Description

Technical Field

[0001] The utility model relates to a press-fitting device, and more particularly to an upper carrier fixing device based on the product cover press-fitting device. Background Art

[0002] Most electronic products and smart products consist of a back cover and a cover, i.e., the screen. These two parts are usually bonded together, and during assembly, a press-fit device is often used to press the cover onto the back cover to achieve the desired assembly effect.

[0003] Most existing press-fitting equipment uses an upper carrier to fix the product cover on the pressing component of the equipment. In order to facilitate replacement, the upper carrier is mostly fixed to the pressing component through an electromagnet. However, if the power is suddenly cut off during operation, it is easy to cause the upper carrier to fall, thereby causing damage to the product or the carrier, affecting product quality and service life.

[0004] Therefore, it is necessary to propose a pressure-maintaining fixture to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0025] An upper carrier fixing device based on a product cover press-fitting device, such as Figure 1-Figure 5 As shown, it includes a body 1 and an upper carrier 2 and a lower carrier that cooperate with each other. A workbench 11 for placing the lower carrier is provided on the body 1. A lifting frame 4 is movably connected to the top of the workbench 11 along the vertical direction. The lifting frame 4 is provided with a limiting structure for limiting the upper carrier 2 from separating from the lifting frame 4. The body 1 is provided with a driving structure for driving the lifting frame 4 to reciprocate in the vertical direction.

[0026] The driving structure includes a linear driving module 3 fixedly connected to the body 1 and vertically arranged. The linear driving module 3 can use a linear motor, or a rodless cylinder or a screw module. The output end of the linear driving module 3 is fixedly connected to a driving block, and the driving block is fixedly connected to the lifting frame 4. Linear guide rails 12 are symmetrically arranged on both sides of the linear driving module 3, and a slider 43 that slides with the linear guide rail 12 is fixedly connected to one side of the lifting frame 4. By setting the linear guide rail 12 and the slider 43, the moving trajectory of the lifting frame 4 is limited, so that the lifting of the lifting frame 4 is more stable, and the linear driving module 3 is used to drive the lifting frame 4 to move up and down.

[0027] The limiting structure includes a clamping block and a clamping claw cylinder 42 that are symmetrically arranged with each other. The two output ends of the clamping claw cylinder 42 are fixedly connected to the clamping block through a connecting piece 421. The top of the upper carrier 2 is fixedly connected with two positioning blocks 21 that are symmetrically arranged with each other. The two clamping blocks are located between the two positioning blocks 21. The positioning block 21 and the side facing the clamping block are provided with an inclined surface. The end of the clamping block close to the positioning block 21 is provided with an inclined groove 4221 that cooperates with the inclined surface to form a guide surface. The clamping claw cylinder 42 is driven to drive the two clamping blocks away from each other, thereby approaching the positioning block 21 until the inclined surface of the positioning block 21 is formed. The inclined surface fits in with the inner bottom wall of the inclined groove 4221. The setting of the inclined surface has a good guiding effect, making positioning more convenient, and can divide the horizontal force into a vertical force, thereby better limiting the upper carrier 2 from separating from the lifting frame 4 in the vertical direction, ensuring the fixing effect; and the inclined groove 4221 is only provided at one end of the clamping block, so that the side wall of the inclined groove 4221 is a horizontal surface. When the inclined surface of the positioning block 21 fits in with the inner bottom wall of the inclined groove 4221, its side wall fits in with the side wall of the positioning block 21, thereby limiting the horizontal displacement and further ensuring the fixing effect;

[0028] The lifting frame 4 is provided with a fitting portion 41 at one end away from the body 1, and two clamping blocks are located on both sides of the fitting portion 41. The top of the upper carrier 2 is fitted with the bottom of the fitting portion 41, and an electromagnet 412 is provided at the bottom of the fitting portion 41 for adsorbing the upper carrier 2. The electromagnet 412 is used to adsorb the upper carrier 2, so that the upper carrier 2 can be fixed; a plurality of positioning shafts 411 are fixedly connected to the bottom of the fitting portion 41, and a positioning hole 23 for the positioning shaft 411 to pass through is provided at the top of the upper carrier 2. By setting the positioning shaft 411 and the positioning hole 23, the positioning effect of the upper carrier 2 is guaranteed, the positioning is more accurate, and the pressing effect of the overall equipment is guaranteed; the bottom of the fitting portion 41 is provided with a plurality of positioning shafts 411 There is a first vacuum suction cup 413, which is connected to the vacuum pump through a PL connector and an air pipe. Several second vacuum suction cups 22 are provided at the bottom of the upper carrier 2. A ventilation channel is provided on the upper carrier 2. One end of the ventilation channel is provided with a branch and is respectively connected to the second vacuum suction cups 22. The other end of the ventilation channel extends vertically to the top of the upper carrier 2 and is open. The first vacuum suction cup 413 is connected to the ventilation channel. When the bonding portion 41 is bonded to the upper carrier 2, the vacuum pump is run, and the second vacuum suction cup 22 on the upper carrier 2 can generate adsorption force through the first vacuum suction cup 413. There is no need to additionally connect the upper carrier 2 to the vacuum air pump, which is more convenient to use.

[0029] Working principle: bring the upper carrier 2 close to the lifting frame 4, so that the fitting part 41 fits with the top of the upper carrier 2, and the positioning shaft 411 is inserted into the positioning hole 23 to complete the positioning, the first vacuum suction cup 413 is connected to the ventilation channel, and the electromagnet 412 channel is used to complete the adsorption of the upper carrier 2; drive the clamping claw cylinder 42 to drive the two clamping blocks to move away from each other and approach the positioning block 21 until the inclined groove 4221 of the clamping block fits with the inclined surface of the positioning block 21, thereby achieving further limiting of the upper carrier 2. If a power outage occurs, the upper carrier 2 can be restricted by the clamping blocks, and the upper carrier 2 will not fall, thereby ensuring the service life of the instrument and the service life of the upper carrier 2; when the assembly of the product is completed, or the upper carrier 2 needs to be replaced, it is only necessary to drive the clamping claw cylinder 42 to make the two clamping blocks move closer to each other and away from the positioning block 21. The electromagnet 412 is powered off, and the upper carrier 2 can be easily separated from the lifting frame 4, achieving a quick change effect.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
