DETAILED DESCRIPTION

[0032] In order to more clearly illustrate the embodiments of the present application, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0033] In the description of the embodiments of the present application, terms such as "upper", "lower", "front", and "back" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the application.

[0034] According to some embodiments of the present application, Figures 1 to 7 As shown, a bonding machine protection device is provided, which is installed on the bonding machine, and the protection device includes two brackets 1, a sliding component 3, a balancing component and a locking component 4. The two brackets 1 are installed in parallel on the frame of the bonding machine; each bracket 1 is correspondingly provided with a sliding component 3, and a lifting door 2 is installed between the two sliding components 3, and the lifting door 2 moves up and down along the bracket 1; the balancing component is connected to the bracket 1 and the lifting door 2, and is used to balance the gravity when the lifting door 2 moves; the locking component 4 includes a magnet 41 and a magnetic suction sheet 42, the tops of the two brackets 1 are respectively provided with magnets 41, and the corresponding positions on both sides of the top of the lifting door 2 are respectively provided with magnetic suction sheets 42, and the magnetic suction sheets 42 cooperate with the magnet 41 to realize the opening and closing of the lifting door 2.

[0035] Specifically, the sliding assembly 3 includes a sliding rail 31 and a sliding block 32 . The sliding rail 31 is fixed to the bracket 1 . The sliding block 32 is slidably connected to the sliding rail 31 . The lifting door 2 is fixedly connected to the sliding block 32 .

[0036] Furthermore, a slide rail 31 is installed on each bracket 1, and a slider 32 cooperates with the slide rail 31 to provide guidance for the lifting door 2. A handle 21 is provided on the lifting door 2, and the lifting door 2 moves up and down along the bracket 1 by pulling the handle 21.

[0037] Since the lifting door 2 generates gravitational potential energy in the vertical direction due to its own weight, in order to overcome gravity when manually lifting the lifting door 2, a balancing component is provided in the embodiment of the present application, which can prevent the lifting door from falling rapidly due to its own gravity and balance the lifting door's own gravity when it rises.

[0038] Specifically, the balancing assembly includes a tension spring 13, the top end of which is connected to the bracket 1, and the bottom end of the tension spring 13 is connected to the lifting door 2. Since the tension spring 13 has the ability to rebound in the stretching direction, it can balance part of the gravitational potential energy of the lifting door 2 to achieve a labor-saving effect.

[0039] When the operator pulls the lifting door 2, the tension spring 13 will deform as the lifting door 2 moves, providing a pulling force for the lifting door 2. The pulling force and part of the gravity of the lifting door offset each other. Since the travel of the lifting door is short, the tension of the tension spring changes less. During the lifting process, the friction between the lifting door and the sliding assembly, the tension of the tension spring and the gravity of the lifting door itself are balanced, so that the lifting door can reach a hovering state during the lifting process. The operator can easily control the rise and fall of the lifting door, thereby achieving a labor-saving effect.

[0040] According to an embodiment of the present application, a flip cover assembly 5 is provided on the bracket 1, and the flip cover assembly 5 includes a fixed block 51, a rotating shaft 52 and a cover plate 53. The top ends of the two brackets 1 are respectively provided with a fixed block 51, and the rotating shaft 52 is installed between the two fixed blocks 51. The cover plate 53 is sleeved and rotatably matched with the rotating shaft 52 to realize the opening and closing of the cover plate 53.

[0041] Specifically, a fixing block 51 is respectively installed on the two brackets 1, and the two fixing blocks 51 serve as fixed ends. A rotating hole is provided in the middle of the fixing block 51, and the left and right ends of the rotating shaft 52 are respectively installed in the rotating holes. The rotating shaft 52 can rotate in the rotating holes. The cover 53 can be opened and closed by turning the flip cover 53 around the rotating shaft 52.

[0042] Since the height of the manual lifting door 2 is limited, and the door frame for loading and unloading the bonding machine does not need a large application scenario, through the added flip cover assembly 5, during normal loading and unloading, the cover plate 53 covers the loading and unloading door frame, and the manual lifting door does not need to be lifted very high. When the bonding machine needs to be repaired, more space is required, and the cover plate can be opened for manual maintenance.

[0043] According to an embodiment of the present application, the locking assembly 4 also includes a safety door lock 43, which includes a door lock buckle 431 and a latch 432. The door lock buckle 431 is arranged on a side bracket, and the latch 432 is arranged on the lifting door 2. The latch 432 is plugged into and matched with the door lock buckle 431.

[0044] Furthermore, the safety door lock 4 is provided with an induction coil, which electrically cooperates with the latch 432 to generate an electrical signal, and transmits the electrical signal to the control system, so that the safety door lock 43 can lock and limit the lifting door 2, ensuring that the lifting door 2 will not fall. When the lifting door 2 is pulled into place, it is necessary to keep the lifting door from falling, and at the same time transmit the lifting door in place signal to the bonding machine. This requirement can be met by the induction coil in the safety door lock 43 and the latch. Since the locking force of the safety door lock 43 is a fixed value, it is necessary to cooperate with a magnet to provide a more suitable locking force during use.

[0045] Furthermore, the lifting door 2 and / or the cover plate 53 are respectively configured as a transparent acrylic plate or a PC plate. The lifting door is configured as a transparent plate by using acrylic material or PC material, which has good light transmission performance and beautiful and smooth effect.

[0046] Further, a pressing plate 12 is provided on both sides of the lifting door 2, and the pressing plate 12 is fixedly connected to the lifting door 3. The lifting door 3 is mounted on the slider through the pressing plate 12, so that the pressing plate, the lifting door and the slider move synchronously.

[0047] According to the embodiment of the present application, a hydraulic buffer 11 is provided at the bottom end of the bracket 1, and the hydraulic buffer 11 contacts and cooperates with the pressure plate 12. The contact between the pressure plate 12 and the hydraulic buffer 11 can reduce the impact vibration during the descent of the lifting door 2, thereby playing a buffering role.

[0048] The protective device according to the embodiment of the present application can not only protect the products in the bonding machine, but also protect the safety of the operator. The structural design of the protective device is simple and practical. When the lifting door is lifted, the lifting process is smooth and there is no sense of frustration. The lifting door feels light.

[0049] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, X and / or Y may represent: X exists alone, X and Y exist at the same time, and Y exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like 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, and 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 embodiments of the present application can be understood according to the specific circumstances.

[0051] The above description is only a detailed description of the preferred embodiments and principles of the present application. For ordinary technicians in this field, there will be changes in the specific implementation methods based on the ideas provided by the present application, and these changes should also be regarded as the scope of protection of the present application.
