[0002] In order to ensure good contact effect of electronic products, the pins will be tinned during processing to prevent the pins from being oxidized. Traditionally, the tinning treatment of electronic product pins is done by manually soaking the pins in a flux container and a tin furnace to complete the tinning treatment. After the pins are tinned, the product is placed on the carrier. This operation method has the disadvantages of low tinning efficiency, poor tinning accuracy and high labor intensity for workers.

[0003] Later, in order to reduce the labor intensity of workers, the market began to use linear rails to transport electronic products and use robots to clamp electronic products for tinning. However, before tinning the product, it is necessary to dip it in flux first, and then tin it. After tinning, the tinned product needs to be electrically tested. Only after the electrical test is completed can the material be unloaded. This process is difficult to complete through linear rail transmission, and traditional linear rail transmission tinning is mostly a single product tinning operation, which has low work efficiency.

[0019] 2. The present invention realizes the loading operation through the loading hollow rotating module at the loading station, and in the loading process, multi-station loading is realized by arranging multiple rotating cylinders on the rotating platform. After the loading of one station is completed, the other rotating cylinder that needs to be loaded is rotated to the loading station through the rotation direction of the rotating platform. The rotating cylinder and the welding rod clamp holding the welding rod group that have completed loading can enter the next process, and the welding rod group on the welding rod clamp is obtained through the soldering gantry module. After the soldering gantry module is obtained, the rotating platform continues to rotate and can be transferred to the loading station for loading. Through the circular station design, operations such as product loading and product transfer and tinning can be carried out simultaneously, which greatly improves work efficiency.

[0020] 3. The present invention arranges electromagnets on both sides of the fixture fixing plate, and the welding rod group can be adsorbed and fixed by controlling the electromagnets. The welding rod group is set upward at the loading station, but when the solder gantry module is clamped, the welding rod group needs to be set downward. In this way, a 180-degree rotation can be achieved by rotating the cylinder, and the electromagnet can ensure that the welding rod group will not fall during the rotation.

[0021] 4. The transfer module structure of the present invention is the same as the structure of the feeding hollow rotating module. After the soldering gantry module completes the flux dipping and tinning operations, the welding rod group is transferred to the testing station, which is convenient for the soldering gantry module to continue to perform the next step of flux dipping and tinning operations.

[0022] 5. The present invention provides an electromagnet on the welding rod group, and the connection between the product and the welding rod group is controlled by the electromagnet. The connection control between the product and the welding rod group is achieved by controlling the on and off points of the electromagnet.

[0024] 7. The present invention sets a carrier centering module at the loading station, and the welding rod group can be centered by a pair of centering cylinders, so that the welding rod group is in the middle of the entire welding rod fixture. When the soldering gantry module takes the welding rod group, the soldering gantry module also takes the middle position.

[0025] 8. The welding rod group arranging module of the present invention can arrange the products on the welding rod group when the welding rod group is centered by means of the arranging platform arranged at the end of the arranging cylinder, so that the products are neatly arranged on the welding rod group. The distance can be accurately controlled during the subsequent dipping of flux and tinning, so as to achieve tinning of the pins and incisions without affecting other positions of the product.

[0026] 9. The solder gantry module of the present invention realizes the horizontal and vertical movement of the welding rod moving fixture with the welding rod group. The horizontal movement passes through the flux dipping station and the tin dipping station once, and the vertical movement enables the welding rod group to move the product into the tin pool and the flux pool.

[0027] 10. The welding rod moving clamp of the present invention is designed to be a pair of L-shaped fixing rods. After the L-shaped fixing rods are brought close to the welding rod clamp, the horizontal sections of the pair of L-shaped fixing rods support the welding rod group. The welding rod group can be taken out by moving the open end of the welding rod group horizontally and vertically. For the sake of stability, the welding rod group can be fixed on the horizontal section of the L-shaped fixing rod by a limiting cylinder.

[0028] 11. The present invention transfers the welding rod group to the automatic electrical testing station through the transfer module, facing the probe group of the electrical testing carrier plate, and drives the electrical testing carrier plate up and down through the electrical testing cylinder to realize automatic electrical testing, thereby realizing the automated electrical testing function.

[0029] 12. When unloading materials, the present invention turns the welding rod group upward, and the unloading operation is directly performed through the unloading gripper group. The mechanical arm realizes positioning. The cylinder slide rail in the unloading gripper group drives the slider on the slide rail to move up and down through the cylinder, driving the clamping claw cylinder below it to grab the product. When grabbing, the electromagnet on the welding rod group disconnects the power supply.

[0030] 13. The present invention directly transfers the tray filled with products from the empty tray lifting module to the full tray lifting module through the unloading tray gripper module, which can realize automatic tray loading and unloading. The empty tray lifting module and the full tray lifting module designed by the present invention can adjust the height of the stacked empty trays and the height of the full trays through the lifting slide rail. After the empty tray is filled and transferred to the full tray lifting module, the empty tray position can be lifted by the empty tray lifting module, which is convenient for continuing the unloading operation without human participation in the movement of the tray.

[0031] 14. The present invention also provides an empty tray loading module and a full tray unloading module. The operator only needs to place the empty tray on the first belt from one side of the frame. The stacked empty trays can be moved to the empty tray lifting module position through the first belt. The second belt transfers the full tray to the side exit position of the frame. The operator only needs to take out the full tray from one side of the frame, and it can be achieved without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0035] The present invention discloses a tinning test workstation, see Figures 1 to 14, including a frame 1, on which a loading station 2, a flux dipping station 3, a tin dipping station 4, an automatic electric measuring station 5 and a material unloading station 6 are arranged in sequence; a soldering gantry module 7 is also arranged above the flux dipping station 3 and the tin dipping station 4; a transfer module 8 is also arranged between the tin dipping station 4 and the material unloading station 6.

[0037] The flux dipping station 3 is provided with a flux pool 301, and the tin dipping station 4 is provided with a tin pool 401. The solder gantry module 7 clamps a group of welding rods 9 carrying products on the feeding hollow rotating module and passes through the flux dipping station 3 and the tin dipping station 4 in turn for flux dipping and tin dipping operations.

[0038] The transfer module 8 clamps the welding rod group 9 carrying the product on the solder gantry module 7 to the automatic electrical testing station 5 for automatic electrical testing.

[0039] The unloading station 6 is provided with a robot unloading module 601 and an unloading tray module 602 . After the automatic electrical measurement is completed, the welding rod group 9 products are unloaded to the unloading tray module 602 through the robot unloading module 601 .

[0040] See also Figure 2 The robot loading module includes a loading robot arm 204, at the end of which is an electric loading clamp 201, which can perform loading operations on products. An annular light source 202 and a camera 203 are arranged at the end of the loading robot arm 204 on one side of the electric loading clamp 201. The camera 203 is facing the annular light source 202, and the annular light source 202 is facing the grasping direction of the electric loading clamp 201, which is used for fill light to facilitate the camera 203 to shoot.

[0041] See also Figure 2 , Figure 3 and Figure 8The structure of the transfer module 8 is the same as that of the feeding hollow rotating module, including a rotating platform 205, at least one rotating cylinder 206 and a welding rod clamp 207. The rotating platform 205 is provided with a rotating drive assembly for controlling the rotation of the rotating platform 205, which is realized by a rotating servo motor 208 in this embodiment. A rotating cylinder fixing part 209 is fixed on the rotating platform 205, and a rotating cylinder 206 is fixedly connected to the rotating cylinder fixing part 209. In this embodiment, a pair of rotating cylinders 206 are provided, which are symmetrically arranged on the rotating cylinder fixing parts 209. The execution end of the rotating cylinder 206 is connected to the welding rod clamp 207 through a clamp fixing plate 210, and electromagnets 211 are also provided on both sides of the clamp fixing plate 210. In this embodiment, the welding rod clamp 207 is open in the direction away from the rotating cylinder 206 and has a cross-section of The purpose of the U-shaped fixture with an opening on one side is to facilitate the soldering gantry module to remove the welding rod group 9 from the welding rod fixture 207.

[0042] During loading, the welding rod group 9 is located in the welding rod clamp 207 and is fixed by energizing the electromagnet 211. At this time, the welding rod group 9 drives the upper welding rod to be set upward, and the end of the loading robot arm 204 grabs the product through the electric loading clamp 201 and places it on the top of the welding rod group 9. The product is adsorbed and fixed by the electromagnet at the top of the welding rod group 9. After loading is completed, the rotating platform 205 rotates 180 degrees, and the rotating cylinder 206 on the other side drives the empty welding rod group 9 to the loading position to continue loading. The welding rod group 9 that has completed loading can enter the next process.

[0043] See also Figure 3 The loading station 2 is also provided with a carrier centering module 213, which includes a pair of centering cylinders 2131. When the loading hollow rotating module clamps the welding rod group 9 and rotates to the loading position, the centering cylinders 2131 are executed to align the position of the welding rod group 9 between the loading hollow rotating module and the flux pool 301. The purpose of the carrier centering module 213 is to set the welding rod group 9 in the middle of the welding rod clamp 207. After the loading hollow rotating module clamps the welding rod group 9 and rotates to a fixed position, the rotating cylinder 206 rotates 180 degrees, and the welding rod group 9 drives the product on it to rotate 180 degrees. After the rotation, the product is downward, and the electromagnet 211 releases the welding rod group 9 at this time, and the welding rod group 9 is centered through the carrier centering module 213.

[0044] In addition, the loading station 2 is also provided with a welding rod group sorting module, which is located in the middle of a pair of centering cylinders 2131, including a sorting cylinder 2141 arranged up and down, a sorting platform 2142 arranged at the end of the sorting cylinder 2141, and a plurality of sorting protrusions 2143 arranged at intervals on the sorting platform 2142.

After the rotation, the product is downward, and the electromagnet 211 releases the welding rod group 9 at this time, and the welding rod group 9 is centered through the carrier centering module 213. At this time, the sorting protrusion 2143 is facing the product on the welding rod group 9, and the sorting cylinder 2141 is extended and retracted upward to control the sorting platform 2142 to drive the sorting protrusion 2143 thereon to squeeze the product of the welding rod group 9, so that the product is on a horizontal line.

[0045] See also Figure 4 and Figure 7 The soldering gantry module 7 includes a lateral moving component arranged along the sides of the flux dipping station 3 and the tin dipping station 4, a longitudinal moving component arranged on the lateral moving component, and a welding rod moving fixture arranged on the longitudinal moving component. The longitudinal moving component drives the welding rod moving fixture to move up and down, and the lateral moving component drives the longitudinal moving component and the welding rod moving fixture thereon to pass through the flux dipping station 3 and the tin dipping station 4 in sequence.

The lateral movement assembly is realized by the lateral movement slide rail 701, and the longitudinal movement assembly is realized by the longitudinal movement slide rail 702. A pair of lateral movement slide rails 701 are arranged on both sides of the fluxing station 3 and the tinning station 4, and the longitudinal movement slide rails 702 are symmetrically arranged on the pair of lateral movement slide rails 701. A pair of L-shaped fixed rods 704 are fixed on the longitudinal movement slide rail 702 through a gantry fixing plate 703. When the soldering gantry module 7 takes the welding rod group 9, it is only necessary to move the slide rail 701 laterally to drive a pair of L-shaped fixing rods 704 close to the welding rod clamp 207. When the horizontal section of the L-shaped fixing rod 704 takes over the welding rod group 9, the limiting cylinder 705 works to press the welding rod group 9 against the horizontal section of the L-shaped fixing rod 704, and then drive the welding rod group 9 to leave the welding rod clamp 207 by moving the slide rail 701 laterally.

[0047] During the movement of the soldering gantry module 7 with the soldering rod group 9, the soldering gantry module 7 passes through the soldering flux dipping station 3 and the soldering tin dipping station 4. In this embodiment, the soldering flux dipping station 3 is referred to as Figure 5The flux dipping station 3 designed by the present invention is provided with a flux limiting plate 303 in the flux pool 301, which is controlled by the lifting cylinder 302. A plurality of flux limiting slots 306 are arranged at intervals in the flux limiting plate 303.

In order to facilitate the control of the precise height of the product descent, the height of the flux limiting plate 303 in the flux pool 301 is controlled by the lifting cylinder 302. During the descent of the product, the height of the product is limited by the flux limiting slot 306. In addition, the flux limiting slot 306 can carry part of the flux, and the flux limiting plate 303 can be directly removed from the flux pool 301, and the flux can be dipped through the product and the flux in the flux limiting slot 306.

[0048] In addition, a first shielding plate 304 is provided on one side of the flux pool 301 . When the flux is not needed, the first shielding plate slide rail 305 can be used to drive the first shielding plate 304 to cover the flux pool 301 .

In addition, a second shielding plate 405 and a second shielding plate slide rail 406 are also provided on one side of the tin pool 401, and the second shielding plate slide rail 406 drives the second shielding plate 405 to shield the tin pool 401. A heating rod 404 is provided in the tin pool 401 for heating, and a temperature sensor can also be provided in the tin pool 401 to facilitate temperature control.

[0050] See also Figure 8 The transfer module 8 is arranged adjacent to the automatic electrical testing station 5. The automatic electrical testing station 5 includes an electrical testing cylinder 501, an electrical testing carrier plate 502 and a probe group 503 for electrical testing. The electrical testing carrier plate 502 is arranged at the execution end of the electrical testing cylinder 501. The probe group 503 is vertically arranged on the electrical testing carrier plate 502. The probe group 503 includes a plurality of probes, which correspond one by one to the product positions on the welding rod group 9.

[0051] When the soldering gantry module 7 moves with the welding rod group 9 and completes the soldering flux and tinning operations, the L-shaped fixed rod 704 moves to the transfer module 8 under the action of the horizontal moving slide rail 701 and the longitudinal moving slide rail 702, and the rotating platform 205 of the transfer module 8 rotates the welding rod clamp 207 to the corresponding position, and the welding rod clamp 207 opens outward. After the L-shaped fixed rod 704 moves over the welding rod clamp 207, the welding rod group 9 is directly transferred to the welding rod clamp 207 under the action of the welding rod clamp 207. During the transfer process, the limit cylinder 705 shrinks and moves away from the L-shaped fixed rod 704. After the welding rod clamp 207 clamps the welding rod group 9, the electromagnet 211 is energized to realize that the welding rod clamp 207 fixes the welding rod group 9. At this time, the rotating platform 205 is rotated 180 degrees, and the rotating platform 205 drives the welding rod group 9 after tinning to the automatic electrical measurement station 5. The electric measuring cylinder 501 extends upward, driving the electric measuring carrier plate 502 and the probe group 503 thereon to move upward, so that the probe group 503 contacts the product for electric measuring. After the electric measuring is completed, the electric measuring cylinder 501 contracts downward. At this time, the rotating cylinder 206 rotates 180 degrees with the welding rod group 9, and the product faces upward, and the product is unloaded through the robot unloading module 601.
