Along with the development of industries such as electronics, 5G communication and the like, the SMT chip mounter is also rapidly developed, the size of components is smaller and smaller, the SMT chip mounting density is higher and higher, and a novel packaging form is continuously introduced, so that the requirement on a suction nozzle of the SMT chip mounter is higher and higher for adapting to the requirements of high-density and high-difficulty SMT chip mounting processing and assembling technology.

The existing SMT suction nozzle cleaning and checking equipment mainly comprises an ultrasonic cleaning mechanism, a camera module for detecting dirt and/or blockage of the suction nozzle after cleaning, and a clamping jaw mechanism for clamping and moving the suction nozzle. The clamping jaw mechanism clamps and transfers the suction nozzle to be cleaned from the tray jig into the cleaning mechanism, clamps and transfers the cleaned suction nozzle into the drying mechanism for drying, clamps and transfers the dried suction nozzle into the checking equipment after the drying is finished, and clamps and transfers the checked suction nozzle into the tray jig for sending out or transferring into the storage equipment. The clamping jaw mechanism is generally a common clamping jaw, when the suction nozzle is transferred to a designated position and is put down, the suction nozzle only falls down by means of self gravity, and in addition, when the clamping force of the clamping jaw is large or the clamping jaw is loosened due to overlong time, the suction nozzle is temporarily stopped and left on the clamping jaw, so that the placing speed of the suction nozzle is slower, the working efficiency of equipment is lower, and further improvement is needed. The present utility model has been made to solve the above-mentioned problems.

Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

Examples

Referring to fig. 1 to 6, a suction nozzle gripping mechanism according to an embodiment of the present utility model includes a moving module 4, a mounting substrate 1, a clamping mechanism 2, and an elastic device 3. The preferred example in fig. 1 to 6 is that one moving module 4 is mounted with two mounting substrates 1, two clamping mechanisms 2 and two elastic devices 3. More specifically, the moving module 4 is a moving module 4 in a vertical direction. Two mounting substrates 1 are mounted on the moving module 4 in a staggered manner, each mounting substrate 1 is provided with a mounting surface, and a clamping mechanism 2 and an elastic device 3 are arranged on the mounting surface of one mounting substrate 1 side by side. More specifically, the clamping mechanism 2 comprises two clamping jaws 22 and a driving member 21 for driving the clamping jaws 22 in a clamping or unclamping motion. Any one of the elastic means 3 includes a mounting block 31 and an elastic member 32, the mounting block 31 being fixed to a mounting surface of the corresponding mounting substrate 1. Preferably, the driving member 21 of the clamping mechanism 2 is fixed to the mounting block 31 of the elastic means 3. Each jaw 22 has an outwardly extending gripping portion 221, the two gripping portions 221 being arranged opposite to define a gripping space. The mounting block 31 is provided with a through hole therethrough. One end of the elastic member 32 is fixed in the through hole in the mounting block 31, and the other end extends at least partially out of the end of the through hole facing the mounting space and extends into the holding space or out of the end of the holding space away from the mounting block 31, and in the embodiment of the present utility model, it is preferable that the elastic member 32 extends out of the end of the holding space away from the mounting block 31. Thus, when the clamping jaw 22 clamps the suction nozzle, the suction nozzle pushes the elastic component 32 to displace upwards so as to generate compression deformation to generate elastic potential energy. The elastic component 32 preferably comprises a movable push rod 321 and an elastic component 322 which is sleeved on the movable push rod 321, one end of the elastic component is connected to the second limiting wall 311 in the through hole, the other end of the elastic component is connected to the first limiting wall 3211 on the movable push rod 321, when the clamping jaw 22 does not clamp an object, the first limiting wall 3211 is positioned outside the through hole, after the clamping jaw 22 clamps the object, the elastic component 32 is abutted to the clamped object and is pushed by the clamped object to move back to the clamped object until the first limiting wall 3211 is abutted to the outer wall of the through hole so as to generate elastic potential energy for forcing the clamped object to rapidly fall off from the clamping jaw 22 after the clamping jaw 22 is loosened. Preferably, the direction of the elastic potential energy of the elastic means 3 in the embodiment of the utility model is in the vertical direction, i.e. coincides with the direction of gravity. According to the suction nozzle clamping mechanism, when objects such as suction nozzles are required to be put down, the elastic device 3 is utilized to push the objects such as the suction nozzles to rapidly fall off from the clamping jaw 22 due to the elastic potential energy generated by the pushing action of the objects to be clamped when the elastic device 3 clamps, and when the direction of the elastic potential energy of the elastic device 3 is consistent with the gravity direction, the superposition effect can be achieved, and the placing speed is further improved. That is, the utility model can achieve the purpose of increasing the placing speed even when the direction of the elastic potential energy is inconsistent with the gravity direction.

As an alternative embodiment, the elastic member 32 may include only one spring, that is, not include the movable push rod 321, where the mounting hole on the mounting block 31 may be a blind hole, or even the mounting block 31 does not need to be provided with a mounting hole, and one end of the spring is directly fixed on the mounting block 31 or fixed on the bottom wall of the blind hole, and the other end is used as an abutting end that abuts against the clamped object.

As an alternative, the elastic means 3 may not be provided, but a rigid pushing means such as a conventional cylinder or hydraulic cylinder may be provided, and the pushing member may be a cylinder shaft of the cylinder or a hydraulic rod of the hydraulic cylinder or a push rod connected to the cylinder shaft of the cylinder or the hydraulic rod of the hydraulic cylinder. Under the condition, the pushing component does not need to extend into the clamping space or even extend out of the clamping space when in the initial position, and only needs to apply force for forcing the objects such as the suction nozzle to drop on the objects such as the suction nozzle by driving the pushing component to abut against the objects such as the suction nozzle after the objects such as the suction nozzle are clamped by the clamping jaws.

The clamping portion 221 has an L-shaped clamping structure. According to some preferred embodiments of the present utility model, as shown in fig. 4, any of the clamping portions 221 is further provided with a clamping extension 222 extending away from the mounting block 31, and the clamping extension 222 is preferably arc-shaped as shown in fig. 4, to match the shape of the nozzle to be clamped. The end of any clamping extension 222 remote from the clamping portion 221, i.e. the lower end as shown in fig. 4, has a lateral extension 223, and the two clamping extensions 222 are opposite to each other and the two lateral extensions 223 are opposite to each other so as to jointly define a clamping space. The clamping extension 222 in the embodiment of the present utility model may not only play a role in reinforcing the clamping, but also play a role in guiding the displacement of the movable rod. The transverse extension 223 can limit the object support when the clamping jaw 22 clamps the object, so as to improve the clamping firmness. For the drive 21, it is preferably an existing conventional cylinder, that is to say the clamping mechanism 2 is preferably an existing conventional pneumatic clamping jaw 22.

According to some preferred embodiments of the utility model, the projection of the pushing member or elastic member 32 into the clamping space is in the center of the clamping space. That is, the pushing member or elastic member 32 is located at the center of the holding space, so that the holding jaw mechanism can conveniently center the suction nozzle, and the moving strokes of the two holding jaws 22 are consistent.

According to some preferred embodiments of the present utility model, as shown in fig. 5 and 6, the pushing member or movable push rod 321 is adapted to be connected to an external air source, and the pushing member or movable push rod 321 has a vent hole 3212 therein, the vent hole 3212 penetrating an end of the pushing member or movable push rod 321 facing the installation space. When the gripping jaw 22 grips an object such as a suction nozzle, the suction nozzle portion extends into the air hole 3212. Through the arrangement of the vent holes 3212, the functionality of the gripping mechanism can be enhanced, for example, the vent holes 3212 are arranged to suck air during gripping to improve the suction firmness of the gripped object, and blow air during putting down the gripped object to enable the gripped object to fall off the clamping jaw 22 more quickly. Also, for example, the vent 3212 may be provided for connection to a vacuum generating device such as a vacuum pump and measurement of the suction flow through the vent 3212 by a flow sensing device such as a flow meter to determine whether the suction nozzle is clogged.

According to some preferred embodiments of the utility model, the number of gripping means 2 is at least two, each gripping means 2 being provided with a respective elastic means 3. At least two clamping mechanisms 2 share one mounting substrate 1 or are mounted on at least two mounting substrates 1 in a one-to-one correspondence. When the at least two clamping mechanisms 2 are installed on the at least two installation substrates 1 in a one-to-one correspondence manner, the installation surfaces of the at least two installation substrates 1 form an included angle. As shown in fig. 1 to 4, the number of the clamping mechanisms 2 is two, the two clamping mechanisms 2 are correspondingly installed on the two installation substrates 1 one by one, the installation surfaces of the two installation substrates 1 are 90 degrees, specifically the installation surface of one installation substrate 1 faces backwards, and the installation surface of the other installation substrate 1 faces leftwards, so that interference can be avoided when the two clamping mechanisms 2 are installed and/or operated. The purpose of providing a plurality of gripping mechanisms 2 is to be able to perform the moving work of a plurality of suction nozzles at a time, further improving the efficiency of the whole apparatus.

According to some preferred embodiments of the present utility model, as shown in fig. 1 to 4, the diameters of the ventilation holes 3212 in the pushing parts of the two pushing devices or the movable push rod 321 of the two elastic devices 3 are different. The design can be used for suction nozzles with different sizes, and the applicability of the equipment is improved.

According to some preferred embodiments of the present utility model, as shown in fig. 1 to 3, a moving module 4 for driving the clamping mechanism 2 and the pushing means or elastic means 3 to displace at least in a vertical direction is further included, and the mounting substrate 1 is mounted on the moving module 4. In the embodiment of the present utility model, the moving module 4 is preferably a Z-axis moving module 4, that is, the clamping mechanism 2 and the pushing device are driven to move in an upgrade manner along the vertical direction or the Z-axis direction. As shown in fig. 1 to 3, the moving module 4 includes a slide rail and a driving part such as an electric cylinder. Two mounting substrates 1, one of which is slidably fitted on the slide rail in front of the moving module 4, and the other of which is slidably fitted on the slide rail on the side of the moving module 4. As an alternative embodiment, the movement module 4 may also be an XYZ three-axis movement module 4.

According to some preferred embodiments of the present utility model, the camera module is further provided on the mounting substrate 1 for photographing the clamped object. As shown in fig. 1 to 3, an imaging module is mounted on one of the mounting substrates 1, for example, the mounting substrate 1 on the rear left side as shown in fig. 2 (the imaging module is not mounted on the mounting substrate 1 on the front left side), and the imaging module is higher than the holding mechanism 2 on the mounting substrate 1 so that the object to be held under the holding mechanism can be clearly photographed. Preferably, the shooting range of the camera module can at least cover the objects clamped by the two clamping mechanisms 2, and the specific structure and the working principle of the camera module are not described or limited. As an alternative embodiment, an image pickup module may be mounted on each mounting substrate 1, and preferably, the image pickup module is provided with a light source, and the light source preferably adopts infrared rays. The camera module preferably recognizes two-dimensional code information on the suction nozzle jig tray to acquire the information of the suction nozzle jig tray and the suction nozzle to be cleaned, and judges whether the suction nozzle to be cleaned is matched with the cleaning jig in the ultrasonic cleaning mechanism. The camera module can also be used for shooting the surface dirt condition of the clamped objects such as the suction nozzle, for example, the suction nozzle only needs to be cleaned by ultrasonic waves if the suction nozzle only has dirt on the suction nozzle body. When the suction nozzle is only stained with the reflecting plate, the suction nozzle is only required to be cleaned by wiping the reflecting plate. When the suction nozzle body and the reflecting plate are both dirty, the suction nozzle body is required to be cleaned by ultrasonic waves, and the reflecting plate is required to be cleaned by wiping. Because the reflecting plate is directly stuck on the suction nozzle body by adopting the adhesive, and ultrasonic cleaning can cause the peeling of the adhesive or damage to the reflecting plate, the reflecting plate and the suction nozzle body are required to be cleaned in different modes respectively.

The embodiment of the utility model also discloses SMT suction nozzle cleaning and checking equipment, which comprises the suction nozzle clamping mechanism. The suction nozzle clamping mechanism of the embodiment is adopted, so that the suction nozzle clamping mechanism of the embodiment has at least the beneficial effects and is not repeated. Other structures of the SMT nozzle cleaning inspection apparatus are not described or defined in detail, and are not innovative points of the present utility model, and are readily known and implemented by those skilled in the art.
