Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a workstation switching device. Background Technology

[0002] Existing circumferential carriers typically have multiple stations. A drive unit rotates the carrier by a specified angle to switch between stations one by one, facilitating the feeding of parts at each station. When a station on the carrier is in the feeding zone, the parts at that station are being processed, and these parts exert a downward force on the carrier. Due to the unbalanced force on the carrier, it is easy for the carrier to tilt, affecting its lifespan.

[0003] For example, the existing Chinese patent application, with authorization announcement number CN215709965U, is titled "A Carrier Positioning Device," comprising a base plate, a cam divider, a turntable, a fixed plate, a pressing mechanism, and a carrier mechanism. The cam divider is fixed to the base plate and drives the turntable to rotate. Multiple detection stations are evenly distributed around the circumference of the turntable. The fixed plate is fixed to the housing of the cam divider, coaxially arranged with the turntable, and located above the turntable. The carrier mechanism includes a carrier plate, a positioning seat, and a support seat. The positioning seat is connected to the upper end of the support seat via a floating mechanism. The positioning seat has a placement cavity adapted to the carrier plate, which is held in place. The support seat is positioned within the detection stations. The pressing mechanism is located on the fixed plate and is used to press down the positioning seat. While this solution allows for station switching, it presents a problem of turntable tilting when used for processing parts at the stations.

[0004] In summary, the technical problem that this application needs to solve is: how to prevent the carrier disk from tilting due to uneven force. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a workstation switching device. This solution supports the carrier by setting a clamping component. Pressure contact occurs between the clamping component and the support component, forming effective support for the carrier, thereby counteracting the downward tilt of the carrier.

[0006] Specifically, this utility model proposes a workstation switching device, including a cabinet, a drive assembly, a carrier plate, a clamping assembly, and a support assembly.

[0007] The carrier tray is mounted on the cabinet via a drive assembly. The upper surface of the carrier tray is provided with a workstation for mounting parts. The drive assembly has a drive shaft for rotating the carrier tray.

[0008] The support assembly is fixed to the cabinet and is located below the tray;

[0009] A clamping assembly is fixed to the lower surface of the carrier plate and is used to make pressure contact with the top surface of the support assembly.

[0010] Preferably, there are multiple workstations on the carrier plate, and the number of the clamping components is the same as the number of workstations.

[0011] Preferably, each of the clamping components includes two elastic clamps, and the vertical projection of the mounting platform on the workstation is located between the two elastic clamps.

[0012] Preferably, the support assembly includes a support platform and rollers, with two rollers respectively mounted on the support platform via mounting bases 38, and the rollers are used to support the lower end of the elastic extruder.

[0013] Preferably, the elastic extrusion member includes a sleeve, a spring, and an extrusion plate. The sleeve is fixed to the carrier plate, and the lower end of the sleeve is fixed to the extrusion plate by the spring. The extrusion plate is used to extrude the roller.

Detailed Implementation

[0025] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0026] like Figures 1 to 5 As shown, this embodiment proposes a workstation switching device, including a cabinet 11, a drive assembly 12, a carrier tray 13, a clamping assembly 14, and a support assembly 15.

[0027] The tray 13 is mounted on the cabinet 11 via the drive assembly 12. The upper surface of the tray 13 is provided with a workstation for mounting parts. The drive assembly 12 has a drive shaft for rotating the tray 13.

[0028] The support assembly 15 is fixed to the cabinet 11 and is located below the tray 13;

[0029] The clamping component 14 is fixed to the lower surface of the carrier plate 13 and is used to make pressure contact with the top surface of the support component 15.

[0030] This solution supports the carrier plate 13 by setting a clamping component 14. The clamping component 14 and the support component 15 make pressure contact, forming an effective support for the carrier plate 13, thereby counteracting the downward tilt of the carrier plate 13.

[0031] The drive assembly 12 in this solution includes a motor 24, a reducer 25, a drive wheel 26, a timing belt 27, a driven wheel 28, and an indexer 29.

[0032] Among them, the input shaft of the indexer 29 is fixed with a driven wheel 28, and the output shaft of the indexer 29 is used to fix and support the carrier disk 13. The output shaft of the indexer 29 is also the drive shaft of the drive assembly 12.

[0033] A reducer 25 is mounted on the output shaft of the motor 24. The motor 24 and the reducer 25 can be a separate structure or an integrated geared motor structure.

[0034] The drive wheel 26 is fixed on the output shaft of the reducer 25, and the drive wheel 26 and the driven wheel 28 are connected by a synchronous belt 27.

[0035] The indexer 29 is existing technology, and its structure and working principle will not be described in detail in this solution.

[0036] In addition, the drive component 12 in this solution can also adopt other structures, such as a rotary cylinder or a geared motor for driving.

[0037] As one implementation of this embodiment, there are multiple workstations on the carrier 13, and the number of clamping components 14 is the same as the number of workstations.

[0038] Furthermore, the stations on the carrier tray 13 are the initial station 30, the feeding station 31, the inspection station 32, and the unloading station 33. Each station is equipped with an installation platform 17.

[0039] At the initial station 30, the larger main part 34 is placed on the mounting table 17. Then, the carrier tray 13 rotates 90° counterclockwise, and the carrier tray 13 carries the main part 34 into the feeding station 31. The robot arm installs the matching, smaller part 35 onto the larger main part 34. At this time, at the feeding station 31, the carrier tray 13 will be subjected to downward pressure. With the support of the support assembly 15 and the clamping assembly 14, the tilting of the carrier tray 13 is effectively prevented.

[0040] Multiple photoelectric sensors 36 are installed on the inspection station 32.

[0041] A material bin 37 is provided at the unloading station 33. The robotic arm puts the products from the unloading station 33 into the material bin 37.

[0042] Each clamping component 14 includes two elastic clamping members 16, and the vertical projection of the mounting platform 17 on the workstation is located between the two elastic clamping members 16.

[0043] Since there are four workstations, each workstation will enter the feeding area. At this time, the workstation is converted into a feeding workstation 31. Therefore, two elastic extrusion members 16 are set directly below each workstation to facilitate effective support of the carrier plate 13.

[0044] The support component 15 is a single component to save costs. When the part on the carrier plate 13 is at the feeding station 31, the clamping component 14 under the part automatically docks with the support component 15.

[0045] Alternatively, the number of support components 15 can be set to multiple.

[0046] The support assembly 15 includes a support platform 18 and rollers 19. The two rollers 19 are respectively mounted on the support platform 18 via mounting bases 38. The rollers 19 are used to support the lower end of the elastic extrusion member 16. There is a one-to-one correspondence between the two rollers 19 and the two elastic extrusion members 16.

[0047] Furthermore, the support platform 18 includes a fixing plate 39 and a fixing column 40. A mounting base 38 is fixed on the fixing plate 39, and the lower end of the fixing plate 39 is welded to the cabinet 11 through the fixing column 40.

[0048] As one embodiment of this example, the elastic extrusion member 16 includes a sleeve 20, a spring 21, and an extrusion plate 22. The sleeve 20 is fixed in the mounting hole of the carrier plate 13 by means of screws or welding. The lower end of the sleeve 20 is fixed with the extrusion plate 22 by the spring 21. The extrusion plate 22 is used to extrude the roller 19.

[0049] The advantage of using roller 19 in this scheme is that, since the circumferential surface of roller 19 is curved, when the extrusion plate 22 is in direct contact with the curved surface, the curved surface will guide the extrusion plate 22. At this time, the spring 21 is compressed and deformed, and the extrusion plate 22 is gradually pressed onto the top of roller 19.

[0050] Furthermore, the axis of roller 19 is arranged radially along the carrier disk 13, that is, the axis of roller 19 is arranged at a right angle to the axis of carrier disk 13, in order to improve the rotation effect of roller 19.

[0051] Furthermore, the extrusion plate 22 is slidably disposed in the inner hole of the sleeve 20 in the vertical direction via the guide rod 23.

[0052] As one embodiment of this example, the projection of the extrusion plate 22 in the vertical direction is circular.

[0053] Furthermore, the lower end face of the extrusion plate 22 is curved. This is used to improve the bonding efficiency between the extrusion plate 22 and the roller 19.

[0054] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
