In the related art, a pressure holding device is generally used to hold pressure for the display screen, the pressure-sensitive double-faced adhesive and the middle frame. Some pressure holding devices include a cylinder and two clamping ends that can be moved relatively closer to or farther away from each other by actuation of the cylinder. When pressure maintaining is carried out, the two clamping ends can be relatively close to each other, wherein one clamping end abuts against one side, far away from the middle frame, of the display screen, and the other clamping end abuts against one side, far away from the display screen, of the middle frame; the air cylinder drives the two clamping ends to clamp the display screen, the pressure-sensitive double-sided adhesive and the middle frame from two sides, and the pressure-sensitive double-sided adhesive is applied with required pressure to achieve the purpose of pressure maintaining. The two clamping ends may each have a roller-type structure for reliable and safe clamping in contact with the display/bezel.

As shown in fig. 1, the present embodiment provides a holding pressure detection device, which includes a device base 1, a fixing clamp 2, a movable clamp 3 and a dynamometer 4, and can rapidly detect a holding pressure of a holding pressure device 200, so that the holding pressure is controlled within an allowable range, thereby improving product yield.

The fixed jig 2 is fixedly provided on the apparatus base 1, and the movable jig 3 is slidably provided on the apparatus base 1. As shown in fig. 1 to 2, here, the movable jig 3 is connected to one of the holding ends 201 of the holding pressure device 200, for example, a first holding end 201', and the fixed jig 2 is connected to the other holding end 201 of the holding pressure device 200, for example, a second holding end 201 ″, so that the holding pressure device 200 is mounted on the holding pressure detecting means. Since the stationary jig 2 is kept stationary and the movable jig 3 is slidable, the movable jig 3 is slidable relative to the stationary jig 2, thereby matching the process of the approaching clamping action of the two clamping ends 201 of the holding pressure device 200. Accordingly, when the two clamping ends 201 are driven to approach relatively by the air cylinder after the pressure maintaining device 200 is started, the second clamping end 201 "is limited by the fixed clamp 2 and remains stationary, and the second clamping end 201" drives the movable clamp 3 to move synchronously, so that the movable clamp 3 and the fixed clamp 2 approach relatively.

The load cell 4 is fixedly arranged on the device base 1, and the load cell 4 has a load cell rod end 41. The force measuring rod end 41 and the movable clamp 3 can be connected directly or indirectly, and the acting force of the movable clamp 3 can be measured. The type of the dynamometer 4 may be determined according to actual needs, and may be a type such as a dial/digital display tension meter, a dial/digital display thrust meter, a dial/digital display push-pull force meter, etc., which is not limited in the embodiments of the present application. Accordingly, the load cell rod end 41 may be of the type of pull rod end 41' of a tension meter, push rod end 41' of a thrust meter, push/pull rod end 41' of a push-pull force meter, or the like.

When the pressure maintaining pressure detection device is used for detecting the pressure maintaining force of the pressure maintaining equipment 200, the two clamping ends 201 of the pressure maintaining equipment 200 can be connected to the fixed clamp 2 and the movable clamp 3 respectively, and then the pressure maintaining equipment 200 such as an air cylinder therein is started, so that the two clamping ends 201 are relatively close to target positions which are enough to clamp the display screen, the pressure-sensitive double-faced adhesive and the middle frame; in the process, the clamping end 201 connected to the fixed clamp 2 is limited by the fixed clamp 2 and is kept static, the clamping end 201 connected to the movable clamp 3 drives the movable clamp 3 to move synchronously, the movable clamp 3 moves to pull the force measuring rod end 41 of the force measuring meter 4, so that the force measuring meter 4 can measure the stress of the movable clamp 3, the purpose of detecting the holding pressure of the pressure holding equipment 200 is achieved, the holding pressure is controlled within an allowable range, and the product yield is improved.

The arrangement positions of the fixed jig 2, the movable jig 3 and the dynamometer 4 may be determined according to actual needs, and the embodiment of the present application is not limited thereto. As shown in fig. 1 to 3, in some embodiments, the force measuring rod end 41 may be a pull rod end 41 'capable of measuring a pulling force, and the fixed clamp 2, the movable clamp 3 and the force gauge 4 may be sequentially disposed at intervals, such that the holding pressure applied by the fixed clamp 2 and the movable clamp 3 is transmitted to the pull rod end 41' in a pulling force manner so as to be measured by the force gauge 4. In other embodiments, as shown in fig. 4, the force measuring rod end 41 may be a push rod end 41 ″ capable of measuring a pushing force, and the fixed clamp 2 and the force gauge 4 may be disposed on the same side of the movable clamp 3, so that the holding pressure applied by the fixed clamp 2 and the movable clamp 3 is transmitted to the push rod end 41' in a pushing manner so as to be measured by the force gauge 4.

As shown in fig. 1 to 4, in some embodiments, the holding pressure detecting means may further include an adjusting mechanism 5. Here, the adjusting mechanism 5 may include an adjusting sleeve 51 and an adjusting lever 52. One end of the adjusting sleeve 51 is in threaded connection with the force measuring rod end 41, while the other end is in threaded connection with the adjusting rod 52; the adjustment lever 52 is provided to the movable jig 3 so as to be rotatable in the circumferential direction, that is, the adjustment lever 52 is rotatable in the circumferential direction thereof, and a degree of freedom of rotation in the circumferential direction of the adjustment lever 52 is provided between the adjustment lever 52 and the movable jig 3. For example, the two ends of the adjusting sleeve 51 may be respectively provided with internal threads, and the force measuring rod end 41 and the adjusting rod 52 may be respectively provided with external threads, so that the two ends of the adjusting sleeve 51 are respectively in threaded connection with the force measuring rod end 41 and the adjusting rod 52.

When the adjusting sleeve 51 is rotated, the force measuring rod end 41 is restricted by the force gauge 4 and cannot rotate, and the adjusting sleeve 51 and the force measuring rod end 41 rotate relatively, so that the adjusting sleeve 51 rotates spirally on the force measuring rod end 41, and the adjusting sleeve 51 and the force measuring rod end 41 change relative positions along the axial direction of the adjusting sleeve 51; since the adjustment lever 52 is provided on the movable clamp 3 so as to be rotatable in the circumferential direction, the adjustment lever 52 can perform a helical rotation movement in synchronization with the adjustment sleeve 51, so that the adjustment lever 52 and the load cell bar end 41 also undergo a relative positional change in the axial direction of the adjustment sleeve 51, and the adjustment lever 52 drives the movable clamp 3 to move in synchronization in the axial direction of the adjustment sleeve 51. On the contrary, when detecting the holding pressure of the holding pressure device 200, the movable clamp 3 can drive the adjusting rod 52 to approach the fixed clamp 2 synchronously, so that the holding pressure applied by the movable clamp 3 and the fixed clamp 2 can be transmitted to the force measuring rod end 41 through the adjusting rod 52 and the adjusting sleeve 51 to be measured by the force gauge 4.

Thus, the position between the movable clamp 3 and the fixed clamp 2 can be changed by rotating the adjusting sleeve 51, so that the movable clamp 3 and the fixed clamp 2 can be matched with the pressure maintaining devices 200 of different specifications, the pressure maintaining devices 200 of different specifications can be installed to the pressure maintaining pressure detection device, the detection requirements of the pressure maintaining of various pressure maintaining devices 200 are met, and the adaptability and the application range of the pressure maintaining pressure detection device are increased. In addition, the force measuring rod end 41 and the adjusting rod 52 are connected by the adjusting sleeve 51 through threads, so that the force measuring machine 4 and the movable clamp 3 can be connected with each other at high precision, the movable clamp 3 and the force measuring rod end 41 of the force measuring machine 4 can have good synchronous movement precision, and the measuring precision of the force measuring machine 4 on the pressure maintaining force can be improved.

In some examples, the adjustment mechanism 5 may further include a limit structure 53 disposed on the adjustment lever 52. The movable clamp 3 is provided with a connecting hole 31, and one end of the adjusting rod 52 close to the force measuring rod end 41 passes through the connecting hole 31 and then is in threaded connection with the adjusting sleeve 51. The type of the connecting hole 31 may be determined according to actual needs, and may be a type such as a through hole, a slot hole, and the like, which is not limited in this embodiment.

As shown in fig. 1 to 3, for example, the force measuring rod end 41 may be a tie rod end 41', and the limiting structure 53 may abut against an end surface of the connecting hole 31 far from the force measuring rod end 41, so that the adjusting sleeve 51 and the limiting structure 53 are respectively disposed on two opposite sides of the connecting hole 31; when the pressure maintaining force of the pressure maintaining device 200 is detected, the movable clamp 3 approaches the fixed clamp 2 under the action of the driving force of the pressure maintaining device 200, the movable clamp 3 drives the adjusting rod 52 to approach the fixed clamp 2 synchronously through the limiting structure 53 and to be relatively far away from the dynamometer 4, so that the pull rod end 41 'is under the action of the pulling force, and further, the pressure maintaining force applied by the movable clamp 3 and the fixed clamp 2 is transmitted to the pull rod end 41' in the form of the pulling force and can be measured by the dynamometer 4.

As shown in fig. 4, for another example, when the force measuring rod end 41 may be a push rod end 41 ″, the limiting structure 53 may abut against an end surface of the connection hole 31 near the force measuring rod end 41, so that the adjusting sleeve 51 and the limiting structure 53 are located on the same side of the connection hole 31, that is, the connection hole 31 faces the force measuring rod end 41; when the pressure maintaining force of the pressure maintaining equipment 200 is detected, the movable clamp 3 approaches the fixed clamp 2 under the action of the driving force of the pressure maintaining equipment 200, the movable clamp 3 drives the adjusting rod 52 to approach synchronously through the limiting structure 53 and approach relatively to the dynamometer 4, so that the push rod end 41 ″ is subjected to the thrust action, and further, the pressure maintaining force applied by the movable clamp 3 and the fixed clamp 2 is transmitted to the push rod end 41 ″ in the form of thrust and can be measured by the dynamometer 4.

The configuration of the limiting structure 53 can be determined according to actual needs, and the embodiment of the present application does not limit this. For example, the limit structure 53 may be a limit flange portion formed on the adjustment lever 52, such as a flange structure formed to protrude on the outer circumferential side of the adjustment lever 52. As another example, the limiting structure 53 may be a limiting ring sleeved on the outer periphery of the adjusting rod 52. As another example, the limiting structure 53 may be a limiting nut 531, and the limiting nut 531 is in threaded connection with the adjusting rod 52, so that tightness adjustment can be performed; when the specification of the pressure maintaining equipment 200 to be detected exceeds the installation range of the movable clamp 3 and the fixed clamp 2, the limit nut 531 can be rotated to adjust the length of the adjusting rod 52 protruding out of the movable clamp 3, the stroke range between the movable clamp 3 and the fixed clamp 2 is further increased, and the detection requirement of the pressure maintaining equipment 200 to be exceeded is met. For another example, the number of the limiting nuts 531 may be two, and the two limiting nuts 531 may be sequentially abutted and pressed against each other, so as to achieve a better anti-loosening effect.

As shown in fig. 5, in other embodiments, the holding pressure detecting means may further include another adjusting mechanism 5. Here, the adjusting mechanism 5 may include a first adjusting member 51 'and a second adjusting member 52'. The first adjuster 51 'has one end connected to the load cell end 41 and the other end provided with a rack portion 511', and the second adjuster 52 'has one end connected to the movable clamp 3 and the other end provided with a toothed portion 521'. The first and second adjusting pieces 51 'and 52' are slidably coupled in the sliding direction of the movable clamp 3, and the rack portion 511 'and the convex tooth portion 521' are engaged with each other to be restricted. Thus, when the relative position between the movable clamp 3 and the fixed clamp 2 needs to be adjusted, a driving force can be applied to overcome the engagement limiting force between the rack portion 511' and the convex tooth portion 521' to drive the first adjusting piece 51' and the second adjusting piece 52' to slide relatively, so that the movable clamp 3 can change the relative position between the movable clamp 3 and the fixed clamp 2 along with the synchronous sliding of the second adjusting piece 52'. In the process of detecting the holding pressure, the engagement limit force between the rack portion 511 'and the toothed portion 521' prevents the first adjuster 51 'and the second adjuster 52' from sliding relative to each other, and the first adjuster 51 'and the second adjuster 52' can synchronously slide along with the movable clamp 3, so that the holding pressure applied by the movable clamp 3 and the stationary clamp 2 can be transmitted to the force measuring rod end 41 through the first adjuster 51 'and the second adjuster 52' to be measured by the force measuring gauge 4.

The configuration of the rack portion 511' may be determined according to actual needs, and the embodiment of the present application does not limit this. In some examples, the rack portion 511' may include a plurality of engagement teeth 5111', the plurality of engagement teeth 5111' are sequentially distributed in the sliding direction of the movable clamp 3, and the convex tooth portion 521' may be engaged between any adjacent two engagement teeth 5111 '. In this way, the first and second adjusting members 51 'and 52' can be held in a plurality of different relative positions, so that the movable clamp 3 and the fixed clamp 2 can be adjusted to different relative positions.

As shown in fig. 1 to 4, the shape and structure of the fixing jig 2 may be determined according to actual needs to match the shape and structure of the clamping end 201 of the pressure holding apparatus 200, which is not limited in the embodiment of the present application.

Based on the clearance fit relationship, the first clamping end 201' can be easily inserted into the first insertion hole 21, thereby reducing the installation difficulty. In some examples, the gap between the first plug aperture 21 and the first clamping end 201' may be 4-6 mm, such as 4mm, 4.5mm, 5mm, 5.5mm, or 6mm, etc.; within this clearance range, the clamping ends 201 of the pressure holding devices 200 of different specifications can be easily inserted into the first insertion holes 21 without adjusting the relative positions between the movable clamp 3 and the fixed clamp 2, increasing the convenience of operation.

The shape and structure of the movable clamp 3 can be determined according to actual needs to match the shape and structure of the clamping end 201 of the pressure holding device 200, which is not limited in the embodiment of the present application. In some embodiments, the movable clamp 3 may be provided with a second insertion hole 32, the second insertion hole 32 is configured to be inserted into the second clamping end 201 "of the pressure maintaining device 200, and the second insertion hole 32 and the second clamping end 201" have a clearance fit relationship therebetween. Based on the clearance fit relationship, the second clamping end 201 ″ can be easily inserted into the second insertion hole 32, and the installation difficulty is reduced. In some examples, the gap between the second plug hole 32 and the second clamping end 201 "may be 4-6 mm, such as 4mm, 4.5mm, 5mm, 5.5mm, or 6mm, etc.; within this clearance range, the clamping ends 201 of the pressure holding devices 200 of different specifications can be easily inserted into the second insertion holes 32 without adjusting the relative positions between the movable clamp 3 and the fixed clamp 2, increasing the convenience of operation.

In some embodiments, the dwell pressure detection apparatus may further include a fixing member 7, the fixing member 7 being configured to compressively fix the load cell 4 to the apparatus base 1.
