DETAILED DESCRIPTION

[0062] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0063] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0064] The utility model discloses a material moving device for dust-free handling equipment, as shown in the attached Figures 1 to 4 As shown, it includes a material moving frame 2, a vertical screw feeding module 3 and a longitudinal screw feeding module 4. The material moving frame 2 is used to support the magazine 1. The vertical screw feeding module 3 is fixedly connected to the material moving frame 2 and is used to drive the material moving frame 2 to move back and forth vertically. The longitudinal screw feeding module 4 is fixedly connected to the vertical screw feeding module 3 and is used to drive the material moving frame 2 to move back and forth longitudinally through the vertical screw feeding module 3. It should be noted that the attached Figure 1 Based on the current view, the vertical direction in the text refers to the height direction parallel to the material moving device, and the longitudinal direction in the text refers to the length direction parallel to the material moving device.

[0065] When shifting materials, the longitudinal screw feeding module 4 first moves the material shifting frame 2 from the initial position from left to right along the longitudinal direction, and the vertical screw feeding module 3 then moves the material shifting frame 2 vertically from bottom to top to the target material receiving position, and the material shifting frame 2 receives the clip 1; the longitudinal screw feeding module 4 moves the material shifting frame 2 longitudinally from the target material receiving position from right to left, and the vertical screw feeding module 3 then moves the material shifting frame 2 vertically from top to bottom until it reaches the target feeding position, and the clip 1 is unloaded at the target feeding position.

[0066] The utility model optimizes the structure of the material moving device, and changes the original belt feeding module into a screw feeding module. The screw feeding module is usually composed of metal parts such as a screw and a slider. The wear resistance of these metal parts is better than that of a belt made of rubber, that is, the wear resistance of the screw feeding module is better than that of the belt feeding module. Dust generated by belt wear during the feeding process is eliminated, and the entire material moving device generates less dust when working, so it is more suitable for occasions with higher dust-free requirements.

[0067] The vertical screw feeding module 3 includes a vertical drive motor 30, and the longitudinal screw feeding module 4 includes a longitudinal drive motor 40. The structures of both the vertical drive motor 30 and the longitudinal drive motor 40 can be servo motors.

[0068] The material moving device further comprises a controller, a first longitudinal distance sensor and a material receiving position sensor, and the controller is connected to the longitudinal driving motor 40, the first longitudinal distance sensor and the material receiving position sensor respectively.

[0069] When the controller receives the material receiving instruction, the controller starts the longitudinal drive motor 40 to rotate until the material moving frame 2 automatically moves the first set distance from the initial position in the longitudinal direction. When the first longitudinal distance sensor detects that the material moving frame 2 moves the first set distance in the longitudinal direction, the first longitudinal distance sensor feedbacks a signal to the controller. After the controller makes a comparison and judgment, the controller controls the longitudinal drive motor 40 to automatically stop rotating, and simultaneously starts the vertical drive motor 30 to automatically rotate until the material moving frame 2 rises vertically to the target material receiving position. When the material receiving position sensor detects that the material moving frame 2 moves vertically to the target material receiving position, the material receiving position sensor feedbacks a signal to the controller, and the controller controls the vertical drive motor 30 to automatically stop rotating. The setting of the first longitudinal distance sensor and the material receiving position sensor can enable the longitudinal screw feeding module 4 and the vertical screw feeding module 3 to automatically move successively between the initial position and the target material receiving position, so that the material moving frame 2 automatically reaches the target material receiving position, with a high degree of automation and low manual participation, which is conducive to improving production efficiency.

[0070] The material receiving instruction in the text may be generated by the controller according to the trigger signal fed back by the button switch, or the controller may be generated according to the trigger signal fed back by the sensor. The first set distance refers to the longitudinal distance from the initial position to the target material receiving position.

[0071] The material moving device also includes a material receiving identification sensor, a second longitudinal distance sensor and a feeding position sensor respectively connected to the controller. When the material receiving identification sensor detects that the clip 1 is transferred from the target material receiving position to the material moving frame 2, the material receiving identification sensor feedbacks a signal to the controller, and the controller automatically starts the longitudinal drive motor 40 to rotate until the material moving frame 2 moves the second set distance from the target material receiving position along the longitudinal direction with the clip 1. When the second longitudinal distance sensor detects that the material moving frame 2 moves the second set distance along the longitudinal direction, the second longitudinal distance sensor feedbacks a signal to the controller, and the controller controls the longitudinal drive motor 40 to automatically stop rotating, and at the same time automatically starts the vertical drive motor 30 to rotate, until the material moving frame 2 descends vertically with the clip 1 until reaching the target feeding position. When the feeding position sensor detects that the material moving frame 2 transports the clip 1 to the target feeding position, the feeding position sensor feedbacks a signal to the controller, and the controller controls the vertical drive motor 30 to automatically stop rotating. The arrangement of the material receiving identification sensor, the second longitudinal distance sensor and the feeding position sensor enables the longitudinal screw feeding module 4 and the vertical screw feeding module 3 to automatically move successively between the target material receiving position and the target feeding position, which is beneficial to further improve production efficiency.

[0072] The second set distance in the text sets the longitudinal distance between the target material receiving position and the target material feeding position. The material receiving identification sensor can be an obstacle sensor, a pressure sensor or a camera.

[0073] The material moving device also includes a feeding identification sensor and a lowest position sensor respectively connected to the controller. When the feeding identification sensor detects that the magazine 1 is transferred from the material moving frame 2 to the target feeding position, the feeding identification sensor sends a signal to the controller, and the controller starts the vertical drive motor 30 to rotate until the material moving frame 2 drops to the lowest position. When the lowest position sensor detects that the material moving frame 2 drops to the lowest position, the lowest position sensor feeds back a signal to the controller, so that the controller starts the longitudinal drive motor 40 to rotate until the material moving frame 2 reaches the initial position. The setting of the feeding identification sensor and the lowest position sensor can enable the material moving frame 2 to automatically return to the initial position from the target feeding position to prepare for the next feeding, so that the entire moving process of the material moving frame 2 can be fully automated, with high position accuracy and high degree of automation, which can further improve production efficiency.

[0074] It should be noted that the controller should include a signal receiving unit, a signal judging unit and a signal sending unit. The signal receiving unit is used to receive the electrical signal sent by the detection components such as the first longitudinal distance sensor, the material receiving position sensor, the material receiving identification sensor, the second longitudinal distance sensor, the feeding position sensor, the feeding identification sensor or the lowest position sensor. The signal judging unit is electrically connected to the signal receiving unit so that the signal judging unit is used to judge whether the signal received by the signal receiving unit is a trigger signal. The signal sending unit is electrically connected to the signal judging unit so that the signal sending unit sends the judgment signal generated by the signal judging unit to the execution components such as the vertical drive motor 30 or the longitudinal drive motor 40. The specific setting methods of the signal receiving unit, the signal judging unit and the signal sending unit can refer to the prior art; in the present utility model, only the application scenarios of the above three are changed, and no substantial improvement is made to them. Obviously, the controller with this structure is widely used in existing automatic control equipment, such as MCU, DSP or single-chip microcomputer. The key point of the present utility model is that the controller combines each detection component and each execution component.

[0075] As attached Figure 7 As shown, the longitudinal screw feeding module 4 also includes a longitudinal drive screw 41, a longitudinal fixed seat 42, a longitudinal guide slide 44, a longitudinal drive slider 45 and a longitudinal guide slider 46. The longitudinal drive screw 41 is fixedly connected to the longitudinal drive motor 40 through a coupling. The longitudinal fixed seat 42 is fixedly arranged and mainly plays a supporting role. The longitudinal fixed seat 42 is surrounded by a top side plate, a bottom side plate, a front side plate and a rear side plate. Two longitudinal support beams 43 are fixedly arranged on the top of the longitudinal fixed seat 42, and a longitudinal mounting groove is formed between the two longitudinal support beams 43. The longitudinal mounting groove is used to accommodate the longitudinal drive screw 41. This sinking design can make the overall structure more compact. The longitudinal guide slide 44 is fixed to the longitudinal support beam 43. The longitudinal drive slider 45 can be slidably arranged in the longitudinal mounting groove, and the longitudinal drive slider 45 is installed on the longitudinal drive screw 41. When the longitudinal drive screw 41 rotates, the longitudinal drive slider 45 reciprocates in the longitudinal direction. The longitudinal guide slider 46 is fixedly connected to the longitudinal drive slider 45 and slidably cooperates with the longitudinal guide rail 44, so that the longitudinal guide slider 46 slides longitudinally along the longitudinal guide rail 44 along with the longitudinal drive slider 45. Of course, the structure of the longitudinal screw feeding module 4 is not limited thereto.

[0076] The longitudinal screw feeding module 4 further includes a side support plate 47, a wiring groove 48 and a drag chain 49. The side support plate 47 is fixedly arranged on the side of the longitudinal fixing seat 42 to support the drag chain 49. The wiring groove 48 is fixedly arranged on the top of the longitudinal fixing seat 42, and contains cables. One end of the drag chain 49 is fixedly connected to the side support plate 47, and the other end is slidably connected to the wiring groove 48. The drag chain 49 wraps the cables together to prevent the cables from being worn during the movement of the longitudinal screw feeding module 4.

[0077] As attached Figure 8 As shown, the vertical screw feeding module 3 also includes a vertical driving screw 31, a vertical sliding seat 32, a vertical guide slide rail 34, a vertical driving slider 35 and a vertical guiding slider 36. The vertical driving screw 31 is fixedly connected to the vertical driving motor 30 through a coupling. The vertical sliding seat 32 is respectively fixedly connected to the material moving frame 2 and the longitudinal guiding slider 46, so that the longitudinal guiding slider 46 drives the vertical sliding seat 32 to move longitudinally, so that the material moving frame 2 moves synchronously with the vertical sliding seat 32 along the longitudinal direction. The vertical sliding seat 32 is fixedly provided with two vertical support beams 33, and a vertical mounting groove is formed between the two vertical support beams 33. The vertical mounting groove is used to accommodate the vertical driving screw 31, so that the structure of the vertical screw feeding module 3 is more compact. The vertical guide rail 34 is fixed to the vertical support beam 33, and the vertical driving slider 35 is slidably arranged in the vertical mounting groove. The vertical driving slider 35 is installed on the vertical driving lead screw 31 and is fixedly connected to the material moving frame 2. When the vertical driving lead screw 31 rotates, the vertical driving slider 35 brings the material moving frame 2 to move vertically synchronously. The vertical guide slider 36 is fixedly connected to the material moving frame 2, and the vertical guide slider 36 is slidably matched with the vertical guide rail 34, so that the vertical guide slider 36 cooperates with the vertical guide rail 34 to guide the material moving frame 2 to move vertically.

[0078] As attached Fig. 9 As shown, the material moving frame 2 includes a connecting beam 21, a left connecting plate 22, a right connecting plate 23, a supporting beam 24 and a supporting frame 25. There are at least two connecting beams 21, all of which are arranged in parallel and are fixedly connected to the vertical driving slider 35. The left connecting plate 22 is arranged on the left side of all the connecting beams 21, and the right connecting plate 23 is arranged on the right side of all the connecting beams 21, that is, all the connecting beams 21 are connected in parallel between the left connecting plate 22 and the right connecting plate 23. The supporting beam 24 is arranged between the left connecting plate 22 and the right connecting plate 23. The supporting frame 25 is fixedly arranged on the supporting beam 24 and is used to support the magazine 1.

[0079] The support frame 25 includes a left support plate 251 and a right support plate 252 which are arranged opposite to each other. An inverted U-shaped plate 253 is fixed on the top of the left support plate 251 and the right support plate 252. Figure 5 As shown, the inverted U-shaped plate 253 is used to support the magazine 1. The provision of the inverted U-shaped plate 253 can improve the bending strength and wear resistance of both the left support plate 251 and the right support plate 252, so that both the left support plate 251 and the right support plate 252 can reliably support the magazine 1.

[0081] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
