The first cylinder 142 controls the movement of the first pressing plate 143, so that the pressing force can be finely adjusted in the fine adjustment stage, and the micro change of the distance between the first pressing plate 143 and the workpiece 700 can be realized by controlling the expansion and contraction of the piston rod of the first cylinder 142, so as to achieve the required pressure and fastening effect.

In addition, based on the difference of the installation heights of the first cylinders 142 on the first carrier 141, the heights of the first cylinders 142 and the first pressing plates 143 on the carrying plate 11 are convenient to adjust, and the positions of the first pressing plates 143 contacting the workpiece 700 to be machined are convenient to adjust.

The detachable connection between the mounting structure 111 and the first carrier 141 can be implemented in various manners, such as a threaded connection manner, a shaft pin connection manner, or a magnetic connection manner, and in different embodiments, the specific structures of the mounting structure 111 and the first carrier 141 are different, for example, when the threaded connection manner is adopted, the mounting structure 111 is a threaded hole, the first carrier 141 is correspondingly provided with a threaded hole, and the mounting and fixing of the first carrier 141 can be realized by sequentially connecting different threaded holes with bolts; when the shaft pin connection mode is adopted, the mounting structure 111 is a hole, holes are correspondingly formed in the first carrier 141, and the shaft pins or the pins sequentially penetrate through different holes, so that the mounting and fixing of the first carrier 141 can be realized; when the magnetic connection mode is adopted, the mounting structure 111 is a magnet, the first carrier 141 is correspondingly provided with a magnet, and the two magnets are magnetically attracted and connected, so that the mounting and fixing of the first carrier 141 can be realized.

the second carrier 151 is arranged on the carrying plate 11;

the second cylinder 152 is arranged on the second carrier 151 or the carrier plate 11, and a piston rod of the second cylinder 152 extends in the height direction of the machine body 100;

the second pressing plate 153 is slidably disposed on the carrying plate 11, and the second pressing plate 153 and the second positioning plate 13 are opposite to each other in the left-right direction of the machine body 100 and are disposed at intervals;

Thus, the effect of "the structure of the second pressing member 15 contacting the work piece 700 can be reciprocally moved in the left-right direction of the machine body 100" can be achieved.

The embodiment of "extending the piston rod of the second cylinder 152 in the left-right direction of the machine body 100 and driving the second pressing plate 153 to move so as to press the workpiece 700" is not adopted for the second pressing member 15, and it is considered that if the piston rod of the second cylinder 152 is extended in the left-right direction of the machine body 100, the width of the entire apparatus (length in the left-right direction) is increased by the presence of the second cylinder 152, and by reciprocally moving the piston rod of the second cylinder 152 in the height direction of the machine body 100 and moving the transmission plate 154 and the second pressing plate 153, only the height space of the machine body 100 is fully utilized, and the width of the machine body 100 is not increased.

The piston rod of the first cylinder 142 extends in the front-rear direction of the machine body 100, because several stations on the machine body 100 are sequentially disposed in the front-rear direction of the machine body 100, the piston rod of the first cylinder 142 extends in the front-rear direction of the machine body 100, which has little influence on the overall length of the apparatus (the length in the front-rear direction).

Referring to fig. 6, a piston rod of the second cylinder 152 is provided with a rotatable roller 155, and a peripheral surface of the roller 155 abuts against an end surface of the driving plate 154. The peripheral surface of the roller 155 can roll on the end surface of the transmission plate 154, the roller 155 is arranged to drive between the piston rod of the second air cylinder 152 and the transmission plate 154, it is easy to understand that the contact area between the roller 155 and the transmission plate 154 is larger, force transmission can be stably carried out, so as to drive the transmission plate 154 to move, meanwhile, the roller 155 can rotate relative to the transmission plate 154 in the process of moving up and down, and thus, larger friction force in the transmission process between the piston rod and the transmission plate 154 is avoided (if the roller 155 is not arranged, the piston rod directly contacts with the end surface of the transmission plate 154, the friction force between the piston rod and the end surface of the transmission plate 154 is sliding friction force, and the friction force in the transmission process is smaller than the sliding friction force through the design of the roller 155), which is beneficial to reducing unnecessary energy consumption and ensuring the smoothness in the transmission process.

A guide rail structure may be disposed between the second pressing plate 153 and the second carrier 151 to ensure accuracy of the moving direction of the second pressing plate 153, specifically, a guide groove (not labeled in the drawing) is disposed at the top of the second carrier 151, the guide groove extends in the left-right direction of the machine body 100, a sliding block 156 is disposed at a side portion of the second pressing plate 153 facing away from the second positioning plate 13, and the sliding block 156 is slidably disposed in the guide groove.

The number of the sliding blocks 156 can be two, the two sliding blocks 156 are in one-to-one correspondence with the two guide grooves, the two guide grooves are arranged in parallel, and the accuracy of the moving direction of the second pressing plate 153 is more firmly ensured by matching the plurality of sliding blocks 156 with the corresponding guide grooves.

Further, referring to fig. 5 and 6, a protruding block 159 is protruding from the top of the sliding block 156, a limiting plate 158 is further disposed between the protruding block 159 and the second pressing plate 153, and a spring 157 is disposed between the protruding block 159 and the limiting plate 158, as will be understood in conjunction with the figures, when the roller 155 moves upward, the second pressing plate 153, the sliding block 156, the protruding block 159, etc. are driven to move in a direction close to the second positioning plate 13, the spring 157 is pressed during the movement of the protruding block 159, when the roller 155 moves downward, the spring 157 is required to restore the original shape, the protruding block 159 is driven to move in a direction far from the second positioning plate 13, and then the sliding block 156, the second pressing plate 153, etc. are driven to move in a direction far from the second positioning plate 13, so that the components can be reset, and the workpiece 700 can be placed between the second positioning plate 13 and the second pressing plate 153 next time.

In the process of manufacturing the workpiece 700, even if the workpiece 700 is manufactured by the same processing apparatus according to the same specification, there may be different sizes of the workpiece 700, for example, in the workpiece 700 manufactured in the same batch, there may be a case where one of the workpiece 700 has a width of 30.0mm and a length of 50.0mm, and another of the workpiece 700 has a width of 30.08mm and a length of 50.01mm, and in order to cope with the above-mentioned case, the ink-jet area of the ink-jet device 200 is generally increased appropriately, for example, in the above-mentioned example, the width of the spraying area of the ink-jet device 200 may be set to a value of 30.08mm and even greater than 30.08mm, and the length of the spraying area of the ink-jet device 200 may be set to a value of 50.01mm and even greater than 50.01mm, so as to adapt to the size of the workpiece 700, so that the surface of each workpiece 700 may be covered with the paint.

In the above process, when the inkjet device 200 processes the workpiece 700 having a width of 30.0mm and a length of 50.0mm, since the inkjet device 200 can spray a larger area than the surface area of the workpiece 700, a part of the paint is sprayed around the workpiece 700, and over time, the unused paint is deposited and solidified at the processing position to form a deposit, requiring frequent cleaning by manpower, which is time-consuming and laborious.

Based on the above, it can be known that the existing printing apparatus does not have a product tolerance detection function, and the printing area cannot be adjusted according to the actual product size, so that the material is wasted, the fixture needs to be cleaned frequently, and time and effort are wasted, and for this purpose, in the design of the present application, the top of the carrier plate 11 is further provided with a length detector 3 and a width detector 4, and the length detector 3 is used for detecting the length of the workpiece 700 to be processed between the first positioning plate 12 and the first pressing member 14, and transmitting the detection data to the inkjet device 200;

the width detector 4 is used for detecting the width of the workpiece 700 to be processed between the second positioning plate 13 and the second pressing member 15, and transmitting detection data to the ink jet device 200;

the inkjet device 200 can adjust the inkjet area itself on the work piece 700 to be processed based on the detection data of the length detector 3 and the width detector 4.

Specifically, the ink jet device 200 has many ink jet holes in the nozzle for jetting ink, the gap between adjacent ink jet holes is small, which may be about 0.05mm, and the ink jet device 200 can adjust the area covered by the ink jet by controlling the opening and closing of the ink jet holes.

Before the ink jet device 200 performs ink jet, the ink jet holes of the corresponding areas are closed or opened according to the data detected by the length detector 3 and the width detector 4, so that the area covered by the ink jet device 200 can be adjusted, and thus, the ink jet device 200 can be conveniently adapted to different sizes of workpieces 700, for example, when the workpiece 700 with the width of 30.0mm and the length of 50.0mm is subjected to ink jet, the ink jet area of the ink jet device 200 can be adjusted to 30.0mm and the length of 50.0mm, and when the workpiece with the width of 30.08mm and the length of 50.01mm is subjected to ink jet, the ink jet area of the ink jet device 200 can be adjusted to 30.08mm and the length of 50.01mm, so that the paint can be fully utilized without being ejected to the positions around the workpieces 700.

In particular, in some embodiments, the length detector 3 (the width detector 4 is the same as the above) may be a laser sensor, an ultrasonic sensor, an infrared sensor, a radar sensor, or the like, and in this embodiment, the length detector 3 is mounted by arranging the detection end of the length detector 3 opposite to the first positioning plate 12 or the first pressing member 14 at a distance in the front-rear direction of the machine body 100, and the width detector 4 is mounted by arranging the width detector 4 opposite to the second positioning plate 13 or the second pressing member 15 at a distance in the left-right direction of the machine body 100

In other embodiments, the length detector 3 (the width detector 4 is similar) may be a CCD vision camera fixed directly above the product, and the length and width data of the workpiece 700 to be processed is transmitted to the inkjet device 200 by photographing detection.

The protective cover 18 is made of a light-absorbing material. The light absorbing material may be a black material, an organic dye, a semiconductor material, or the like.

The protective cover 18 is a covering mounted on the frame 17, and serves to protect components (e.g., the carrier plate 11, the first positioning plate 12, the second positioning plate 13, the first pressing member 14, the second pressing member 15, etc.) on the frame 17 from UV lamps, paint, or damage caused by the UV lamps, paint, so that corrosion, abrasion, or malfunction of the components on the frame 17 can be reduced, and the life of the apparatus can be prolonged.

At the same time, the protective cover 18 also blocks the transmission of noise, vibration or radiation, reducing interference and harm to the environment surrounding the device and to the operator.

In addition, the protective cover 18 can also avoid light reflection, and it has been said that, in the operation process of the ink jet device 200, the UV lamp is used for pre-curing, and in this process, light can be emitted onto the protective cover 18, and light reflection can be avoided through the absorption of the protective cover 18 to light, so that the ink jet device 200 is used for spraying the nozzle of the paint, so that the paint is not affected by the reflected light, and the paint is not cured at the nozzle, thereby ensuring the normal operation of the ink jet device 200.

The size of the exposing port 181 is adapted to the size of the workpiece 700 so that the gap between the peripheral wall of the workpiece 700 and the peripheral wall of the exposing port 181 is as small as possible, which is advantageous in preventing light and paint from moving to the parts on the frame 17.

The light barrier 501 can play a role in blocking light transmission, so as to ensure that light cannot penetrate from the final curing station 103 to the inkjet printing station 102, and is beneficial to avoiding influence on the operation of the inkjet device 200 caused by light generated in the working process in the final curing station 103.

The inkjet printing apparatus includes a sealing cap 500 and a fan assembly 600, the sealing cap 500 being capped at the curing device 300, a sidewall of the sealing cap 500 being formed as a light barrier 501, the fan assembly 600 being provided at an outer side of the sealing cap 500; the fan assembly 600 includes a first air inlet, which is communicated with the cavity in the sealed enclosure 500; the fan assembly 600 includes a second air inlet in communication with the inkjet printing station 102.

When the UV light irradiates the surface of the coating, the gases volatilize, and the volatilized gases are relatively bad, so that the workshop is easy to have peculiar smell, and the volatilized gases can be pumped away through the cooperation of the sealing cover 500 and the fan assembly 600, so that the peculiar smell is prevented from spreading.
