Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a reciprocating feeding screen printing device. Background Technology

[0002] Currently, screen printing of outer shell products typically uses a turntable to transport the shells. While this method is efficient, the rotation requirement places high demands on the pneumatic components and air circuits of the fixtures, which is not conducive to cost reduction. Utility Model Content

[0003] This invention addresses the problems of existing technologies by providing a reciprocating feeding screen printing device that ensures a certain level of efficiency in transporting outer shell products while having lower requirements for the air circuit.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a reciprocating feeding screen printing device, including a machine body, a feeding mechanism and a printing mechanism both disposed on the machine body. The feeding mechanism includes a feeding drive module, a feeding table and two feeding clamps. The two feeding clamps are respectively disposed at the top two ends of the feeding table. The feeding drive module is used to drive the feeding table to move horizontally back and forth. When one feeding clamp moves to directly below the printing mechanism, the other feeding clamp is located outside the printing mechanism to load and unload materials.

[0005] Furthermore, the feeding fixture includes a base and multiple positioning mechanisms. The base is provided with a protrusion for insertion into the housing, and the multiple positioning mechanisms are located around the protrusion. The protrusion is provided with a number of positioning holes, and each positioning hole is movably provided with a positioning block. The base is also provided with a drive module for driving the positioning blocks to extend and retract.

[0006] Furthermore, the protrusion is provided with a driving hole, which is connected to the positioning hole; the driving module includes a linear driver, a push block and several reset components, the reset components are disposed between the positioning block and the protrusion, and the linear driver is used to drive the push block to rise and fall; the side wall of the push block is provided with a first inclined surface, and the end of the positioning block is provided with a second inclined surface that abuts against the first inclined surface.

[0007] Furthermore, the reset component is a spring, the protrusion is also provided with a guide hole, the positioning block is provided with a guide part, the reset component is located in the guide hole, and the two ends of the reset component are respectively connected to the inner sidewall of the guide hole and the guide part.

[0008] Furthermore, the base is also provided with a support cover and a lifting drive module. The support cover is elliptical and can be mounted on the base, with the protrusion located outside the support cover. The lifting drive module is used to drive the support cover to rise and fall.

[0009] Furthermore, the support cover is provided with alignment holes, which are used to communicate with the positioning holes after the support cover is lifted by the drive module.

Detailed Implementation

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, the present invention provides a reciprocating feeding screen printing device, including a body 1, a feeding mechanism 2 and a printing mechanism 3 both disposed on the body 1. The feeding mechanism 2 includes a feeding drive module 4, a feeding table 5 and two feeding clamps 6. The two feeding clamps 6 are respectively disposed at the top ends of the feeding table 5. The feeding drive module 4 is used to drive the feeding table 5 to move horizontally back and forth. When one feeding clamp 6 moves to directly below the printing mechanism 3, the other feeding clamp 6 is located outside the printing mechanism 3 to load and unload materials.

[0022] In practical applications, the printing mechanism 3 is a conventional screen printing mechanism, which will not be described further here. During operation, the housing is first placed into a feeding fixture 6, which then clamps the housing. The feeding drive module 4 then drives the feeding table 5 to slide, moving the feeding fixture 6 directly below the printing mechanism 3. While the printing mechanism 3 is performing screen printing, another feeding fixture 6 is located outside the printing mechanism 3. At this time, the housing can be loaded / changed using this other feeding fixture 6... This reciprocating action achieves the effect of continuous operation. Since the feeding table 5 moves along a straight line, the requirements for the air circuit structure are lower than those for rotary motion, which helps to simplify the air circuit structure and reduce costs.

[0023] In this embodiment, the feeding fixture 6 includes a base 61 and a plurality of positioning mechanisms 62. The base 61 is provided with a protrusion 63 for insertion into the housing. The plurality of positioning mechanisms 62 are located around the protrusion 63. The protrusion 63 is provided with a plurality of positioning holes 631, and each positioning hole 631 is movably provided with a positioning block 64. The base 61 is also provided with a drive module 65 for driving the positioning blocks 64 to extend and retract.

[0024] When the outer shell is clamped by the feeding fixture 6, the side of the outer shell to be printed is placed on the protrusion 63 with the side facing up. The protrusion 63 is inserted into the outer shell through the opening. Then, the drive module 65 drives the positioning block 64 to extend and abut against the inner wall of the outer shell. At the same time, the positioning mechanism 62 moves to abut against the outer wall of the outer shell. The positions abutted by the positioning block 64 and the positioning mechanism 62 are basically the same, so that the outer shell is subjected to force on both sides of the clamped position, effectively avoiding deformation of the outer shell.

[0025] In this embodiment, the number of positioning mechanisms 62 and the number of positioning blocks 64 are set according to the length and width of the outer shell. For example, in this embodiment, there are six positioning mechanisms 62 and six positioning blocks 64, and the six positioning mechanisms 62 and the six positioning blocks 64 are set facing each other one by one.

[0026] In this embodiment, a driving hole 632 is provided in the protrusion 63, and the driving hole 632 communicates with the positioning hole 631; the driving module 65 includes a linear driver 651, a push block 652 and a plurality of reset members 653, the reset members 653 are disposed between the positioning block 64 and the protrusion 63, and the linear driver 651 is used to drive the push block 652 to rise and fall; the side wall of the push block 652 is provided with a first inclined surface 654, and the end of the positioning block 64 is provided with a second inclined surface 641 that abuts against the first inclined surface 654.

[0027] The linear actuator 651 is preferably a cylinder, which is less expensive than a motor screw mechanism. During operation, the linear actuator 651 drives the push block 652 to rise. The push block 652 uses the first inclined surface 654 to force the positioning block 64 to extend outward toward the protrusion 63, while simultaneously squeezing the reset member 653. When it is necessary to release the housing, the linear actuator 651 resets, and when the reset member 653 returns to its shape without being subjected to the external force of the linear actuator 651, it forces the positioning block 64 to retract back into the positioning hole 631.

[0028] Specifically, the reset element 653 is a spring, the protrusion 63 is also provided with a guide hole 633, the positioning block 64 is provided with a guide portion 642, the reset element 653 is located in the guide hole 633, and the two ends of the reset element 653 are respectively connected to the inner sidewall of the guide hole 633 and the guide portion 642. The setting of the guide hole 633 allows the reset element 653 to deform and recover along the sliding direction of the positioning block 64, thereby ensuring that the elastic force of the reset element 653 acts on the positioning block 64 with the highest efficiency.

[0029] Furthermore, the positioning mechanism 62 includes a positioning cylinder 621 and a positioning clamping block 622. The positioning clamping block 622 is installed on the piston rod of the positioning cylinder 621 and is used to abut against the outer wall of the housing.

[0030] The positioning cylinder 621 drives the positioning clamping block 622 to move back and forth to clamp and release the outer shell, thereby achieving the desired external clamping effect.

[0031] like Figure 5 As shown, as another embodiment of the feeding clamp 6 of this utility model, the following features can be added to the structure of the feeding clamp 6 described above: The base 61 is also provided with a support cover 66 and a lifting drive module 67. The support cover 66 is elliptical and detachable on the base 61, and the protrusion 63 is located outside the support cover 66. The lifting drive module 67 is used to drive the support cover 66 to rise and fall.

[0032] The lifting drive module 67 is preferably a cylinder, specifically used to control the lifting and lowering of the support cover 66. Compared to the above embodiments, this embodiment is mainly used for clamping larger housings. These housings have certain tolerances (e.g., 1-2 cm), which can affect the printing effect. In this embodiment, after the housing is placed on the protrusion 63, the support cover 66 is used to hold the inner top wall of the housing against and lift it a certain distance. Even if the housing has different depths due to tolerances, the support cover 66 is sufficient to compensate for this tolerance after it is raised to a certain height. At this time, clamping it ensures that the external printing mechanism 3 will contact the housing and print when it descends to a preset height.

[0033] Specifically, the support cover 66 is provided with an alignment hole 661, and a positioning hole 631 is used to communicate with the positioning hole 631 after the support cover 66 is lifted by the drive module 67. Only after the support cover 66 is raised to the required height can the positioning hole 631 be exposed to the outside through the alignment hole 661, thereby ensuring the clamping effect that can only be achieved after the support cover 66 is raised.

[0034] In this embodiment, the feeding drive module 4 includes a feeding linear driver 41, a first sensor 42, and two second sensors 43. The feeding linear driver 41 is used to drive the feeding table 5 to move back and forth. The first sensor 42 is installed on the machine body 1, and the two second sensors 43 are both installed on the feeding table 5. The first sensor 42 is signal-connected to the feeding linear driver 41.

[0035] In actual use, the feeding linear driver 41 is preferably a motor lead screw module, the first sensor 42 is a photoelectric switch, and the second sensor 43 is a shield for triggering the first sensor 42.

[0036] That is, by means of the second sensor 43 moving with the feeding table 5, when the second sensor 43 triggers the first sensor 42, that is, the corresponding side of the feeding table 5 is in position, at this time the feeding linear drive 41 stops moving, so that the feeding table 5 no longer moves and stays in this state, so that the printing mechanism 3 can accurately screen print on the outer shell on the feeding fixture 6 directly below.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
