Description

Technical Field

[0001] The invention belongs to the technical field of preparing coffee beverages, and in particular relates to an assembly device and an assembly processing method for a coffee grinder. Background Art

[0002] As global coffee consumption continues to grow, consumers' requirements for coffee quality are also increasing. Freshly ground coffee is becoming more and more popular among consumers because it can provide higher freshness and richer taste levels. Therefore, whether it is a professional coffee shop or a home user, a high-quality coffee grinder has become an indispensable tool. Currently, coffee grinders on the market can be divided into two categories: blade type and disc type. Blade type grinders are limited in their application in the professional field because of their uneven grinding and the heat generated during the grinding process may change the original flavor of the coffee beans. In contrast, disc grinders dominate the professional coffee field with their excellent grinding accuracy and good temperature control capabilities.

[0003] Although the burr grinder has obvious advantages, the traditional manual assembly method is not only inefficient, but also difficult to ensure that the assembly quality of each machine meets high standards. For this reason, manufacturers have launched assembly equipment for the assembly of coffee grinders, but there are the following problems in actual application:

[0004] First, the problem of loading efficiency; currently most assembly equipment uses a single linear reciprocating mechanism to complete the loading of grinder workpieces. Since this mechanism needs to complete a complete back and forth motion to complete one loading, its loading speed is limited. In order to solve this problem, some assembly manufacturers have adopted a cyclic reciprocating system consisting of two linear reciprocating mechanisms, and increased the loading rate by alternating the two mechanisms. However, since the feed port and the discharge port of the two linear reciprocating mechanisms cannot be precisely aligned, the position of the feeding port will change during alternating loading, which increases the complexity of workpiece positioning and affects the continuity and stability of the loading process, thereby reducing the overall assembly efficiency.

[0005] Secondly, there is the problem of collision. In order to ensure that the inlet and outlet of the two linear reciprocating mechanisms are aligned as much as possible, these mechanisms are usually set very close to each other. This leads to easy collision between workpieces during assembly, especially for key components such as grinding discs. Once a collision occurs, it may cause surface damage, which not only affects the performance and grinding quality of the grinder, but also may bring safety risks.

[0006] Finally, the problem of center positioning: Due to the change in the position of the feed port, it is difficult to accurately position the core workpieces such as the grinding disc during assembly. If the center position of the grinding disc is inaccurate, it will cause uneven grinding of the coffee grinder after assembly, which will directly affect the quality of the coffee. In addition, inaccurate center positioning will also aggravate the problem of collision between workpieces, further affecting the assembly quality and the safety of the equipment.

[0030] Embodiment 1

[0031] See also Figure 1An assembly device includes a feeding mechanism 1, wherein the feeding mechanism 1 includes: a driving component 11, wherein the driving component 11 has a dual output end, and the dual output end design enables the driving component 11 to continuously drive the clamp 2 to perform cyclic reciprocating motion, thereby achieving continuous feeding, thereby improving the overall feeding efficiency. A mounting block 12 is provided at the output end of the driving component 11, and the mounting block 12 is slidably provided with a clamp 2, and the sliding direction of the clamp 2 on the mounting block 12 is perpendicular to the output direction of the driving component 11; that is, the moving direction of the clamp 2 forms a right angle with the power output direction of the driving component 11, and such a design helps to improve the flexibility and stability during the feeding process. The limiting track 13 is located above the driving component 11. The limiting track 13 is arranged in a ring shape. The limiting track 13 is used to constrain the sliding position of the clamp 2 on the mounting block 12. The limiting track 13 can constrain the sliding position of the clamp 2 on the mounting block 12, ensuring that the clamp 2 always remains on the correct path during the cyclic reciprocating feeding process, thereby avoiding the workpiece from being bumped or shifted in position during the feeding process. The use of the limiting track 13 helps to improve the accuracy of the feeding process and ensure the position accuracy of the workpiece during the assembly process. The cyclic reciprocating feeding of the assembly equipment is realized by setting the dual output ends of the driving component 11; the limiting track 13 constrains the sliding position of the clamp 2 on the mounting block 12 to avoid bumping during the cyclic reciprocating feeding process.

[0032] Specifically, the driving component 11 starts working, and one of the output ends pushes the mounting block 12 and the fixture 2 to move along the limiting track 13; the fixture 2 slides along the mounting block 12 under the constraint of the limiting track 13, and the fixture 2 clamps the workpiece and delivers the workpiece to the specified position as the mounting block 12 moves. When one output end completes the action, the other output end starts working, causing the mounting block 12 to move in the opposite direction, thereby realizing a cyclical loading process. The design of the limiting track 13 ensures that the fixture 2 will not deviate from the predetermined trajectory during the movement, effectively avoiding collisions between workpieces.

[0033] See also Figure 2 , 3The driving assembly 11 includes a first chamber 111 and a second chamber 112 which are arranged in parallel. The opening directions of the first chamber 111 and the second chamber 112 are the same. The first piston rod 113 and the second piston rod 114 are slidably arranged at the openings of the first chamber 111 and the second chamber 112 respectively. The front ends of the first piston rod 113 and the second piston rod 114 are provided with the mounting block 12. An oil pump is arranged between the first chamber 111 and the second chamber 112; the oil pump is used to control the flow direction of the liquid in the chamber. When the oil pump directs the liquid in the first chamber 111 into the second chamber 112, the first piston rod 113 will contract and the second piston rod 114 will extend; when the oil pump directs the liquid in the second chamber 112 into the first chamber 111, the first piston rod 113 will extend and the second piston rod 114 will contract; the oil pump controls the reciprocating motion of the first piston rod 113 and the second piston rod 114, and enables the first piston rod 113 and the second piston rod 114 to achieve reciprocating feeding.

[0034] Specifically, initially, it is assumed that the first piston rod 113 is in an extended state and the second piston rod 114 is in a retracted state; when the oil pump directs the liquid in the first chamber 111 into the second chamber 112, the pressure in the first chamber 111 decreases, and the first piston rod 113 begins to retract; at the same time, the pressure in the second chamber 112 increases, and the second piston rod 114 begins to extend. When the first piston rod 113 is fully retracted and the second piston rod 114 is fully extended, the clamp 2 on the mounting block 12 completes a feeding action. Next, the oil pump directs the liquid in the second chamber 112 back into the first chamber 111, causing the second piston rod 114 to begin to retract and the first piston rod 113 to begin to extend, completing a cyclic reciprocating action. This process is repeated continuously, so that the first piston rod 113 and the second piston rod 114 alternately extend and retract, realizing continuous cyclic reciprocating feeding. Through the design of the double chamber and the control of the oil pump, a continuous cyclic reciprocating feeding process is realized, and the feeding efficiency is improved. The parallel dual chamber and piston rod structure ensures the stability of the loading process and reduces the collision of the workpiece during the loading process. The oil pump can accurately control the flow direction of the liquid, thereby accurately controlling the telescopic action of the piston rod, ensuring the accuracy of the loading process.

[0035] See also Figure 4The clamp 2 includes a base 21, and movable blocks 22 are slidably provided at both ends of the base 21. The movable block 22 has an installation chamber 23, and the opening of the installation chamber 23 faces upward. A clamping rod 24 that can slide along the side wall of the installation chamber 23 is provided in the installation chamber 23, and an elastic limiting belt is installed on the clamping rod 24; the elastic limiting belt should be made of wear-resistant, high-temperature resistant, and elastic materials, such as silicone, Teflon, etc. The elastic limiting belt ensures the stability and safety of the workpiece during the clamping process. By adjusting the spacing between the movable blocks 22, the spacing of the clamping rod 24 can be moved over a large range, thereby clamping workpieces of different specifications; by adjusting the spacing between the movable blocks 22 and the clamping rod 24, the clamp 2 can adapt to workpieces of various sizes and shapes. By adjusting the spacing between the clamping rods 24 on the movable blocks 22, the clamping rods 24 control the limiting belt to cover and fix the workpiece.

[0036] Specifically, the spacing between the movable blocks 22 is adjusted manually or automatically to accommodate workpieces of different sizes; this adjustment mechanism can be threaded adjustment, hydraulic adjustment, or any other suitable method. The spacing between the clamping rods 24 on the movable blocks 22 can also be adjusted according to the size of the workpiece to ensure that the workpiece can be stably clamped; this adjustment mechanism can be adjusted by a telescopic cylinder. After the spacing between the movable blocks 22 and the spacing between the clamping rods 24 are adjusted, the clamp 2 moves to the workpiece, the clamping rod 24 moves, and the elastic limiting belt unfolds to cover and fix the workpiece. When the workpiece is sent to the designated position for assembly, the clamping rod 24 retracts, the elastic limiting belt is loosened, and the workpiece is released.

[0037] See also Figure 4 The clamp rod 24 is retractably arranged in the installation chamber 23, and the clamp 2 can switch between the feeding state and the assembly state according to the extension and retraction of the clamp rod 24; when the clamp rod 24 is extended, the clamp 2 is in the feeding state; when the clamp rod 24 is retracted, the clamp 2 is in the assembly state, avoiding the influence of the clamp rod 24 on the assembly.

[0038] Specifically, the spacing adjustment of the movable block 22 can be achieved by thread adjustment, hydraulic adjustment or any other suitable method, the spacing adjustment of the clamping rod 24 on the movable block 22 can be achieved by telescopic cylinder adjustment, and the telescopic adjustment of the clamping rod 24 in the installation chamber 23 can be achieved by setting a lifting plate controlled by a telescopic cylinder at the bottom of the installation chamber 23, and installing the clamping rod 24 and its spacing adjustment drive device on the lifting plate.

[0039] See also Figure 1 , 4, the feeding mechanism 1 also includes an arranging feeding belt, a swing frame and a baffle. The arranging feeding belt is located above the clamp 2, and is used to arrange the workpieces to be assembled in order and transport them to the designated position. The swing frame is arranged at the front end of the arranging feeding belt, and the baffle is located at the front end of the swing frame, and is used to prevent the workpiece from sliding forward and ensure that the workpiece remains stable in the swing frame. The swing frame includes a bottom support and a side wall. The bottom support is used to support the workpiece, and one end of the side wall is swingably arranged at the front end of the arranging feeding belt; by the combined use of the arranging feeding belt, the swing frame and the baffle, the workpiece can be efficiently transported to the clamping position of the clamp 2; the swing frame setting can facilitate the clamp 2 to clamp the workpiece from the bottom and move it out from the side by moving. A lifting platform 25 is provided between the base 21 and the mounting block 12, which is used to lift the clamp 2 to a suitable height so that the clamp 2 can clamp the workpiece in the swing frame. The clamp 2 is in a feeding state, and the lifting platform 25 lifts the clamp 2 to allow the clamp 2 to clamp the workpiece in the swing frame; when the clamp 2 moves along the limiting track 13, the swing frame will swing with the movement of the clamp 2.

[0040] Specifically, the workpiece is placed on the arrangement feeding belt and is initially positioned by the swing frame and the baffle; when the clamp 2 is in the feeding state, the lifting platform 25 lifts the clamp 2 to the height of the swing frame, the clamp 2 extends into the swing frame, the clamp rod 24 extends and uses the elastic limit belt to cover and fix the workpiece; the clamp 2 moves along the limit track 13, drives the swing frame to swing, and transports the workpiece from the arrangement feeding belt to the assembly area; after arriving at the assembly area, the clamp 2 enters the assembly state, the clamp rod 24 retracts, and the lifting platform 25 lifts the workpiece to the assembly position, completing the workpiece conveying process. Through the combined use of the arrangement feeding belt, the swing frame and the baffle, the workpiece can be efficiently transported to the clamping position of the clamp 2; through the cooperation of the lifting platform 25 and the clamp 2, the automatic clamping and conveying of the workpiece is realized, and the production efficiency is improved.

[0042] Specifically, when the clamp 2 is in the feeding state, the clamp 2 is lifted to the height of the swing frame by the lifting platform 25, the clamp 2 extends into the swing frame, the clamp rod 24 extends and uses the elastic limit belt to cover and fix the workpiece, and then the clamp 2 moves along the limit track 13, driving the swing frame to swing, and transporting the workpiece from the arrangement feeding belt to the assembly area. When the clamp 2 moves the workpiece to the bottom of the transverse track 31, the clamp 2 switches from the feeding state to the assembly state, the clamp rod 24 retracts, and the lifting platform 25 lifts the workpiece to the height of the transverse track 31; the transverse plate 32 on the transverse track 31 drives the clamp plate 33 to move through the telescopic cylinder to fix the workpiece in place, and the manipulator moves according to the preset program to accurately assemble the workpiece together; after the assembly is completed, the clamp plate 33 continues to keep the workpiece in a fixed position until all necessary assembly steps are completed. Through the coordinated use of the manipulator and the transverse track 31, the workpieces can be automatically positioned and assembled; the telescopic cylinder and the clamping plate 33 on the transverse track 31 ensure the precise alignment between the workpieces and improve the accuracy of assembly; strong flexibility: by adjusting the position of the transverse track 31 and the clamping plate 33, it can adapt to workpieces of different sizes and shapes.

[0043] The base 21 is mounted on the lifting platform 25 in a shaking manner; the base 21 is allowed to shake freely within a certain range to adapt to slight deviations of the workpieces during the assembly process and ensure that the center positioning between the workpieces is more accurate. The bottom end of the clamping plate 33 has a first guide surface for guiding the workpieces into the correct position. The top end of the movable block 22 has a second guide surface, which cooperates with the first guide surface to ensure that the workpieces can be accurately aligned during the assembly process.
