to be soldered is flat and has two pairs of mirror-symmetrical pins 51. When soldering, the part to be soldered 5 needs to be flipped once so that the two pairs of pins 51 can complete the operations of dipping in flux and tin immersion. In this embodiment, the strip-shaped material plate 2 is used to clamp the part to be soldered 5 to be soldered and position it, so that the pins 51 of the part to be soldered 5 can be convenient for subsequent soldering operations. The flipping bracket 1 is used to fix other components and drive the strip-shaped material plate 2 to move and flip. The rotating motor 3 and the first synchronous belt assembly 31 are used to realize the flipping movement of the strip-shaped material plate 2 and accurately control the flipping angle of the strip-shaped material plate 2 to improve the processing accuracy.

[0037] The flipping bracket 1 includes a vertical mounting plate 11 and a pair of cantilevers 12 respectively mounted on both sides of the vertical mounting plate 11. The ends of the cantilevers 12 face downward, and a rotating block 4 is mounted at the end.

[0038] Among them, the cantilever 12 is used to mount the strip-shaped material plate 2 and can extend the strip-shaped material plate 2 downward, reducing the possibility of interference from other components to the strip-shaped material plate 2. The cantilever 12 can be plate-shaped, and the rotating block 4 can be mounted at the end of the cantilever 12 through a rotating shaft and a bearing. The rotating block 4 is used to mount the strip-shaped material plate 2 and is connected to the first synchronous belt assembly 31 to transmit the rotational motion output by the rotating motor 3 to the strip-shaped material plate 2, so that the strip-shaped material plate 2 can drive the part to be soldered 5 to flip.

[0039] As Figure 2 shown, it is a schematic installation diagram of the part to be soldered on the strip-shaped material plate in this embodiment. In this embodiment, both ends of the strip-shaped material plate 2 are respectively connected to two rotating blocks 4; several positioning protrusions 21 are evenly distributed in the middle part of the strip-shaped material plate 2, dividing the strip-shaped material plate 2 into several bearing positions 22; blind holes are provided in the bearing positions 22, and magnets 23 for adsorbing the part to be soldered 5 are installed in the blind holes.

[0040] Among them, both ends of the strip-shaped material plate 2 can be fixedly installed on the rotating block 4 through bolts, so that the strip-shaped material plate 2 can be flipped along with the rotating block 4. The positioning protrusion 21 can play a role in separating and positioning, preventing the distance between the parts 5 to be welded from being too close and affecting subsequent soldering operations. Blind holes for installing the magnet 23 are provided on the bearing position 22, so as to fix and install the parts 5 to be welded by adsorbing the parts 5 to be welded with the magnet 23. The magnetic force of the magnet 23 can be set as required to ensure that the parts 5 to be welded will not move easily after being adsorbed on the bearing position 22 and can be unloaded relatively easily. When operating on the parts 5 to be welded with magnetic cores in this embodiment, the direction of the magnet 23 in the blind hole needs to be set to improve the installation stability of the parts 5 to be welded. Compared with using mechanisms such as clamping jaws to clamp the parts 5 to be welded, using the magnet 23 in this embodiment can simplify the overall structure and prevent interference during operations such as dipping flux and tin dipping. This embodiment can reduce the weight of the strip-shaped material plate 2, make its flipping accuracy higher, further accurately control the rotation and movement of the pins 51 of the parts 5 to be welded, prevent excessive dipping of flux from contaminating the parts 5 to be welded, and can control the tin dipping depth, thereby improving the welding quality.

[0041] The bearing position 22 has a preset width, so that when the parts 5 to be welded are installed on the bearing position 22, the pins 51 of the parts 5 to be welded are exposed on both sides of the strip-shaped material plate 2.

[0042] Among them, the width of the bearing position 22 is the width of the strip-shaped material plate 2, and this dimension needs to be designed according to the size of the parts 5 to be welded to ensure that the parts 5 to be welded are stably installed on the bearing position 22 and the pins 51 can be exposed on both sides of the strip-shaped material plate 2, so that the strip-shaped material plate 2 is not contaminated when the pins 51 are dipped in flux and tin dipped and other operations.

[0043] The rotating motor 3 is installed on a cantilever 12. The first synchronous belt assembly 31 connects the rotating motor 3 and the rotating block 4, and drives the strip-shaped material plate 2 to rotate through the rotating block 4.

[0044] Among them, the rotating motor 3 can be a stepping lifting motor 66. The output end of the rotating motor 3 is connected with a driving wheel, and the rotating block 4 installed on the same cantilever 12 as the rotating motor 3 is installed with a driven wheel. The driving wheel and the driven wheel are connected by a synchronous belt, so as to realize the rotation of the strip-shaped material plate 2.

[0045] This embodiment can clamp multiple multi-pin 51 parts to be soldered 5 at one time through the strip-shaped material plate 2. The parts to be soldered 5 with pins 51 generally have magnetism or can be attracted by the magnet 23. In this embodiment, the parts to be soldered 5 are fixed at the bearing position 22 of the strip-shaped material plate 2 through the magnet 23, without other clamping structures, and the overall structure is simple, which is beneficial to subsequent soldering operations. In this embodiment, by setting the width of the bearing position 22, the pins 51 of the parts to be soldered 5 can be exposed on the left and right sides of the strip-shaped material plate 2, facilitating the flipping of the strip-shaped material plate 2 so that the pins 51 on both sides are successively downward for soldering operations, without the need for multiple clampings. Therefore, compared with the prior art, the flipping clamping device for soldering equipment provided by this embodiment has a simple structure, can clamp multiple multi-pin 51 parts to be soldered 5 at one time, and the parts to be soldered 5 are stably installed, and multiple pins 51 in different directions of the parts to be soldered 5 can be soldered in one clamping, improving the processing efficiency. Embodiment 2

[0046] As Figure 3 shown, it is a schematic structural diagram of this embodiment. The flipping clamping device for soldering equipment provided by this embodiment further includes an XZ moving mechanism 6. The vertical mounting plate 11 is fixedly installed on the moving end of the XZ moving mechanism 6, and the XZ moving mechanism 6 is used to drive the flipping bracket 1 to move in the X-axis and Z-axis directions.

[0047] Among them, after the part to be soldered 5 is rotated, it is necessary to move the part to be soldered 5 for operations such as dipping in flux and tin dipping. It is necessary for the part to be soldered 5 to move in the X-axis and Z-axis directions. Therefore, it is necessary to install the XZ moving mechanism 6. The XZ moving mechanism 6 in this embodiment can be any mechanism that can drive the vertical mounting plate 11 to move in the X-axis and Z-axis directions. The X-axis direction is the arrangement direction of components such as the flux tank and the solder bath, and the Z-axis direction is the vertical direction.

[0048] In this embodiment, the XZ moving mechanism 6 includes a pair of parallel gantry brackets 61. An X-axis moving plate 62 is installed on the gantry brackets 61. The X-axis moving plate 62 is driven by a transverse moving electric cylinder 63 to move on the gantry brackets 61. A vertical plate 64 is vertically installed on the X-axis moving plate 62. The vertical plate 64 is parallel to the vertical mounting plate 11, and the vertical plate 64 and the vertical mounting plate 11 are connected through a lead screw assembly 65. A lifting motor 66 for driving the lead screw assembly 65 is arranged on the vertical plate 64. The lead screw assembly 65 and the lifting motor 66 are connected through a second synchronous belt assembly 67. A guide rail 68 is further arranged between the vertical plate 64 and the vertical mounting plate 11.

[0049] Among them, in this embodiment, soldering related equipment such as feeding device, flux tank, solder tank, etc. can be arranged between parallel gantry brackets 61. In this embodiment, the XZ moving mechanism 6 is driven by the lateral electric cylinder 63 to move in the X-axis direction as a whole, with good positioning accuracy, and the vertical movement of the strip material plate 2 is achieved by the lead screw assembly 65 and the synchronous belt, which can ensure the movement accuracy and improve the soldering quality.

[0050] like Figure 4 The figure shows the installation schematic diagram of the downward pressing and pushing mechanism in this embodiment. The flip clamping device for soldering equipment provided in this embodiment also includes a downward pressing and pushing mechanism 7, which is arranged in the middle of the vertical mounting plate 11, including a horizontal mounting plate 71 fixedly mounted on the vertical mounting plate 11, and a pair of guide plates 72 parallel to the cantilever 12 are mounted on both sides of the horizontal mounting plate 71; downward pressing cylinders 73 are mounted on the two guide plates 72, and a downward pressing plate 74 is mounted between the moving ends of the two downward pressing cylinders 73, and the downward pressing plate 74 is used to push the parts to be welded 5 downward and position the parts to be welded 5.

[0051] Among them, the strip material plate 2 rotates 90 degrees to make the pin 51 on one side of the part 5 to be welded vertically downward, and then moves downward as a whole to dip the soldering flux. After the soldering flux is dipped, it will be moved to the solder tank for tinning. The above steps require that the pins 51 of all the parts 5 to be welded are highly consistent in the vertical direction, so further positioning is required. The downward pressing and pushing mechanism 7 in this embodiment positions the above-mentioned parts 5 to be welded, and the lower pressing plate 74 is a horizontal plate, and the size of the parts 5 to be welded is consistent. When the strip material plate 2 rotates 90 degrees, it is only necessary to contact the lower pressing plate 74 from above the parts 5 to be welded, so that the upper ends of the parts 5 to be welded are aligned, and the pins 51 of the parts 5 to be welded facing downward can be aligned to complete the positioning. Preferably, a positioning plate is set below the parts 5 to be welded, and after the strip material plate 2 rotates 90 degrees, the pins 51 of the parts 5 to be welded facing downward are in contact with the positioning plate, and the lower pressing plate 74 applies pressure to the parts 5 to be welded from above. This embodiment can improve the neatness of the pins 51 of the parts 5 to be welded, thereby improving the soldering quality.

[0052] like Figure 5 , which is a side view of the push mechanism in this embodiment. In this embodiment, there are two groups of push plates 74 and push cylinders 73, and the two groups of push plates 74 are respectively arranged above the strip material plate 2 when it is turned 90 degrees clockwise and counterclockwise.

[0053] Among them, the pins 51 of the part 5 to be welded are exposed on the left and right sides of the strip-shaped material plate 2. Therefore, when the strip-shaped material plate 2 is rotated clockwise or counterclockwise by 90 degrees, only the pins 51 on one side of the part 5 to be welded can be vertically downward. To complete the soldering of the pins 51 on both sides, the strip-shaped material plate 2 needs to be rotated 90 degrees in two directions on one side, and the position of the part 5 to be welded on the horizontal plane will move. In order to improve the positioning effect, two sets of lower pressing plates 74 are required, which are respectively driven by two sets of lower pressing cylinders 73. One lower pressing plate 74 is used for positioning when the strip-shaped material plate 2 is rotated 90 degrees clockwise, and the other lower pressing plate 74 is used for positioning when the strip-shaped material plate 2 is rotated 90 degrees counterclockwise.

[0054] As Figure 6 shown, it is the front view of the lower pressing and feeding mechanism in this embodiment. In this embodiment, vertically downward elastic buffer members 8 are installed on the lower pressing plate 74. The number of the elastic buffer members 8 is the same as the number of the bearing positions 22, and the installation positions of the elastic buffer members 8 on the lower pressing plate 74 correspond to the positions of the bearing positions 22 one by one.

[0055] Among them, the elastic buffer member 8 can be a spring 82 buffer member or a buffer structure with rubber, which can reduce the impact and vibration during the positioning of the part 5 to be welded, prevent the part 5 to be welded from falling or damaging the part 5 to be welded. The buffer members correspond to the parts 5 to be welded one by one, further improving the positioning effect.

[0056] As Figure 7 shown, it is the installation schematic diagram of the elastic buffer member in this embodiment. In this embodiment, the elastic buffer member 8 includes a pressure rod 81, a spring 82, and a linear bearing 83. The pressure rod 81 is installed on the lower pressing plate 74 through the linear bearing 83, and the spring 82 is sleeved on the pressure rod 81 to make the pressure rod 81 have a downward elastic force.

[0057] Among them, the lower end of the pressure rod 81 has a disc-shaped pressing head, and the upper end of the pressure rod 81 is fixed by a nut, so that the pressure rod 81 is installed on the lower pressing plate 74. The spring 82 can be arranged between the pressing head and the lower pressing plate 74. The linear bearing 83 can further eliminate the impact and vibration during movement and can bear a large load. And the linear bearing 83 has damping performance, which can improve the stability of the lower pressing plate 74. Embodiment 3

[0058] As Figure 8 shown, it is the structural schematic diagram of this embodiment. In this embodiment, ventilation openings are provided on the horizontally installed plate 71, and a ventilation duct 13 is connected to the ventilation openings.

[0059] Among them, the horizontally installed plate 71 is arranged between two cantilevers 12. During the soldering process, it will pass above the flux storage tank and the solder bath. The provision of the ventilation openings and the ventilation duct 13 can reduce pollution.

[0060] As shown Figure 9 in the figure, it is a structural schematic diagram of the rotating block in this embodiment. In this embodiment, the strip-shaped material plate 2 is in an "I" shape. The rotating block 4 includes a first plate body 41 parallel to the cantilever 12 and a second plate body 42 perpendicular to the cantilever 12. The end of the strip-shaped material plate 2 is fixedly connected to the second plate body 42 by bolts.

[0061] Among them, the strip-shaped material plate 2 is in an "I" shape, with larger installation positions at both ends, which is convenient for installation and fixation and maintains the width of the middle part. The first plate body 41 of the rotating block 4 is connected to the cantilever 12 through a rotating shaft, and a bearing is installed on the rotating shaft. The second plate body 42 of the rotating block 4 is perpendicular to the cantilever 12, which can better fix with the strip-shaped material plate 2, forming a cradle structure for the strip-shaped material plate 2 and improving the installation stability.

[0062] As shown Figure 10 in the figure, it is an installation schematic diagram of the detection mechanism in this embodiment. In this embodiment, it further includes a differential head 9, a photoelectric switch 91, and a rotation origin switch 92. The differential head 9 is installed on the rotating block 4 and is used to adjust the parallelism of the strip-shaped material plate 2; the photoelectric switch 91 is used to detect the displacement of the strip-shaped material plate 2 in the vertical direction; the rotation origin switch 92 is used to detect the rotation angle of the strip-shaped material plate 2.

[0063] Among them, the differential head 9 is installed on the rotating block 4, and the detection head abuts against the side of the strip-shaped material plate 2 to ensure the accuracy of the rotation angle of the strip-shaped material plate 2. The photoelectric switch 91 is installed on the cantilever 12 and the guide rail 68 and is used to detect the displacement of the strip-shaped material plate 2 in the vertical direction. The rotation origin switch 92 is installed on the cantilever 12 and the rotating shaft and is used to detect the rotation angle of the strip-shaped material plate 2. By installing the photoelectric detection device in this embodiment, the installation accuracy and displacement accuracy of the strip-shaped installation plate are further improved, the soldering quality can be improved, and a good yield rate can also be ensured when the pins 51 of the parts 5 to be soldered are relatively small.

[0064] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
