[0030] like Figure 1 , 2As shown in Figure 3, the utility model provides an automatic loading and unloading conveying mechanism for drill needles, comprising a cabinet 1, on which a conveyor belt module 2 for conveying a drill needle material box 31 is arranged, and below the conveyor belt module 2 is a storage bin 3 for placing a material box 31 (including a material box 31 for drill needles to be ground and ground) (the storage bin 3 can be a single layer or multiple layers, such as Fig. 9 As shown, in this embodiment, the storage bin 3 is arranged with 12 layers, each layer can hold 10 material boxes 31, each material box 31 can hold 50 drill needles, and a total of 6000 drill needles can be accommodated at one time); at the same time, the head and tail ends of the conveyor belt module 2 (referring to the two ends along the movement direction of the conveyor belt module 2) are respectively provided with a loading ladder 42 and a unloading ladder 43, the loading ladder 42 is used to transport the material to be ground in the storage bin 3 to the conveyor belt module 2, and the unloading ladder 43 is used to The ground material in the conveyor belt module 2 is sent back to the storage bin 3, and the loading ladder 42 and the unloading ladder 43 can be lifted and lowered along the height direction of the storage bin 3 and the conveyor belt module 2 (the loading ladder 42 and the unloading ladder 43 can be lifted and lowered at the same time, or can not be lifted and lowered at the same time), and the loading box 31 and the unloading box 31 can be performed at the storage bin 3 (the loading box 31 and the unloading box 31 can be performed at the same time, or the loading box 31 can be performed first and then the unloading box 31, or the unloading box 31 can be performed first and then the loading box 31).

[0031] The automatic loading and unloading conveying mechanism for drill bits with the above structure can store a large number of drill bits to be ground and ground by arranging a storage bin 3 for placing a material box 31 under the conveyor belt module 2; at the same time, by arranging a loading ladder 42 and a unloading ladder 43 at the head and tail ends of the conveyor belt module 2 respectively, the loading ladder 42 and the unloading ladder 43 can be lifted and lowered along the height direction of the storage bin 3 and the conveyor belt module 2, and the loading box 31 and the unloading box 31 can be performed at the storage bin 3, so that the material to be ground in the storage bin 3 can be transported to the conveyor belt module 2, and the ground material in the conveyor belt module 2 can be sent back to the storage bin 3; therefore, the storage space of the grinding material box 31 in the automatic loading and unloading conveying mechanism for drill bits can be increased, the frequency of manual loading and unloading can be reduced, and the situation of the drill bit grinding equipment waiting for material and stopping due to untimely manual loading and unloading can be reduced.

[0032] In some embodiments, the loading ladder 42, the unloading ladder 43, the loading and unloading fixed frame 41, and the lifting mechanism 44 together constitute an loading and unloading module 4; the loading ladder 42 and the unloading ladder 43 are installed on the loading and unloading fixed frame 41, and the lifting mechanism 44 includes a loading lifting mechanism and a unloading lifting mechanism that can respectively control the loading ladder 42 and the unloading ladder 43 to move up and down along the height direction of the loading and unloading fixed frame 41; the loading ladder 42 is provided with a loading chuck, which can clamp the material box of the drill bit to be ground in the storage bin 3 onto the loading ladder 42; the unloading ladder 43 is provided with a unloading chuck, which can clamp the material box of the ground drill bit in the unloading ladder 43 onto the storage bin 3.

[0033] The automatic loading and unloading conveying mechanism for drill bits of the above structure can control the loading ladder 42 and the unloading ladder 43 to move up and down along the height direction of the loading and unloading fixed frame 41 through the loading lifting mechanism and the unloading lifting mechanism respectively, and can clamp the material box of the drill bits to be ground in the storage bin 3 onto the loading ladder 42 and the material box of the ground drill bits in the unloading ladder 43 onto the storage bin 3 through the loading chuck and the unloading chuck respectively, thereby realizing loading and unloading, and reducing the frequency of manual loading and unloading.

[0034] In some embodiments, Figure 4 As shown, the loading ladder 42, the unloading ladder 43, the loading and unloading fixed frame 41, and the lifting mechanism 44 together constitute the loading and unloading module 4; the loading ladder 42 and the unloading ladder 43 are installed on the loading and unloading fixed frame 41, and the lifting mechanism 44 can control the loading ladder 42 and the unloading ladder 43 to move up and down along the height direction of the loading and unloading fixed frame 41 at the same time; the unloading ladder 43 is provided with a unloading pushing mechanism 45 which pushes toward the storage bin 3, and can push the ground drill bit box placed on the unloading ladder 43 onto the storage bin 3.

[0035] With the automatic loading and unloading conveying mechanism for drill bits of the above structure, when a full material box 31 is placed in the material storage bin 3, the material unloading pushing mechanism 45 pushes the ground drill bit material box 31 on the unloading ladder 43 onto the material storage bin 3. Since the material storage bin 3 is full and has no free space, when the ground drill bit material box 31 is pushed onto the material storage bin 3, a box of drill bit material box 31 to be ground will be pushed onto the loading ladder 42 at the other end of the material storage bin 3 at the same time. This allows the loading box 31 and the unloading box 31 to be simultaneously loaded into the material storage bin 3. By adopting a lifting mechanism 44 and a unloading pushing mechanism 45, loading and unloading can be achieved simultaneously without separating different lifting mechanisms and pushing mechanisms to control loading and unloading respectively, thereby simplifying the structure and saving costs.

[0036] In some embodiments, the lifting mechanism 44 includes two lifting chutes 441, two lifting sliders 442, and a lifting power assembly 443 for controlling the two lifting sliders 442 to slide on the corresponding lifting chutes 441 at the same time, and the loading ladder 42 and unloading ladder 43 are respectively fixed on the two lifting sliders 442, and the lifting power assembly 443 can be a common power assembly such as a motor and a cylinder. Preferably, a motor is used to control the up and down movement of the lifting slider 442, and the movement displacement has a higher precision, and more precise control can be achieved, so that when the storage bin 3 is multi-layered, the loading ladder 42 and the unloading ladder 43 can be accurately controlled to stay at the corresponding storage layer for loading and unloading boxes 31 and 31, avoiding the failure of the loading and unloading boxes caused by inaccurate positioning of the upper and lower positions.

[0037] By adopting the automatic loading and unloading conveying mechanism for the drill bit with the above structure, the lifting slider 442 is controlled to move up and down along the lifting slot 441 through the lifting power component 443, so that the loading ladder 42 and the unloading ladder 43 can be controlled to move up and down and reciprocate between the storage bin 3 and the conveyor belt module 2, thereby realizing the transmission of the material box 31 between the storage bin 3 and the conveyor belt module 2.

[0038] In some embodiments, the unloading pushing mechanism 45 includes a unloading pushing plate 451 and a unloading pushing cylinder 452. The unloading pushing plate 451 is arranged at one end of the unloading ladder 43 away from the storage bin 3. The unloading pushing cylinder 452 can control the unloading pushing plate 451 to move toward the storage bin 3.

[0039] The automatic loading and unloading conveying mechanism of the drill bit with the above structure is adopted. The unloading pushing plate 451 moves toward the storage bin 3 under the control of the unloading pushing cylinder 452, so that the ground material box 31 placed on the unloading ladder 43 can be pushed onto the storage bin 3 to complete the unloading action of the material box 31.

[0040] In some embodiments, the automatic loading and unloading conveying mechanism for the drill bit further includes a loading and pushing mechanism 46, which is used to push the material box 31 on the loading ladder 42 onto the conveyor module 2 when the loading ladder 42 rises to the height of the conveyor module 2. Therefore, the loading and pushing mechanism 46 can be set on the loading ladder 42, or at other positions near one end of the loading box of the conveyor module 2, as long as it can achieve the goal of pushing the material box 31 on the loading ladder 42 onto the conveyor module 2.

[0041] The automatic loading and unloading conveying mechanism of the drill bit with the above structure adopts the loading and pushing mechanism 46 to push the material box 31 on the loading ladder 42 onto the conveyor belt module 2, avoiding manual handling and improving the loading efficiency.

[0042] In some embodiments, the loading and pushing mechanism 46 includes a loading and pushing plate 461 and a loading and pushing cylinder 462 , and the loading and pushing cylinder 462 can control the loading and pushing plate 461 to move toward the conveyor belt module 2 .

[0043] The automatic loading and unloading conveying mechanism of the drill bit with the above structure is adopted. The loading push plate 461 moves toward the conveyor belt module 2 under the control of the loading push cylinder 462, so that the material box 31 to be ground placed on the loading ladder 42 can be pushed onto the conveyor belt module 2 for subsequent grinding processing operations.

[0044] In some embodiments, Figure 5 As shown, the conveyor belt module 2 includes a conveyor belt frame 21, a conveyor belt 22 and a rotating shaft 23. The conveyor belt 22 and the rotating shaft 23 are arranged in the conveyor belt frame 21, and the rotating shaft 23 can control the movement of the conveyor belt 22.

[0045] With the automatic loading and unloading conveying mechanism for drill bits of the above structure, after the drill bit box 31 to be ground is pushed from the loading ladder 42 onto the conveyor belt 22 , it can be conveyed to the corresponding grinding processing position under the control of the rotating shaft 23 .

[0046] In some embodiments, Figure 6 As shown, the automatic loading and unloading conveying mechanism for the drill bit also includes a material blocking module 5, which is arranged on the cabinet 1, so that the material box 31 can be fixed on the conveyor belt module; the material blocking module 5 includes a material blocking bottom plate 51, and a front baffle mechanism 52 is installed on the material blocking bottom plate 51, which can move to the front of the material box 31 (referring to the front along the moving direction of the conveyor belt 22) and resist the movement of the material box 31 on the conveyor belt 22 along the forward direction of the conveyor belt 22; the front baffle mechanism 52 can move laterally from the left / right side of the material box 31 to the front of the material box 31, and can also move longitudinally from the upper / lower side of the material box 31 to the front of the material box 31.

[0047] With the automatic loading and unloading conveying mechanism for drill bits of the above structure, when the drill bit material box 31 to be ground is conveyed to the corresponding grinding processing position on the conveyor belt 22, the front baffle mechanism 52 moves to the front of the material box 31 to block the material box 31 and stop it from moving forward on the conveyor belt 22 so as to carry out the corresponding grinding processing process.

[0048] In some embodiments, the front baffle mechanism 52 includes a front baffle 521 located above the conveyor belt 22 and a front baffle cylinder 522 for controlling the front baffle 521 to move left and right along a direction perpendicular to the forward direction of the conveyor belt 22. The front baffle 521 is located on the left or right side of the material box 31, and under the control of the front baffle cylinder 522, it moves horizontally to the front of the material box 31, which can resist the material box 31 and stop it from moving forward on the conveyor belt 22 so as to carry out the corresponding grinding processing process.

[0049] In some embodiments, the front baffle mechanism 52 includes a front baffle 521 arranged between the two conveyor belts 22 and a front baffle cylinder 522 for controlling the front baffle 521 to make a lifting movement in the longitudinal direction; the front baffle 521 can be arranged above the material box 31, and under the control of the front baffle cylinder 522, the front baffle 521 moves downward to the front of the material box 31; or when the conveyor belt 22 is two conveyor belts 22 arranged at intervals, the front baffle 521 can also be arranged below the material box 31, and under the control of the front baffle cylinder 522, the front baffle 521 moves upward to the front of the material box 31; thereby, the material box 31 can be blocked and stopped from moving forward on the conveyor belt 22 so as to carry out the corresponding grinding processing process.

[0050] In some embodiments, along the advancing direction of the conveyor belt 22, the side of the conveyor belt 22 is provided with a side baffle mechanism 53 that can block the material box 31 from moving left / right on the conveyor belt 22 in a direction perpendicular to the advancing direction of the conveyor belt 22, and the side baffle mechanism 53 is installed on the material blocking bottom plate 51. The side baffle mechanism 53 can be provided on only one side (left or right) of the conveyor belt 22, or on both sides of the conveyor belt 22.

[0051] With the automatic loading and unloading conveying mechanism for drill bits of the above structure, when the drill bit box 31 to be ground is blocked by the front baffle mechanism 52 on the conveyor belt 22 and stops moving forward, the side baffle mechanism 53 can further prevent the box 31 from moving left and right, thereby further improving the accuracy of taking and delivering the drill bits.

[0052] In some embodiments, along the forward direction of the conveyor belt 22, a frame baffle 24 higher than the conveyor belt 22 and in contact with the side of the material box 31 is provided on one side of the conveyor belt 22, and the side baffle mechanism 53 is provided on the other side.

[0053] With the automatic loading and unloading conveying mechanism for drill needles of the above structure, when the drill needle box 31 to be ground is blocked by the front baffle mechanism 52 on the conveyor belt 22 and stops moving forward, the side baffle mechanism 53 moves toward the frame baffle 24 to press the box 31 against the frame baffle 24, which can further prevent the box 31 from moving left and right, and further improve the accuracy of taking and sending the drill needles; at the same time, compared with only setting the side baffle mechanism 53 on one side of the conveyor belt 22, the pressing effect is better, and thus the accuracy of taking and sending the drill needles is higher; compared with setting the side baffle mechanism 53 on both sides of the conveyor belt 22, the structure is simpler and the cost is lower.

[0054] In some embodiments, the side baffle mechanism 53 includes a side baffle 531 that is higher than the conveyor belt 22 and a side baffle cylinder 532 that controls the side baffle 531 to move toward the conveyor belt 22 .

[0055] With the automatic loading and unloading conveying mechanism for drill bits of the above structure, when the drill bit material box 31 to be ground is blocked by the front baffle mechanism 52 on the conveyor belt 22 and stops moving forward, the side baffle 531 moves toward the conveyor belt 22 under the control of the side baffle cylinder 532, pressing the material box 31 to prevent it from moving left and right, thereby further improving the accuracy of taking and delivering the drill bits.

[0056] In some embodiments, a first linear moving module 55 is disposed at the bottom of the material blocking bottom plate 51 along the advancing direction of the conveyor belt 22 , and the material blocking bottom plate 51 can move linearly on the first linear moving module 55 .

[0057] By adopting the automatic loading and unloading conveying mechanism for drill bits with the above structure, the material blocking base plate 51 can move linearly on the first linear moving module 55, and then the front baffle mechanism 52 and the side baffle mechanism 53 installed on the material blocking base plate 51 can also move linearly on the first linear moving module 55, so that the position where the material box 31 stays on the conveyor belt 22 can be changed, which increases the flexibility of taking and delivering the drill bits and improves the drill bit grinding efficiency.

[0058] In some embodiments, a defective product placement area 54 is further provided on the material blocking bottom plate 51 , and the defective product placement area 54 is arranged on the outer side of the conveyor belt frame 21 .

[0059] The automatic loading and unloading conveying mechanism for drill bits with the above structure is provided with an additional defective product placement area 54 for placing drill bits that are not ground properly.

[0060] In some embodiments, Figure 7 , 8As shown, a material picking and feeding module 6 is also arranged above the material blocking module 5, and the material picking and feeding module 6 includes a material picking and feeding fixed frame 61 arranged on the cabinet 1, and a material picking and feeding chuck group 62 arranged on the material picking and feeding fixed frame 61. The material picking and feeding chuck group 62 can be raised and lowered on the material picking and feeding fixed frame 61, and can clamp or release the drill needle in the material box 31.

[0061] The automatic loading and unloading conveying mechanism for drill needles of the above structure can take and put the drill needles in the material box 31 on the conveyor belt 22 through the feeding module 6, so that the drill needles can be taken out for grinding and the ground drill needles can be put back into the material box 31.

[0062] In some embodiments, a second linear movable module 63 is further disposed on the feeding and picking fixed frame 61 . The second linear movable module 63 is perpendicular to the first linear movable module 55 , and the feeding and picking chuck group 62 can move linearly on the second linear movable module 63 .

[0063] The automatic loading and unloading conveying mechanism for drill bits with the above structure is adopted, and the feeding and picking up chuck group 62 can move linearly on the second linear moving module 63. When there is an unqualified drill bit, the feeding and picking up chuck group 62 moves to the top of the defective product placement area 54, and then the feeding and picking up chuck group 62 is lowered and released, so that the unqualified drill bit can be placed in the defective product placement area 54.

[0064] In some embodiments, the loading and pushing mechanism 46 is arranged on the feeding and picking fixed frame 61. When the loading ladder 42 rises to the height of the conveyor belt 22, the loading and pushing mechanism 46 pushes the material box 31 on the loading ladder 42 onto the conveyor belt 22, avoiding manual handling and improving the efficiency of loading. At the same time, compared with the scheme in which the loading and pushing mechanism 46 is arranged on the loading ladder 42, the loading and pushing mechanism 46 does not need to move up and down with the loading ladder 42, avoiding the position change of the loading and pushing mechanism 46 due to frequent up and down movements, thereby affecting the loading and pushing mechanism 46 to push the material box 31 onto the conveyor belt 22.

[0065] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All equivalent changes made based on the shape, structure and principle of the present invention should be included in the protection scope of the present invention.
