Description

Technical Field

[0001] The invention relates to equipment for closing and assembling two products, and in particular to a device for closing two products by relative rotation. Background Art

[0002] In industrial production, many products need to be combined into a combined product before they can be used. Some products have two parts connected together and must be closed by rotation. For such products, two clamps that are relatively and rotatably set are generally used to close the two parts. The two clamps are rotated to the middle to close the two parts. For example, in the production of battery cells, it is necessary to close the two battery cells connected by the tabs together to form a whole, and then add the outer shell to form a battery pack for use. However, in addition to the two parts that close to the middle on both sides, many products also include connecting parts in the middle connection part. If only two relatively and rotatably set clamps are used to achieve the closing of such products, the space occupied by the middle connection part will gradually decrease during the closing process, which is easy to cause the middle connection part to be crushed; for example, there is an end cover plate connected between the battery cells connected by the two tabs. If the core is closed in the above manner, it is easy to cause the end cover plate or the battery cell to be crushed by rotation. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a closing device that can solve the deficiencies in the background technology.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a closing device, comprising a first closing mechanism, a second closing mechanism and an auxiliary moving mechanism arranged between the first closing mechanism and the second closing mechanism, wherein the first closing mechanism and the second closing mechanism can rotate relative to each other and close, and the auxiliary moving mechanism can be linearly moved in the closing direction of the first closing mechanism and the second closing mechanism. Thus, the first closing mechanism and the second closing mechanism are relatively closed to achieve the closing of the product, and during the closing process, the auxiliary moving mechanism is away from the closing surface to make room for the product and avoid the product from being crushed during the closing process.

[0005] Furthermore, the first closing mechanism and the second closing mechanism can both be rotatable, providing a closing method in which both the first closing mechanism and the second closing mechanism can be rotatable, and the closing speed is faster.

[0006] Furthermore, the first closing mechanism and the second closing mechanism are both slidably arranged, thereby enabling the closing of products of different thicknesses, thereby increasing the practical scope of the closing device.

[0007] Furthermore, the first closing mechanism is arranged on the first mounting plate, and the second closing mechanism is arranged on the second mounting plate; and a support is further included, and the support is connected to the first mounting plate and the second mounting plate through a parallel slide rail mechanism and a screw mechanism, thereby providing rotational power for the first closing mechanism and the second closing mechanism.

[0008] Furthermore, the screw connected to the screw mechanism is provided with two sections of threads with opposite thread directions, and the first mounting plate and the second mounting plate are independently provided on the two sections of threads of the screw, thereby realizing a unified drive for the sliding of the first closing mechanism and the second closing mechanism, which can be realized with only one driving power, and can save material costs.

[0009] Furthermore, the first closing mechanism can be rotatably arranged on the first mounting plate, and the first closing mechanism is driven to rotate by the first rotation driving mechanism; the second closing mechanism can be rotatably arranged on the second mounting plate, and the second closing mechanism is driven to rotate by the second rotation mechanism. Thus, a more specific driving structure of the first closing mechanism and the second closing mechanism is provided.

[0010] Furthermore, the auxiliary moving mechanism is driven by a moving driving mechanism, the moving driving mechanism includes a linear driving mechanism and a sliding bracket, and the linear driving mechanism drives the sliding bracket to move perpendicular to the moving direction of the linear driving mechanism. Thus, a driving structure of an auxiliary moving mechanism is provided.

[0011] Furthermore, the linear drive mechanism includes a drive member and a drive block, the drive member drives the drive block to perform linear motion; the drive sliding bracket is slidably arranged in a direction perpendicular to the motion direction of the linear drive mechanism, the drive sliding bracket is provided with a slide groove which forms an acute angle with the motion direction of the linear drive mechanism, and the drive block is slidably arranged in the slide groove. Thus, a specific drive structure is provided, which can increase the carrying capacity of the auxiliary moving mechanism.

[0012] Furthermore, the driving member is a screw mechanism. Thus, a driving member is provided.

[0013] Furthermore, the first closing mechanism, the second closing mechanism and the auxiliary moving mechanism are all provided with clamps, thereby the product can be fixed on the first closing mechanism, the second closing mechanism and the auxiliary moving mechanism.

[0014] The beneficial effects achieved by the present invention are mainly as follows: an auxiliary moving mechanism is provided, and as the first closing mechanism and the second closing mechanism are gradually closed, the auxiliary moving mechanism gradually moves away from the first closing mechanism and the second closing mechanism, leaving a movable space for the structure connecting the two parts of the product to avoid compression damage to the product; the first closing mechanism and the second closing mechanism can be slidably arranged, so that the rotation axes of the first closing mechanism and the second closing mechanism can be arranged near the middle of the first closing mechanism and the second closing mechanism, and the closing of the product can be achieved through the movement and coordination of the auxiliary moving mechanism, so that the torque when driving the first closing mechanism and the second closing mechanism to rotate is smaller and the driving is easier; and the closing device can also be used for closing operations of products of different thicknesses, thereby enhancing the versatility of the equipment and saving equipment costs.

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Embodiment 1

[0023] See also Figures 1 to 5A closing device includes an auxiliary moving mechanism 3, a first closing mechanism 1 and a second closing mechanism 2 are arranged opposite to each other and can rotate relative to each other to close together. One of the first closing mechanism 1 and the second closing mechanism 2 can be arranged in a rotatable manner, and the product can be closed by rotating one of them and closing with the other; the first closing mechanism 1 and the second closing mechanism 2 can also be arranged in a rotatable manner to close the two parts of the product. It is best to adopt a method in which both of them can rotate, which can improve the closing operation efficiency and increase the flexibility of the closing device. The first closing mechanism 1 and the second closing mechanism 2 are arranged on opposite sides of the auxiliary moving mechanism 3. The auxiliary moving mechanism 3 supports the structure connecting the two parts of the product in the middle and moves to make room for the structure connecting the two parts of the product that moves during the closing process. The auxiliary moving mechanism 3 can move linearly in the closing direction of the first closing mechanism 1 and the second closing mechanism 2. For example, if the first closing mechanism 1 and the second closing mechanism 2 are in a horizontal state when separated and in a vertical state when closed, the auxiliary moving mechanism 3 rises and falls in the vertical direction, that is, the auxiliary moving mechanism 3 can move linearly in the closing surface direction of the first closing mechanism 1 and the second closing mechanism 2. By setting the auxiliary moving mechanism 3, as the first closing mechanism 1 and the second closing mechanism 2 gradually close, the auxiliary moving mechanism 3 gradually moves away from the first closing mechanism 1 and the second closing mechanism 2, leaving space for movement for the structure connecting the two parts of the product, thereby avoiding pressure damage to the product.

[0024] See also Figure 2 , the first closing mechanism 1 and the second closing mechanism 2 can be slidably arranged, so that the first closing mechanism 1 and the second closing mechanism 2 can maintain a relatively long distance at the beginning of closing, and gradually slide closer to each other to close the product during closing. The first closing mechanism 1 and the second closing mechanism 2 can be slidably arranged, so that the rotation axis of the first closing mechanism 1 and the second closing mechanism 2 can be set at a position close to the middle of the first closing mechanism 1 and the second closing mechanism 2, and then the closing of the product can be achieved through the movement and coordination of the auxiliary moving mechanism 3, so that the torque when driving the first closing mechanism 1 and the second closing mechanism 2 to rotate is smaller and the driving is easier; and the closing device can also be used for closing operations of products of different thicknesses, which enhances the versatility of the equipment and saves equipment costs.

[0025] See also Figure 2, the sliding of the first closing mechanism 1 and the second closing mechanism 2 can adopt the following structure: the first closing mechanism 1 is arranged on the first mounting plate 11, and the second closing mechanism 2 is arranged on the second mounting plate 21. It also includes a support 5, and the support 5 is connected to the first mounting plate 11 and the second mounting plate 21 through a parallel slide rail mechanism and a screw mechanism. The screw connected to the rod mechanism is provided with a thread, and the thread on the screw is divided into two sections, and the two sections of the thread are in opposite directions. One section of the thread of the screw is connected to the first mounting plate 11, and the other section of the thread of the screw is connected to the second mounting plate 21. Thus, the screw is driven by a rotation drive mechanism such as a motor, so that the first mounting plate 11 and the second mounting plate 21 connected to the screw can be simultaneously approached to the middle or simultaneously away from the middle position, so as to facilitate the control of the consistency of the actions of the first closing mechanism 1 and the second closing mechanism 2, and the closing accuracy is higher.

[0026] See also Figure 2 The first closing mechanism 1 can be rotatably arranged on the first mounting plate 11, and the first closing mechanism 1 is driven to rotate by the first rotation drive mechanism 12. The second closing mechanism 2 can be rotatably arranged on the second mounting plate 21, and the second closing mechanism 2 is driven to rotate by the second rotation mechanism 22. The first closing mechanism 1 and the first mounting plate 11, and the second closing mechanism 2 and the second mounting plate 21 can be connected by a rotating shaft and a bearing, and the first rotation drive mechanism 12 and the second rotation mechanism 22 can both use a reduction motor.

[0027] See also Figure 3 and 4 , the auxiliary moving mechanism 3 is driven by the auxiliary moving mechanism driving mechanism 4, the moving driving mechanism 4 includes a linear driving mechanism 41 and a sliding bracket 42, the linear driving mechanism 41 drives the sliding bracket 42 to move perpendicular to the moving direction of the linear driving mechanism 41. The linear driving mechanism 41 includes a driving member 411 and a driving block 412, the driving member 411 drives the driving block 412 to move linearly; the driving member 411 can be a screw mechanism, a cylinder, etc., and a cylinder is used in this embodiment. The driving sliding bracket 42 is slidably arranged in a direction perpendicular to the moving direction of the linear driving mechanism 41, and a slide groove 421 is arranged on the driving sliding bracket 42, which is at an acute angle to the moving direction of the linear driving mechanism 41, and the driving block 412 is slidably arranged in the slide groove 421. In order to reduce the friction between the driving block 412 and the slide groove 421 and extend the life of the equipment, a roller is arranged on the driving block 412, and the roller is rollingly arranged in the slide groove 421.

[0028] For example, a base plate can be provided, the screw of the driving member 411 is provided parallel to the base plate and can rotate, the screw nut is provided on the base plate through a slide rail mechanism, the driving motor is connected to the screw, so that the screw nut can be driven to slide by the rotation of the screw, and the driving block 412 is fixed on the screw nut. The sliding bracket 42 is provided on the base plate through a vertical slide rail mechanism, so that the linear driving mechanism 41 can only make linear motion in a direction parallel to the base plate, and the sliding bracket 42 can only make linear motion in a direction perpendicular to the base plate. An inclined slide groove 421 is provided to connect the two motions together, and the linear driving mechanism 41 can drive the sliding bracket 42 to move up and down by telescoping. The driving member 411 drives the sliding bracket 42 to move in a direction perpendicular to the base plate through a motion parallel to the base plate. Since the closing device is generally placed horizontally, it gradually becomes vertical during the closing process, and the gravity of the two parts of the product is gradually transferred to the auxiliary moving mechanism 3. The auxiliary moving mechanism of the above structure has a stronger driving force, which can make the auxiliary moving mechanism 3 more capable of bearing force and better adapt to the function of the auxiliary moving mechanism 3.

[0029] See also Figure 1 The first closing mechanism 1, the second closing mechanism 2 and the auxiliary moving mechanism 3 are all provided with clamps. Blocks can be set around the surface formed by the first closing mechanism 1, the second closing mechanism 2 and the auxiliary moving mechanism 3, and the slider is driven by a cylinder to clamp the product. The block can also be set to clamp the product through a spring elastic setting.

[0030] See also Figure 1 and 5 The working process of the closing device of this embodiment is as follows: the closing device is placed horizontally, and the product is placed in the closing device through other equipment such as a manipulator, and the two side parts of the product are placed on the first closing mechanism 1 and the second closing mechanism 2 respectively, and the middle part of the product is placed on the auxiliary moving mechanism 3; then the first rotating drive mechanism 12 and the second rotating mechanism 22 drive the first closing mechanism 1 and the second closing mechanism 2 to rotate and start closing the product, at the same time, the auxiliary moving mechanism 3 gradually descends, and the first closing mechanism 1 and the second closing mechanism 2 also gradually move closer to the middle; finally, the first closing mechanism 1 and the second closing mechanism 2 rotate to a vertical state and completely bring the left and right parts of the product together, that is, close them, and after closing, the material can be unloaded through a manipulator or the like.
