DETAILED DESCRIPTION

[0033] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] This embodiment provides a dispensing device, which is mainly used for the dispensing process of screens of electronic products (mobile phones, tablet computers, etc.). In the dispensing device, a brake mechanism is used to stop the rotating parts to prevent the dispensing device from tipping over and causing collision damage.

[0039] The existing brake mechanism uses electric energy to stop the rotating parts. The motor has a complex structure, requires a large installation space, and has a high cost. At the same time, when the dispensing device is in operation, the existing brake mechanism cannot stop the rotating parts in time when the power is cut off and the air is cut off, resulting in brake failure.

[0040] To solve the above problems, this embodiment also proposes a brake mechanism, which is used in the process of stopping the rotating parts of the dispensing device. Of course, the brake mechanism can also be used in other devices or equipment. Figure 1 to Figure 3 As shown, the brake mechanism includes a bracket 1, a brake member 4, an elastic member 5 and a driving member 6. A brake disc 2 is rotatably arranged on the bracket 1, and the brake disc 2 is configured to be coaxially connected with the rotating member. The brake member 4 is slidably arranged on the bracket 1 along the height direction of the bracket 1 (the up and down direction in the figure). The elastic member 5 is compressed and installed between the brake member 4 and the bracket 1 to elastically support the brake member 4. Under the action of the elastic member 5, the brake member 4 always has a tendency to rise along the height direction of the bracket 1, and can contact and hold the brake disc 2. The driving member 6 is arranged on the bracket 1 and connected to the brake member 4 to drive the brake member 4 to descend along the height direction of the bracket 1 and make the brake member 4 disengage from the brake disc 2. Under the action of the elastic member 5, the brake member 4 rises along the height direction of the bracket 1 until the brake member 4 contacts and holds the brake disc 2 to achieve the braking function. Under the action of the driving member 6, the brake member 4 overcomes the elastic restoring force of the elastic member 5 and descends along the height direction of the bracket 1 until the brake member 4 disengages from the brake disc 2 to release the brake. Since the brake mechanism realizes the braking function through the elastic member 5, the structure is simple, and the installation space and cost of the brake mechanism are reduced. At the same time, the brake mechanism realizes the braking function through the mechanical energy of the elastic member 5, without the use of electrical components such as motors, and can realize the brake failure function under extreme working conditions such as power failure and air failure, thereby ensuring the reliability and stability of the brake mechanism.

[0041] Specifically, a brake disc 2 is rotatably mounted on the front side of the bracket 1, and a connecting member 10 is correspondingly mounted on the rear side of the bracket 1. The rotating shaft of the brake disc 2 passes through the bracket 1 and is coaxially connected to the connecting member 10, and the connecting member 10 is fixedly connected to the rotating component so that the brake disc 2 is coaxially connected to the rotating component. When the brake disc 2 is held tightly by the brake member 4, the rotating component can be driven to stop. The above-mentioned driving member 6 is a cylinder, and the cylinder has a simple structure and is easy to install and maintain, so as to achieve compact installation of the driving member 6 without occupying too much installation space. In other embodiments, the driving member 6 can also be other components such as a motor, and it only needs to be able to drive the brake member 4 to move up and down along the height direction of the bracket 1.

[0042] like Figure 2 and Figure 3As shown, the brake member 4 includes a brake frame 41 and a clamping block 42. The bracket 1 is slidably provided with the brake frame 41 in the height direction, and the output end of the driving member 6 is connected to the brake frame 41. The elastic member 5 is compressed and installed between the brake frame 41 and the bracket 1. The clamping block 42 is provided at the top of the brake frame 41, and the clamping block 42 can contact and clamp the brake disc 2. By providing the brake member 4 as a split structure of the brake frame 41 and the clamping block 42, it is convenient to disassemble and replace the clamping block 42 that is severely worn, without replacing the entire brake member 4, thereby reducing the maintenance cost.

[0043] Furthermore, the brake frame 41 is provided with a communicating clearance hole 415 and a clearance groove 416, and the clearance groove 416 is located below the clearance hole 415. The driving member 6 is located in the clearance hole 415, and the output end of the driving member 6 is clamped in the clearance groove 416. The clearance hole 415 is used to avoid the driving member 6 installed on the front side of the bracket 1, so that the driving member 6 and the brake frame 41 are compactly installed. In addition, the driving member 6 does not increase the size of the brake mechanism in the height direction, and further reduces the installation space of the brake mechanism in the height direction.

[0044] Specifically, the main body of the driving member 6 is located in the clearance hole 415, and the output end of the driving member 6 is clamped in the clearance groove 416. When the driving member 6 is closed, the output end of the driving member 6 can freely rise and fall along the height direction with the brake frame 41, so as to avoid the driving member 6 interfering with the lifting and moving process of the brake frame 41. Under the action of the elastic member 5, the brake frame 41 rises in the height direction of the bracket 1, and the clamping block 42 contacts and clamps the brake disc 2, so that the brake disc 2 and the rotating component stop synchronously. When the driving member 6 is turned on, the output end of the driving member 6 drives the brake member 4 to descend in the height direction of the bracket 1, so that the clamping block 42 is out of contact with the brake disc 2 to release the brake.

[0045] like Figure 2 and Figure 3As shown, the bracket 1 is provided with a detection member 7, which is used to detect whether the brake member 4 is lowered to the disengaged position along the height direction of the bracket 1, and the brake member 4 at the disengaged position is out of contact with the brake disc 2. The detection member 7 of this embodiment is a photoelectric sensor, and a light shielding plate 8 is provided on the brake frame 41. When the driving member 6 drives the brake frame 41 to descend along the height direction of the bracket 1, the light shielding plate 8 can trigger the photoelectric sensor when it synchronously descends with the brake frame 41 to the height where the photoelectric sensor is located, and at this time, the clamping block 42 is out of contact with the brake disc 2. The photoelectric sensor generates a corresponding trigger signal, and transmits the trigger signal to the control module of the brake mechanism or the dispensing device through a wiring harness or wireless communication. After receiving the trigger signal, the control module controls the driving member 6 to stop, so as to avoid the collision between the brake frame 41 and the bottom of the bracket 1 (i.e., the carrier 11), thereby improving the safety of the lifting and moving process of the brake member 4. It should be noted that the control module is a common control component of the brake mechanism or the dispensing device, and the structure and working principle of the control module are not described in detail. The above-mentioned disengagement of the clamping block 42 from the brake disc 2 means that: along the height direction of the bracket 1, the height of the bottom end of the brake disc 2 is greater than the height of the top end of the clamping block 42, so that the clamping block 42 and the brake disc 2 are completely separated.

[0046] Furthermore, one of the bracket 1 and the brake member 4 is provided with a slider 9, and the other of the bracket 1 and the brake member 4 is provided with a slide rail, and the slider 9 is in sliding cooperation with the slide rail. Through the sliding cooperation between the slider 9 and the slide rail, it is possible to avoid positional displacement of the brake member 4 when it is lifted and moved along the height direction of the bracket 1, thereby improving the stability of the lifting and moving process of the brake member 4. Specifically, both ends of the front side of the bracket 1 along the length direction (the left and right directions in the figure) are provided with slide rails extending along the height direction of the bracket 1, and the brake frame 41 is correspondingly installed with sliders 9 on the left and right sides along the length direction. By providing two sets of slidingly matched sliders 9 and slide rails, the stability of the lifting and moving process of the brake member 4 is further improved. In other embodiments, both ends of the left and right sides of the front side of the bracket 1 are provided with sliders 9, and the left and right sides of the brake frame 41 are correspondingly provided with slide rails extending along the height direction of the bracket 1.

[0047] like Figure 2 and Figure 3 As shown, the brake member 4 is provided with a receiving hole 411 along the height direction of the bracket 1. A carrier 11 is provided at the bottom end of the bracket 1. The carrier 11 is located below the brake member 4 along the height direction of the bracket 1. One end of the elastic member 5 extends into the receiving hole 411, and the other end of the elastic member 5 extends out of the receiving hole 411 and is pressed against the carrier 11. The elastic member 5 extends into the receiving hole 411 to achieve the limited installation of the elastic member 5, avoid the elastic member 5 from twisting and deforming during the compression process, and improve the reliability and stability of the elastic member 5.

[0048] Specifically, the elastic member 5 of this embodiment is a spring with a simple structure, which is easy to install and replace. A groove is provided on the upper surface of the carrier 11, and the bottom end of the elastic member 5 extending out of the receiving hole 411 is installed in the groove, so that the receiving hole 411 and the groove can jointly realize the limited installation of the elastic member 5, further improving the reliability and stability of the elastic member 5. There are two elastic members 5 in this embodiment, and a receiving hole 411 is provided on both sides of the brake frame 41. A carrier 11 is correspondingly provided on both sides of the bottom end of the bracket 1, so that the two elastic members 5 jointly provide an upward elastic restoring force to the brake frame 41, so as to improve the clamping force between the clamping block 42 and the brake disc 2, avoid the risk of brake failure due to too small clamping force, and improve the braking efficiency of the brake disc 2.

[0049] like Figure 2 and Figure 3 As shown, the brake member 4 is also provided with a through hole 412 in the height direction of the bracket 1 and connected to the receiving hole 411. The through hole 412 is internally threaded with an adjusting rod 3, and one end of the adjusting rod 3 extends into the receiving hole 411 and presses against the elastic member 5. Due to the threaded connection between the adjusting rod 3 and the through hole 412, the position of the adjusting rod 3 along the axial direction (up and down direction in the figure) of the through hole 412 can be adjusted by simply screwing the adjusting rod 3, so as to adjust the compression amount of the elastic member 5, thereby adjusting the clamping force between the clamping block 42 and the brake disc 2. The above-mentioned adjusting rod 3 is a bolt.

[0050] Furthermore, the brake member 4 is provided with a visible hole 413 along the height direction of the bracket 1, and the visible hole 413 is connected to the receiving hole 411. The outer edge of the visible hole 413 is provided with a scale line 414 extending along the height direction of the bracket 1. The end of the adjusting rod 3 extending into the receiving hole 411 selectively points to different scale values ​​of the scale line 414. By providing the visible hole 413, it is convenient for the operator to intuitively check the compression of the elastic member 5. At the same time, when the adjusting rod 3 is screwed, the bottom end of the adjusting rod 3 moves up and down in the receiving hole 411. Through the visible hole 413, the scale value aligned with the end face of the bottom end of the adjusting rod 3 before adjustment and the scale value aligned with the end face of the bottom end of the adjusting rod 3 after adjustment can be viewed, and the compression amount of the elastic member 5 can be obtained according to the difference between the two scale values ​​before and after adjustment.

[0051] like Figure 4As shown, a friction groove 421 is provided at the top of the clamping block 42, and the friction groove 421 is adapted to the outer contour of the brake disc 2. The inner wall of the friction groove 421 includes an arc-shaped bottom wall and a side wall of a planar structure, and the bottom wall of the friction groove 421 is concentrically arranged with the brake disc 2, so that the bottom wall of the friction groove 421 is completely fitted with the circumferential side of the brake disc 2, and at the same time, the side wall of the friction groove 421 is completely fitted with the axial end face of the brake disc 2, so that the inner wall of the friction groove 421 is completely fitted with the outer contour of the brake disc 2, thereby increasing the contact area between the friction groove 421 and the brake disc 2, so as to increase the clamping force between the clamping block 42 and the brake disc 2, thereby realizing the braking function.

[0052] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
