Placement machine is widely used in the electronic manufacturing industry, especially in the assembly process of electronic components in the fields of mobile phones, computers, communication equipment, automotive electronics, etc. Placement machine uses visual system and precise mechanical structure to take out the placement auxiliary materials from the feeder and accurately fit them to the electronic components, and then enter the next process. Placement machine is mainly used to place various electronic manufacturing auxiliary materials. Placement machine usually includes components such as feeder, transmission system, visual recognition system, placement head, control system, etc. The visual recognition system is used to accurately locate auxiliary materials and electronic components to ensure the accuracy of placement; the placement head is responsible for taking auxiliary materials from the feeder and accurately fitting them to the electronic components.

Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0024] Reference Figures 1 to 7 As shown, the utility model discloses a double gantry placement machine, specifically, the device includes a frame 10, a beam assembly 20, a lifting assembly 30, a placement head assembly 40 and a track assembly 50. The lifting assembly 30 is arranged on the platform of the frame 10, and the lifting assembly 30 is used to lift the product. The lifting assembly 30 is connected to the track assembly 50, and the lifting assembly 30 can slide along the length direction of the beam assembly 20 on the track assembly 50. Two groups of beam assemblies 20 are arranged above the lifting assembly 30, and the placement head assembly 40 is arranged on the beam assembly 20. The placement head assembly 40 is used to place the product lifted by the lifting assembly 30.

[0025] Specifically, the lifting assembly 30 includes a lifting motor 301, a motor mounting plate 302, and a lifting guide shaft 303. The motor mounting plate 302 is installed between the track assemblies 50, and the motor mounting plate 302 can slide along the track assemblies 50. The lifting motor 301 is installed on the motor mounting plate 302, and the lifting guide shaft 303 is also installed around the motor mounting plate 302. The lifting guide shaft 303 is used to fix the position of the product; when the lifting guide shaft 303 fixes the position of the product, it moves toward the direction of the mounting head assembly 40 under the drive of the lifting motor 301, so that the mounting head assembly 40 can mount the product.

[0026] Specifically, the track assembly 50 includes a track 501 and a screw rod 502. Two tracks 501 are provided, and a screw rod 502 is provided between the two tracks 501. The distance between the two tracks 501 can be adjusted by the screw rod 502. By adjusting the distance between the tracks 501, products of different sizes can be accommodated. Because the track assembly 50 is a technology commonly used by those skilled in the art, the structure of the track assembly 50 is not described in detail.

[0027] Specifically, the beam assembly 20 includes a beam frame 201, a driving screw 202, a screw driving motor 203, a mounting head mounting plate 204 and a connecting block 205; the screw driving motor 203 is fixed on the beam frame 201 through a mounting seat, the driving end of the screw driving motor 203 is connected to the driving screw 202, and the driving screw 202 is connected to the mounting head mounting plate 204 through the connecting block 205. A slide rail is provided on the beam frame 201, and the connecting block 205 is connected to the slide rail. The driving screw 202 is driven to rotate by the screw driving motor 203, and because the driving screw 202 is connected to the mounting head mounting plate 204 through the connecting block 205, the mounting head mounting plate 204 can slide on the slide rail of the beam frame 201 under the drive of the screw driving motor 203.

[0028] The placement head assembly 40 is connected to the beam assembly through the placement head mounting plate 204, and the placement head assembly 40 includes a placement head base plate 401, a placement head Z-axis module 402, a placement head R-axis module 403, a camera 404 and a light source 405; a placement head Z-axis module 402 is arranged on the placement head base plate 401, and the placement head Z-axis module 402 is connected to the placement head R-axis module 403; the placement head Z-axis module 402 and the placement head R-axis module 403 are each arranged in two groups, which are connected to the placement head R-axis module 403 through the placement head Z-axis module 402, and then the placement head Z-axis module 402 and the placement head R-axis module 403 are arranged on both sides of the placement head base plate 401, wherein the placement of the product is realized through the placement head R-axis module 403. A camera 404 is arranged between the two groups of mounting head R-axis modules 403, a light source 405 is arranged below the camera 404, and the lens of the camera 404 is arranged opposite to the light source 405, and the action process of photo positioning - material picking - photo correction - bonding is realized by the camera 404 and the light source 405.

[0029] A slide rail is also provided on the mounting head bottom plate 401, and the mounting head R-axis module 403 can move along the slide rail toward the product. A pressure feedback module 406 is also provided at the end of the mounting head R-axis module 403 (i.e., the end that is bonded to the product), and the pressure feedback module 406 is used to control the bonding height of the product. Specifically, the pressure feedback module 406 includes a pressure sensor 4061, a spring 4062, and a suction nozzle 4063. The pressure sensor 4061 is connected to the mounting head R-axis module 403, the spring 4062 is connected to the pressure sensor 4061, and the suction nozzle 4063 is connected to the spring 4062. When the mounting head R-axis module 403 is bonded to the product, the suction nozzle 4063 is subjected to force through the downward pressure of the mounting head Z-axis module 402, and the force received by the suction nozzle 4063 is transmitted to the pressure sensor 4061 through the spring 4062. After the control system in the double gantry mounting machine reads the pressure value, it performs a real-time control on the bonding height.

[0030] Two groups of beam assemblies 20 are arranged in parallel on the frame 10, and the spacing between the two groups of beam assemblies 20 is adjustable. When there are products of different sizes, the spacing between the two groups of beam assemblies 20 can be adjusted according to the size of the products to achieve product placement. The driving screw 202 can be driven to rotate by the screw drive motor 203 in the beam assembly 20. Because the driving screw 202 is connected to the mounting head mounting plate 204 through the connecting block 205, the mounting head mounting plate 204 can slide on the slide rail of the beam frame 201 under the drive of the screw drive motor 203, and the mounting head assembly 40 can also be driven to move along the length direction of the beam assembly 20. In order to achieve product placement.
