Description

Technical Field

[0001] This application relates to the technical field of dispensing machines, and in particular to a dispensing machine for processing thermometer casings. Background Technology

[0002] Currently, in the manufacturing process of thermometer casings, precise adhesive application is required around the button hole on the inner side of the casing to ensure the subsequent sealing and fixing of the button structure. The uniformity and stability of the adhesive application directly determine the assembly accuracy and sealing performance of the thermometer casing. Existing thermometer casing adhesive application equipment has many shortcomings in practical applications.

[0003] Traditional dispensing equipment typically employs a single-station fixed processing structure, capable of dispensing only a small number of workpieces at a time. Furthermore, the workstations cannot be independently controlled, resulting in poor processing flexibility and difficulty in adapting to the batch, continuous dispensing needs of thermometer shells, leading to low production efficiency. In addition, most dispensing equipment relies heavily on manual unloading, resulting in low automation. After dispensing, workers must individually remove the workpieces from the limiting station, which is not only labor-intensive and inefficient, but also prone to contact with uncured adhesive, causing adhesive contamination, workpiece displacement, and adhesive layer damage, easily resulting in defective products. Utility Model Content

[0004] This application provides a dispensing machine for processing thermometer shells, which features independent operation of two workstations, significantly improving production efficiency, automating unloading and material collection, and reducing labor costs and workpiece damage.

[0005] The application provides a dispensing machine for processing thermometer shells, which adopts the following technical solution: A dispensing machine for processing thermometer shells includes a base, a linear guide rail on the base, and a multi-axis motion module mounted on top of the linear guide rail; a dispensing module is mounted on the multi-axis motion module; two sets of linear guide rails are provided, a material placement seat is provided at the moving end of the linear guide rail, a plurality of limiting grooves for placing workpieces are sequentially provided on the material placement seat, and an unloading module is provided at the fixed end of the linear guide rail, the unloading module including a lifting unloading plate; the material placement seat has an unloading slot for inserting the unloading plate into the lower part of the limiting groove, and the unloading plate is used to synchronously remove the workpiece from its respective limiting groove.

[0006] Preferably, the unloading module further includes a fixed seat mounted on the fixed end of the linear guide rail, and an unloading cylinder is provided on the fixed seat. The piston rod of the unloading cylinder is connected to the unloading plate provided on the fixed seat. The unloading cylinder is used to drive the unloading plate to move up and down along the height direction of the fixed seat.

[0007] Preferably, the fixed base is further provided with a clamping plate located above the unloading plate, and the clamping plate is arranged opposite to the unloading plate; the unloading plate moves up and down in the direction of approaching or moving away from the clamping plate, and the clamping plate and the unloading plate are used to clamp and fix the workpiece taken out from the limiting groove.

[0008] Preferably, the clamping plate has a limiting member on its side wall facing the unloading plate. The limiting member is used to be inserted into the support of the workpiece, and the shape of the limiting member is adapted to the shape of the support. The unloading plate has a clearance hole corresponding to the limiting member. The clearance hole is used to allow the corresponding limiting members to be inserted into the unloading plate.

[0009] Preferably, the fixed base is provided with a guide rod, and the unloading plate is movably inserted through the guide rod.

[0010] Preferably, a buffer pad is fitted around the outside of the guide rod.

[0011] Preferably, the machine base is also equipped with a support frame corresponding to each set of linear guide rails, and a receiving tray is slidably installed on the support frame. The receiving tray is used to move into or out of the unloading plate.

[0013] In summary, this application includes at least one of the following beneficial technical effects: The two sets of linear guides do not interfere with each other, can be started and stopped independently, and have independent speed adjustment, enabling synchronous or staggered completion of thermometer shell dispensing operations, thus improving the low processing efficiency of traditional single-station equipment. At the same time, the material placement seat is equipped with multiple spaced contour-guided limiting grooves, which can place multiple workpieces at one time, realizing batch continuous dispensing processing, greatly improving the overall production capacity of thermometer shell dispensing processing, and adapting to the needs of large-scale production; The limiting groove, whose shape matches the workpiece's outline, can limit and fix the workpiece in all directions, effectively preventing the workpiece from shifting or shaking during the dispensing process, ensuring accurate dispensing position and uniform adhesive layer around the button hole, and eliminating quality problems such as overflowing adhesive, insufficient adhesive, and off-center adhesive. It achieves automated unloading of workpieces, eliminating the need for manual picking and picking, significantly reducing the labor intensity of workers and improving unloading efficiency. After unloading, the workpiece can be quickly received by a sliding receiving tray, thereby reducing the probability of manual contact with the uncured adhesive layer, reducing the occurrence of problems such as adhesive contamination, adhesive layer damage, and workpiece collision, and ensuring the curing effect.

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] This application discloses a dispensing machine for processing thermometer shells.

[0018] Reference Figure 1 , Figure 2 The thermometer casing dispensing machine includes a base 1, on which two sets of linear guide rails 2 are movably mounted, symmetrically arranged on the left and right sides of the base 1. A gantry frame 10 is also fixedly mounted on the base 1. A multi-axis motion module 3, mounted on top of the linear guide rails 2, is installed on the gantry frame 10. The multi-axis motion module 3 includes an X-axis slide 30 that reciprocates horizontally, and a Z-axis slide 31 movably mounted on the X-axis slide 30. The Z-axis slide 31 reciprocates vertically, and a dispensing module 4 is mounted on the Z-axis slide 31. A controller 100 is also installed on the gantry frame 10 to control the movement of the X-axis slide 30, the Z-axis slide 31, and the linear guide rails 2.

[0019] The controller 100 may include a central processing unit such as a CPU or MPU, or a host system built around a CPU or MPU, including hardware or software. Users can freely control these modules through programming, making them operate according to their wishes. It can also control local data transfer / traceability components, remote data transfer / traceability components, and remote communication components through internal protocols. Internal protocols may include some or all of the following protocols: human-machine interface protocols, software / hardware (interface) protocols, chip bus (C-Bus) protocols, and internal bus (I-Bus) protocols. With the development of integrated circuit technology, some protocols that belong to external bus (E-Bus) have also become internal protocols after being integrated into the chip along with the external bus (E-Bus).

[0020] The controller 100 simultaneously sends pulse commands to the drivers of the X-axis slide 30, Z-axis slide 31, and linear guide 2 according to the preset dispensing path. The linear guide 2 serves as the Y-axis, with the machine origin as the coordinate system (0,0,0). Each dispensing position in the program corresponds to a set of (X,Y,Z) coordinate values. The controller 100 precisely controls the movement distance by controlling the number of pulses for each axis and controls the movement speed by controlling the pulse frequency. The control logic and working principle of the multi-axis motion module 3 and the linear guide 2 are well-known technologies to those skilled in the art and will not be elaborated further.

[0021] like Figure 2 , Figure 3 As shown, the dispensing module 4 mainly includes a pressure tank, a dispensing valve, and a pneumatic control system. The adhesive is stored in the pressure tank. The pneumatic control system is connected to the inside of the pressure tank via an air pipe, continuously applying pressure to the adhesive in the pressure tank using compressed air to give it flow power. The opening and closing of the dispensing valve is controlled by the electrical signal output by the controller 100. When the dispensing valve opens, the air pressure pushes the adhesive in the pressure tank to flow out from the nozzle at the bottom of the pressure tank. When the dispensing valve closes, the dispensing immediately stops. The control logic and working principle of the dispensing module 4 are well-known technologies to those skilled in the art and therefore will not be described in detail.

[0022] like Figure 1 , Figure 2 As shown, a material placement seat 5 is detachably mounted and fixed to the moving end of the linear guide rail 2 by fasteners. Multiple limiting grooves 50 for placing workpieces are sequentially arranged on the upper surface of the material placement seat 5, with each limiting groove 50 evenly spaced along the sliding direction of the material placement seat 5. An unloading module 6 is provided at the fixed end of the linear guide rail 2, which is used to synchronously remove the workpieces from the limiting grooves 50.

[0023] like Figure 2 , Figure 4As shown, the unloading module 6 includes a fixed base 61 that is detachably mounted and fixed to the fixed end of the linear guide rail 2. An unloading plate 60 is vertically mounted on the fixed base 61, and the length of the unloading plate 60 extends horizontally towards its respective material placement seat 5. An unloading cylinder 62 is mounted on the top of the fixed base 61. The piston rod of the unloading cylinder 62 is connected and fixed to the unloading plate 60, and the unloading cylinder 62 is used to drive the unloading plate 60 to move up and down along the height direction of the fixed base 61.

[0024] like Figure 2 , Figure 4 As shown, guide rods 66 are fixedly installed on the fixed base 61, located on both sides of the piston rod of the unloading cylinder 62. The length of the guide rods 66 is set along the lifting direction of the piston rod of the unloading cylinder 62. The unloading plate 60 is movably mounted on the guide rods 66. A buffer pad 67 is fixedly sleeved on the outside of the guide rods 66, which is in contact with the inner sidewall of the fixed base 61. The buffer pad 67 is made of rubber with elastic deformation capability. When the unloading plate 60 moves to the point of contacting the buffer pad 67, the buffer pad 67 can prevent the unloading plate 60 from directly contacting the inner sidewall of the fixed base 61, thereby providing buffer protection for the unloading plate 60.

[0025] like Figure 2 , Figure 3 , Figure 4 As shown, the material placement base 5 has an unloading slot 51 for the unloading plate 60 to be inserted horizontally into the lower limit groove 50. The unloading slot 51 is connected to the upper limit groove 50. The workpiece, which is placed horizontally in the limit groove 50, is mounted above the unloading slot 51, and the length direction of the workpiece is perpendicular to the length direction of the unloading slot 51. The width of the unloading slot 51 is adapted to the width of the unloading plate 60, which is used to simultaneously remove the workpiece from its respective limit groove 50 from bottom to top. A clamping plate 63 is also fixedly installed on the outer wall of the fixing base 61 facing the material placement base 5, located directly above the unloading plate 60. The clamping plate 63 is arranged opposite to the unloading plate 60.

[0026] like Figure 2 , Figure 3 , Figure 4 As shown, the unloading plate 60 is moved up and down towards or away from the clamping plate 63 under the drive of the unloading cylinder 62. The clamping plate 63 and the unloading plate 60 are used to clamp and fix the workpiece taken out from the limiting groove 50. Limiting members 64 are fixedly provided on the side wall of the clamping plate 63 facing the unloading plate 60. The limiting members 64 are arranged evenly at intervals along the length of the clamping plate 63.

[0027] like Figure 2 , Figure 4As shown, when the unloading plate 60 inserted in the unloading slot 51 reaches the designated position, the limiting members 64 will correspond to the workpieces in the limiting slots 50. The shape of the limiting member 64 is adapted to the shape of the bracket on the workpiece. The bracket, integrally formed on the workpiece, is used to install the mirror of the thermometer, and the bracket limits the mirror within the housing. As the unloading plate 60 lifts the workpieces in the limiting slots 50 upward, the limiting members 64 will be inserted into the brackets of the workpiece from top to bottom until the limiting members 64 protrude from the outer side wall of the workpiece. The unloading plate 60 has through-holes 65 that correspond one-to-one with each limiting member 64, and the through-holes 65 are used to allow the limiting members 64 to be inserted into the unloading plate 60.

[0028] Two sets of linear guides 2 operate independently, can be started and stopped separately, and have their speeds adjusted independently. They can complete the dispensing operation of thermometer shells synchronously or at off-peak times, improving the low processing efficiency of traditional single-station equipment. Meanwhile, the material holder 5 is equipped with multiple spaced contour-guided limiting grooves 50, allowing multiple workpieces to be placed at once, achieving batch continuous dispensing processing. This greatly increases the overall production capacity of thermometer shell dispensing and adapts to the needs of large-scale production. The limiting grooves 50, whose shape matches the workpiece's outline, can omnidirectionally limit and fix the workpiece, effectively preventing workpiece displacement and shaking during dispensing. This ensures accurate dispensing position and uniform adhesive layer around the button hole, eliminating quality problems such as overflow, insufficient adhesive, and uneven adhesive application.

[0029] After the button assembly of the workpiece on the placement seat 5 is completed, the placement seat 5 is moved closer to the unloading module 6 until the unloading plate 60 is fully inserted into the unloading slot 51. Then, the unloading cylinder 62 is controlled to drive the unloading plate 60 upward, at which point the unloading plate 60 pushes each workpiece to move upward synchronously from its respective limiting slot 50. As the workpiece height continues to rise, the limiting members 64 are inserted into the workpiece's support, limiting each workpiece and effectively preventing it from falling off the unloading plate 60. Finally, the workpiece is clamped and fixed between the clamping plate 63 and the unloading plate 60. Then, the placement seat 5 is moved away from the unloading module 6, at which point the workpiece can be smoothly separated from the placement seat 5. This achieves automated unloading, eliminating the need for manual picking and picking of workpieces, significantly reducing the labor intensity of workers and improving unloading efficiency.

[0030] like Figure 1 , Figure 3As shown, support frames 7 corresponding to each set of linear guide rails 2 are fixedly installed on the left and right sides of the base 1. A track 71 is horizontally fixedly installed on the upper surface of the support frame 7, and the length direction of the track 71 is perpendicular to the length direction of the linear guide rail 2. A receiving tray 70 is slidably installed on the track 71 in the horizontal direction. The receiving tray 70 is used to move into or out from under its respective discharge plate 60. The receiving tray 70 slides and is limited on the track 71. A limiting post 72 is detachably fixed to the bottom of the receiving tray 70 by a thread. The limiting post 72 is used to prevent the receiving tray 70 from detaching from the track 71. When the limiting post 72 moves with the receiving tray 70 to contact the outer wall of the support frame 7, the receiving tray 70 will be limited on the track 71 by the limiting post 72. When it is necessary to remove the receiving tray 70 from the track 71, the receiving tray 70 can be smoothly removed from the track 71 by unscrewing the limiting post 72 from the bottom of the receiving tray 70.

[0031] The implementation principle is as follows: Two sets of linear guides 2 operate independently, can be started and stopped separately, and have independent speed adjustments, enabling synchronous or staggered completion of thermometer shell dispensing operations, thus overcoming the low processing efficiency of traditional single-station equipment. Simultaneously, the material placement seat 5 is equipped with multiple spaced contour-guided limiting grooves 50, allowing for the placement of multiple workpieces at once, achieving batch continuous dispensing processing. This significantly increases the overall production capacity of thermometer shell dispensing, adapting to the needs of large-scale production. The limiting grooves 50, whose shape matches the workpiece's outline, can omnidirectionally limit and fix the workpiece, effectively preventing workpiece displacement and shaking during dispensing, ensuring precise dispensing position and uniform adhesive layer around the button hole, and eliminating quality problems such as overflow, insufficient adhesive, and uneven adhesive application.

[0032] This system automates workpiece unloading, eliminating the need for manual picking and picking, significantly reducing labor intensity and improving unloading efficiency. After unloading, the sliding receiving tray 70 quickly receives the workpiece, reducing the probability of manual contact with the uncured adhesive layer, minimizing adhesive contamination, adhesive layer damage, and workpiece impacts, thus ensuring optimal curing results.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
