DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1It is shown that an automated loading and unloading jig for granular batch anodes includes a jig body 1 located in the loading and unloading equipment, an X-axis transfer assembly and a Y-axis transfer assembly are installed in the loading and unloading equipment, the Y-axis transfer assembly is installed on the X-axis transfer assembly, and the jig body 1 is fixedly connected to the lower end of the Y-axis transfer assembly.

[0033] like Figure 2-3 The fixture body 1 includes a top plate 11, two side plates 12 fixedly connected to the left and right lower ends of the top plate 11, a suction and discharge 2 and an air guide plate 4 are fixedly connected between the two side plates 12, and a plurality of gas strips are fixedly connected to the lower end of the air guide plate 4, such as Figure 4 The air strip includes a positioning strip 53 fixedly connected to the air guide plate 4 by bolts and a plurality of negative pressure suction nozzles 52 respectively fixedly passing through the positioning strip 53; a plurality of air collecting hoods 3 respectively corresponding to the plurality of air strips are fixedly connected between the air guide plate 4 and the suction and discharge 2; the suction and discharge 2 includes an upper suction plate 21 and an air equalizing row 22 fixed to the lower end of the upper suction plate 21 by bolts; a plurality of pairs of negative pressure tubes 51 are fixedly passed through the upper suction plate 21; a plurality of air holes respectively corresponding to the plurality of negative pressure tubes 51 are drilled on the top plate 11; a plurality of air equalizing grooves and air equalizing long holes are respectively drilled on the air equalizing row 22 and the air guide plate 4; a plurality of evenly distributed air guide holes are also drilled at the bottom of the air equalizing groove; the upper end of the negative pressure suction nozzle 52 extends into the air equalizing long hole; a plurality of pairs of negative pressure tubes 51 They correspond to multiple gas strips respectively, and the two are connected in turn through the gas equalizing groove, gas guide holes, gas gathering hood 3 and the gas equalizing long hole. When in use, the air pipe of the negative pressure equipment is connected to the top of the negative pressure tube 51. When the workpiece is adsorbed, the negative pressure equipment works. At this time, the gas enters the negative pressure equipment through the negative pressure suction nozzle 52, the gas guide holes, the gas gathering hood 3, the gas equalizing groove and the negative pressure tube 51 in turn, so as to realize the adsorption of a single small workpiece, and then realize the simultaneous loading and unloading of multiple columns of workpieces on the hanger, and each gas strip can be controlled separately, so that multiple small workpieces in each column of workstations are used as an adsorption unit. When the negative pressure system is abnormal, it is not easy to cause simultaneous abnormality of multiple columns of small workpieces, which effectively reduces the impact range of the abnormality and effectively improves the stability during loading and unloading.

[0034] An annular groove is excavated at the notch of the air equalizing groove, and a sealing ring 23 is placed in the annular groove. The sealing ring 23 contacts the upper suction plate 21, which effectively ensures the sealing between the air equalizing row 22 and the sealing ring 23, so that the negative pressure adsorption of small workpieces is relatively stable, and it is not easy for small workpieces to fall off due to insufficient negative pressure.

[0035] In the above-mentioned automated loading and unloading fixture for batch anodes of granular materials, through the setting of multiple gas strips, one-to-one batch loading and unloading of whole trays can be achieved for multiple rows of workstations on the hanger. Compared with single or multiple loading and unloading in the prior art, the efficiency of loading and unloading is greatly improved, thereby effectively ensuring the efficiency of anode processing of small workpieces.

[0036] The second implementation method:

[0037] This embodiment adds an air layer compensation unit on the basis of the first embodiment, and the rest of the parts are consistent with the first embodiment.

[0038] Figure 5 It is shown that an air layer compensation unit is arranged outside the multiple air strips, and the air layer compensation unit includes two positioning plates 6 respectively fixedly connected to the left and right lower ends of the positioning strip 53, two monitoring strips 7 fixedly connected between the two positioning plates 6, and multiple compensation sleeves 8 respectively fixedly sleeved on the negative pressure suction nozzles 52 under the positioning strips 53, and the two monitoring strips 7 are respectively located on the front and back sides of the multiple negative pressure suction nozzles 52.

[0039] Figure 6-8 It is shown that the compensation sleeve 8 includes two fixed rings 81 fixedly sleeved outside the negative pressure suction nozzle 52, two guide rods 82 fixedly connected to the upper end of the lower fixed ring 81, and an outer limiting sleeve 83 sleeved on the outer end of the guide rod 82, and the two outer limiting sleeves 83 correspond to the two monitoring strips 7 respectively, the outer limiting sleeve 83 is located between the two fixed rings 81, the guide rod 82 movably passes through the upper fixed ring 81 and extends to the top of the fixed ring 81, and the ends of the two outer limiting sleeves 83 away from each other are fixedly connected with a connecting rod 84, and the lower end of the connecting rod 84 extends into the monitoring strip 7.

[0040] It is worth noting that the negative pressure suction nozzle 52 between the two fixing rings 81 is made of a flexible sealing material.

[0041] The outer limiting sleeve 83 is fixedly connected to the lower fixing ring 81, and the upper end of the outer limiting sleeve 83 does not contact the upper outer limiting sleeve 83, and a 5-10mm gap is left between the two. When negative pressure adsorption of small workpieces is performed for loading and unloading, especially in the process of adsorption and then loading, when there is a certain height difference between the positions of multiple small workpieces, the workpiece at a high place will be adsorbed by the negative pressure suction nozzle 52 first. At this time, the mouth of the negative pressure suction nozzle 52 is blocked by the small workpiece. At this time, the flexible part of the negative pressure suction nozzle 52 will be deformed under the action of negative pressure, and move upward under the guidance of the guide rod 82. The reserved gap allows the negative pressure suction nozzle 52 to drive the small workpiece to move upward to achieve position compensation, thereby not affecting the adsorption of other negative pressure suction nozzles 52 on small workpieces at lower positions, and effectively avoiding the situation where the position offset occurs during adsorption due to the large distance between the negative pressure suction nozzle 52 and the small workpiece, thereby effectively ensuring the subsequent stable loading, and not easy to cause the small workpiece position offset to cause the problem of difficulty in stably loading onto the fixture of the hanger.

[0042] In addition, when the small workpiece is not successfully adsorbed, that is, when empty adsorption occurs, the negative pressure on the corresponding negative pressure suction nozzle 52 in the vertical direction changes little or does not change, which makes its position obviously different from other negative pressure suction nozzles 52 that stably adsorb small workpieces.

[0043] It is worth noting that in order to ensure that the infrared rangefinder 10 can judge the position of the negative pressure suction nozzle 52 more accurately, the installation method of the infrared rangefinder 10 on the monitoring slot 701 can be selectively changed so that it is installed on the vertical inner wall of the monitoring slot 701 through a vertical electric slide rail, and at the same time, the positioning segment 91 is raised so that its upper end is flush with the upper surface of the monitoring strip 7, and the follower segment 92 is also in contact with the bottom of the monitoring slot 701 in a relaxed state. During monitoring, the control system of the loading and unloading equipment can control the infrared rangefinder 10 to move the cabinet up and down through the vertical electric slide rail to monitor whether the follower segment 92 is fully pulled up or only slightly pulled up.

[0044] Furthermore, when all the negative pressure suction nozzles 52 adsorb small workpieces, the multiple negative pressure suction nozzles 52 are displaced in the longitudinal direction with reserved gaps. At this time, the heights of the multiple small workpieces after adsorption are consistent, which facilitates the subsequent stable transfer to the hanger.

[0045] like Figure 9-10 A monitoring groove 701 is excavated in the middle of the upper end of the monitoring strip 7, and the depth of the monitoring groove 701 is not greater than the reserved gap. A sensing unit follower strip 9 is fixedly connected to the bottom of the monitoring groove 701. An infrared rangefinder 10 is fixedly installed on one of the vertical inner walls of the monitoring groove 701. The sensing unit includes a plurality of positioning segments 91 fixedly connected to the bottom of the monitoring groove 701 and a plurality of follower segments 92 respectively fixedly connected between two adjacent positioning segments 91. The lower ends of the plurality of linkage rods 84 are respectively fixedly connected to the middle of the plurality of follower segments 92. When the negative pressure suction nozzle 52 adsorbs a small workpiece for loading or unloading, as shown in FIG. Fig.11 After the small workpiece is adsorbed, when the lower part of the negative pressure suction nozzle 52 moves upward under the action of negative pressure, it will pull the follower segment 92 and lift it from the middle, thereby moving away from the distance between the two follower segments 92. Fig.12 When empty loading occurs, the lower end of the corresponding negative pressure suction nozzle 52 does not move up or moves up very little. At this time, the follower section 92 is not lifted, so it continues to block the infrared rangefinder 10, so that the data obtained is small. According to the data on the infrared rangefinder 10, the control system of the loading and unloading equipment can automatically determine that an abnormality has occurred, so as to facilitate timely detection and corresponding processing, and effectively avoid continuous abnormal loading and unloading.

[0046] The positioning segment 91 is a hard transparent structure, and the following segment 92 is made of a flexible non-transparent material. When the negative pressure suction nozzle 52 is not loading or unloading, the following segment 92 is in a relaxed state and in contact with the bottom of the monitoring slot 701. The transmitting end of the infrared rangefinder 10 is lower than the highest point of the following bar 9, which effectively ensures that when it is not working or the corresponding negative pressure suction nozzle 52 does not adsorb small workpieces, the following segment 92 located downwardly relaxed between the two positioning segments 91 can just block the laser beam emitted by the infrared rangefinder 10, and the transparent material of the positioning segment 91 prevents it from blocking the laser. When the following segment 92 moves up and does not block it, it can pass through multiple positioning segments 91 to generate larger data.

[0047] The bottom of the monitoring groove 701 is an inverted trapezoidal structure. The positioning section 91 is completely matched with the bottom of the monitoring groove 701, and the maximum width of the positioning section 91 is not greater than twice the outer diameter of the follower section 92, which effectively ensures that the follower section 92 in a relaxed state can stably block the laser beam when it falls on the bottom of the monitoring groove 701.

[0048] In summary, in the above-mentioned automated loading and unloading fixture for batch anodes of granular materials, through the setting of multiple air strips, one-to-one batch loading and unloading of whole trays can be realized for multiple rows of workstations on the hanger. Compared with the single or multiple loading and unloading in the prior art, the efficiency of loading and unloading is greatly improved, thereby effectively ensuring the efficiency of anode processing of small workpieces. In addition, through the setting of the air layer compensation unit on each air strip, a certain compensation space can be reserved. During loading and unloading, the air strip can adapt to small workpieces with certain differences in height, thereby effectively ensuring that multiple negative pressure suction nozzles 52 can adsorb small workpieces during loading and unloading, and empty loading or unloading is not likely to occur, further improving the loading and unloading efficiency. In addition, the air layer compensation unit can also monitor whether the negative pressure suction nozzle 52 is sucking material, so as to detect abnormalities in time, so as to take corresponding measures in time, and effectively avoid continuous abnormal loading and unloading.

[0049] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
